The previous configuration exposes the following issue:
```
Jul 23 12:41:43 worker-2 kubelet[29002]: #011For verbose messaging see aws.Config.CredentialsChainVerboseErrors
Jul 23 12:41:43 worker-2 kubelet[29002]: E0723 12:41:43.068772 29002 remote_runtime.go:81] Version from runtime service failed: rpc error: code = Unimplemented desc = unknown service runtime.v1alpha2.RuntimeService

Jul 23 12:41:43 worker-2 systemd[1]: kubelet.service: Failed with result 'exit-code'.
```
otherwise using the default config and restarting containerd and the kubelet service seems to come back clean.
This is:
```
No LSB modules are available.
