+- Add the entry `registry.demo` pointing to your cluster in your local `/etc/hosts` and on each node of your cluster
+- on each node, create the file `/etc/rancher/k3s/registries.yaml` with this content:
+```
+mirrors:
+  registry.demo:
+    endpoint:
+      - "http://registry.demo/v2/"
+```
+- restart k3s
+
+- build the demo images
+```
+cd demo-flask
