Error installing Companion server on Kubernetes

Hi, I am installing Companion server on Kubernetes as mentioned here:

But, I am running into the following errors in the pod after it starts and it keeps on forcing a restart going on a crashloop. Any help is greatly appreciated. Thanks.

Fixed the issue by setting the env variable: COMPANION_PORT=3020
If that is not set, it is taking the default port from kubernetes as tcp://xx.xx.xx.xx:3020
