Docker MySQL image with data

This repository simplifies building MySQL or MariaDB Docker images with data.

Usage

Adjust your Docker Compose database service by adding a build section and changing the image.

MySQL

Before:

services:
  mysql:
    image: mysql:8.1.0
    environment:
      MYSQL_DATABASE: database_name
      MYSQL_USER: user_name
      MYSQL_PASSWORD: user_password
      MYSQL_ROOT_PASSWORD: root_password
    healthcheck:
      test: ["CMD", "mysqladmin" ,"ping", "-h", "localhost"]
      interval: 10s
      timeout: 5s
      retries: 10

After:

services:
  mysql:
    build:
      context: https://github.com/pagemachine/docker-mysql-data.git#x.y.z
      dockerfile: mysql.Dockerfile
      additional_contexts:
        data: ./data
      args:
        MYSQL_IMAGE_VERSION: 8.1.0
        MYSQL_DATABASE: database_name
        MYSQL_USER: user_name
        MYSQL_PASSWORD: user_password
        MYSQL_ROOT_PASSWORD: root_password
    healthcheck:
      test: ["CMD", "mysqladmin" ,"ping", "-h", "localhost"]
      interval: 10s
      timeout: 5s
      retries: 10
    image: registry.example/my-project/mysql:latest
  • build.context points to the URL of this GitHub repository, the fragment refers to a release, x.y.z in this case, try to always use the latest release.
  • build.dockerfile is the mysql.Dockerfile
  • build.additional_contexts.data must be defined and point to a local directory with *.sql, .sql.gz or .sh files to use for populating the database on build.
  • build.args.MYSQL_IMAGE_VERSION must be a valid tag of the mysql Docker image.
  • build.args.MYSQL_DATABASE is the name of the database to create.
  • build.args.MYSQL_USER is the username to set up for the database.
  • build.args.MYSQL_PASSWORD is the password to set for the database user.
  • build.args.MYSQL_ROOT_PASSWORD is the password of the root user.
  • image should set a persistent image name/tag and a registry to push this image to, this way other users will automatically pull the prebuilt image instead of building it again.

MariaDB

Before:

services:
  mariadb:
    image: mariadb:10.5.27
    environment:
      MARIADB_DATABASE: database_name
      MARIADB_USER: user_name
      MARIADB_PASSWORD: user_password
      MARIADB_ROOT_PASSWORD: root_password
    healthcheck:
      test: ["CMD", "healthcheck.sh", "--connect", "--innodb_initialized"]
      interval: 10s
      timeout: 5s
      retries: 10

After:

services:
  mariadb:
    build:
      context: https://github.com/pagemachine/docker-mysql-data.git#x.y.z
      dockerfile: mariadb.Dockerfile
      additional_contexts:
        data: ./data
      args:
        MARIADB_IMAGE_VERSION: 10.5.27
        MARIADB_DATABASE: database_name
        MARIADB_USER: user_name
        MARIADB_PASSWORD: user_password
        MARIADB_ROOT_PASSWORD: root_password
    healthcheck:
      test: ["CMD", "healthcheck.sh", "--connect", "--innodb_initialized"]
      interval: 10s
      timeout: 5s
      retries: 10
    image: registry.example/my-project/mariadb:latest
