1, Create an OCP 4.3 cluster within the fixed PR.

[hui@localhost ~]$ oc get clusterversion

2, Check the default CatalogSource, OLM pods, they worked well.

The OLM pods work well. But the error message reported (message: no reconciler for source type grpc) for the catalog source is unclear and not good for readable.

[hui@localhost ~]$ cat cs-configmap.yaml

The OLM pods work well. But the error message reported (message: 'failed to get catalog config map : configmap "" not found') for the catalog source is unclear and not good for readable.



5, Create a CatalogSource object without image, address, and sourceType.

[hui@localhost ~]$ cat cs-grpc-cm.yaml 
apiVersion: operators.coreos.com/v1alpha1
kind: CatalogSource
metadata:
  name: bug-empty
  namespace: openshift-marketplace
spec:
  displayName: Jian Operators
  publisher: jian
[hui@localhost ~]$ oc create -f cs-grpc-cm.yaml 
The CatalogSource "bug-empty" is invalid: spec.sourceType: Required value

The message looks good to me.

6, Install an operator on the console, for example, etcd. But there is no csv or pod created.

[hui@localhost ~]$ oc get sub -A
NAMESPACE   NAME   PACKAGE   SOURCE                CHANNEL
default     etcd   etcd      community-operators   singlenamespace-alpha
[hui@localhost ~]$ oc get sub etcd -n default -o yaml
apiVersion: operators.coreos.com/v1alpha1
kind: Subscription
metadata:
  creationTimestamp: "2020-05-06T07:25:57Z"
  generation: 1
  name: etcd
  namespace: default
  resourceVersion: "29871"
  selfLink: /apis/operators.coreos.com/v1alpha1/namespaces/default/subscriptions/etcd
  uid: a757fb4b-3225-403c-8854-fda5232bc717
spec:
  channel: singlenamespace-alpha
  installPlanApproval: Automatic
  name: etcd
  source: community-operators
  sourceNamespace: openshift-marketplace
  startingCSV: etcdoperator.v0.9.4
[hui@localhost ~]$ oc get csv -n default 
No resources found in default namespace.
[hui@localhost ~]$ oc get pods -n default 
No resources found in default namespace.


7. Delete the catalogsource objects (grpc and configmap) created in the step 3 and 4. 
[hui@localhost ~]$ oc delete -f cs.yaml 
catalogsource.operators.coreos.com "bug-no-image" deleted
[hui@localhost ~]$ oc delete -f cs-configmap.yaml 
catalogsource.operators.coreos.com "bug-no-image-cm" deleted

8. Install an operator on the console, for example, etcd. It works well.
[hui@localhost ~]$ oc get sub -A
NAMESPACE   NAME   PACKAGE   SOURCE                CHANNEL
default     etcd   etcd      community-operators   singlenamespace-alpha
[hui@localhost ~]$ oc get csv -n default
NAME                  DISPLAY   VERSION   REPLACES              PHASE
etcdoperator.v0.9.4   etcd      0.9.4     etcdoperator.v0.9.2   Succeeded
[hui@localhost ~]$ oc get pod -n default
NAME                             READY   STATUS    RESTARTS   AGE
etcd-operator-65c7948765-lfhsl   3/3     Running   0          77s



In summary, there are still two issues. 
1. The error message reported is unclear. 
2. The csv and ip for the sub etcd can not be created because of the incorrect catalogsource (grpc or configmap without address or image). Delete the incorrect catalogsource, the etcd csv and ip works well.

> 1. The error message reported is unclear. 

Backported a change from 4.4 that improves the status messages. Thanks!

> 2. The csv and ip for the sub etcd can not be created because of the incorrect catalogsource (grpc or configmap without address or image). Delete the incorrect catalogsource, the etcd csv and ip works well.

This is expected behavior. Resources should not be generated for a subscription if the catalog operator is unable to communicate with all relevant catalog sources. This prevents situations where an out-of-date (and potentially vulnerable) operator is installed as a dependency because the catalog source containing a newer version is not healthy.
