Your App Is Alive

A SkillsCast for this session is not available.

I’ll start with brief overview of the pieces of Kubernetes needed (rc, manifest, etc) and a running cluster as a prerequisite. I’ll show off a simple go app with a web server. I’ll add a /healthz endpoint, build and push my image to a registry. I’ll reference my new image in the manifest. I will then deploy my manifest into my cluster to create a pod. I’ll show the audience how to talk to my /healthz endpoint. I’ll then go back and introduce the liveness probe and put the liveness probe definition into the manifest, delete my existing rc, re-deploy my new manifest, and show off the logs for the pod confirming that the health check is being performed at the specified intervals.
