Hi CKAers,
I have deployed a 3 (1 master and 2 worker) node cluster .
I have used flannel as networking add-on and used the below command
kubectl apply -f <https://raw.githubusercontent.com/coreos/flannel/master/Documentation/kube-flannel.yml>
But pods are not able to reach each other :
kube-system pods are in running state.
Any help will be greatly appreciated

ub[email protected]:~$ kubectl get po -n kube-system

Satyam Sareen:
Thankyou @unnivkn

Satyam Sareen:
it was an issue with my security group, flannel uses different ports than weave

Satyam Sareen:
so had create new sg rules

unnivkn:
okie… so your k8s cluster is on cloud ?

Satyam Sareen:
yup, ec2 machines on aws
