This page outlines ways to troubleshoot your Arc deployments
The most common issue while deploying is not having a cluster with capacity enough to support the namespaces and workloads needed for Arc
For setup instructions on how to setup kubectl see the following article
How to verify the pods are running the workload
Go to the command line or the cloud console / cloud shell and run the following commands for the namespace you setup the extensions on
kubectl get pods -n “namespace” -o wide
IF you see any pods that are not in the “ready” state, which would have a state of 2/3 or 0/2, run this command on the name that is not starting
kubectl describe pod “name-from-above-command” -n “namespace”
This will give you a detailed reason why the service is unable to be deployed
