Init container lacks command line argument for mariadb

[Wolfgang1966]

Describe your Issue

Since a few releases the init container that checks for availability of the database no longer works correctly for mariadb. As a consequence the database check constantly fails and nextcloud itself never comes up.

Logs and Errors

The logs of the init container show repeatedly:

ERROR 2026 (HY000): TLS/SSL error: SSL is required, but the server does not support it  

The fix is to add the command line flag --skip-ssl to the command line of the init container. However, as I don't know whether this may break other setups I did not simply create a PR containing this flag. A more elaborate solution may be required, e.g. introducing a value that can be set optionally.

Describe your Environment

• Kubernetes distribution: k3s

• Helm Version (or App that manages helm):
  controlled by fluxcd

• Helm Chart Version: 7.0.3
  (but also happened with a few previous versions already)

• values.yaml:
  (relevant part)

    mariadb:
      enabled: true
      auth:
        existingSecret: "mariadb-secret"
      primary:
        persistence:
          enabled: true

With the help of Copilot I found a workaround:

Added the following section to my helm release definition;

  postRenderers:
    - kustomize:
        patches:
          - patch: |-
              apiVersion: apps/v1
              kind: Deployment
              metadata:
                name: nextcloud-nextcloud
              spec:
                template:
                  spec:
                    initContainers:
                      - name: mariadb-isalive
                        command:
                          - sh
                          - -c
                          - until mysql --host=nextcloud-nextcloud-mariadb --skip-ssl --user=${MYSQL_USER} --password=${MYSQL_PASSWORD} --execute="SELECT 1;"; do echo waiting for mysql; sleep 2; done;
            target:
              kind: Deployment
              name: nextcloud-nextcloud

This added the missing parameter.
