Custom Resource options reference

Percona Operator for MySQL uses Custom Resources to manage options for the various components of the cluster.

  • PerconaXtraDBCluster Custom Resource with Percona XtraDB Cluster options,
  • PerconaXtraDBClusterBackup and PerconaXtraDBClusterRestore Custom Resources contain options for Percona XtraBackup used to backup Percona XtraDB Cluster and to restore it from backups.

PerconaXtraDBCluster Custom Resource options

PerconaXtraDBCluster Custom Resource contains options for Percona XtraDB Cluster and can be configured via the deploy/cr.yaml configuration file.

The metadata part contains the following keys:

  • name (cluster1 by default) sets the name of your Percona XtraDB Cluster; it should include only URL-compatible characters , not exceed 22 characters, start with an alphabetic character, and end with an alphanumeric character;
  • finalizers subsection:
    • percona.com/delete-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).
    • percona.com/delete-pxc-pvc if present, activates the Finalizer which deletes Persistent Volume Claims for Percona XtraDB Cluster Pods after the cluster deletion event (off by default).
    • percona.com/delete-proxysql-pvc if present, activates the Finalizer which deletes Persistent Volume Claim for ProxySQL Pod after the cluster deletion event (off by default).
    • percona.com/delete-ssl if present, activates the Finalizer which deletes objects, created for SSL (Secret, certificate, and issuer) after the cluster deletion event (off by default).

The toplevel spec elemets of the deploy/cr.yaml are the following ones:
