Node pod reverse DNS.

Jump to solution

Hi.

Have a new issue. The first was solved by creating a correct secret.

Now my controller pods star and get Ready, but the node pods go in to CrashLoop complaining on not able to do reverse DNS lookup.

Must the reverse maps be configured?

The problem is that the deployment with the Dell CSI Operator misses the dnsPolicy: ClusterFirstWithHostNet by default (cf. https://github.com/dell/csi-powerscale/blob/master/helm/csi-isilon/templates/node.yaml#L63).

 

To fix it you can modify the DaemonSet Isilon-node and add it :
