apiVersion: deployments.plural.sh/v1alpha1
kind: GeneratedSecret
metadata:
  name: plrl-04-wordpress-config
  namespace: examples
spec:
  destinations:
    - name: plrl-04-wordpress-config
      namespace: examples
  template:
    dbUser: admin
    dbPassword: '{{ "{{ 32 | randAlphaNum " }}}}'
    dbRootPassword: '{{ "{{ 32 | randAlphaNum " }}}}'
    dbReplicationPassword: '{{ "{{ 32 | randAlphaNum " }}}}'
    dbName: 'bitnami_wordpress'
    dbSecret: 'wordpress-mariadb'
    wordpressSecret: 'wordpress'
    wordpressPassword: '{{ "{{ 32 | randAlphaNum " }}}}'
