+  A compilation of issues and resolutions encountered during the creation and troubleshooting of operators.

+
+* Issue
+
+  Operator Controller-manager pod keeps crashlooping with OOMkilled
+
+* Resolution
+
+  Increase the memory for the controller-mananger pod by editing the operator CSV:
+
+   ````
+   resources:
+      limits:
+        cpu: 200m
+        memory: 400Mi    <------ Increased to 400Mi
+      requests:
+         cpu: 200m
+         memory: 400Mi   <------ Increased to 400Mi
+   ````
+
+* Issue
+
+  Docker image run on Openshift with the following error:
+  ````
+  exec /srv/app/entrypoint.sh: exec format error
+  ````
+* Resolution
+
+  Review the Docker image, as it may have been built on a device with an architecture that differs from that of Openshift.
+
+  ````
+  docker image inspect cloudtruth/kubetruth:1.2.2-redhat.test.2 | grep Architecture
+        “Architecture”: “arm64", 
+  ````  
+
+  Verify if the architecture of the node matches that of the Docker image.
+  ````
+  oc get node ip-####.us-west-2.compute.internal -oyaml | grep architecture
+    architecture: amd64
+  ````
