Values
| Key | Type | Default | Description |
|---|---|---|---|
| cassandra.enabled | bool | true |
Enables installation of Cassandra cluster. Set to false if you only wish to install operators. |
| cassandra.version | string | "4.0.1" |
The Cassandra version to use. The supported versions include the following: - 3.11.7 - 3.11.8 - 3.11.9 - 3.11.10 - 3.11.11 - 4.0.0 - 4.0.1 |
| cassandra.versionImageMap | object | {"3.11.10":"k8ssandra/cass-management-api:3.11.10-v0.1.27","3.11.11":"k8ssandra/cass-management-api:3.11.11-v0.1.33","3.11.7":"k8ssandra/cass-management-api:3.11.7-v0.1.33","3.11.8":"k8ssandra/cass-management-api:3.11.8-v0.1.33","3.11.9":"k8ssandra/cass-management-api:3.11.9-v0.1.27","4.0.0":"k8ssandra/cass-management-api:4.0.0-v0.1.33","4.0.1":"k8ssandra/cass-management-api:4.0.1-v0.1.33"} |
Specifies the image to use for a particular Cassandra version. Exercise care and caution with changing these values! cass-operator is not designed to work with arbitrary Cassandra images. It expects the cassandra container to be running management-api images. If you do want to change one of these mappings, the new value should be a management-api image. |
| cassandra.image | object | {} |
Overrides the default image mappings. This is intended for advanced use cases like development or testing. By default the Cassandra version has to be one that is in versionImageMap. Template rendering will fail if the version is not in the map. When you set the image directly, the version mapping check is skipped. Note that you are still constrained to the versions supported by cass-operator. |

| cassandra.auth | object | {"cacheUpdateIntervalMillis":3600000,"cacheValidityPeriodMillis":3600000,"enabled":true,"superuser":{"secret":"","username":""}} |
Authentication and authorization related settings. |
| cassandra.auth.enabled | bool | true |
Enables or disables authentication and authorization. This also enables/disables JMX authentication. Note that if Reaper is enabled JMX authentication will still be enabled even if auth is disabled here. This is because Reaper requires remote JMX access. |
| cassandra.auth.superuser | object | {"secret":"","username":""} |
Configures the default Cassandra superuser when authentication is enabled. If neither superuser.secret nor superuser.username are set, then a user and a secret with the user’s credentials will be created.

If superuser.secret is set, then the Cassandra user will be created from the contents of the secret. If superuser.secret is not set and if superuser.username is set, a secret will be generated using the specified username. The password will be generated as previously described. JMX credentials will also be created for the superuser. The same username/password that is used here will be used for JMX. If you change the Cassandra superuser credentials through cqlsh for example, the JMX credentials will not be updated. You need to update the credentials via helm upgrade in order for the change to propagate to JMX. This will be fixed in https://github.com/k8ssandra/k8ssandra/issues/323. |

| cassandra.cassandraLibDirVolume.size | string | "5Gi" |
Size of the provisioned persistent volume per node. It is recommended to keep the total amount of data per node to approximately 1 TB. With room for compactions this value should max out at ~2 TB. This recommendation is highly dependent on data model and compaction strategies in use. Consider testing with your data model to find an optimal value for your usecase. |
| cassandra.cassandraYamlConfigMap | string | nil |
Specifies the name of a ConfigMap that contains a custom cassandra.yaml. The ConfigMap should have a key named cassandra.yaml. The values will be merged with the base configuration.

| cassandra.additionalServiceConfig | object | {} |
Optional 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/” |
| cassandra.loggingSidecar.enabled | bool | true |
Set to false if you do not want to deploy the server-system-logger container. |

| cassandra.datacenters[0].racks | list | [{"affinityLabels":{},"name":"default"}] |
The replication factor for keyspaces in the datacenter. Triggers the even token distribution algorithm for num_tokens and the replication factor. Note that this property is for Cassandra 4.0 and later. Setting this property with Cassandra 3.11.x will result in a chart validation error. When the Cassandra version is 4.0, this property is enabled by default with a value of 3. allocateTokensForLocalRF: 3 – Specifies the racks for the data center, if unset the datacenter will be composed of a single rack named default. The number of racks should equal the replication factor of your application keyspaces. Cassandra will ensure that replicas are spread across racks versus having multiple replicas within the same rack. For example, let’s say we are using RF = 3 with a 9 node cluster and 3 racks (and 3 nodes per rack). There will be one replica of the dataset spread across each rack. |
| cassandra.datacenters[0].racks[0].name | string | "default" |
Identifier for the rack, this may align with the labels used to control where resources are deployed for this rack. For example, if a rack is limited to a single availability zone the identifier may be the name of that AZ (eg us-east-1a). |

an optional set of labels that are used to pin Cassandra pods to specific k8s worker nodes via affinity rules. See https://kubernetes.io/docs/tasks/configure-pod-container/assign-pods-nodes-using-node-affinity/ for background on using affinity rules. topology.kubernetes.io/zone is a well-known k8s label used by cloud providers to indicate the failure zone in which a k8s worker node is running. The following example illustrates how you can pin racks to specific failure zones. racks: - name: r1 affinityLabels: topology.kubernetes.io/zone: us-east1-b - name: r2 affinityLabels: topology.kubernetes.io/zone: us-east1-a - name: r3 affinityLabels: topology.kubernetes.io/zone: us-east1-c |

| medusa.cassandraUser | object | {"secret":"","username":""} |
Configures the Cassandra user used by Medusa when authentication is enabled. If neither cassandraUser.secret nor cassandraUser.username are set, then a Cassandra user and a secret will be created. The username will be medusa. The secret name will be of the form {clusterName}-medusa. The password will be a random 20 character password. If cassandraUser.secret is set, then the Cassandra user will be created from the contents of the secret. If cassandraUser.secret is not set and if cassandraUser.username is set, a secret will be generated using the specified username. The password will be generated as previously described. |
| medusa.multiTenant | bool | false |
Enables usage of a bucket across multiple clusters. |
| medusa.storage | string | "s3" |
API interface used by the object store. Supported values include s3, ‘s3_compatible’, google_storage and ‘azure_blobs’. For file system storage, i.e., a pod volume mount, use ‘local’ and set the podStorage properties. Note that ‘local’ does not necessarily imply a local volume. It could also be network attached storage. It is simply accessed through the file system. |
| medusa.storage_properties | object | {} |
Optional properties for storage. Supported values depend on the type of the storage. |
| medusa.bucketName | string | "awstest" |
|
| medusa.storageSecret | string | "medusa-bucket-key" |

| monitoring.grafana.provision_dashboards | bool | true |
Enables the creation of configmaps containing Grafana dashboards. If leveraging the kube-prometheus-stack subchart this value should be true. See https://helm.sh/docs/chart_template_guide/subcharts_and_globals/ for background on subcharts. |
| monitoring.prometheus.provision_service_monitors | bool | true |
Enables the creation of Prometheus Operator ServiceMonitor custom resources. If you are not using the kube-prometheus-stack subchart or do not have the ServiceMonitor CRD installed on your cluster, set this value to false. |
| monitoring.serviceMonitors.namespace | string | nil |
|
| cleaner | object | {"image":{"pullPolicy":"IfNotPresent","registry":"docker.io","repository":"k8ssandra/k8ssandra-tools","tag":"latest"}} |
The cleaner is a pre-delete hook that that ensures objects with finalizers get deleted. For example, cass-operator sets a finalizer on the CassandraDatacenter. Kubernetes blocks deletion of an object until all of its finalizers are cleared. In the case of the CassandraDatacenter object, cass-operator removes the finalizer. The problem is that there are no ordering guarantees with helm uninstall which means that the cass-operator deployment could be deleted before the CassandraDatacenter. The cleaner ensures that the CassandraDatacenter is deleted before cass-operator. |
