How to run Mariadb with Docker and Docker-Compose

Prerequisites:

Docker installed locally and permissions to use it to launch containers and Docker compose is installed locally.

Install docker / dockercompose On Ubuntu:

sudo apt-get update
sudo apt upgrade -y
sudo apt install docker.io -y
sudo apt install curl vim -y
sudo curl -L "https://github.com/docker/compose/releases/download/1.29.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
sudo chmod +x /usr/local/bin/docker-compose
docker-compose --version
# sudo usermod -aG docker [USER]

Using Docker Run Command To Create MariaDB

Create data dir:

mkdir -p ~/apps/mariadb/data

Run the container

docker run -d --name my-mariadb -p 3306:3306 -v ~/apps/mariadb/data:/var/lib/mysql -e MYSQL_ROOT_PASSWORD=S3cret -e MYSQL_PASSWORD=An0thrS3crt -e MYSQL_USER=citizix_user  -e MYSQL_DATABASE=citizix_db mariadb

In the above command:

• -d instructs docker container to run container in background and print container ID.
• -p is for port mapping.
• -v directive is used to mount volumes. 
• -e argument is for the environment variables.

To check that our container is running use docker ps command:

Using DockerCompose To Create MariaDB

Docker Compose allows you to define the service (Mariadb in our case) with properties like the image to use, ports to expose, volumes to mount and environment variables.

Save this as docker-compose.yaml:

version: '3.3'

services:
  mariadb:
    image: mariadb:10.7
    ports:
      - 3306:3306
    volumes:
      - ~/apps/mariadb:/var/lib/mysql
    environment:
      - MYSQL_ROOT_PASSWORD=S3cret
      - MYSQL_PASSWORD=An0thrS3crt
      - MYSQL_USER=citizix_user
      - MYSQL_DATABASE=citizix_db
    restart: on-failure

Now bring up the containers:

docker-compose up -d

The commands:

• up brings up the container
• -d in a detached mode

Verify the container processes using docker-compose ps : To login to the container and login to Mariadb, use this:
