Standalone MariaDB

MariaDB Enterprise Operator allows you to configure standalone MariaDB Enterprise Server instances. To achieve this, you can either omit the replicas field or set it to 1:

apiVersion: enterprise.mariadb.com/v1alpha1
kind: MariaDB
metadata:
  name: mariadb
spec:
  rootPasswordSecretKeyRef:
    name: mariadb
    key: password

  replicas: 1

  port: 3306

  storage:
    size: 1Gi

  myCnf: |
    [mariadb]
    bind-address=*
    default_storage_engine=InnoDB
    binlog_format=row
    innodb_autoinc_lock_mode=2
    innodb_buffer_pool_size=800M
    max_allowed_packet=256M

  resources:
    requests:
      cpu: 500m
      memory: 1Gi
    limits:
      memory: 1Gi

  metrics:
    enabled: true

Whilst this can be useful for development and testing, it is not recommended for production use because of the following reasons:

• Single point of failure

• Upgrades require downtime

• Only vertical scaling is possible

For achieving high availability, we recommend deploying a Galera cluster. Refer to the Galera and High Availability sections for more information.
