Question

  1. Build the image devmaq:3.0 from the Dockerfile at ~/home/Dockerfile, and
  2. Export it in OCI format to ~/human-stork/devmac-3.0.tar.
# 1) Build using podman (same Dockerfile)
podman build -t devmaq:3.0 -f ~/home/Dockerfile ~/home

# 2) Make output dir
mkdir -p ~/human-stork

# 3) Save as OCI archive (podman supports oci-archive)
podman save --format oci-archive -o ~/human-stork/devmac-3.0.tar devmaq:3.0

# 4) (Optional verification)
skopeo inspect oci-archive:~/human-stork/devmac-3.0.tar
# or using podman:
podman image inspect devmaq:3.0

Quick checklist / warnings

  • Do not push the image to any registry (you said don’t push). The commands above only touch local storage.
  • Don’t run the image (no docker run / podman run).
  • Ensure podman is installed if you need OCI output; plain docker save produces Docker-archive format, not OCI.
  • If paths differ, replace ~/home/Dockerfile and ~/human-stork/devmac-3.0.tar with your actual locations.
  • If you get permission errors with docker/podman, you may need sudo or to run as a user in the docker group (depending on your system).
