=== Clean State === | |||
Sometimes it helps to have a clean state on all instances: | |||
* comment kubernetes-related code in <code>configuration.nix</code> | |||
* <code>nixos-rebuild switch</code> | |||
* clean up filesystem | |||
** <code>rm -rf /var/lib/kubernetes/ /var/lib/etcd/ /var/lib/cfssl/ /var/lib/kubelet/</code> | |||
** <code>rm -rf /etc/kube-flannel/ /etc/kubernetes/</code> | |||
* uncomment kubernetes-related code again | |||
* <code>nixos-rebuild switch</code> | |||
== Tooling == | |||
