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](https://github.com/docker/distribution/blob/master/docs/spec/manifest-v2-2.md#manifest-list) and our announcement [here](https://blog.linuxserver.io/2019/02/21/the-lsio-pipeline-project/). 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 | arm32v7-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=1000 \ -e PGID=1000 \ -e MYSQL_ROOT_PASSWORD= \ -e TZ=Europe/London \ -e MYSQL_DATABASE= `#optional` \ -e MYSQL_USER= `#optional` \ -e MYSQL_PASSWORD= `#optional` \ -p 3306:3306 \ -v :/config \ --restart unless-stopped \ linuxserver/mariadb ``` ### docker-compose Compatible with docker-compose v2 schemas. ```yaml --- version: "2" services: mariadb: image: linuxserver/mariadb container_name: mariadb environment: - PUID=1000 - PGID=1000 - MYSQL_ROOT_PASSWORD= - TZ=Europe/London - MYSQL_DATABASE= #optional - MYSQL_USER= #optional - MYSQL_PASSWORD= #optional volumes: - :/config ports: - 3306:3306 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 `:` 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=1000` | for UserID - see below for explanation | | `PGID=1000` | for GroupID - see below for explanation | | `MYSQL_ROOT_PASSWORD=` | Set this to root password for installation (minimum 4 characters). | | `TZ=Europe/London` | Specify a timezone to use EG Europe/London. | | `MYSQL_DATABASE=` | Specify the name of a database to be created on image startup. | | `MYSQL_USER=` | This user will have superuser access to the database specified by MYSQL_DATABASE. | | `MYSQL_PASSWORD=` | Set this to the password you want to use for you MYSQL_USER (minimum 4 characters). | ### 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=1000` and `PGID=1000`, to find yours use `id user` as below: ``` $ id username uid=1000(dockeruser) gid=1000(dockergroup) groups=1000(dockergroup) ``` ## Application Setup If you didn't set a password during installation, (see logs for warning) use `mysqladmin -u root 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. NOTE if you want to use (MYSQL_DATABASE MYSQL_USER MYSQL_PASSWORD) **all three** of these variables need to be set you cannot pick and choose. 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` ## Versions * **23.03.19:** - Switching to new Base images, shift to arm32v7 tag. * **07.03.19:** - Add ability to setup a database and default user on first spinup. * **26.01.19:** - Add pipeline logic and multi arch. * **10.09.18:** - Rebase to ubuntu bionic and use 10.3 mariadb repository. * **09.12.17:** - Fix continuation lines. * **12.09.17:** - Gracefully shut down mariadb. * **27.10.16:** - Implement linting suggestions on database init script. * **11.10.16:** - Rebase to ubuntu xenial, add version labelling. * **09.03.16:** - Update to mariadb 10.1. Change to use custom.cnf over my.cnf in /config. Restructured init files to change config options on startup, rather than in the dockerfile. * **26.01.16:** - Change user of mysqld_safe script to abc, better unclean shutdown handling on restart. * **23.12.15:** - Remove autoupdating, between some version updates the container breaks. * **12.08.15:** - Initial Release.
