false |
K8ssandraCluster.spec
K8ssandraClusterSpec defines the desired state of K8ssandraCluster
Name | Type | Description | Required |
---|---|---|---|
auth | boolean |
Whether to enable authentication in this cluster. The default is true; it is highly recommended to always leave authentication turned on. When enabled, authentication will be enforced not only on Cassandra nodes, but also on Reaper, Medusa and Stargate nodes, if any. Default: true |
false |
cassandra | object |
Cassandra is a specification of the Cassandra cluster. This includes everything from the number of datacenters, the k8s cluster where each DC should be deployed, node affinity (via racks), individual C* node settings, JVM settings, and more. |
false |
externalDatacenters | []string |
During a migration the operator should alter keyspaces replication settings including the following external DCs. This avoids removing replicas from datacenters which are outside of the operator scope (not referenced in the CR). Replication settings changes will only apply to system_* keyspaces as well as reaper_db and data_endpoint_auth (Stargate). |
false |
medusa | object |
Medusa defines the desired deployment characteristics for Medusa in this K8ssandraCluster. If this is non-nil, Medusa will be deployed in every Cassandra pod in this K8ssandraCluster. |
false |
reaper | object |
Reaper defines the desired deployment characteristics for Reaper in this K8ssandraCluster. If this is non-nil, Reaper will be deployed on every Cassandra datacenter in this K8ssandraCluster. |
false |
stargate | object |
Stargate defines the desired deployment characteristics for Stargate in this K8ssandraCluster. If this is non-nil, Stargate will be deployed on every Cassandra datacenter in this K8ssandraCluster. |
false |
K8ssandraCluster.spec.cassandra
Cassandra is a specification of the Cassandra cluster. This includes everything from the number of datacenters, the k8s cluster where each DC should be deployed, node affinity (via racks), individual C* node settings, JVM settings, and more.
Name | Type | Description | Required |
---|---|---|---|
additionalSeeds | []string |
AdditionalSeeds specifies Cassandra node IPs for an existing datacenter. This is primarily intended for migrations from an existing Cassandra cluster that is not managed by k8ssandra-operator. Note that this property should NOT be used to set seeds for a DC that is or will be managed by k8ssandra-operator. k8ssandra-operator already manages seeds for DCs that it manages. If you have DNS set up such that you can resolve hostnames for the remote Cassandra cluster, then you can specify hostnames here; otherwise, use IP addresses. |
false |
clientEncryptionStores | object |
Client encryption stores which are used by Cassandra and Reaper. |
false |
config | object |
CassandraConfig is configuration settings that are applied to cassandra.yaml and jvm-options for 3.11.x or jvm-server-options for 4.x. |
false |
datacenters | []object |
Datacenters a list of the DCs in the cluster. |
false |
jmxInitContainerImage | object |
The image to use in each Cassandra pod for the (short-lived) init container that enables JMX remote authentication on Cassandra pods. This is only useful when authentication is enabled in the cluster. The default is "busybox:1.34.1". Default: map[name:busybox tag:1.34.1] |
false |
mgmtAPIHeap | int or string |
MgmtAPIHeap defines the amount of memory devoted to the management api heap. |
false |
networking | object |
Networking enables host networking and configures a NodePort ports. |
false |
racks | []object |

false |
resources | object |
Resources is the cpu and memory resources for the cassandra container. |
false |
serverEncryptionStores | object |
Internode encryption stores which are used by Cassandra and Stargate. |
false |
serverImage | string |
ServerImage is the image for the cassandra container. Note that this should be a management-api image. If left empty the operator will choose a default image based on ServerVersion. |
false |
serverVersion | string |
ServerVersion is the Cassandra version. |
false |
softPodAntiAffinity | boolean |
SoftPodAntiAffinity sets whether multiple Cassandra instances can be scheduled on the same node. This should normally be false to ensure cluster resilience but may be set true for test/dev scenarios to minimise the number of nodes required. |
false |
storageConfig | object |
StorageConfig is the persistent storage requirements for each Cassandra pod. This includes everything under /var/lib/cassandra, namely the commit log and data directories. |
false |
superuserSecretRef | object |
The reference to the superuser secret to use for Cassandra. If unspecified, a default secret will be generated with a random password; the generated secret name will be " |
false |
telemetry | object |
Telemetry defines the desired state for telemetry resources in this K8ssandraCluster. If telemetry configurations are defined, telemetry resources will be deployed to integrate with a user-provided monitoring solution (at present, only support for Prometheus is available). |

stargate | object |
Stargate defines the desired deployment characteristics for Stargate in this datacenter. Leave nil to skip deploying Stargate in this datacenter. |
false |
stopped | boolean |
Stopped means that the datacenter will be stopped. Use this for maintenance or for cost saving. 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. Default: false |
false |
storageConfig | object |
StorageConfig is the persistent storage requirements for each Cassandra pod. This includes everything under /var/lib/cassandra, namely the commit log and data directories. |
false |

Specifies the object from which to populate the volume with data, if a non-empty volume is desired. This may be any local 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, 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. There are two 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. (Alpha) Using this field requires the AnyVolumeDataSource feature gate to be enabled. |

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. 1. Ignored fields. It includes many fields which are not generally honored. For instance, ResourceVersion and FieldPath are both very rarely valid in actual usage. 2. 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. 3. 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. 4. 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. 5. 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 referencing a part of an object. TODO: this design is not final and this field is subject to change in the future. |

dataSource | object |
This 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.

dataSourceRef | object |
Specifies the object from which to populate the volume with data, if a non-empty volume is desired. This may be any local 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, 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. There are two 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.

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 |

false |
ports | []object |
List of ports to expose from the container. Exposing a port here gives the system additional information about the network connections a container uses, but is primarily informational. Not specifying a port here DOES NOT prevent that port from being exposed. Any port which is listening on the default "0.0.0.0" address inside a container will be accessible from the network. Cannot be updated. |
false |
readinessProbe | object |
Periodic probe of container service readiness. Container will be removed from service endpoints if the probe fails. Cannot be updated. More info: https://kubernetes.io/docs/concepts/workloads/pods/pod-lifecycle#container-probes |

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 |

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. |

The scheduler will prefer to schedule pods to nodes that satisfy the anti-affinity expressions specified by this field, but it may choose a node that violates one or more of the expressions. The node that is most preferred is the one with the greatest sum of weights, i.e. for each node that meets all of the scheduling requirements (resource request, requiredDuringScheduling anti-affinity expressions, etc.), compute a sum by iterating through the elements of this field and adding "weight" to the sum if the node has pods which matches the corresponding podAffinityTerm; the node(s) with the highest sum are the most preferred. |
false |
requiredDuringSchedulingIgnoredDuringExecution | []object |
If the anti-affinity requirements specified by this field are not met at scheduling time, the pod will not be scheduled onto the node. If the anti-affinity requirements specified by this field cease to be met at some point during pod execution (e.g. due to a pod label update), the system may or may not try to eventually evict the pod from its node. When there are multiple elements, the lists of nodes corresponding to each podAffinityTerm are intersected, i.e. all terms must be satisfied. |

An EphemeralContainer is a container that may be added temporarily to an existing pod for user-initiated activities such as debugging. Ephemeral containers have no resource or scheduling guarantees, and they will not be restarted when they exit or when a pod is removed or restarted. If an ephemeral container causes a pod to exceed its resource allocation, the pod may be evicted. Ephemeral containers may not be added by directly updating the pod spec. They must be added via the pod’s ephemeralcontainers subresource, and they will appear in the pod spec once added. This is an alpha feature enabled by the EphemeralContainers feature flag.

If this flag is false, a container processes that reads from stdin will never receive an EOF. Default is false |
false |
targetContainerName | string |
If set, the name of the container from PodSpec that this ephemeral container targets. The ephemeral container will be run in the namespaces (IPC, PID, etc) of this container.

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.

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. For example, in a 3-zone cluster, MaxSkew is set to 1, and pods with the same labelSelector spread as 1/1/0: | zone1 | zone2 | zone3 | | P | P | | - if MaxSkew is 1, incoming pod can only be scheduled to zone3 to become 1/1/1; scheduling it onto zone1(zone2) would make the ActualSkew(2-0) 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 assigment 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. |

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.

CassandraBackup.status.cassdcTemplateSpec.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. This is a beta feature and only available when the GenericEphemeralVolume feature gate is enabled.
Name | Type | Description | Required |
---|---|---|---|
volumeClaimTemplate | object |
Will be used to create a stand-alone PVC to provision the volume. The pod in which this EphemeralVolumeSource is embedded will be the owner of the PVC, i.e. the PVC will be deleted together with the pod. The name of the PVC will be ` |
false |
CassandraBackup.status.cassdcTemplateSpec.spec.podTemplateSpec.spec.volumes[index].ephemeral.volumeClaimTemplate
Will be used to create a stand-alone PVC to provision the volume. The pod in which this EphemeralVolumeSource is embedded will be the owner of the PVC, i.e. the PVC will be deleted together with the 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. 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.
Name | Type | Description | Required |
---|---|---|---|
spec | object |
The specification for the PersistentVolumeClaim. The entire content is copied unchanged into the PVC that gets created from this template. The same fields as in a PersistentVolumeClaim are also valid here. |
true |
metadata | object |

false |
CassandraBackup.status.cassdcTemplateSpec.spec.podTemplateSpec.spec.volumes[index].ephemeral.volumeClaimTemplate.spec
The specification for the PersistentVolumeClaim. The entire content is copied unchanged into the PVC that gets created from this template. The same fields as in a PersistentVolumeClaim are also valid here.

---|---|---|---|
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 |
This 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. If the AnyVolumeDataSource feature gate is enabled, this field will always have the same contents as the DataSourceRef field. |
false |
dataSourceRef | object |
Specifies the object from which to populate the volume with data, if a non-empty volume is desired. This may be any local 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, 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. There are two 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. (Alpha) Using this field requires the AnyVolumeDataSource feature gate to be enabled. |
