MySQL chart

This chart deploys Percona XtraDB Cluster through the Percona operator. It is owned by Apps/Storage/Database/MySQL.yaml.

The owning ApplicationSet creates one MySQL deployment in each of the three explicit core fleet clusters (dc1-k3s-node1, core-dc1-talos-prod, and core-home1-talos-prod) when the matching core cluster object is present. The cluster selector supplies the environment and namespace; the chart resources remain namespaced and use the existing Vault-backed credential flow.

Components

  • PXC database, HAProxy and ProxySQL configuration.
  • TLS and LDAP authentication.
  • Crossplane-generated S3 backup user.
  • ExternalSecret/PushSecret credential synchronization.
  • S3 backup storage configuration.

The chart follows the Percona XtraDB Cluster Helm chart documentation and the External Secrets Operator documentation.

Initial deployment currently has a known LDAP/plugin ordering problem: enabling LDAP configuration during first initialization can cause startup failure. Treat the existing manual disable/re-enable process as a defect to automate and test, not a normal safety guarantee.

Before changes, verify cluster size/quorum, storage capacity, TLS, LDAP, proxy health and a recent backup. Although S3 storage is configured, scheduled backup entries may be disabled; confirm actual backup objects and perform an isolated restore test.
