# 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)
