You create an Azure Red Hat OpenShift cluster, and minutes later, you notice something interesting in the managed resource group: two storage accounts with cryptic names like cluster1a2b3c4d5e and imageregistry1a2b3c4d5e.
What are they for? Why two? And what happens if you accidentally delete one?
You open a shell inside a pod, run ping 8.8.8.8, and nothing happens. Silence.
Then you run curl https://www.microsoft.com and it succeeds immediately.
DNS resolution also works normally.
So why does ping fail?
Welcome to "Tools of the Trade" - a series where we share the tools and workflows that help us work more effectively. In this first post, I'll show you how I manage multiple AKS clusters without losing track of which cluster I'm working on. If you've ever accidentally deployed to the wrong cluster, this one's for you.
