ENOENT when running via podman

[asymmetric]

What's the problem you want solved?

I followed the Docker instructions, while under the hood using podman.

After bulding the image with docker build --tag oasis --file contrib/Dockerfile ., I tried running it with:

docker run --mount type=volume,src=ssb,target=/home/node/.ssb --publish 127.0.0.0:3000:3000 --rm oasis

(note: I had to specify type=volume above)

This failed with

Worth pointing out that I'm running NixOS, and that xdg-open is at /nix/store/41iyp469y2c9bpkg8rggyk2hr6w5m73z-xdg-utils-1.1.3/bin/xdg-open.

Thanks for reporting this problem. Could you try adding the --no-open flag?

That did get me further:

(Note that I had to re-specify the contents of CMD, because it gets overwritten by any args one passes to run - ENTRYPOINT would be a better choice, AFAIK)

Turns out that the instructions in docs/with-docker.md have an error: --publish 127.0.0.0:3000:3000 should be --publish 127.0.0.1:3000:3000.

After changing that, I can access oasis at 0.0.0.0:3000!
