I've recently written a Helm chart for my application adding a redis dependency in the requirements.yaml file:

dependencies:
  - name: "redis"
    version: "~4.0.0"
    repository: "https://kubernetes-charts.storage.googleapis.com/"

I've noticed that whenever I run my helm upgrade command the redis dependency gets always reinstalled, bringing redis down all the times I just need to upgrade my application.

The command I'm running is something along the lines of helm upgrade --wait release-name ./helm-folder

Is this behaviour expected? Isn't helm supposed to only update the application pod if there hasn't been any change to the requirements.yaml/requirements.lock file?

Thanks,
