Custom Resource options¶

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

`metadata`¶

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-pods-in-order if present, activates the Finalizer which controls the proper Pods deletion order in case of the cluster deletion event (on by default)
finalizers.delete-psmdb-pvc if present, activates the Finalizer which deletes appropriate Persistent Volume Claims after the cluster deletion event (off by default)

Toplevel `spec` elements¶

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

`platform`¶

Override/set the Kubernetes platform: kubernetes or openshift.

Value type	Example
string	`kubernetes`

`pause`¶

Pause/resume: setting it to true gracefully stops the cluster, and setting it to false after shut down starts the cluster back.

Value type	Example
boolean	`false`

`unmanaged`¶

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.

Value type	Example
boolean	`false`

`crVersion`¶

Version of the Operator the Custom Resource belongs to.

Value type	Example
string	`1.16.2`

`image`¶

The Docker image of Percona Server for MongoDB to deploy (actual image names can be found in the list of certified images).

Value type	Example
string	`percona/percona`-`server`-`mongodb:6.0.15-12`

The policy used to update images .

Value type	Example
string	`Always`

`imagePullSecrets.name`¶

The Kubernetes ImagePullSecret to access the custom registry.

Value type	Example
string	`private`-`registry`-`credentials`

`initImage`¶

An alternative image for the initial Operator installation.

Value type	Example

`ClusterServiceDNSSuffix`¶

The (non-standard) cluster domain to be used as a suffix of the Service name.

Value type	Example
string	`svc.cluster.local`

`clusterServiceDNSMode`¶

Can be internal (local fully-qualified domain names will be used in replset configuration even if the replset is exposed - the default value), external (exposed MongoDB instances will use ClusterIP addresses, should be applied with caution) or ServiceMesh (turned on for the exposed Services). Being set, ServiceMesh value suprecedes multiCluster settings, and therefore these two modes cannot be combined together.

Value type	Example
string	`Internal`

`allowUnsafeConfigurations`¶

After switching to unsafe configurations permissive mode you will not be able to switch the cluster back by setting spec.allowUnsafeConfigurations key to false, the flag will be ignored. This option is deprecated and will be removed in future releases. Use unsafeFlags subsection instead

Value type	Example
