I want to use auth token to fetch image from docker-hub account to avoid rate limit but I do not want to pass whole config.yaml as a secret because I am using helm chart and providing configmap with helm template, now my question is that how we can just define auth thingy using k8s-secret or with envsubst to subsitute its values using ENV variable in k8s job.
And do I need to install envsubst explicitly to get it work.
