Kubernetes Jobs

Created for work related testing of Kubernetes Jobs

Components

• Kubernetes Deployment and different types of job manifests
• job-logger, small web server written in Golang that basically logs different messages depending on which endpoint/path you access with GET
• job-sender, small Golang program that sends a HTTP requests that are based on environment variables exposed to the Pod (in this case)

How-to

1. docker login to your Docker Hub account
2. make dockerize, this will build and push the two images needed (job-sender and job-logger)
3. Reference your Docker Hub account and image names in all Kubernetes manifests. Or keep the images provided by me.
4. kubectl apply the Deployment, make sure that the job-logger web server starts and works as expected.
5. kubectl apply one job manifest at a time, tail the logs of the job-logger so that you can see the results.

The end result will be a number of log messages logged by job-logger for every Kubernetes Job run and the combination of completions and parallellism settings on the Job.
