mariadb |
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 and our announcement here.
Simply pulling ghcr.io/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 |
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.
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:
/config/env
Using the following format:
MYSQL_ROOT_PASSWORD="ROOT_ACCESS_PASSWORD"
MYSQL_DATABASE="USER_DB_NAME"
MYSQL_USER="MYSQL_USER"
MYSQL_PASSWORD="DATABASE_PASSWORD"
REMOTE_SQL="http://URL1/your.sql,https://URL2/your.sql"
These settings can be mixed and matched with Docker ENV settings as you require, but the settings in the file will always take precedence.
Bootstrapping a new instance
We support a one time run of custom sql files on init. In order to use this place *.sql
files in:
/config/initdb.d/
This will have the same effect as setting the REMOTE_SQL
environment variable. The sql will only be run on the containers first boot and setup.
Usage
To help you get started creating a container from this image you can either use docker-compose or the docker cli.

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=1000 |
for UserID - see below for explanation |
PGID=1000 |
for GroupID - see below for explanation |
MYSQL_ROOT_PASSWORD=ROOT_ACCESS_PASSWORD |
Set this to root password for installation (minimum 4 characters). |
TZ=Europe/London |
Specify a timezone to use EG Europe/London. |
MYSQL_DATABASE=USER_DB_NAME |
Specify the name of a database to be created on image startup. |
MYSQL_USER=MYSQL_USER |
This user will have superuser access to the database specified by MYSQL_DATABASE (do not use root here). |
MYSQL_PASSWORD=DATABASE_PASSWORD |
Set this to the password you want to use for you MYSQL_USER (minimum 4 characters). |
REMOTE_SQL=http://URL1/your.sql,https://URL2/your.sql |
Set this to ingest sql files from an http/https endpoint (comma seperated array). |
Volume Mappings (-v
)
Volume | Function |
---|---|
/config |
Contains the db itself and all assorted settings. |
Environment variables from files (Docker secrets)
You can set any environment variable from a file by using a special prepend FILE__
.
As an example:
-e FILE__PASSWORD=/run/secrets/mysecretpassword
Will set the environment variable PASSWORD
based on the contents of the /run/secrets/mysecretpassword
file.
Umask for running applications
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 before asking for support.
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)
Docker Mods
We publish various 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.
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" }}' ghcr.io/linuxserver/mariadb
