Can't set up CaaS charm with no ports

[Kenneth Koski]

I am trying to write a charm that doesn't require having any ports open, and I'm required to add a dummy port, otherwise I get this error:

    creating or updating service for foo: Service "foo" is invalid: spec.ports: Required value

I don't need a Service resource created for this charm, since there's no open ports anyways. Would it be possible to just not set up the Service if no ports are defined?

It's already possible to not create the k8s service by adding this to your podspec yaml:

omitServiceFrontend: true

Can you see if this works for you?

Thanks for the response, and that was close to working, though now I get this error:

    kubernetes service is required when using storage

This is despite the charm not using storage as defined in the `storage:` key in `metadata.yaml`, though it is making files available to the pod via the `files: {...}` section of `pod_spec_set`.

This sounds like it might be another case where if you set a port we'd flip
this to false and otherwise default to this as true vs asking the user to
tie together the different config items correctly,.
