deploy-heketi pod fails when firewalld is active #471

Open rwsu opened 6 years ago

rwsu commented 6 years ago

gk-deploy times out waiting for the deploy-heketi pod to start when I have firewalld running. If firewalld is disabled, gk-deploy completes successfully.

My environment is

@rwsu Hi! Sorry for the delay.

What did you use for your kube deployment and networking? I'm seeing a lot of issues with that when searching for your particular error message:

@jarrpa I used kubeadm to create the cluster and Weave Net as the CNI.

Did you check through any of the hits in that search? Anything you've determined is not a problem?
