Yes, I meant pod. I was editing the dremio.conf file with the changes I mentioned and then did a helm delete, then a helm install --wait dremio.
Everything worked but only the http endpoints were available.
I have since solved this problem by modifying the ELB created by k8 to use map https traffic to the internal service port for dremio. This is actually a better solution for me than configuring the jks in dremio anyway.
