Custom Resource options

The operator is configured via the spec section of the deploy/cr.yaml file.

The metadata part of this file contains the following keys:

  • name (my-cluster-name by default) sets the name of your Percona Server for MongoDB Cluster; it should include only URL-compatible characters, not exceed 22 characters, start with an alphabetic character, and end with an alphanumeric character;

  • finalizers.delete-psmdb-pvc, if present, activates the Finalizer which deletes appropriate Persistent Volume Claims after the cluster deletion event (off by default).

The spec part of the deploy/cr.yaml file contains the following sections:

Key Value type Default Description
platform string kubernetes Override/set the Kubernetes platform: kubernetes or openshift
pause boolean false Pause/resume: setting it to true gracefully stops the cluster, and setting it to false after shut down starts the cluster back.
unmanaged boolean false Unmanaged site in cross-site replication: setting it to true forces the Operator to run the cluster in unmanaged state - nodes do not form replica sets, operator does not control TLS certificates
crVersion string 1.13.0 Version of the Operator the Custom Resource belongs to
image string percona/percona-server-mongodb:4.4.16-16 The Docker image of Percona Server for MongoDB to deploy (actual image names can be found in the list of certified images)
imagePullPolicy string Always The policy used to update images
tls.certValidityDuration string 2160h The validity duration of the external certificate for cert manager (90 days by default). This value is used only at cluster creation time and can’t be changed for existing clusters
imagePullSecrets.name string private-registry-credentials The Kubernetes ImagePullSecret to access the custom registry
ClusterServiceDNSSuffix string svc.cluster.local The (non-standard) cluster domain to be used as a suffix of the Service name
clusterServiceDNSMode string Internal Can be either internal (exposed MongoDB instances will use ClusterIP addresses) or ServiceMesh (turns on for the exposed Services). Being set, ServiceMesh value suprecedes multiCluster settings, and therefore these two modes cannot be combined together.
allowUnsafeConfigurations boolean false Prevents users from configuring a cluster with unsafe parameters: starting it with less than 3 replica set instances, with an even number of replica set instances without additional arbiter, or without TLS/SSL certificates, or running a sharded cluster with less than 3 config server Pods or less than 2 mongos Pods (if false, the Operator will automatically change unsafe parameters to safe defaults)
updateStrategy string SmartUpdate A strategy the Operator uses for upgrades. Possible values are SmartUpdate, RollingUpdate and OnDelete
multiCluster.enabled boolean false Multi-cluster Services (MCS): setting it to true enables MCS cluster mode
multiCluster.DNSSuffix string svc.clusterset.local The cluster domain to be used as a suffix for multi-cluster Services used by Kubernetes (svc.clusterset.local by default)

Never or Disabled will completely disable automatic upgrades, otherwise it can be set to Latest or Recommended or to a specific version string of Percona Server for MongoDB (e.g. 5.0.11-10) that is wished to be version-locked (so that the user can control the version running, but use automatic upgrades to move between them)
