+### Image rebuild and redeployment
+
+To avoid a continuos redeployment of the whole setup, there is always the manual process of building 
+the `admin-ui` image 
+
+```shell
+$ SKAFFOLD_DEFAULT_REPO=localhost:32000 skaffold build --push=true --cache-artifacts=false
+Generating tags...
+ - identity-platform-admin-ui -> localhost:32000/identity-platform-admin-ui:v1.5.0-181-g1107165-dirty

 ### OpenFGA initialization
 
 The Admin Service comes up with authorization disabled (see `AUTHORIZATION_ENABLED` env var), The env vars `OPENFGA_AUTHORIZATION_MODEL_ID` and `OPENFGA_STORE_ID` which are needed for the correct functioning of the RBAC APIs get set by the job `admin-ui-openfga-setup`, after this has completed a developer is supposed to bounce the deployment to get the application to source the new env vars
