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 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=1000 \
-e PGID=1000 \
-e MYSQL_ROOT_PASSWORD=<DATABASE PASSWORD> \
-e TZ=Europe/London \
-e MYSQL_DATABASE=<USER DB NAME> `#optional` \
-e MYSQL_USER=<MYSQL USER> `#optional` \
-e MYSQL_PASSWORD=<DATABASE PASSWORD> `#optional` \
-p 3306:3306 \
-v <path to data>:/config \
--restart unless-stopped \
linuxserver/mariadb
docker-compose
Compatible with docker-compose v2 schemas.

image: linuxserver/mariadb
container_name: mariadb
environment:
- PUID=1000
- PGID=1000
- MYSQL_ROOT_PASSWORD=<DATABASE PASSWORD>
- TZ=Europe/London
- MYSQL_DATABASE=<USER DB NAME> #optional
- MYSQL_USER=<MYSQL USER> #optional

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=1000 |
for UserID - see below for explanation |
PGID=1000 |
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. |
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. |
MYSQL_PASSWORD=<DATABASE 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 <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
