Description

What would you like to be added?

After receiving the instructions on how to setup a kubernetes test harness on Antithesis, we should do the following:

  • Add a separate setup for Kubernetes in Antithesis directory.
  • Confirm that etcd-operator works (i.e. can be used to setup the etcd test cluster).
  • Document the instructions how to setup the etcd cluster on Kind.
  • Antithesis has local validator for Kubernetes, so we should find a way to integrate with it and then document.

Research direction
The issue requires setting up a Kubernetes test harness for Antithesis. Look at the existing Antithesis directory in the repository (likely under /test or /hack) for patterns. Investigate the etcd operator repository for how to deploy etcd clusters on Kubernetes. Document steps for setting up Kind cluster and integrating with Antithesis's local validator.
