Custom Resource options reference¶

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

PerconaServerMySQL Custom Resource with options for the cluster,
PerconaServerMySQLBackup Custom Resource contains options for Percona XtraBackup used to backup Percona Server for MySQL
PerconaServerMySQLRestore Custom Resource contains options for restoring Percona Server for MySQL from backups.

PerconaServerMySQL Custom Resource options¶

Percona Server for MySQL managed by the Operator is configured via the spec section of the deploy/cr.yaml file.

The metadata part of PerconaServerMySQL Custom Resource contains the following keys:

name (cluster1 by default) sets the name of your Percona Server for MySQL 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-mysql-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-mysql-pvc if present, activates the Finalizer which deletes Persistent Volume Claims for Percona Server for MySQL Pods 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 elements of the deploy/cr.yaml are the following ones:
