Fixed In Version:
Doc Type: Bug Fix
Doc Text:
Cause: Slow localhost resolution in operator index pods. Consequence: Operator index pods restart due to failing liveness probes. Fix: Operator index pods write default nsswitch.conf if not present to prefer local files over DNS resolution for localhost. Result: Operator index pods resolve localhost quickly enough for liveness probes to succeed consistently.

OCP version: 4.3.0-0.nightly-2020-05-27-224458
[root@preserve-olm-env 1816185]# oc exec catalog-operator-7558695ff7-qmv7s -n openshift-operator-lifecycle-manager -- olm --version
OLM version: 0.13.0
git commit: 3740fa3a8aa571ba4ee1f048561d674d4fc6c2d3

Platform: azure

Steps to test:
1. Create the community catalog source on platform azure other than aws

cat <<EOF > community-operator-catalog.yaml
apiVersion: operators.coreos.com/v1alpha1
kind: CatalogSource
metadata:
  name: community-operator-catalog
  namespace: openshift-marketplace
spec:
  displayName: Community Operator Catalog
  sourceType: grpc
  image: docker.io/wangzheng422/operator-catalog:community-2020-02-29
  publisher: Community
EOF
oc create -f community-operator-catalog.yaml


2. Check the catalogsource and pod status.

[root@preserve-olm-env 1816185]# oc get catsrc -n openshift-marketplace
NAME                         DISPLAY                      TYPE   PUBLISHER   AGE
community-operator-catalog   Community Operator Catalog   grpc   Community   24m
[root@preserve-olm-env 1816185]# oc get pod -n openshift-marketplace
NAME                                    READY   STATUS    RESTARTS   AGE
community-operator-catalog-zc2lz        1/1     Running   0          24m

The community operator catalog pod is running. Verify the bug.
