I'm trying to mimic volumes_from using Openshift/Kubernetes. I have container A packaging the app and container B server the packaged app.

I cannot use init containers since I'm stuck on kubernetes 1.2.

I've tried the postStart lifecycle hook, detailed here: How to mimic '--volumes-from' in Kubernetes

But, Openshift/Kubernetes is always complaining that container A is contantly crashing because once it's done packaging, it exits.

How do I get Openshift/Kubernetes to stop complaining about container A crashing and just accept that it finished it's job?

Or is there another way of having one container build a package for another container to run?

Thanks in advance for your time.

Update 1: I don't have kubectl, but using oc describe pod myapp-2-prehook:
