How to delete calicoctl and iptables (created by calico installation) from my k3s

Question

I have a K3s setup with calico pods [calico-node- & calico-kube-controllers-] running. On uninstalling K3s, calico pods get deleted but I see that calicoctl and iptables -S commands still running and shows data.

I want to delete calico (including calicoctl and Iptables created by calico) completely. Which commands will help me to do so ?

K3s uninstalltion command: /usr/local/bin/k3s-uninstall.sh deletes all k3s pods including calico, but calicoctl and iptables -S still works.

PS: I already tried few things -

1. Command kubectl delete -f https://raw.githubusercontent.com/aws/amazon-vpc-cni-k8s/release-1.5/config/v1.5/calico.yaml deletes the calico-node- but calico-kube-controller , calicoctl and iptables -S are still present
2. Kubectl delete commands in this que also not working for me, after executing these two commands still calicoctl and iptables -S are present

Answer 1

Calico does not provide any automatic uninstallers that I am aware of. You'll have to handle this yourself.

Answer 2

Deleting calico-Iptables:

Use calico-policy and add below lines at the end of script:

echo "Flush remaining calico iptables"
iptables-save | grep -i cali | iptables -F

echo "Delete remaining calico iptables"
iptables-save | grep -i cali | iptables -X

This will delete all calico iptables when you check with iptables -S

Note: Run this script only after uninstalling K3S.

Deleting calicoctl:

Simply run sudo rm $(which calicoctl) command, it will find and delete the calicoctl.
