podman-remote build, with '*' in .dockerignore: overzealously ignores Dockerfile

[edsantiago]

Setup:

$ mkdir aaa
$ echo "FROM scratch" >aaa/Dockerfile
$ echo '*' >aaa/.dockerignore
$ ./bin/podman system service --timeout=0

In window 2:

$ ./bin/podman-remote build aaa
Error: stat /dev/shm/libpod_builder306103659/build/Dockerfile: no such file or directory

Regular (non-remote) podman works fine, presumably because it doesn't do the interim copy of the context dir to $TMPDIR:

$ ./bin/podman build aaa
STEP 1: FROM scratch
STEP 2: COMMIT
--> 7c21f8178f5

@vrothberg @nalind This I guess is an issue with the copier, where we should special case Containerfile and Dockerfile to not be ignored when * is specified.

@edsantiago did you try this out on Docker?

[edsantiago]

I didn't. I'm delighted I mean heartbroken to say I no longer have access to any hosts or VMs with docker.

[rhatdan]

Sadly I still have it installed, for just this type of occurrance, and yes it works on Docker.

I don't see the copier package being used in the build bindings: https://github.com/containers/podman/blob/master/pkg/bindings/images/build.go#L333. As mentioned in the other issue, I think the build bindings should use the copier package.

I am usually volunteered :^) Pipeline is long but we crossed the 200 issues threshold :)

This works for me with the latest in the main branch.

It actually doesn't work. I suspect you shortcutted my reproducer above, running podman system service in the same directory as the Dockerfile and .dockerignore. Can you try my exact reproducer, no shortcuts? Reopening while we sort this out.
