Cleanup host added as custom to Rancher 2.0

cleanup.sh

#!/bin/sh
# OUTDATED: please refer to the link below for the latest version:

docker rm -f $(docker ps -qa)
docker volume rm $(docker volume ls -q)
cleanupdirs="/var/lib/etcd /etc/kubernetes /etc/cni /opt/cni /var/lib/cni /var/run/calico /opt/rke"
for dir in $cleanupdirs; do
  echo "Removing $dir"
  rm -rf $dir
done

When installing rancher-agent on the same host for testing purposes the cluster would not run properly until I also removed all data from /opt/rancher, perhaps it was only one of the three dirs:

root@rancher:~# ls /opt/rancher
certs-cache  k3s  management-state

Thanks !
ros should have a clean function. Or reinstall from cloud-config...

Will this unregister the node from the cluster too ?

saved me a bunch of time, tyvm!

Are you shure it's /var/run/calico and not /var/lib/calico?

@HoffmannP This gist is outdated, I updated the code with a link to the updated version.
