## Using `docker-compose.yaml`
Please be aware this file has not undergone internal testing. Consequently, we advise its use exclusively for development or testing purposes. For production-ready deployments, we highly recommend utilizing its associated [Bitnami Helm chart](https://github.com/bitnami/charts/tree/main/bitnami/mariadb).
## Persisting your database
If you remove the container all your data will be lost, and the next time you run the image the database will be reinitialized. To avoid this loss of data, you should mount a volume that will persist even after the container is removed.
For persistence you should mount a directory at the `/bitnami/mariadb` path. If the mounted directory is empty, it will be initialized on the first run.
```console
docker run \
-e ALLOW_EMPTY_PASSWORD=yes \
-v /path/to/mariadb-persistence:/bitnami/mariadb \
bitnami/mariadb:latest
```

Containers attached to the same network can communicate with each other using the container name as the hostname.
### Using the Command Line
In this example, we will create a MariaDB client instance that will connect to the server instance that is running on the same docker network as the client.
#### Step 1: Create a network
```console
docker network create app-tier --driver bridge
```
#### Step 2: Launch the MariaDB server instance
Use the `--network app-tier` argument to the `docker run` command to attach the MariaDB container to the `app-tier` network.
```console
docker run -d --name mariadb-server \
-e ALLOW_EMPTY_PASSWORD=yes \
--network app-tier \
bitnami/mariadb:latest
```
#### Step 3: Launch your MariaDB client instance
Finally we create a new container instance to launch the MariaDB client and connect to the server created in the previous step:
```console
docker run -it --rm \
--network app-tier \
bitnami/mariadb:latest mysql -h mariadb-server -u root
```
### Using a Docker Compose file
When not specified, Docker Compose automatically sets up a new network and attaches all deployed services to that network. However, we will explicitly define a new `bridge` network named `app-tier`. In this example we assume that you want to connect to the MariaDB server from your own custom application image which is identified in the following snippet by the service name `myapp`.
```yaml
version: '2'
networks:
app-tier:
driver: bridge
services:
mariadb:
image: bitnami/mariadb:latest
environment:
- ALLOW_EMPTY_PASSWORD=yes
networks:
- app-tier
myapp:
image: YOUR_APPLICATION_IMAGE
networks:
- app-tier
```
> **IMPORTANT**:
>
> 1. Please update the `YOUR_APPLICATION_IMAGE` placeholder in the above snippet with your application image
> 2. In your application container, use the hostname `mariadb` to connect to the MariaDB server
Launch the containers using:
```console
docker-compose up -d

While the `.sh` scripts are executed in all the nodes; the `.sql` and `.sql.gz` scripts are only executed in the master nodes. The reason behind this differentiation is that the `.sh` scripts allow adding conditions to determine what is the node running the script, while these conditions can't be set using `.sql` nor `sql.gz` files. This way it is possible to cover different use cases depending on their needs.

Passing the `MARIADB_ROOT_PASSWORD` environment variable when running the image for the first time will set the password of the `MARIADB_ROOT_USER` user to the value of `MARIADB_ROOT_PASSWORD`.
```console
docker run --name mariadb -e MARIADB_ROOT_PASSWORD=password123 bitnami/mariadb:latest
```
or by modifying the [`docker-compose.yml`](https://github.com/bitnami/containers/blob/main/bitnami/mariadb/docker-compose.yml) file present in this repository:

environment:
- MARIADB_ROOT_PASSWORD=password123
...
```
**Warning** The `MARIADB_ROOT_USER` user is always created with remote access. It's suggested that the `MARIADB_ROOT_PASSWORD` env variable is always specified to set a password for the `MARIADB_ROOT_USER` user. In case you want to allow the `MARIADB_ROOT_USER` user to access the database without a password set the environment variable `ALLOW_EMPTY_PASSWORD=yes`. **This is recommended only for development**.
### Allowing empty passwords
By default the MariaDB image expects all the available passwords to be set. In order to allow empty passwords, it is necessary to set the `ALLOW_EMPTY_PASSWORD=yes` env variable. This env variable is only recommended for testing or development purposes. We strongly recommend specifying the `MARIADB_ROOT_PASSWORD` for any other scenario.
```console
docker run --name mariadb -e ALLOW_EMPTY_PASSWORD=yes bitnami/mariadb:latest

### Creating a database on first run
By passing the `MARIADB_DATABASE` environment variable when running the image for the first time, a database will be created. This is useful if your application requires that a database already exists, saving you from having to manually create the database using the MySQL client.
```console
docker run --name mariadb \
-e ALLOW_EMPTY_PASSWORD=yes \
-e MARIADB_DATABASE=my_database \
bitnami/mariadb:latest
```

- ALLOW_EMPTY_PASSWORD=yes
- MARIADB_DATABASE=my_database
...
```
### Creating a database user on first run
You can create a restricted database user that only has permissions for the database created with the [`MARIADB_DATABASE`](#creating-a-database-on-first-run) environment variable. To do this, provide the `MARIADB_USER` environment variable and to set a password for the database user provide the `MARIADB_PASSWORD` variable (alternatively, you can set the `MARIADB_PASSWORD_FILE` with the path to a file that contains the user password). MariaDB supports different authentication mechanisms, such as `pam` or `mysql_native_password`. To set it, use the `MARIADB_AUTHENTICATION_PLUGIN` variable.
```console
docker run --name mariadb \
-e ALLOW_EMPTY_PASSWORD=yes \
-e MARIADB_USER=my_user \
-e MARIADB_PASSWORD=my_password \
-e MARIADB_DATABASE=my_database \

In a replication cluster you can have one master and zero or more slaves. When replication is enabled the master node is in read-write mode, while the slaves are in read-only mode. For best performance its advisable to limit the reads to the slaves.
> **Note**: you can use the [mariadb-galera image](https://github.com/bitnami/containers/blob/main/bitnami/mariadb-galera) to set up a master-master replication cluster
>
#### Step 1: Create the replication master
The first step is to start the MariaDB master.
```console
docker run --name mariadb-master \
-e MARIADB_ROOT_PASSWORD=master_root_password \
-e MARIADB_REPLICATION_MODE=master \
-e MARIADB_REPLICATION_USER=my_repl_user \
-e MARIADB_REPLICATION_PASSWORD=my_repl_password \
-e MARIADB_USER=my_user \
-e MARIADB_PASSWORD=my_password \
-e MARIADB_DATABASE=my_database \
bitnami/mariadb:latest
```
In the above command the container is configured as the `master` using the `MARIADB_REPLICATION_MODE` parameter. A replication user is specified using the `MARIADB_REPLICATION_USER` and `MARIADB_REPLICATION_PASSWORD` parameters.
#### Step 2: Create the replication slave
Next we start a MariaDB slave container.
```console
docker run --name mariadb-slave --link mariadb-master:master \
-e MARIADB_REPLICATION_MODE=slave \
-e MARIADB_REPLICATION_USER=my_repl_user \
-e MARIADB_REPLICATION_PASSWORD=my_repl_password \
-e MARIADB_MASTER_HOST=master \
-e MARIADB_MASTER_ROOT_PASSWORD=master_root_password \
bitnami/mariadb:latest
```
In the above command the container is configured as a `slave` using the `MARIADB_REPLICATION_MODE` parameter. The `MARIADB_MASTER_HOST`, `MARIADB_MASTER_ROOT_USER` and `MARIADB_MASTER_ROOT_PASSWORD` parameters are used by the slave to connect to the master. It also takes a dump of the existing data in the master server. The replication user credentials are specified using the `MARIADB_REPLICATION_USER` and `MARIADB_REPLICATION_PASSWORD` parameters and should be the same as the one specified on the master.
You now have a two node MariaDB master/slave replication cluster up and running. You can scale the cluster by adding/removing slaves without incurring any downtime.
With Docker Compose the master/slave replication can be setup using:
```yaml
version: '2'
services:
mariadb-master:
image: bitnami/mariadb:latest
ports:
- 3306
volumes:
- /path/to/mariadb-persistence:/bitnami/mariadb
environment:
- MARIADB_REPLICATION_MODE=master
- MARIADB_REPLICATION_USER=repl_user
- MARIADB_REPLICATION_PASSWORD=repl_password
- MARIADB_ROOT_PASSWORD=master_root_password
- MARIADB_USER=my_user
- MARIADB_PASSWORD=my_password
- MARIADB_DATABASE=my_database
mariadb-slave:
image: bitnami/mariadb:latest
ports:
- 3306
depends_on:
- mariadb-master
environment:
- MARIADB_REPLICATION_MODE=slave
- MARIADB_REPLICATION_USER=repl_user
- MARIADB_REPLICATION_PASSWORD=repl_password
- MARIADB_MASTER_HOST=mariadb-master
- MARIADB_MASTER_PORT_NUMBER=3306
- MARIADB_MASTER_ROOT_PASSWORD=master_root_password
```
Scale the number of slaves using:
```console
docker-compose up --detach --scale mariadb-master=1 --scale mariadb-slave=3
```
The above command scales up the number of slaves to `3`. You can scale down in the same manner.
> **Note**: You should not scale up/down the number of master nodes. Always have only one master node running.
> **NOTE**: you can use the [mariadb-galera image](https://github.com/bitnami/containers/blob/main/bitnami/mariadb-galera) to set up a master-master replication cluster
### Configuration file
The image looks for user-defined configurations in `/opt/bitnami/mariadb/conf/my_custom.cnf`. Create a file named `my_custom.cnf` and mount it at `/opt/bitnami/mariadb/conf/my_custom.cnf`.
For example, in order to override the `max_allowed_packet` directive:
#### Step 1: Write your `my_custom.cnf` file with the following content
```config
[mysqld]
max_allowed_packet=32M
```
#### Step 2: Run the mariaDB image with the designed volume attached
```console
docker run --name mariadb \
-p 3306:3306 \
-e ALLOW_EMPTY_PASSWORD=yes \
-v /path/to/my_custom.cnf:/opt/bitnami/mariadb/conf/my_custom.cnf:ro \
-v /path/to/mariadb-persistence:/bitnami/mariadb \
bitnami/mariadb:latest
```
or by modifying the [`docker-compose.yml`](https://github.com/bitnami/containers/blob/main/bitnami/mariadb/docker-compose.yml) file present in this repository:
```yaml
services:

...
volumes:
- /path/to/my_custom.cnf:/opt/bitnami/mariadb/conf/my_custom.cnf:ro
- /path/to/mariadb-persistence:/bitnami/mariadb

```
After that, your changes will be taken into account in the server's behaviour.

## Maintenance
### Upgrade this image
Bitnami provides up-to-date versions of MariaDB, including security patches, soon after they are made upstream. We recommend that you follow these steps to upgrade your container.
#### Step 1: Get the updated image
```console
docker pull bitnami/mariadb:latest
```
or if you're using Docker Compose, update the value of the image property to
`bitnami/mariadb:latest`.
#### Step 2: Stop and backup the currently running container
Stop the currently running container using the command
```console
docker stop mariadb
```
or using Docker Compose:
```console
docker-compose stop mariadb
```
Next, take a snapshot of the persistent volume `/path/to/mariadb-persistence` using:
```console
rsync -a /path/to/mariadb-persistence /path/to/mariadb-persistence.bkp.$(date +%Y%m%d-%H.%M.%S)
```
You can use this snapshot to restore the database state should the upgrade fail.
#### Step 3: Remove the currently running container
```console
docker rm -v mariadb
```
or using Docker Compose:
```console
docker-compose rm -v mariadb
```
#### Step 4: Run the new image
Re-create your container from the new image.
```console
docker run --name mariadb bitnami/mariadb:latest
```
or using Docker Compose:
```console
docker-compose up mariadb
```
> **Note**: Automatic upgrade behavior at startup can be forced setting the env var `MARIADB_UPGRADE` to `FORCE` (that will run `mysql_upgrade --force`)
