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

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

Example: containers: - name: server-system-logger - name: custom-container image: busybox - name: cassandra	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
datacenters	[]object	Datacenters a list of the DCs in the cluster.	false
dseWorkloads	object		false
extraVolumes	object	Volumes defines additional volumes to be added to each Cassandra pod. If the volume uses a PersistentVolumeClaim, the PVC will be managed by the statefulset.	false
initContainers	[]object	InitContainers defines init-containers to be deployed in each Cassandra pod. K8ssandra-operator and cass-operator will create their own init-containers, which can be referenced here to control ordering or override specific settings such as mounts or resources request/limits for example. Only the name of the k8ssandra-operator/cass-operator init-containers is required, not their full definition which will be created by the operators. Example: initContainers: - name: server-config-init - name: custom-init-container image: busybox - name: medusa-restore Otherwise init-containers referenced here will be injected in first position	false
jmxInitContainerImage	object	Deprecated: JMX security is now based on CQL roles. We don't need an init container to configure JMX authentication anymore. The value of this field will be ignored.	false

perNodeConfigInitContainerImage	string	The image to use in each Cassandra pod for the (short-lived) init container that merges global and perNodeConfig configuration. This is only useful when PerNodeConfigMapRef is set. The default is "mikefarah/yq:4". Default: mikefarah/yq:4	false
podSecurityContext	object	PodSecurityContext defines the security context for the Cassandra pods.	false
racks	[]object	Racks is a list of named racks. Note that racks are used to create node affinity. //	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 or DSE version. The following versions are supported: - Cassandra: 3.11.X, 4.X.X and 5.X.X - DSE: 6.8.X, 7.x.x	false
serviceAccount	string	The k8s service account to use for the Cassandra pods	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 "-superuser" where is the K8ssandraCluster CRD name.	false
telemetry	object	Telemetry defines the desired state for telemetry resources in this datacenter. 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).	false

^{^{↩ Parent}}

A single application container that you want to run within a pod.

Name	Type	Description	Required
name	string	Name of the container specified as a DNS_LABEL. Each container in a pod must have a unique name (DNS_LABEL). Cannot be updated.	true
args	[]string	Arguments to the entrypoint. The container image's CMD is used if this is not provided. Variable references $(VAR_NAME) are expanded using the container's environment. If a variable cannot be resolved, the reference in the input string will be unchanged. Double $$ are reduced to a single $, which allows for escaping the $(VAR_NAME) syntax: i.e. "$$(VAR_NAME)" will produce the string literal "$(VAR_NAME)". Escaped references will never be expanded, regardless of whether the variable exists or not. Cannot be updated. More info: https://kubernetes.io/docs/tasks/inject-data-application/define-command-argument-container/#running-a-command-in-a-shell	false
command	[]string	Entrypoint array. Not executed within a shell. The container image's ENTRYPOINT is used if this is not provided. Variable references $(VAR_NAME) are expanded using the container's environment. If a variable cannot be resolved, the reference in the input string will be unchanged. Double $$ are reduced to a single $, which allows for escaping the $(VAR_NAME) syntax: i.e. "$$(VAR_NAME)" will produce the string literal "$(VAR_NAME)". Escaped references will never be expanded, regardless of whether the variable exists or not. Cannot be updated. More info: https://kubernetes.io/docs/tasks/inject-data-application/define-command-argument-container/#running-a-command-in-a-shell	false
env	[]object	List of environment variables to set in the container. Cannot be updated.	false
envFrom	[]object	List of sources to populate environment variables in the container. The keys defined within a source must be a C_IDENTIFIER. All invalid keys will be reported as an event when the container is starting. When a key exists in multiple sources, the value associated with the last source will take precedence. Values defined by an Env with a duplicate key will take precedence. Cannot be updated.	false
image	string	Container image name. More info: https://kubernetes.io/docs/concepts/containers/images This field is optional to allow higher level config management to default or override container images in workload controllers like Deployments and StatefulSets.	false
imagePullPolicy	string	Image pull policy. One of Always, Never, IfNotPresent. Defaults to Always if :latest tag is specified, or IfNotPresent otherwise. Cannot be updated. More info: https://kubernetes.io/docs/concepts/containers/images#updating-images	false
lifecycle	object	Actions that the management system should take in response to container lifecycle events. Cannot be updated.	false
livenessProbe	object	Periodic probe of container liveness. Container will be restarted if the probe fails. Cannot be updated. More info: https://kubernetes.io/docs/concepts/workloads/pods/pod-lifecycle#container-probes	false
ports	[]object	List of ports to expose from the container. 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. Modifying this array with strategic merge patch may corrupt the data. For more information See https://github.com/kubernetes/kubernetes/issues/108255. 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

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

K8ssandraCluster.spec.cassandra.containers[index].lifecycle.preStop

^{^{↩ Parent}}

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.

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

The ConfigMap is expected to have entries in the following form: _.yaml, where is the name of the pod and is the name of a configuration file (typically, cassandra.yaml). The value of the entry is expected to be a YAML fragment that contains the per-node configuration for each pod. When the pod is started, the per-node ConfigMap is mounted and the contents of each entry corresponding to the pod are merged into their respective configuration files.	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
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

args	[]string	Arguments to the entrypoint. The container image's CMD is used if this is not provided. Variable references $(VAR_NAME) are expanded using the container's environment. If a variable cannot be resolved, the reference in the input string will be unchanged. Double $$ are reduced to a single $, which allows for escaping the $(VAR_NAME) syntax: i.e. "$$(VAR_NAME)" will produce the string literal "$(VAR_NAME)". Escaped references will never be expanded, regardless of whether the variable exists or not. Cannot be updated. More info: https://kubernetes.io/docs/tasks/inject-data-application/define-command-argument-container/#running-a-command-in-a-shell	false

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.

K8ssandraCluster.spec.cassandra.datacenters[index].extraVolumes.pvcs[index].volumeSource.ephemeral

^{^{↩ Parent}}

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.

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.

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.	false

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.

K8ssandraCluster.spec.cassandra.datacenters[index].extraVolumes.volumes[index].ephemeral

^{^{↩ Parent}}

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	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 `-` where `` 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.	false

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

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	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 `-` where `` 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.
