+## Use Minikube as Alternative to KinD
+
+Build the docker images as described above (section 5.1). Then, instead of
+moving on to section 5.2, do the following:
+
+0. `alias minikube='minikube -p mvd'`
+1. `alias kubectl='minikube kubectl --'`
+2. `minikube start`
+3. `minikube addons enable ingress`
+4. Wait for the ingress controller to become available:
+ ```
+ kubectl wait --namespace ingress-nginx \
+ --for=condition=ready pod \
+ --selector=app.kubernetes.io/component=controller \
+ --timeout=90s
+ ```
+5. Forward the local port 80 to the ingress controller:
+ `sudo ssh -i $(minikube ssh-key) docker@$(minikube ip) -L 80:localhost:80`
+6. Load the images:
+ `minikube image load controlplane:latest dataplane:latest identity-hub:latest catalog-server:latest sts:latest`
+
+Now you can go on with starting the pods with `terraform init`, `terraform apply` etc. (see above, section 5.2).
