We have set up a native kubernetes cluster on bare metal server. But when I tried to install Noobaa in it its giving timeout error in the logs of noobaa-operator pod

noobaa-operator pod log time="2020-11-03T07:06:56Z" level=info msg="CLI version: 2.3.0\n" time="2020-11-03T07:06:56Z" level=info msg="noobaa-image: noobaa/noobaa-core:5.5.0\n" time="2020-11-03T07:06:56Z" level=info msg="operator-image: noobaa/noobaa-operator:2.3.0\n" time="2020-11-03T07:07:26Z" level=fatal msg="Failed to become leader: Get \"https://10.96.0.1:443/api?timeout=32s\": dial tcp 10.96.0.1:443: i/o timeout"

@NupurBharati Thanks for the information! So the error is:

Failed to become leader: Get \"https://10.96.0.1:443/api?timeout=32s\": dial tcp 10.96.0.1:443: i/o timeout

Which kubernetes environment are you using? We are not harcoding these IP's so the api server IP must be coming from the environment to the client-go SDK. You might be able to understand more by running a separate pod/container and check how kubectl cluster-info resolves the api server.

NupurBharati commented 3 years ago

@guymguym Thanks for the response. Output for the kubectl cluster-info

Version of kubernetes - 19.2

guymguym commented 3 years ago

@NupurBharati Thanks for the info! Is this cluster-info ^ running from inside a pod or from your user env? Because the operator is trying to reach the api server at 10.96.0.1:443 and your kubectl uses 10.95.241.103:6443 which could be the external address.

Next question I would try to answer is if the api-server is accessible from the noobaa-operator pod. One way to test this is to manually patch the noobaa-operator deployment and add a sleep before running the process, so that we can have time to run our manual checks, something like this - I haven't tested it so it might require some debugging:

kubectl patch deployment noobaa-operator --patch '{"spec":{"template":{"spec":{"containers":[{"name":"noobaa-operator", "command":["bash", "-x", "-c", "while true; sleep 60; done"]}] }}}}'

and try to get to the api-server like this:

$ kubectl exec deploy/noobaa-operator -- env | grep KUBERNETES_SERVICE
KUBERNETES_SERVICE_PORT_HTTPS=443
KUBERNETES_SERVICE_PORT=443
KUBERNETES_SERVICE_HOST=172.30.0.1

$ kubectl exec deploy/noobaa-operator -- curl -s --cacert /var/run/secrets/kubernetes.io/serviceaccount/ca.crt https://172.30.0.1:443

@rkomandu So the operator cannot access the api server. Did you change anything regarding the service account / role / cluster role / scc? I would start by comparing those to another deployment that works. also noobaa operator status should show you those resources names and if they exist on the cluster, but it does not check their content is matching the expected, and you can check manually if you get noobaa operator yaml and check the ServiceAccount, Role, RoleBinding, ClusterRole, ClusterRoleBinding. Hope this helps.

Nothing on the Noobaa front...

on the yaml, all above are Exists as well.. may be something is still missing to check.. All the noobaa and noobaa-endpoint are present for the noobaa-operator-yaml.txt
