Kubernetes Cron Jobs: Dreams Really Do Come True

Abstract I worked for a large company with several hundred cron jobs running on two systems. Managing these jobs was cumbersome. Resource use during peak times brought things to a halt. Imagine what it was like when systems were down! In this talk, we discuss Kubernetes’ killer feature: Cron Jobs. Description Kubernetes, Jobs, and Cron Jobs What is Kubernetes?

Kubernetes: Cron Jobs

Kubernetes provides high-availability by design. It’s pretty awesome the possibilities that exist given this capability. Need a web server to constantly run? Build a container and throw it in the Kubernetes cluster. Need a service available all the time? [Read More]

The responsibilities are right in line with what I’m trying to do in Detroit. I would love to continue my community building around cloud native and open source projects. [Read More]

Totaling almost $40/month to run I was envious of my friends who have virtually unlimited access to cloud compute. [Read More]
