How to intentionally fail a job in kubernetes?

I have an image of java code that does database validation and the job uses that image. I want the job to intentionally fail when the database validation fails. Is there any way to do the same?

Solution

  • A Kubernetes job is just a contrainer running. As with any container, the final exit code determines if the run was successful or not. So, to make your job fail you need to exit with a code other than 0.
