We utilise the docker manifest for multi-platform awareness. More information is available from docker [here](https://distribution.github.io/distribution/spec/manifest-v2-2/#manifest-list) and our announcement [here](https://blog.linuxserver.io/2019/02/21/the-lsio-pipeline-project/).
Simply pulling `lscr.io/linuxserver/mariadb:latest` should retrieve the correct image for your arch, but you can also pull specific arch images via tags.
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
### Loading passwords and users from files
The `MYSQL_ROOT_PASSWORD MYSQL_DATABASE MYSQL_USER MYSQL_PASSWORD REMOTE_SQL` env values can be set in a file:
After running the above commands, you may need to run the upgrade command again.
### Upgrading
When this container initializes, if `MYSQL_ROOT_PASSWORD` is set an upgrade check will run. If an upgrade is required the log will indicate the need stop any services that are accessing databases in this container, and then run the command:
Containers 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.
| `MYSQL_ROOT_PASSWORD=ROOT_ACCESS_PASSWORD` | Set this to root password for installation (minimum 4 characters & non-alphanumeric passwords must be properly escaped). |
| `MYSQL_PASSWORD=DATABASE_PASSWORD` | Set this to the password you want to use for you MYSQL_USER (minimum 4 characters & non-alphanumeric passwords must be properly escaped). |
For all of our images we provide the ability to override the default umask settings for services started within the containers using the optional `-e UMASK=022` setting.
Keep in mind umask is not chmod it subtracts from permissions based on it's value it does not add. Please read up [here](https://en.wikipedia.org/wiki/Umask) before asking for support.
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`.

We publish various [Docker Mods](https://github.com/linuxserver/docker-mods) to enable additional functionality within the containers. The list of Mods available for this image (if any) as well as universal mods that can be applied to any one of our images can be accessed via the dynamic badges above.
Most of our images are static, versioned, and require an image update and container recreation to update the app inside. With some exceptions (noted in the relevant readme.md), we do not recommend or support updating apps inside the container. Please consult the [Application Setup](#application-setup) section above to see if it is recommended for the image.
Below are the instructions for updating containers:
### Via Docker Compose
* Update images:
* All images:
```bash
docker-compose pull
```
* Single image:
```bash
docker-compose pull mariadb
```
* Update containers:
* All containers:
```bash
docker-compose up -d
```
* Single container:
```bash
docker-compose up -d mariadb
```
* You can also remove the old dangling images:
```bash
docker image prune
```
### Via Docker Run
* Update the image:
```bash
docker pull lscr.io/linuxserver/mariadb:latest
```
* Stop the running container:
```bash
docker stop mariadb
```
* Delete the container:
```bash
docker rm mariadb
```
* Recreate a new container with the same docker run parameters as instructed above (if mapped correctly to a host folder, your `/config` folder and settings will be preserved)
We recommend [Diun](https://crazymax.dev/diun/) for update notifications. Other tools that automatically update containers unattended are not recommended or supported.
## Building locally
If you want to make local modifications to these images for development purposes or just to customize the logic:
* **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.
