how to delete/remove calico cni from my kubernetes cluster

Question

I have installed my kubernetes cluster(1master, 3worker)in the digital ocean.
The problem is I installed both flannel and calico in this cluster.
I want to remove the calico completely from my cluster or is it ok to have multiple CNI?

Solution

Use following two commands to remove calico from your node:

kubectl delete -f https://docs.projectcalico.org/v3.3/getting-started/kubernetes/installation/hosted/rbac-kdd.yaml
kubectl delete -f https://docs.projectcalico.org/v3.3/getting-started/kubernetes/installation/hosted/kubernetes-datastore/calico-networking/1.7/calico.yaml

How did you add calico to the cluster or it came by default with cluster deployment?

[shreyas]

do we need to replace v3.3 in the URL with our installed version?

Did I miss where the question indicates they use Ansible?

@CashIsClay that's right, you miss the fact that this question is edited in Dec 19 2019, and my answer was Dec 4 2018.

@coolinuxoid the revision of the edit only shows that or is it ok to have multiple CNI? was added.. no mention of Ansible

@Coffeeholic not sure what you are trying to achieve but I am sure that question was with Ansible related. I remember this very well

@PrafullLadha-: I tried your Kubectl delete commands but I am not able to delete calicoctl . The command and calico pods are still up. My calico version is: Client Version: v3.19.1 Git commit: 6fc0db96
