docker-compose-semaphore

A set of dockerized apps to support Semaphore, a web application for Ansible.

There are three applications:

• Apache httpd - to deal with SSL. (HTTPS)
• Semaphore - the application itself.
• MySQL - to store persistent data

Overview of the environment

+-------+     +-----------+     +-------+
| httpd | --> | semaphore | --> | mysql |

Running the application

In order to run this application, run these commands:

git clone https://github.com/robertdebock/docker-compose-semaphore.git
cd docker-compose-semaphore
docker-compose up

When started, press CTRL+C or "docker-compose stop" to (temporarily) stop it. When using "docker-compose start", all persistent data will be in tact.

Login with the default username / password combination:

• username: semaphore
• password: semaphore

Customizing the application

You may want to customize variables.env, where you can add Apache HTTPD settings like so:

SERVERNAME=semaphore.meinit.nl:443
SERVERADMIN=robert@meinit.nl
SSL_COUNTRY=NL
SSL_STATE=UTRECHT
SSL_LOCATION=Breukelen
SSL_ORGANIZATION=Me in IT Consultancy
SSL_ORGANIZATIONAL_UNIT=IT Department
SSL_COMMONNAME=semaphore.meinit.nl

Managing the application

Two scripts have been added:

• scripts/backup.sh - Backs up: mysql, /tmp and /root/.ssh/
• scripts/restore.sh - Restores the backup.

Restoring is only required when the volumes have been removed, so either because "docker-compose down" was issued of when the Docker engine has been changed.
