I also have the same issue, what I did is create a symbolic link

doas ln -s $(which podman) /opt/homebrew/bin/docker

swap /opt/homebrew/bin to /usr/local/bin if you're on x86

Hi!

Indeed, it uses the docker library to inspect the images.
I will take a look how to improve this part.

I'm also on padman nowadays.
@timescam's hack works for me. But it would be nice to be able to just set an env var or smth that whalebrew would respect.

This build contains the dev version of podman support.
It would be great to have your feedback about it.
What works and what not.

On MacOS, you will need to run xattr -d com.apple.quarantine whalebrew-Darwin-$(uname -m) to be able to remove the macOS download warnings and use it.

For me this is not working:

  • create a temp dir
  • download the arm64 build to there
  • removing quarantine and set +x
  • add current dir to PATH
  • rename downloaded file to whalebrew

Do note that running the container directly with podman works:

Thanks for your input @memark
I think the problem you are facing is that whalebrew mounts the working directory to the container, as described in "How it works"

Because of the way podman and docker works on mac (i.e running in a vm) they don't have access to all folders on the machine.

I think, using the same script and replacing whalesay running with podman! by podman run --rm -v $PWD:/workdir whalebrew/whalesay running with podman! you will have the same problem.
Would it be worth trying?

Here is the result on my machine (x86):

❯ mktemp -d
/var/folders/0d/rvmll2615l19k0sy4g734kcm0000gn/T/tmp.r0XgqFvd

❯ podman run --rm -v /var/folders/0d/rvmll2615l19k0sy4g734kcm0000gn/T/tmp.r0XgqFvd:/workdir --rm whalebrew/whalesay running with podman!
Error: statfs /var/folders/0d/rvmll2615l19k0sy4g734kcm0000gn/T/tmp.r0XgqFvd: no such file or directory

In case you would try the same thing with whalebrew 4.1.0, not having this support, you would get:

❯ whalebrew version
Whalebrew 0.4.1

❯ whalebrew install whalebrew/whalesay
failed to inspect docker image: Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?

❯ whalesay
exec: "docker": executable file not found in $PATH

I don't have enough knowledge on podman to tell you whether it is achievable with podman or not. With a super quick search I find this issue talking about $HOME but not sure it talks about other volumes

@tjamet Actually your first podman example works fine on my machine:

❯ mktemp -d
/var/folders/pz/cl5g3tqx5yd20d7ylmx629x00000gn/T/tmp.zHTSCXYx8p

❯ podman run --rm -v /var/folders/pz/cl5g3tqx5yd20d7ylmx629x00000gn/T/tmp.zHTSCXYx8p:/workdir whalebrew/whalesay running with podman!

(TBH I don't know much about podman inner workings. I just switched to it due to the changed made to the Docker Desktop licensing model.)

This is interesting.

Whalebrew runs this exact command (assuming podman is in /usr/local/bin/podman, the whalesay file was not changed from the standard installation, the current directory on the host OS is /var/folders/0d/rvmll2615l19k0sy4g734kcm0000gn/T/tmp.2w5oppGh and the current user ID on the local machine is 501.):

❯ /usr/local/bin/podman "run" "--interactive" "--rm" "--workdir" "/workdir" "--init" "--tty" "-v" "/var/folders/0d/rvmll2615l19k0sy4g734kcm0000gn/T/tmp.2w5oppGh:/workdir" "-u" "501:20" "whalebrew/whalesay" "running" "with" "podman"

Would this command work for you?

I have just tried again with the command from this build, on a mac with m2, the commands above, those worked for me, even running in a temporary directory.

podman client: 4.7.0
podman server: 4.6.2

Do you still observe the behaviour with whalebrew?

memark avatar memark commented on May 25, 2024

With that build it works for me to (install and) run whalesay in the normal way. Good work!
