A senior infrastructure screen of conversation questions:

  1. How do you bring up a new compute cluster in a new cloud account, and deploy Kubernetes there for the first time?
  2. How do virtual machines work underneath (hypervisors, hardware virtualization)?
  3. In CI/CD, how is a container image built, pushed to a registry and pulled onto nodes?
  4. Concurrency basics.
  5. What Kubernetes operators and custom resource definitions are for.
