Building images and storing them inside Gitea's built-in registry (`://example.com`) ensures that you can decouple your actual build step from the live deployment server. It also provides a snapshot history of your homelab services.

1. Update your `docker-compose.yml` to point to Gitea [[1](https://forum.gitea.com/t/strange-behavior-when-upgrading-to-1-22-1-from-1-15-9/9664)]

Change your local container configuration so that instead of building in place, it pulls a tagged image hosted right inside your Gitea instance:

	services:
	  custom-app:
	    # Point the image path directly to your self-hosted Gitea registry URL
	    image: gitea.homelab.local/${{ gitea.repository_owner }}/custom-app:latest
	    ports:
	      - "8080:80"

2. Create the Build & Push Job Step

Add this block right before your deployment phase. Gitea Actions automatically exposes a temporary validation token (`${{ gitea.token }}`) for every run, which means you don't need to manually configure registry usernames or passwords in your secrets dashboard!
