Installation of Knative-GCP v0.22.0 does not work due to inaccessible images

[meteatamel]

Describe the bug
I tried to install knative-gcp v0.22.0 in a cluster that already has Knative Serving and Eventing installed with the following script I have here.

Everything seemed successful but when I do look at pods, I see ImagePullBackOff:

kubectl get pods -n cloud-run-events
NAME                          READY   STATUS             RESTARTS   AGE
controller-78dc7b9568-fb87m   0/1     ImagePullBackOff   0          20m
webhook-74847d744f-79ppf      0/1     ImagePullBackOff   0          20m

When I get the pods, this is what I see:

kubectl get pod controller-78dc7b9568-fb87m -n cloud-run-events -oyaml
state:
      waiting:
        message: Back-off pulling image "gcr.io/knative-gcp/github.com/google/knative-gcp/cmd/controller@sha256:0ec02ca2a960b4515829531132eeb9e8e115773e912d9b9fed1e1d9a8e45fd94"
        reason: ImagePullBackOff

kubectl get pod webhook-74847d744f-79ppf -n cloud-run-events -oyaml
    state:
      waiting:

When I try Docker to pull these images, they are not accessible:

docker pull gcr.io/knative-gcp/github.com/google/knative-gcp/cmd/controller@sha256:0ec02ca2a960b4515829531132eeb9e8e115773e912d9b9fed1e1d9a8e45fd94

Expected behavior
Pods start successfully.

This has been fixed with a change to GCR permissions
