[Podman] Re: Build image from Pod Yaml like in docker-compose

Bobes, This is an extremely interesting use case, and not one I was familiar with. Could you share an example docker-compose file that you would like to convert to Kube YAML? I know you've made a recommendation on the Kube YAML you'd like to see, but that feels like specifying an interface without completely verifying the use case. If we could see the source/origin docker-compose YAML, that would really help the engineering team validate the design of the interface in the Kube YAML. AFAIK, there is not native Build directive in Kube, so we would need something like BuildConfig in OpenShift. There's also a new upstream project that Red Hat is sponsoring which be Kubernetes neutral (aka not OpenShift only). That might be something we could target as well, but I'll need to go chase down the project upstream. A quick google search did not turn anything up.
