+#### 3. Deploy development version to K8s cluster
+
+Deployment provides a good environment for:
+- Final testing in a real world scenario
+- Run the final version until included in a release
+
+> [!Note]
+> Make sure to do the build on the architecture you will be running it.
+> For example, don't build in Apple Silicon if your cluster runs in amd64.
+
+
+1. Login to your github container registry
+```bash
+docker login ghcr.io

+
+2. Compile and push to your github container registry.
