Describe the bug

Using Volume Mounter trait results in Kubernetes Service creation failure

OAM yaml files used

Component

apiVersion: core.oam.dev/v1alpha1
kind: ComponentSchematic
metadata:
  name: emphemeral-vol-example
spec:
  workloadType: core.oam.dev/v1alpha1.Server
  containers:
    - name: server
      image: nginx:latest
      resources:
        volumes:
          - name: emphemeral-vol
            mountPath: /emphemeral-vol
            disk:
              required: "50M"
              ephemeral: true

App config

apiVersion: core.oam.dev/v1alpha1
kind: ApplicationConfiguration
metadata:
  name: example-server-with-volume
spec:
  components:
    - componentName: emphemeral-vol-example
      instanceName: emphemeral-vol-example1
      traits:
        - name: volume-mounter
          properties:
            volumeName: emphemeral-vol
            storageClass: default

What happened:

Kubernetes Service was not created - kubectl get svc did not contain the expected service and ComponentSchematic reported failure status (for Service):

kubectl get applicationconfiguration.core.oam.dev/example-server-with-volume -o yaml returned

status:
  components:
    emphemeral-vol-example:
      deployment/emphemeral-vol-example1: running
      persistentvolumeclaim/emphemeral-vol: Bound
      service/emphemeral-vol-example1: ApiError NotFound ("services \"emphemeral-vol-example1\"
        not found")
  phase: synced

Notice service/emphemeral-vol-example1: ApiError NotFound ("services \"emphemeral-vol-example1\" not found")

What you expected to happen:

Service to be created

Relevant screenshots:

How to reproduce it (as minimally and precisely as possible):

Create component and app config (pasted above)

Anything else we need to know:

The Deployment was created (and so did the other kubernetes objects). Service creation failed

I was able to reproduce this

rudr::workload_type::workload_builder] Not attaching service to pod with n
o container ports.

if you don't sepecify a containerPort in your component spec, rudr will skip service creation
I agree that "Not Found" status is confusing though. I'll try to make it look friendly

@macolso this can be relabeled "enhancement"

Ah I see! Thanks @zhxu2
