Ok, I really want to use podman, but the last time I built an image and tried to run it, I ran into a brick wall. I think I used something called buildah to package something, and it had some parameter for a name, but then trying to run it using podman, podman didn't seem to have any way to reference the container image that I THINK buildah created. I think there was also something called spokeo but I don't recall what it did, or it did not help this workflow. The tutorials all seemed to assume pulling images from the internet. Anyone have a good podman tutorial that really goes from install podman -> make container -> run container on a Linux box?

This works for me on Ubuntu 22.10: $ sudo apt install podman buildah $ mkdir empty && cd empty $ cat > Containerfile <<EOF FROM alpine:3.14 RUN echo 'echo hello podman!' > /root/hello.sh ENTRYPOINT ["/bin/sh", "/root/hello.sh"] EOF $ buildah build -f Containerfile -t hello-podman . $ podman run -it --rm localhost/hello-podman:latest hello podman! edit: stryan has more minimalist instructions above.

  AH, so it must be the localhost/hello-podman:latest was the axle-wrap. I will now bitch about how everything needs to be converted to some obscure url or pseudo-url when a file path would do. This has bitten me on: - JSP tag libraries - XML xsd references (which back in the Spring XML namespace-go-nuts era was really annoying) - file:///fully/qualified/path There, I have bitched.

Were you building from a Dockerfile or Containerfile? If so, you don't need to use buildah you can just use podman build, same as you would docker. So to build an image from a Dockerfile/Containerfile in the current directory just run podman build -t what_the_image_to_be_tagged . Then to reference the container by name when you run it, you gotta specify that at runtime: podman run --name foo the_image_you_just_tagged
