podman: ssh-agent mount failure on macOS 12.3

**OS: ** macOS 12.3 “Monterey”

Description I can’t pull from internal GitHub repos on macOS. Other coworkers using Fedora have indicated they don’t have any issues. Basically, I have this person on stack overflow’s exact problem

Create a dockerfile

FROM registry.access.redhat.com/ubi8/s2i-core:latest
RUN --mount=type=ssh yum install -y openssh-clients && ssh-add -l

Run podman build . --ssh default Result:

Could not open a connection to your authentication agent.
Error: error building at STEP "RUN --mount=type=ssh yum install -y openssh-clients && ssh-add -l": error while running runtime: exit status 2

Docker for Mac has an ssh-auth.sock that is located at /run/host-services/ssh-auth.sock that forwards the requests to the users ssh-agent running on the macOS host.

See https://docs.docker.com/desktop/networking/#ssh-agent-forwarding

I think problem is that SSH_AUTH_SOCK which ssh-agent uses to communicate exists on host and not on machine. I’m just curious if this ever worked on podman machine before.

I think we would need to mount SSH_AUTH_SOCK from host->machine

Maybe this issue can be moved to podman, since this has to implemented on podman side. This might need mount to work between host and machine on macOS.
