Podman secret mount error in Windows

Issue Description

I think my issue is related to this closed issue. I'm on windows and trying to mount a secret into an image I'm building but it doesn't work. I tried building the secret in a compose file and using podman compose with the 1.2.0 version but it doesn't work either. I think the problem comes from how secrets are mounted in podman.

Steps to reproduce the issue

I first created a secret named rsa_private_key using podman secret create rsa_private_key ./rsa_private_key.txt which gave me the following output: 4bf444f9a65ec70ce89c41fd9.

Running podman secret ls shows the secret does exist:

ID                         NAME             DRIVER      CREATED         UPDATED
4bf444f9a65ec70ce89c41fd9  rsa_private_key  file        16 minutes ago  16 minutes ago

I tried running this simple Containerfile:

FROM ubuntu:23.04
RUN --mount=type=secret,id=rsa_private_key cat /run/secrets/rsa_private_key

Then I simply run podman build -t testimage ..

Describe the results you received

And I keep getting this output when running podman build -t testimage .:

STEP 1/2: FROM ubuntu:23.04
STEP 2/2: RUN --mount=type=secret,id=rsa_private_key cat /run/secrets/rsa_private_key
cat: /run/secrets/rsa_private_key: No such file or directory
Error: building at STEP "RUN --mount=type=secret,id=rsa_private_key cat /run/secrets/rsa_private_key": while running runtime: exit status 1

Describe the results you expected

I expected the image to be created with no issue but it seems like mounting secrets on windows does not work.
