[DRBD-user] STORK driver source code

[kvaps]

Hi Christoph,

> You are using Pireaus operator to deploy LINSTOR, right?

No we're using https://github.com/kvaps/kube-linstor and I'm going to add
support of your stork plugin for that.

I'm little skeptical about using operator approach for anything else
besides configuration or managing difficult application lifecycle :)
Instead, I like when application can be simple deployed by simple templated
manifests. Kubernetes already have all needed controllers for managing it.

report.

I'm sure that adding support for the same environment variables like for
linstor-csi is the easiest and better way, ideally I'd like to have:

      env:
        - name: LINSTOR_IP
          value: https://linstor-controller:3371
        - name: LS_USER_CERTIFICATE
          valueFrom:
            secretKeyRef:
              key: tls.crt
              name: linstor-client-tls
        - name: LS_USER_KEY
          valueFrom:
            secretKeyRef:
              key: tls.key
              name: linstor-client-tls
        - name: LS_ROOT_CA
          valueFrom:
            secretKeyRef:
              key: ca.crt
              name: linstor-client-tls

And of course do not hardcode driver with the piraeus-operator. it's better
to keep the things loosely coupled with each other, and components
replaceable.

Got it! Sorry, this branch had no these changes at this weekend :)
