MantisBT is an open source issue tracker that provides a delicate balance between simplicity and power.

Example docker-compose.yml

The examples suppose you will have the data for your containers in /srv/mantis. Adapt for your server.

        links:
          - mysql
          - phpmyadmin
        restart: always

mysql:

You can use mysql/postgres instead of mariadb.

postgres:
  image: postgres:latest
  environment:
    - POSTGRES_USER=root
    - POSTGRES_PASSWORD=root
    - POSTGRES_DB=bugtracker
  restart: always
  volumes:
    - /srv/mantis/pgsql:/var/lib/postgresql/data
