annotations

Determines if the operator restarts the Vertica process when the process is not running.

Set this parameter to false when performing manual maintenance that requires a DOWN database. This prevents the operator from interfering with the database state.

Default: true

A list of Secrets for custom TLS certificates.

Each certificate is mounted in the container at /certs/cert-name/key. For example, a PEM-encoded CA bundle named root_cert.pem and concealed in a Secret named aws-cert is mounted in /certs/aws-cert/root_cert.pem.

If you update the certificate after you add it to a custom resource, the operator updates the value automatically. If you add or delete a certificate, the operator reschedules the pod with the new configuration.

For implementation details, see Creating a Custom Resource.

The mount path in the container filesystem to a CA certificate file that validates HTTPS connections to a communal storage endpoint.

Typically, the certificate is stored in a Secret and included in certSecrets. For details, see Creating a Custom Resource.

The name of the Secret that stores the credentials for the communal storage endpoint.

For implementation details for each supported communal storage location, see Configuring Communal Storage.

A communal storage endpoint URL. The endpoint must begin with either the http:// or https:// protocol. For example:

https://path/to/endpoint

You cannot change this value after you create the custom resource instance.

This setting is required when initPolicy is set to Create or Revive.

When set to true, the operator includes in the path the unique identifier (UID) that Kubernetes assigns to the VerticaDB object. Including the UID creates a unique database path so that you can reuse the communal path in the same endpoint.

Default: false

The path to the communal storage bucket. For example:

s3://bucket-name/key-name

You must create this bucket before you create the Vertica database.

The following initPolicy values determine how to set this value:

• Create: The path must be empty.
• Revive: The path cannot be empty.

You cannot change this value after you create the custom resource.

The geographic location where the communal storage resources are located.

If you do not set the correct region, the configuration fails. You might experience a delay because Vertica retries several times before failing.

This setting is valid for Amazon Web Services (AWS) and Google Cloud Platform (GCP) only. Vertica ignores this setting for other communal storage providers.

Default:

• AWS: us-east-1
• GCP: US-EAST1

The database name. When initPolicy is set to Revive or ScheduleOnly, this must match the name of the source database.

Default: vertdb

Ignore the cluster lease when executing a revive or start_db.

Default: false

The image that defines the Vertica server container's runtime environment. If the container is hosted in a private container repository, this name must include the path to the repository.

When you update the image, the operator stops and restarts the cluster.

Default: vertica/vertica-k8s:latest

Determines how often Kubernetes pulls the image for an object. For details, see Updating Images in the Kubernetes documentation.

Default: If the image tag is latest, the default is Always. Otherwise, the default is IfNotPresent.

How to initialize the Vertica database in Kubernetes. Enter Create or Revive:

• Create forces the creation of a new database for the custom resource.
• Revive initializes an existing Eon Mode database as a StatefulSet with the revive command. For information about Revive, see Generating a Custom Resource from an Existing Eon Mode Database.
• ScheduleOnly schedules a subcluster for a Hybrid Kubernetes cluster.

The Secret that stores the following values for Kerberos authentication to Hadoop Distributed File System (HDFS):

• krb5.conf: Contains Kerberos configuration information.
• krb5.keytab: Contains credentials for the Vertica Kerberos principal. This file must be readable by the file owner that is running the process.

The default location for each of these files is the /etc directory.

Sets the fault tolerance for the cluster. The operator supports setting this value to 0 or 1 only. For details, see K-Safety.

You cannot change this value after you create the custom resource.

Default: 1

The Secret that contains the contents of license files. The Secret must share a namespace with the custom resource (CR). Each of the keys in the Secret is mounted as a file in /home/dbadmin/licensing/mnt.

If this value is set when the CR is created, the operator installs one of the licenses automatically, choosing the first one alphabetically.

If you update this value after you create the custom resource, you must manually install the Secret in each Vertica pod.

The path in the container filesystem for the local data, such as the catalog.

If initPolicy is set to Revive or ScheduleOnly, the dataPath for the new database must match the dataPath for the source database.

Default: /data

The path in the container filesystem that stores the depot.

If initPolicy is set to Revive or ScheduleOnly, the depotPath for the new database must match the depotPath for the source database.

Default: /depot

The minimum size of the local data volume when selecting a persistent volume (PV).

Default: 500 Gi

The name of the StorageClass used for the local data volume that stores the local catalog, depot, and configuration files. Select this value when defining the persistent volume claim (PVC).

By default, this parameter is not set. The PVC in the default configuration uses the default storage class set by Kubernetes.

The order of nodes during a revive operation. Each entry contains the subcluster index, and the number of pods to include from the subcluster.

For example, consider a database with the following setup:

- v_db_node0001: subcluster A
- v_db_node0002: subcluster A
- v_db_node0003: subcluster B
- v_db_node0004: subcluster A
- v_db_node0005: subcluster B
- v_db_node0006: subcluster B

If the subclusters[] list is defined as {'A', 'B'}, the revive order is as follows:

- {subclusterIndex:0, podCount:2} # 2 pods from subcluster A
- {subclusterIndex:1, podCount:1} # 1 pod from subcluster B
- {subclusterIndex:0, podCount:1} # 1 pod from subcluster A
- {subclusterIndex:1, podCount:2} # 2 pods from subcluster B

This parameter is used only when initPolicy is set to Revive.

When restarting pods, the number of seconds before admintools times out.

Default: 0. The operator uses the 20 minutes default used by admintools.

The number of shards in the database. You cannot update this value after you create the custom resource.

For more information about database shards and Eon Mode, see Configuring Your Vertica Cluster for Eon Mode.

One or more optional utility containers that complete tasks for the Vertica server container. Each sidecar entry is a fully-formed container spec, similar to the container that you add to a Pod spec.

The following example adds a sidecar named vlogger to the custom resource:

spec:
  ...
  sidecars:
    - name: vlogger
      image: vertica/vertica-logger:1.0.0
      volumeMounts:
        - name: my-custom-vol
          mountPath: /path/to/custom-volume

volumeMounts.name is the name of a custom volume. This value must match volumes.name to mount the custom volume in the sidecar container filesystem. See volumes for additional details.

For implementation details, see Creating a Custom Resource.

List of custom volumes and mount paths that persist sidecar container data. Each volume element requires a name value and a mountPath.

To mount a volume in the Vertica sidecar container filesystem, volumeMounts.name must match the volumes.name value for the corresponding sidecar definition, or the webhook returns an error.

For implementation details, see Creating a Custom Resource.

List of custom volumes that persist sidecar container data. Each volume element requires a name value and a volume type. volumes accepts any Kubernetes volume type.

To mount a volume in a sidecar filesystem, volumes.name must match the volumeMounts.name value for the corresponding sidecar element volume mount, or the webhook returns an error.

For implementation details, see Creating a Custom Resource.

A Secret that contains SSH credentials for authentication between an Eon Mode database and custom resource in a hybrid architecture.

The Secret requires the following values:

• id_rsa
• id_rsa.pub
• authorized_keys

For details, see Hybrid Kubernetes Clusters.

Applies rules that constrain the Vertica server pod to specific nodes. It is more expressive than nodeSelector. If this parameter is not set, then the pods use no affinity setting.

In production settings, it is a best practice to configure affinity to run one server pod per host node. For configuration details, see Creating a Custom Resource.

Indicates whether the subcluster is primary or secondary. Each database must have at least one primary subcluster.

Default: true

The subcluster name. This is a required setting. If you change the name of an existing subcluster, the operator deletes the old subcluster and creates a new one with the new name.

When subclusters[i].serviceType is set to NodePort, this parameter enables you to define the port that is opened at each node for external client connections. The port must be within the defined range allocated by the control plane (ports 30000-32767).

If you do not manually define a port number, Kubernetes chooses the port automatically.

Provides control over which nodes are used to schedule each pod. If this is not set, the node selector is left off the pod when it is created. To set this parameter, provide a list of key/value pairs.

The following example schedules server pods only at nodes that have the disktype=ssd and region=us-east labels:

subclusters:
  - name: defaultsubcluster
    nodeSelector:
      disktype: ssd
      region: us-east

The resource limits for pods in the StatefulSet, which sets the maximum amount of CPU and memory that each server pod can consume.

Vertica recommends that you set these values equal to subclusters[i].resources.requests to ensure that the pods are assigned to the guaranteed QoS class. This reduces the possibility that pods are chosen by the out of memory (OOM) Killer.

For more information, see Recommendations for Sizing Vertica Nodes and Clusters in the Vertica Knowledge Base.

Identifies the type of Kubernetes service to use for external client connectivity. The default is type is ClusterIP, which sets a stable IP and port that is accessible only from within Kubernetes itself.

Depending on the service type, you might need to set nodePort or externalIPs in addition to this configuration parameter.

Default: ClusterIP

The number of pods in the subcluster. This determines the number of Vertica nodes in the subcluster. Changing this number deletes or schedules new pods.

The minimum size of a subcluster is 1. The subclusters kSafety setting determines the minimum and maximum size of the cluster.

The Secret that contains the database superuser password. Create this Secret before deployment.

If you do not create this Secret before deployment, there is no password authentication for the database.

The Secret must use a key named password:

kubectl create secret generic su-passwd --from-literal=password=secret-password

The following text adds this Secret to the custom resource:

db:
  superuserSecretPassword: su-passwd

List of custom volumes and mount paths that persist Vertica server container data. Each volume element requires a name value and a mountPath.

To mount a volume in the Vertica server container filesystem, volumeMounts.name must match the volumes.name value defined in the spec definition, or the webhook returns an error.
