DoMG

Web based docker container manager. And /etc/hosts updater.

Logic

This app will update the /etc/hosts file in realtime based on the Docker events of starting/stopping docker containers.

It needs to be running at the time the new containers are started to be able to see the docker events.

It looks at each new started container for 2 values: hostname and domainname. It will use those 2 values to provide a FQDN in the hosts file so you can access local containers by hostname instead of ip address.

Example:

Start a docker container with the hostname apache-local and domain name local-dev. DoMG will create an entry in the hosts file:

172.xx.xx.xx apache-local.local-dev

You can now access the container's port 80 via http://apache-local.local-dev/

Running

Docker-Compose

1. Create a docker-compose.yml file somewhere.
2. Put this in it:

apps:
  image: talpah/domg
  volumes:
    - /var/run/docker.sock:/var/run/docker.sock
    - /etc/hosts:/host_hosts
  hostname: containers
  domainname: domg

3. Run docker-compose up -d
4. Access http://containers.domg/

Docker Run

1. Run it directly:

docker run --rm --name containers -v /var/run/docker.sock:/var/run/docker.sock -v /etc/hosts:/host_hosts --hostname containers --domainname domg talpah/domg
