- @& P( ~0 k0 b" _: _The reset process does not clean CNI configuration. To do so, you must remove /etc/cni/net.d
& l: f0 Q' k* s! V6 S* ?
The reset process does not reset or clean up iptables rules or IPVS tables.
If you wish to reset iptables, you must do so manually by using the "iptables" command.
+ g  ~( E2 ~% x/ m# n
$ C! V* x4 D+ f5 Q- \If your cluster was setup to utilize IPVS, run ipvsadm --clear (or similar)
to reset your system's IPVS tables.

The reset process does not clean your kubeconfig files and you must remove them manually.
Please, check the contents of the $HOME/.kube/config file.
