true |
additionalAnnotations | map[string]string |
Additional Annotations allows to define additional labels that will be included in all objects created by the operator. Note, user can override values set by default from the cass-operator and doing so could break cass-operator functionality. |
false |
additionalLabels | map[string]string |
Additional Labels allows to define additional labels that will be included in all objects created by the operator. Note, user can override values set by default from the cass-operator and doing so could break cass-operator functionality. |
false |
additionalSeeds | []string |
|
false |
additionalServiceConfig | object |
AdditionalServiceConfig allows to define additional parameters that are included in the created Services. Note, user can override values set by cass-operator and doing so could break cass-operator functionality.
Avoid label "cass-operator" and anything that starts with "cassandra.datastax.com/" |
false |
allowMultipleNodesPerWorker | boolean |
Turning this option on allows multiple server pods to be created on a k8s worker node, by removing the default pod anti affinity rules.
By default the operator creates just one server pod per k8s worker node. Using custom affinity rules might require turning this
option on in which case the defaults are not set. |
false |
canaryUpgrade | boolean |
Indicates that configuration and container image changes should only be pushed to
the first rack of the datacenter |
false |
canaryUpgradeCount | integer |
The number of nodes that will be updated when CanaryUpgrade is true. Note that the value is
either 0 or greater than the rack size, then all nodes in the rack will get updated. Format: int32 |
false |
cdc | object |
CDC allows configuration of the change data capture agent which can run within the Management API container. Use it to send data to Pulsar. |
false |
config | string |
Config for the server, in YAML format Format: byte |

configBuilderImage | string |
Container image for the config builder init container. Overrides value from ImageConfig ConfigBuilderImage |
false |
configBuilderResources | object |
Kubernetes resource requests and limits per server config initialization container. |
false |
configSecret | string |
ConfigSecret is the name of a secret that contains configuration for Cassandra. The
secret is expected to have a property named config whose value should be a JSON
formatted string that should look like this:
config: |- { “cassandra-yaml”: { “read_request_timeout_in_ms”: 10000 }, “jmv-options”: { “max_heap_size”: 1024M } } ConfigSecret is mutually exclusive with Config. ConfigSecret takes precedence and
will be used exclusively if both properties are set. The operator sets a watch such
that an update to the secret will trigger an update of the StatefulSets. |
false |
datacenterName | string |
DatacenterName allows to override the name of the Cassandra datacenter. Kubernetes objects will be named after a sanitized version of it if set, and if not metadata.name. In Cassandra the DC name will be overridden by this value.
It may generate some confusion as objects created for the DC will have a different name than the CasandraDatacenter object itself.
This setting can create conflicts if multiple DCs coexist in the same namespace if metadata.name for a DC with no override is set to the same value as the override name of another DC.
Use cautiously. |
false |
disableSystemLoggerSidecar | boolean |
Configuration for disabling the simple log tailing sidecar container. Our default is to have it enabled. |

Rack names in this list are set to the latest StatefulSet configuration
even if Cassandra nodes are down. Use this to recover from an upgrade that couldn’t
roll out. |
false |
managementApiAuth | object |
Config for the Management API certificates |
false |
minReadySeconds | integer |
MinReadySeconds sets the minimum number of seconds for which a newly created pod should be ready without any of its containers crashing, for it to be considered available. Defaults to 5 seconds and is set in the StatefulSet spec.
Setting to 0 might cause multiple Cassandra pods to restart at the same time despite PodDisruptionBudget settings. Format: int32 |
false |
networking | object |
|
false |
nodeAffinityLabels | map[string]string |
NodeAffinityLabels to pin the Datacenter, using node affinity |

podTemplateSpec | object |
PodTemplate provides customisation options (labels, annotations, affinity rules, resource requests, and so on) for the cassandra pods |
false |
racks | []object |
A list of the named racks in the datacenter, representing independent failure domains. The
number of racks should match the replication factor in the keyspaces you plan to create, and
the number of racks cannot easily be changed once a datacenter is deployed. |

This value will override anything set in the ImageConfig matching the ServerVersion
More info: https://kubernetes.io/docs/concepts/containers/images |
false |
serviceAccount | string |
Deprecated DeprecatedServiceAccount Use ServiceAccountName instead, which takes precedence. The k8s service account to use for the server pods |
false |
serviceAccountName | string |
ServiceAccountName is the Kubernetes service account to use for the server pods. This takes presedence over DeprecatedServiceAccount and both take precedence over
setting it in the PodTemplateSpec. |
false |
stopped | boolean |
A stopped CassandraDatacenter will have no running server pods, like using “stop” with
traditional System V init scripts. Other Kubernetes resources will be left intact, and volumes
will re-attach when the CassandraDatacenter workload is resumed. |
false |
superuserSecretName | string |
This secret defines the username and password for the Cassandra server superuser.

Name | Type | Description | Required |
---|---|---|---|
mountPath | string |
Mount path into cassandra container |
true |
name | string |
Name of the pvc / volume |
true |
pvcSpec | object |
PVCSpec is a persistent volume claim spec. Either this or VolumeSource is required. |
false |
volumeSource | object |
VolumeSource to mount the volume from (such as ConfigMap / Secret). This or PVCSpec is required. |
false |
CassandraDatacenter.spec.storageConfig.additionalVolumes[index].pvcSpec
PVCSpec is a persistent volume claim spec. Either this or VolumeSource is required.
Name | Type | Description | Required |
---|---|---|---|
accessModes | []string |
accessModes contains the desired access modes the volume should have.
More info: https://kubernetes.io/docs/concepts/storage/persistent-volumes#access-modes-1 |
false |
dataSource | object |
dataSource field can be used to specify either:
* An existing VolumeSnapshot object (snapshot.storage.k8s.io/VolumeSnapshot)
* An existing PVC (PersistentVolumeClaim)
If the provisioner or an external controller can support the specified data source,
it will create a new volume based on the contents of the specified data source.
When the AnyVolumeDataSource feature gate is enabled, dataSource contents will be copied to dataSourceRef,
and dataSourceRef contents will be copied to dataSource when dataSourceRef.namespace is not specified.
If the namespace is specified, then dataSourceRef will not be copied to dataSource. |
false |
dataSourceRef | object |
dataSourceRef specifies the object from which to populate the volume with data, if a non-empty
volume is desired. This may be any object from a non-empty API group (non
core object) or a PersistentVolumeClaim object.
When this field is specified, volume binding will only succeed if the type of
the specified object matches some installed volume populator or dynamic
provisioner.
This field will replace the functionality of the dataSource field and as such
if both fields are non-empty, they must have the same value. For backwards
compatibility, when namespace isn't specified in dataSourceRef,
both fields (dataSource and dataSourceRef) will be set to the same
value automatically if one of them is empty and the other is non-empty.
When namespace is specified in dataSourceRef,
dataSource isn't set to the same value and must be empty.
There are three important differences between dataSource and dataSourceRef:
* While dataSource only allows two specific types of objects, dataSourceRef
allows any non-core object, as well as PersistentVolumeClaim objects.
* While dataSource ignores disallowed values (dropping them), dataSourceRef
preserves all values, and generates an error if a disallowed value is
specified.
* While dataSource only allows local objects, dataSourceRef allows objects
in any namespaces.
(Beta) Using this field requires the AnyVolumeDataSource feature gate to be enabled.
(Alpha) Using the namespace field of dataSourceRef requires the CrossNamespaceVolumeDataSource feature gate to be enabled. |
false |
resources | object |

If RecoverVolumeExpansionFailure feature is enabled users are allowed to specify resource requirements
that are lower than previous value but must still be higher than capacity recorded in the
status field of the claim.
More info: https://kubernetes.io/docs/concepts/storage/persistent-volumes#resources |
false |
selector | object |
selector is a label query over volumes to consider for binding. |
false |
storageClassName | string |
storageClassName is the name of the StorageClass required by the claim.
More info: https://kubernetes.io/docs/concepts/storage/persistent-volumes#class-1 |
false |
volumeAttributesClassName | string |
volumeAttributesClassName may be used to set the VolumeAttributesClass used by this claim.
If specified, the CSI driver will create or update the volume with the attributes defined
in the corresponding VolumeAttributesClass. This has a different purpose than storageClassName,
it can be changed after the claim is created. An empty string value means that no VolumeAttributesClass
will be applied to the claim but it's not allowed to reset this field to empty string once it is set.
If unspecified and the PersistentVolumeClaim is unbound, the default VolumeAttributesClass
will be set by the persistentvolume controller if it exists.
If the resource referred to by volumeAttributesClass does not exist, this PersistentVolumeClaim will be
set to a Pending state, as reflected by the modifyVolumeStatus field, until such as a resource
exists.
More info: https://kubernetes.io/docs/concepts/storage/persistent-volumes#volumeattributesclass
(Alpha) Using this field requires the VolumeAttributesClass feature gate to be enabled. |
false |

Value of Filesystem is implied when not included in claim spec. |
false |
volumeName | string |
volumeName is the binding reference to the PersistentVolume backing this claim. |
false |
CassandraDatacenter.spec.storageConfig.additionalVolumes[index].pvcSpec.dataSource

ephemeral | object |
ephemeral represents a volume that is handled by a cluster storage driver.
The volume's lifecycle is tied to the pod that defines it - it will be created before the pod starts,
and deleted when the pod is removed.
Use this if: a) the volume is only needed while the pod runs, b) features of normal volumes like restoring from snapshot or capacity tracking are needed, c) the storage driver is specified through a storage class, and d) the storage driver supports dynamic volume provisioning through a PersistentVolumeClaim (see EphemeralVolumeSource for more information on the connection between this volume type and PersistentVolumeClaim). Use PersistentVolumeClaim or one of the vendor-specific APIs for volumes that persist for longer than the lifecycle of an individual pod. Use CSI for light-weight local ephemeral volumes if the CSI driver is meant to be used that way - see the documentation of the driver for more information. A pod can use both types of ephemeral volumes and
persistent volumes at the same time. |

CassandraDatacenter.spec.storageConfig.additionalVolumes[index].volumeSource.ephemeral
ephemeral represents a volume that is handled by a cluster storage driver. The volume’s lifecycle is tied to the pod that defines it - it will be created before the pod starts, and deleted when the pod is removed.
Use this if: a) the volume is only needed while the pod runs, b) features of normal volumes like restoring from snapshot or capacity tracking are needed, c) the storage driver is specified through a storage class, and d) the storage driver supports dynamic volume provisioning through a PersistentVolumeClaim (see EphemeralVolumeSource for more information on the connection between this volume type and PersistentVolumeClaim).
Use PersistentVolumeClaim or one of the vendor-specific APIs for volumes that persist for longer than the lifecycle of an individual pod.
Use CSI for light-weight local ephemeral volumes if the CSI driver is meant to be used that way - see the documentation of the driver for more information.
A pod can use both types of ephemeral volumes and persistent volumes at the same time.
Name | Type | Description | Required |

Starting the pod is then blocked until the unrelated PVC is removed. If such a pre-created PVC is meant to be used by the pod, the PVC has to updated with an owner reference to the pod once the pod exists. Normally this should not be necessary, but it may be useful when manually reconstructing a broken cluster. This field is read-only and no changes will be made by Kubernetes to the PVC after it has been created. Required, must not be nil. |

pod. The name of the PVC will be <pod name>-<volume name>
where
<volume name>
is the name from the PodSpec.Volumes
array
entry. Pod validation will reject the pod if the concatenated name
is not valid for a PVC (for example, too long).
An existing PVC with that name that is not owned by the pod will not be used for the pod to avoid using an unrelated volume by mistake. Starting the pod is then blocked until the unrelated PVC is removed. If such a pre-created PVC is meant to be used by the pod, the PVC has to updated with an owner reference to the pod once the pod exists.

dataSource | object |
dataSource field can be used to specify either:
* An existing VolumeSnapshot object (snapshot.storage.k8s.io/VolumeSnapshot)
* An existing PVC (PersistentVolumeClaim)
If the provisioner or an external controller can support the specified data source,
it will create a new volume based on the contents of the specified data source.
When the AnyVolumeDataSource feature gate is enabled, dataSource contents will be copied to dataSourceRef,
and dataSourceRef contents will be copied to dataSource when dataSourceRef.namespace is not specified.
If the namespace is specified, then dataSourceRef will not be copied to dataSource. |
false |
dataSourceRef | object |
dataSourceRef specifies the object from which to populate the volume with data, if a non-empty
volume is desired. This may be any object from a non-empty API group (non
core object) or a PersistentVolumeClaim object.
When this field is specified, volume binding will only succeed if the type of
the specified object matches some installed volume populator or dynamic
provisioner.
This field will replace the functionality of the dataSource field and as such
if both fields are non-empty, they must have the same value. For backwards
compatibility, when namespace isn't specified in dataSourceRef,
both fields (dataSource and dataSourceRef) will be set to the same
value automatically if one of them is empty and the other is non-empty.
When namespace is specified in dataSourceRef,
dataSource isn't set to the same value and must be empty.
There are three important differences between dataSource and dataSourceRef:
* While dataSource only allows two specific types of objects, dataSourceRef
allows any non-core object, as well as PersistentVolumeClaim objects.
* While dataSource ignores disallowed values (dropping them), dataSourceRef
preserves all values, and generates an error if a disallowed value is
specified.
* While dataSource only allows local objects, dataSourceRef allows objects
in any namespaces.

volumeAttributesClassName | string |
volumeAttributesClassName may be used to set the VolumeAttributesClass used by this claim.
If specified, the CSI driver will create or update the volume with the attributes defined
in the corresponding VolumeAttributesClass. This has a different purpose than storageClassName,
it can be changed after the claim is created. An empty string value means that no VolumeAttributesClass
will be applied to the claim but it's not allowed to reset this field to empty string once it is set.
If unspecified and the PersistentVolumeClaim is unbound, the default VolumeAttributesClass
will be set by the persistentvolume controller if it exists.
If the resource referred to by volumeAttributesClass does not exist, this PersistentVolumeClaim will be
set to a Pending state, as reflected by the modifyVolumeStatus field, until such as a resource
exists.

the specified object matches some installed volume populator or dynamic
provisioner.
This field will replace the functionality of the dataSource field and as such
if both fields are non-empty, they must have the same value. For backwards
compatibility, when namespace isn't specified in dataSourceRef,
both fields (dataSource and dataSourceRef) will be set to the same
value automatically if one of them is empty and the other is non-empty.
When namespace is specified in dataSourceRef,
dataSource isn't set to the same value and must be empty.
There are three important differences between dataSource and dataSourceRef:
* While dataSource only allows two specific types of objects, dataSourceRef
allows any non-core object, as well as PersistentVolumeClaim objects.
* While dataSource ignores disallowed values (dropping them), dataSourceRef
preserves all values, and generates an error if a disallowed value is
specified.
* While dataSource only allows local objects, dataSourceRef allows objects
in any namespaces.
(Beta) Using this field requires the AnyVolumeDataSource feature gate to be enabled.
(Alpha) Using the namespace field of dataSourceRef requires the CrossNamespaceVolumeDataSource feature gate to be enabled. |

resources | object |
resources represents the minimum resources the volume should have.
If RecoverVolumeExpansionFailure feature is enabled users are allowed to specify resource requirements
that are lower than previous value but must still be higher than capacity recorded in the
status field of the claim.

false |
storageClassName | string |
storageClassName is the name of the StorageClass required by the claim.
More info: https://kubernetes.io/docs/concepts/storage/persistent-volumes#class-1 |
false |
volumeAttributesClassName | string |
volumeAttributesClassName may be used to set the VolumeAttributesClass used by this claim.
If specified, the CSI driver will create or update the volume with the attributes defined
in the corresponding VolumeAttributesClass. This has a different purpose than storageClassName,
it can be changed after the claim is created. An empty string value means that no VolumeAttributesClass
will be applied to the claim but it's not allowed to reset this field to empty string once it is set.
If unspecified and the PersistentVolumeClaim is unbound, the default VolumeAttributesClass
will be set by the persistentvolume controller if it exists.
If the resource referred to by volumeAttributesClass does not exist, this PersistentVolumeClaim will be
set to a Pending state, as reflected by the modifyVolumeStatus field, until such as a resource
exists.

CassandraDatacenter.spec.storageConfig.cassandraDataVolumeClaimSpec.dataSource
dataSource field can be used to specify either:
- An existing VolumeSnapshot object (snapshot.storage.k8s.io/VolumeSnapshot)
- An existing PVC (PersistentVolumeClaim) If the provisioner or an external controller can support the specified data source, it will create a new volume based on the contents of the specified data source. When the AnyVolumeDataSource feature gate is enabled, dataSource contents will be copied to dataSourceRef, and dataSourceRef contents will be copied to dataSource when dataSourceRef.namespace is not specified. If the namespace is specified, then dataSourceRef will not be copied to dataSource.

CassandraDatacenter.spec.storageConfig.cassandraDataVolumeClaimSpec.dataSourceRef
dataSourceRef specifies the object from which to populate the volume with data, if a non-empty volume is desired. This may be any object from a non-empty API group (non core object) or a PersistentVolumeClaim object. When this field is specified, volume binding will only succeed if the type of the specified object matches some installed volume populator or dynamic provisioner. This field will replace the functionality of the dataSource field and as such if both fields are non-empty, they must have the same value. For backwards compatibility, when namespace isn’t specified in dataSourceRef, both fields (dataSource and dataSourceRef) will be set to the same value automatically if one of them is empty and the other is non-empty. When namespace is specified in dataSourceRef, dataSource isn’t set to the same value and must be empty. There are three important differences between dataSource and dataSourceRef:

false |
setHostnameAsFQDN | boolean |
If true the pod’s hostname will be configured as the pod’s FQDN, rather than the leaf name (the default).
In Linux containers, this means setting the FQDN in the hostname field of the kernel (the nodename field of struct utsname).
In Windows containers, this means setting the registry value of hostname for the registry key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters to FQDN.
If a pod does not have FQDN, this has no effect.
Default to false. |
false |
shareProcessNamespace | boolean |

If specified, the fully qualified Pod hostname will be “ |
false |
terminationGracePeriodSeconds | integer |
Optional duration in seconds the pod needs to terminate gracefully. May be decreased in delete request.
Value must be non-negative integer. The value zero indicates stop immediately via
the kill signal (no opportunity to shut down).
If this value is nil, the default grace period will be used instead.
The grace period is the duration in seconds after the processes running in the pod are sent
a termination signal and the time when the processes are forcibly halted with a kill signal.
Set this value longer than the expected cleanup time for your process.
Defaults to 30 seconds. Format: int64 |

false |
resizePolicy | []object |
Resources resize policy for the container. |
false |
resources | object |
Compute Resources required by this container.
Cannot be updated.
More info: https://kubernetes.io/docs/concepts/configuration/manage-resources-containers/ |
false |
restartPolicy | string |
RestartPolicy defines the restart behavior of individual containers in a pod.
This field may only be set for init containers, and the only allowed value is "Always".
For non-init containers or when this field is not specified,
the restart behavior is defined by the Pod's restart policy and the container type.
Setting the RestartPolicy as "Always" for the init container will have the following effect:
this init container will be continually restarted on
exit until all regular containers have terminated. Once all regular
containers have completed, all init containers with restartPolicy "Always"
will be shut down. This lifecycle differs from normal init containers and
is often referred to as a "sidecar" container. Although this init
container still starts in the init container sequence, it does not wait
for the container to complete before proceeding to the next init
container. Instead, the next init container starts immediately after this
init container is started, or after any startupProbe has successfully
completed. |
false |
securityContext | object |
SecurityContext defines the security options the container should be run with.
If set, the fields of SecurityContext override the equivalent fields of PodSecurityContext.
More info: https://kubernetes.io/docs/tasks/configure-pod-container/security-context/ |
false |
startupProbe | object |
StartupProbe indicates that the Pod has successfully initialized.
If specified, no other probes are executed until this completes successfully.
If this probe fails, the Pod will be restarted, just as if the livenessProbe failed.
This can be used to provide different probe parameters at the beginning of a Pod's lifecycle,
when it might take a long time to load data or warm a cache, than during steady-state operation.
This cannot be updated.
More info: https://kubernetes.io/docs/concepts/workloads/pods/pod-lifecycle#container-probes |
false |
stdin | boolean |
Whether this container should allocate a buffer for stdin in the container runtime. If this
is not set, reads from stdin in the container will always result in EOF.
Default is false. |
false |
stdinOnce | boolean |
Whether the container runtime should close the stdin channel after it has been opened by
a single attach. When stdin is true the stdin stream will remain open across multiple attach
sessions. If stdinOnce is set to true, stdin is opened on container start, is empty until the
first client attaches to stdin, and then remains open and accepts data until the client disconnects,
at which time stdin is closed and remains closed until the container is restarted. If this
flag is false, a container processes that reads from stdin will never receive an EOF.
Default is false |
false |
terminationMessagePath | string |
Optional: Path at which the file to which the container's termination message
will be written is mounted into the container's filesystem.
Message written is intended to be brief final status, such as an assertion failure message.
Will be truncated by the node if greater than 4096 bytes. The total message length across
all containers will be limited to 12kb.
Defaults to /dev/termination-log.
Cannot be updated. |
false |
terminationMessagePolicy | string |
Indicate how the termination message should be populated. File will use the contents of
terminationMessagePath to populate the container status message on both success and failure.
FallbackToLogsOnError will use the last chunk of container log output if the termination
message file is empty and the container exited with an error.
The log output is limited to 2048 bytes or 80 lines, whichever is smaller.
Defaults to File.
Cannot be updated. |
false |
tty | boolean |
Whether this container should allocate a TTY for itself, also requires 'stdin' to be true.
Default is false. |
false |
volumeDevices | []object |
volumeDevices is the list of block devices to be used by the container. |
false |
volumeMounts | []object |
Pod volumes to mount into the container's filesystem.
Cannot be updated. |
false |
workingDir | string |
Container's working directory.
If not specified, the container runtime's default will be used, which
might be configured in the container image.
Cannot be updated. |
false |

Whether the container runtime should close the stdin channel after it has been opened by
a single attach. When stdin is true the stdin stream will remain open across multiple attach
sessions. If stdinOnce is set to true, stdin is opened on container start, is empty until the
first client attaches to stdin, and then remains open and accepts data until the client disconnects,

restartPolicy | string |
RestartPolicy defines the restart behavior of individual containers in a pod.
This field may only be set for init containers, and the only allowed value is "Always".
For non-init containers or when this field is not specified,
the restart behavior is defined by the Pod's restart policy and the container type.
Setting the RestartPolicy as "Always" for the init container will have the following effect:
this init container will be continually restarted on
exit until all regular containers have terminated. Once all regular
containers have completed, all init containers with restartPolicy "Always"
will be shut down. This lifecycle differs from normal init containers and
is often referred to as a "sidecar" container. Although this init
container still starts in the init container sequence, it does not wait
for the container to complete before proceeding to the next init
container. Instead, the next init container starts immediately after this
init container is started, or after any startupProbe has successfully
completed. |

startupProbe | object |
StartupProbe indicates that the Pod has successfully initialized.
If specified, no other probes are executed until this completes successfully.
If this probe fails, the Pod will be restarted, just as if the livenessProbe failed.
This can be used to provide different probe parameters at the beginning of a Pod's lifecycle,
when it might take a long time to load data or warm a cache, than during steady-state operation.
This cannot be updated.
More info: https://kubernetes.io/docs/concepts/workloads/pods/pod-lifecycle#container-probes |
false |
stdin | boolean |
Whether this container should allocate a buffer for stdin in the container runtime. If this
is not set, reads from stdin in the container will always result in EOF.
Default is false. |
false |
stdinOnce | boolean |
Whether the container runtime should close the stdin channel after it has been opened by
a single attach. When stdin is true the stdin stream will remain open across multiple attach
sessions. If stdinOnce is set to true, stdin is opened on container start, is empty until the
first client attaches to stdin, and then remains open and accepts data until the client disconnects,
at which time stdin is closed and remains closed until the container is restarted. If this
flag is false, a container processes that reads from stdin will never receive an EOF.
Default is false |
false |
terminationMessagePath | string |
Optional: Path at which the file to which the container's termination message
will be written is mounted into the container's filesystem.
Message written is intended to be brief final status, such as an assertion failure message.
Will be truncated by the node if greater than 4096 bytes. The total message length across
all containers will be limited to 12kb.
Defaults to /dev/termination-log.
Cannot be updated. |
false |
terminationMessagePolicy | string |
Indicate how the termination message should be populated. File will use the contents of
terminationMessagePath to populate the container status message on both success and failure.
FallbackToLogsOnError will use the last chunk of container log output if the termination
message file is empty and the container exited with an error.
The log output is limited to 2048 bytes or 80 lines, whichever is smaller.

CassandraDatacenter.spec.podTemplateSpec.spec.initContainers[index].lifecycle.preStop
PreStop is called immediately before a container is terminated due to an API request or management event such as liveness/startup probe failure, preemption, resource contention, etc. The handler is not called if the container crashes or exits. The Pod’s termination grace period countdown begins before the PreStop hook is executed. Regardless of the outcome of the handler, the container will eventually terminate within the Pod’s termination grace period (unless delayed by finalizers). Other management of the container blocks until the hook completes or until the termination grace period is reached.

Name | Type | Description | Required |
---|---|---|---|
effect | string |
Effect indicates the taint effect to match. Empty means match all taint effects.
When specified, allowed values are NoSchedule, PreferNoSchedule and NoExecute. |
false |
key | string |
Key is the taint key that the toleration applies to. Empty means match all taint keys.
If the key is empty, operator must be Exists; this combination means to match all values and all keys. |
false |
operator | string |
Operator represents a key's relationship to the value.
Valid operators are Exists and Equal. Defaults to Equal.
Exists is equivalent to wildcard for value, so that a pod can
tolerate all taints of a particular category. |
false |
tolerationSeconds | integer |
TolerationSeconds represents the period of time the toleration (which must be
of effect NoExecute, otherwise this field is ignored) tolerates the taint. By default,

false |
CassandraDatacenter.spec.podTemplateSpec.spec.topologySpreadConstraints[index]
TopologySpreadConstraint specifies how to spread matching pods among the given topology.
Name | Type | Description | Required |
---|---|---|---|
maxSkew | integer |
MaxSkew describes the degree to which pods may be unevenly distributed.
When `whenUnsatisfiable=DoNotSchedule`, it is the maximum permitted difference
between the number of matching pods in the target topology and the global minimum.
The global minimum is the minimum number of matching pods in an eligible domain
or zero if the number of eligible domains is less than MinDomains.
For example, in a 3-zone cluster, MaxSkew is set to 1, and pods with the same
labelSelector spread as 2/2/1:
In this case, the global minimum is 1.
| zone1 | zone2 | zone3 |
| P P | P P | P |
- if MaxSkew is 1, incoming pod can only be scheduled to zone3 to become 2/2/2;
scheduling it onto zone1(zone2) would make the ActualSkew(3-1) on zone1(zone2)
violate MaxSkew(1).
- if MaxSkew is 2, incoming pod can be scheduled onto any zone.
When `whenUnsatisfiable=ScheduleAnyway`, it is used to give higher precedence
to topologies that satisfy it.
It's a required field. Default value is 1 and 0 is not allowed. Format: int32 |
true |
topologyKey | string |
TopologyKey is the key of node labels. Nodes that have a label with this key
and identical values are considered to be in the same topology.
We consider each |
true |
whenUnsatisfiable | string |
WhenUnsatisfiable indicates how to deal with a pod if it doesn't satisfy
the spread constraint.
- DoNotSchedule (default) tells the scheduler not to schedule it.
- ScheduleAnyway tells the scheduler to schedule the pod in any location,
but giving higher precedence to topologies that would help reduce the
skew.
A constraint is considered "Unsatisfiable" for an incoming pod
if and only if every possible node assignment for that pod would violate
"MaxSkew" on some topology.
For example, in a 3-zone cluster, MaxSkew is set to 1, and pods with the same
labelSelector spread as 3/1/1:
| zone1 | zone2 | zone3 |
| P P P | P | P |
If WhenUnsatisfiable is set to DoNotSchedule, incoming pod can only be scheduled
to zone2(zone3) to become 3/2/1(3/1/2) as ActualSkew(2-1) on zone2(zone3) satisfies
MaxSkew(1). In other words, the cluster can still be imbalanced, but scheduler
won't make it *more* imbalanced.
It's a required field. |
true |
labelSelector | object |
LabelSelector is used to find matching pods.
Pods that match this label selector are counted to determine the number of pods
in their corresponding topology domain. |
false |
matchLabelKeys | []string |
MatchLabelKeys is a set of pod label keys to select the pods over which
spreading will be calculated. The keys are used to lookup values from the
incoming pod labels, those key-value labels are ANDed with labelSelector
to select the group of existing pods over which spreading will be calculated
for the incoming pod. The same key is forbidden to exist in both MatchLabelKeys and LabelSelector.
MatchLabelKeys cannot be set when LabelSelector isn't set.
Keys that don't exist in the incoming pod labels will
be ignored. A null or empty list means only match against labelSelector.
This is a beta field and requires the MatchLabelKeysInPodTopologySpread feature gate to be enabled (enabled by default). |
false |
minDomains | integer |
MinDomains indicates a minimum number of eligible domains.
When the number of eligible domains with matching topology keys is less than minDomains,
Pod Topology Spread treats “global minimum” as 0, and then the calculation of Skew is performed.
And when the number of eligible domains with matching topology keys equals or greater than minDomains,
this value has no effect on scheduling.
As a result, when the number of eligible domains is less than minDomains,
scheduler won’t schedule more than maxSkew Pods to those domains.
If value is nil, the constraint behaves as if MinDomains is equal to 1.
Valid values are integers greater than 0.
When value is not nil, WhenUnsatisfiable must be DoNotSchedule.
For example, in a 3-zone cluster, MaxSkew is set to 2, MinDomains is set to 5 and pods with the same labelSelector spread as 2/2/2: | zone1 | zone2 | zone3 | | P P | P P | P P | The number of domains is less than 5(MinDomains), so “global minimum” is treated as 0. In this situation, new pod with the same labelSelector cannot be scheduled, because computed skew will be 3(3 - 0) if new Pod is scheduled to any of the three zones, it will violate MaxSkew. This is a beta field and requires the MinDomainsInPodTopologySpread feature gate to be enabled (enabled by default). |
false |
nodeAffinityPolicy | string |

CassandraDatacenter.spec.podTemplateSpec.spec.volumes[index].ephemeral
ephemeral represents a volume that is handled by a cluster storage driver. The volume’s lifecycle is tied to the pod that defines it - it will be created before the pod starts, and deleted when the pod is removed.
Use this if: a) the volume is only needed while the pod runs, b) features of normal volumes like restoring from snapshot or capacity tracking are needed, c) the storage driver is specified through a storage class, and d) the storage driver supports dynamic volume provisioning through a PersistentVolumeClaim (see EphemeralVolumeSource for more information on the connection between this volume type and PersistentVolumeClaim).
Use PersistentVolumeClaim or one of the vendor-specific APIs for volumes that persist for longer than the lifecycle of an individual pod.
Use CSI for light-weight local ephemeral volumes if the CSI driver is meant to be used that way - see the documentation of the driver for more information.
A pod can use both types of ephemeral volumes and persistent volumes at the same time.
Name | Type | Description | Required |
---|---|---|---|
volumeClaimTemplate | object |

Starting the pod is then blocked until the unrelated PVC is removed. If such a pre-created PVC is meant to be used by the pod, the PVC has to updated with an owner reference to the pod once the pod exists. Normally this should not be necessary, but it may be useful when manually reconstructing a broken cluster. This field is read-only and no changes will be made by Kubernetes to the PVC after it has been created. Required, must not be nil. |

pod. The name of the PVC will be <pod name>-<volume name>
where
<volume name>
is the name from the PodSpec.Volumes
array
entry. Pod validation will reject the pod if the concatenated name
is not valid for a PVC (for example, too long).
An existing PVC with that name that is not owned by the pod will not be used for the pod to avoid using an unrelated volume by mistake. Starting the pod is then blocked until the unrelated PVC is removed. If such a pre-created PVC is meant to be used by the pod, the PVC has to updated with an owner reference to the pod once the pod exists.

dataSource | object |
dataSource field can be used to specify either:
* An existing VolumeSnapshot object (snapshot.storage.k8s.io/VolumeSnapshot)
* An existing PVC (PersistentVolumeClaim)
If the provisioner or an external controller can support the specified data source,
it will create a new volume based on the contents of the specified data source.
When the AnyVolumeDataSource feature gate is enabled, dataSource contents will be copied to dataSourceRef,
and dataSourceRef contents will be copied to dataSource when dataSourceRef.namespace is not specified.
If the namespace is specified, then dataSourceRef will not be copied to dataSource. |
false |
dataSourceRef | object |
dataSourceRef specifies the object from which to populate the volume with data, if a non-empty
volume is desired. This may be any object from a non-empty API group (non
core object) or a PersistentVolumeClaim object.
When this field is specified, volume binding will only succeed if the type of
the specified object matches some installed volume populator or dynamic
provisioner.
This field will replace the functionality of the dataSource field and as such
if both fields are non-empty, they must have the same value. For backwards
compatibility, when namespace isn't specified in dataSourceRef,
both fields (dataSource and dataSourceRef) will be set to the same
value automatically if one of them is empty and the other is non-empty.
When namespace is specified in dataSourceRef,
dataSource isn't set to the same value and must be empty.
There are three important differences between dataSource and dataSourceRef:
* While dataSource only allows two specific types of objects, dataSourceRef
allows any non-core object, as well as PersistentVolumeClaim objects.
* While dataSource ignores disallowed values (dropping them), dataSourceRef
preserves all values, and generates an error if a disallowed value is
specified.
* While dataSource only allows local objects, dataSourceRef allows objects
in any namespaces.
(Beta) Using this field requires the AnyVolumeDataSource feature gate to be enabled.
(Alpha) Using the namespace field of dataSourceRef requires the CrossNamespaceVolumeDataSource feature gate to be enabled. |

More info: https://kubernetes.io/docs/concepts/storage/persistent-volumes#class-1 |
false |
volumeAttributesClassName | string |
volumeAttributesClassName may be used to set the VolumeAttributesClass used by this claim.
If specified, the CSI driver will create or update the volume with the attributes defined
in the corresponding VolumeAttributesClass. This has a different purpose than storageClassName,
it can be changed after the claim is created. An empty string value means that no VolumeAttributesClass
will be applied to the claim but it's not allowed to reset this field to empty string once it is set.
If unspecified and the PersistentVolumeClaim is unbound, the default VolumeAttributesClass
will be set by the persistentvolume controller if it exists.
If the resource referred to by volumeAttributesClass does not exist, this PersistentVolumeClaim will be
set to a Pending state, as reflected by the modifyVolumeStatus field, until such as a resource
exists.

CassandraDatacenter.status.trackedTasks[index]
ObjectReference contains enough information to let you inspect or modify the referred object.
New uses of this type are discouraged because of difficulty describing its usage when embedded in APIs.
- Ignored fields. It includes many fields which are not generally honored. For instance, ResourceVersion and FieldPath are both very rarely valid in actual usage.
- Invalid usage help. It is impossible to add specific help for individual usage. In most embedded usages, there are particular restrictions like, “must refer only to types A and B” or “UID not honored” or “name must be restricted”. Those cannot be well described when embedded.
- Inconsistent validation. Because the usages are different, the validation rules are different by usage, which makes it hard for users to predict what will happen.
- The fields are both imprecise and overly precise. Kind is not a precise mapping to a URL. This can produce ambiguity during interpretation and require a REST mapping. In most cases, the dependency is on the group,resource tuple and the version of the actual struct is irrelevant.
- We cannot easily change it. Because this type is embedded in many locations, updates to this type will affect numerous schemas. Don’t make new APIs embed an underspecified API type they do not control.
Instead of using this type, create a locally provided and used type that is well-focused on your reference. For example, ServiceReferences for admission registration: https://github.com/kubernetes/api/blob/release-1.17/admissionregistration/v1/types.go#L533 .

For example, if the object reference is to a container within a pod, this would take on a value like:
"spec.containers{name}" (where "name" refers to the name of the container that triggered
the event) or if no container name is specified "spec.containers[2]" (container with
index 2 in this pod). This syntax is chosen only to have some well-defined way of
