Guide to getting Drydock

Quick Start: Land Revisions

Quick start guide to getting "Land Revision" working in Differential. For a more detailed guide, see Drydock User Guide: Repository Automation.

Choose a repository you want to enable "Land Revision" for. We'll call this Repository X.

You need to configure a staging area for this repository if you haven't already. You can do this in Diffusion in Edit RepositoryEdit Staging. We'll call this Staging Area Y.

Choose or create a host you want to run merges on. We'll call this automation001. For example, you might bring up a new host in EC2 and label it You can use an existing host if you prefer.

Create a user account on the host, or choose an existing user account. This is the user that merges will execute under: Drydock will connect to it and run a bunch of git commands, then ultimately run git push. We'll call this user builder.

Install git, hg or svn if you haven't already and set up private keys for builder so it can pull and push any repositories you want to operate on.

If your repository and/or staging area are hosted in Phabricator, you may want to create a corresponding bot account so you can add keys and give it permissions.

At this point you should be able to ssh builder@automation001 to connect to the host, and get a normal shell. You should be able to git clone ... from Repository X and from Staging Area Y, and git push to Repository X. If you can't, configure things so you can.

Now, create a host blueprint for the host. You can find a more detailed walkthrough in Drydock Blueprints: Hosts. Briefly:

  • Create an Almanac device for the host. This should have the IP address and port for your host.
  • Create an Almanac service bound to the device. This should be a Drydock resource pool service and have a binding to the IP from the previous step.
  • Create a Drydock host blueprint which uses the service from the previous step. It should be configured with an SSH private key that can be used to connect to builder@automation001.

Then, create a new working copy blueprint which uses the host blueprint you just made. You can find a more detailed walkthrough in Drydock Blueprints: Working Copies. Authorize the working copy blueprint to use the host blueprint.

Finally, configure repository automation for Repository X: Edit RepositoryEdit Automation. Provide the working copy blueprint from the previous step. Authorize the repository to use the working copy blueprint.

After you save changes, click Test Configuration to test that things are working properly.

The "Land Revision" action should now be available on revisions for this repository.
