Is It Possible to Cache Build Layers When Using Buildah Commands in a Shell Script?

[zicklag]

Hey there!

I'm looking into using buildah by using the buildah command line in a shell script to build a container, but I noticed that there's not necessarily a good way to cache the image layers if I'm not using a Containerfile.

I feel like this would be really difficult/impossible to accomplish without some sort of custom cache system, but I wanted to make sure that there wasn't any way that I'm missing to cache build layers when using the buildah CLI in a shell script.

Thanks!

There is no way currently, it has been talked about and some people have attempted but no one has been successful, as far as I know.

@zicklag This is being discussed here : #1292. But afaik there is no plan yet.
