Garnix

Garnix is a CI service for nixified, flake-based github repos.

Running Garnix locally in VMs

You can spin up a couple of qemu VMs that provide a full Garnix deployment with:

nix run -L .#examples_spinUpVms

This will use nixos-compose. If you run:

nixos-compose tap
nixos-compose status

You should then be able to point your browser to the ip address of the exampleGarnixServer to see the hosted ci.

And there's an admin page on /garnix-admin that is useful for some development tasks.

Setting up a GitHub app

You will need a github app for Garnix to work, both for production and for testing. On the /garnix-admin page you can create one by pressing the 'Submit to GitHub' button. That will give you a bunch of credentials that you'll have to put into the /secrets/dev.yaml file by running

sops edit secrets/dev.yaml

Then you have to enable your new GitHub app on a repo that you want to build through the GitHub ui. Finally, you can submit a test build, with something like this:

curl -v \
  -XPOST \
  http://$(nixos-compose ip exampleGarnixServer)/api/build/submit \
  -H 'Content-Type: application/json' \
  -d '{ "owner": "garnix-io", "repo": "comment", "testCommit": "8b2b57d91dd1f4d094bb944a0a0ef65319a5663f" }'

And then you can see the build under /repo/garnix-io/comment, for example.

Developing the frontend

You can run the frontend in development mode against a backend in a VM like this:

nixos-compose up -v
cd frontend
npm run dev

Then point your browser to localhost:3000.
