Auth knative throws RevisionMissing error when setting up revision about vswarm

Your logs (the section called Logs do not contain the error message. Is the error that you observe is as follows?

  Container failed with: Traceback (most recent call last):

    File "/app/server.py", line 13, in <module>
      import helloworld_pb2
  ModuleNotFoundError: No module named 'helloworld_pb2'

if so, it must be reproducible with docker compose, it has nothing to do with Knative. Please double check if you run the same docker image.

So the first error is

auth-python   http://auth-python.default.192.168.1.240.sslip.io                      10m     0 OK / 3     False   RevisionMissing : Configuration "auth-python" does not have any ready Revision.

which does not give a lot of info. Hence I ran kubectl get revision auth-python-00001 --output yaml to give me the above mentioned output, for some more info about what's going on.

    File "/app/server.py", line 13, in <module>
      import helloworld_pb2
  ModuleNotFoundError: No module named 'helloworld_pb2'

if so, it must be reproducible with docker compose, it has nothing to do with Knative. Please double check if you run the same docker image.

I did that again (build, push, pull), but it still didn't work.

I actually checked the port number in knative configuration, and that was incorrect. So now the knative service sets up properly but the invoker isn't giving results like the local docker build does, so it's half-solved for now.

please get to the bottom of the ModuleNotFoundError: No module named 'helloworld_pb2' problem, some of your assumptions do not stand. instead of docker-compose you can just use docker interactively and inspect the files, etc. Also, k8s allows to access the shell of a running container, you can attach to it interactively and check. If you cannot find how to do it online, please let me know.

also, I wonder if kn service apply -f ./knative_yamls/auth-python.yaml returns an error.

[harshitgarg22]

So, I realized I was running the invoker with port 50051 like required in docker instead of 80 as specified in the docs.
It's running fine now, and I don't get the helloworld_pb2 error either. It being an old docker image and me not noticing seems to be the case.
I will check k8s shell access to see if the issue is still there.

kn service apply -f ./knative_yamls/auth-python.yaml gives

So this should be fine, although I'm not sure what Ingress has not yet been reconciled means.
