whoami pods unable to start

[Bastien Gounon]

Hello,
We're running whoami for testing purposes on our K8S Cluster, using latest DockerHub image.
We're seeing a new issue today that we didn't have before.
Pods fail to start with the following logs:

Starting up on port tcp://10.100.7.29:80
2021/12/03 16:44:43 listen tcp: address :tcp://10.100.7.29:80: too many colons in address

I see there has been a new release today, is it related ?
I can reproduce at will by simply pushing the following configuration to a K8S cluster:

kind: Deployment
apiVersion: apps/v1
metadata:
  name: whoami
  labels:
    app: traefiklabs
    name: whoami
spec:
  replicas: 2
  selector:

      app: traefiklabs
      task: whoami

        task: whoami

spec:

    - host: example.com
      http:
        paths:
          - path: /
            backend:
              serviceName: whoami
              servicePort: 80

Edit: using image traefik/whoami:v1.6.1 fixes the issue

Hello,

The problem is related to the fact the port flag is filled by an address instead of a port.

# version v1.5.0
$ whoami -port tcp://10.100.7.29:80
Starting up on port tcp://10.100.7.29:80
2021/12/03 18:32:25 listen tcp: address :tcp://10.100.7.29:80: too many colons in address
exit status 1

# version v1.6.0
$ whoami -port tcp://10.100.7.29:80
Starting up on port tcp://10.100.7.29:80
2021/12/03 18:31:42 listen tcp: address :tcp://10.100.7.29:80: too many colons in address
exit status 1

# version v1.7.0
$ whoami -port tcp://10.100.7.29:80
Starting up on port tcp://10.100.7.29:80
2021/12/03 18:34:04 listen tcp: address :tcp://10.100.7.29:80: too many colons in address
exit status 1

Maybe you have an env var called WHOAMI_PORT with the value tcp://10.100.7.29:80

It seems related to a k8s behavior.
