Docker production environment for running Redmine.

About

This configuration runs 5 containers to have a basic redmine working:

• a container with ruby, rails, and redmine using the local Dockerfile and exposed on port 3000.
• a container with mysql as database
• a busybox container to permanently store the data from MySQL
• a container with nginx to serve redmine on https on standard ports (80 and 443)
• a container with postfix to send notifications

Initial Deployment

1. Pull a busybox image to get a very lightweight container to play with:

    $ docker pull busybox
   

2. Create a data volume container that will hold all MySQL data:

    $ docker create --name redminedbdata busybox
   

   Never delete this container or you will loose all MySQL data! Also ensure a backup procedure is active and well tested.

3. Grab an official MySQL image

    $ docker pull mysql
    $ docker run -d --volumes-from redminedbdata \
        -e MYSQL_ROOT_PASSWORD=<root_psswd> -e MYSQL_DATABASE=redmine -e MYSQL_USER=redmine \
        -e MYSQL_PASSWORD=<redmine_psswd> --name tmpdb mysql
   

4. Create user and database by connecting to the mysql container:

    $ docker exec -ti db /bin/bash
    $ mysql
    $ mysql> CREATE USER 'lwa'@'%' IDENTIFIED BY '=<redmine_psswd>';
    $ mysql> CREATE DATABASE 'redmine';
    $ mysql> GRANT ALL PRIVILEGES ON redmine.* TO 'redmine'@'%'
   

5. The data is stored in the redminedbdata container, it's safe to stop and delete the running MySQL container:

    $ docker stop tmpdb
    $ docker rm tmpdb
   

6. Configure nginx to match your requirements.

Edit nginx/redmine.com and change <mydomain> for your domain (for instance www.redmine.com).

Edit docker-compose.yml and change <path_to_crt_file> and <path_to_key_file> to, respectively, the absolute path to your SSL certificate and the absolute path to your SSL key.

7. Use docker-compose to run production setup

    $ docker-compose up
   

8. (Optional) Edit your Dockerfile to add plugins or to edit theme (see comments).
