Operations grimoire/Dwellers to DevCentral

This document explains how to communicate with DevCentral from the Docker host.

If you're interested to communicate between DevCentral and a Docker container, see Git operations in production containers

Rewrite remotes

ssh://vcs@devcentral.nasqueron.org:5022/diffusion/DJENKINSSLAVES/docker-jenkins-slaves.git

becomes:

ssh://vcs@devcentral.docker.ulubis/diffusion/DJENKINSSLAVES/docker-jenkins-slaves.git

See https://devcentral.nasqueron.org/T958 for discussion about DNS.

Arcanist

arc is a wrapper to run nasqueron/arcanist container.

To use it, create a ~/.arc folder with:

1. a arcrc file for your arc configuration
2. a gitconfig file for your Git configuration
3. a ssh folder with a dedicated key for Dwellers to Phabricator instances (mkdir -p ~/.arc/ssh && ssh-keygen -t ed25519 ~/.arc/ssh/id_ed25519)

For example:

.
├── arcrc
├── gitconfig
└── ssh
    ├── id_ed25519
    ├── id_ed25519.pub
    └── known_hosts

That folder content will be passed as volumes to the container. In the example, known_hosts has been added by ssh client inside the container.

Don't use symbolic links (hard links are okay), they wouldn't resolve when passed as a volume to the container.

To check if all works as expected: ssh vcs@devcentral.docker.ulubis
