Let's follow [the official docs](https://docs.drone.io/server/provider/gitea/) in order to generate a OAuth2 application, which is necessary for Drone integration.

Don't forget to have proper docker labels on nodes, as explain [here]({{< ref "04-build-your-own-docker-swarm-cluster-part-3#add-environment-labels" >}}), otherwise docker runner will not run because of `node.labels.environment == build`.

It's time to go to <https://drone.sw.okami101.io/> and generate your first Drone account through OAuth2 from Gitea. You should be properly redirected to Gitea, where you'll just have to authorize Drone application.
