Appendix - Calico Installation and Verification

To Install Calico networking agents on all the Instances

kubectl apply -f https://docs.projectcalico.org/v3.10/manifests/calico.yaml

To Install Calico controller

networkandcode@k8s-master-0:~$ kubectl apply -f https://docs.projectcalico.org/v3.10/manifests/calicoctl.yaml
serviceaccount/calicoctl created
pod/calicoctl created
clusterrole.rbac.authorization.k8s.io/calicoctl created
clusterrolebinding.rbac.authorization.k8s.io/calicoctl created

To Check the profiles

networkandcode@k8s-master-0:~$ kubectl exec -it calicoctl -n kube-system -- /calicoctl get profiles -o wide
