`eval $(minikube docker-env --unset)` switches back to the local daemon
afterwards. Since minikube is itself a Docker container, `minikube ssh` opens a
shell inside it for low-level inspection, checking the loaded images or adding
a hostPath mount for example.
+minikube 1.39 and later default to containerd, which does not support building
images through `minikube docker-env`. Building through `docker-env` needs a
cluster on the Docker runtime, as used by the end-to-end tests, and minikube
cannot change the runtime of an existing cluster. The recommended approach is
to remove the existing cluster with `minikube delete` and to start a new one
with:
+
+```bash
+minikube start --kubernetes-version=v1.28.0 --container-runtime=docker

### Installing the Operator Locally
The admission webhook runs by default and needs cert-manager for its TLS
certificate, installed once per cluster:
