linuxserver/mariadb

Mariadb is one of the most popular database servers. Made by the original developers of MySQL.

Supported Architectures

Our images support multiple architectures such as x86-64, arm64 and armhf. We utilise the docker manifest for multi-platform awareness. More information is available from docker here.

Simply pulling linuxserver/mariadb should retrieve the correct image for your arch, but you can also pull specific arch images via tags.

The architectures supported by this image are:

Architecture	Tag
x86-64	amd64-latest
arm64	arm64v8-latest
armhf	arm32v6-latest

Usage

Here are some example snippets to help you get started creating a container from this image.

docker

docker create \
  --name=mariadb \
  -e PUID=1001 \
  -e PGID=1001 \
  -e MYSQL_ROOT_PASSWORD=<DATABASE PASSWORD> \
  -e TZ=Europe/London \
  -p 3306:3306 \
  -v <path to data>:/config \
  --restart unless-stopped \
  linuxserver/mariadb

docker-compose

Compatible with docker-compose v2 schemas.

---
version: "2"
services:
  mariadb:
    image: linuxserver/mariadb
    container_name: mariadb
    environment:
      - PUID=1001
      - PGID=1001
      - MYSQL_ROOT_PASSWORD=<DATABASE PASSWORD>
      - TZ=Europe/London
    volumes:
      - <path to data>:/config
    ports:
      - 3306:3306
    mem_limit: 4096m
    restart: unless-stopped

Parameters

Docker images are configured using parameters passed at runtime (such as those above). These parameters are separated by a colon and indicate <external>:<internal> respectively. For example, -p 8080:80 would expose port 80 from inside the container to be accessible from the host's IP on port 8080 outside the container.

Ports (`-p`)

Parameter	Function
`3306`	Mariadb listens on this port.

Environment Variables (`-e`)

Env	Function
`PUID=1001`	for UserID - see below for explanation
`PGID=1001`	for GroupID - see below for explanation
`MYSQL_ROOT_PASSWORD=<DATABASE PASSWORD>`	Set this to root password for installation (minimum 4 characters).
`TZ=Europe/London`	Specify a timezone to use EG Europe/London.

Volume Mappings (`-v`)

Volume	Function
`/config`	Contains the db itself and all assorted settings.

User / Group Identifiers

When using volumes (-v flags), permissions issues can arise between the host OS and the container, we avoid this issue by allowing you to specify the user PUID and group PGID.

Ensure any volume directories on the host are owned by the same user you specify and any permissions issues will vanish like magic.

In this instance PUID=1001 and PGID=1001, to find yours use id user as below:

  $ id username
    uid=1001(dockeruser) gid=1001(dockergroup) groups=1001(dockergroup)

Application Setup

If you didn't set a password during installation, (see logs for warning) use mysqladmin -u root password <PASSWORD> to set one at the docker prompt...

NOTE changing the MYSQL_ROOT_PASSWORD variable after the container has set up the initial databases has no effect, use the mysqladmin tool to change your mariadb password.

Unraid users, it is advisable to edit the template/webui after setup and remove reference to this variable.

Find custom.cnf in /config for config changes (restart container for them to take effect) , the databases in /config/databases and the log in /config/log/myqsl

Support Info

Shell access whilst the container is running:
- docker exec -it mariadb /bin/bash
To monitor the logs of the container in realtime:
- docker logs -f mariadb
Container version number
- docker inspect -f '{{ index .Config.Labels "build_version" }}' mariadb
Image version number
- docker inspect -f '{{ index .Config.Labels "build_version" }}' linuxserver/mariadb
