MariaDB Docker Compose Example

MariaDB with a named volume and health check.

The compose.yaml

name: mariadb
services:
  db:
    image: mariadb:11
    restart: unless-stopped
    environment:
      MARIADB_DATABASE: app
      MARIADB_USER: app
      MARIADB_PASSWORD: ${MARIADB_PASSWORD}
      MARIADB_ROOT_PASSWORD: ${MARIADB_ROOT_PASSWORD}
    volumes:
      - mariadata:/var/lib/mysql
    healthcheck:
      test:
        - CMD-SHELL
        - healthcheck.sh --connect --innodb_initialized
      interval: 30s
      timeout: 10s
      retries: 3
      start_period: 20s
    logging:
      driver: json-file
      options:
        max-size: 10m
        max-file: '3'
volumes:
  mariadata: {}

Start it up

# Validate the configuration (does not start anything):
docker compose -f compose.yaml config

# Pull images and start in the background:
docker compose -f compose.yaml pull
docker compose -f compose.yaml up -d

# Check status and follow logs:
docker compose -f compose.yaml ps
docker compose -f compose.yaml logs -f

# Stop and remove (named volumes are kept):
docker compose -f compose.yaml down

FAQ

How do I run this MariaDB Docker Compose file?

Save it as compose.yaml, then run `docker compose up -d`. Validate first with `docker compose config` and follow logs with `docker compose logs -f`.

Do I need a version field in the MariaDB Compose file?

No — modern Docker Compose does not require a top-level version field, and this example does not include one.

How do I customize this MariaDB template?

Open it in the free Docker Compose Generator to change images, ports, volumes, networks, environment variables, and health checks visually, then download your compose.yaml.
