Dockerfile to build MySQL Docker images with data

Docker MySQL image with data

This repository provides a Dockerfile to build MySQL Docker images with data.

Usage

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

Before:

services:
  mysql:
    image: mysql:8.1.0
    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#0.0.1
      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, 0.0.1 in this case, try to always use the latest release.
• 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.
