TIL: if you do ADD --chown in a Dockerfile to add a tarball as a layer, the --chown does not apply to the tarball's content, which makes it pretty useless.

@aoristdual isn't that how it also works normally chown'ing a tarball. It only does the tar file itself, not what is actually coming out of the extraction (those are preserved within the tarball).

I generally chown a directory after extracting it just for this reason (like when I'm doing it in Puppet).

@Kancept Oh, for sure - I was just expecting different behavior when I was adding the tarball content as an image layer. 🤷 Wrong intuition.
