+# Exercise — Monokube static pods
+
+- We want to run a very basic Kubernetes cluster by starting only:
+
+  - kubelet 
+
+  - a container engine (e.g. Docker)
+
+- The other components (control plane and otherwise) should be started with:
+
+  - static pods
+
+  - "classic" manifests loaded with e.g. `kubectl apply`
+
+- This should be done with the "monokube" VM
+
+  (which has Docker and kubelet 1.19 binaries available)
+
+---
+
+## Images to use
+
+Here are some suggestions of images:
+
+- etcd → `quay.io/coreos/etcd:vX.Y.Z`
+
+- Kubernetes components → `registry.k8s.io/kube-XXX:vX.Y.Z`
+
+  (where `XXX` = `apiserver`, `scheduler`, `controller-manager`)
+
+To know which versions to use, check the version of the binaries installed on the `monokube` VM, and use the same ones.
+
+See next slide for more hints!
+
+---
+
+## Inventory
+
+We'll need to run:
+
+- kubelet (with the flag for static pod manifests)
+
+- Docker
+
+- static pods for control plane components
+
+  (suggestion: use `hostNetwork`)
+
+- static pod or DaemonSet for `kube-proxy`
+
+  (will require a privileged security context)
