You can add the required etc configuration files to your environment:

{ config, pkgs, ... }:
{
  environment = {
    etc."containers/registries.conf".text = import ./etc/containers/registries.nix {};
    etc."containers/policy.json".text     = import ./etc/containers/policy.nix {};
  };
}

I use nix for generating my configuration in /etc, e.g.

{}:''
[registries.search]
registries = ['docker.io', 'quay.io', "gcr.io", "eu.gcr.io"]
''

pinage404 · 2019-07-21T11:50:36Z

I added etc."containers/registries.conf" and etc."containers/policy.json"

But i still have the problem

sudo podman info
[sudo] Mot de passe de pinage404 :
could not get runtime: could not find a working binary (configured options: [/usr/bin/runc /usr/sbin/runc /usr/local/bin/runc /usr/local/sbin/runc /sbin/runc /bin/runc /usr/lib/cri-o-runc/sbin/runc]): invalid argument

It seems normal that podman can't find thoses paths under NixOS

But i don't know how you can run it without any other configuration

I found this in man 'libpod.conf'

 runtime_path=""
         Paths to search for a valid OCI runtime binary

But i don't know how to get the nix store path of runc

xaverdh · 2019-07-22T09:57:03Z

runc has its own package. You can get the store path to the binary via "${pkgs.runc.bin}/bin/runc".

periklis · 2019-07-22T10:26:59Z

You can amend your ~/.config/containers/libpod.conf:

conmon_path = ["/run/current-system/sw/bin/conmon", "/usr/libexec/podman/conmon", "/usr/libexec/crio/conmon", "/usr/local/lib/podman/conmon", "/usr/local/libexec/crio/conmon", "/usr/bin/conmon", "/usr/sbin/conmon", "/usr/lib/crio/bin/conmon"]
conmon_env_vars = ["PATH=/run/current-system/sw/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin"]

[runtimes]
  runc = ["/run/current-system/sw/bin/runc", "/usr/bin/runc", "/usr/sbin/runc", "/usr/local/bin/runc", "/usr/local/sbin/runc", "/sbin/runc", "/bin/runc", "/usr/lib/cri-o-runc/sbin/runc"]

In addition, you will probably need to install: runc, conmon and slirp4netns.

I'm having the same problems with podman. Why doesn't this work out of the box?

saschagrunert · 2019-08-18T20:37:05Z

We would need a configuration wrapper for podman, which is currently under development in #54925

VanCoding · 2019-09-11T15:17:25Z

Is it possible to use podman inside a nix-shell, without requiring it to be installed globally?
Together with podman-compose, that would be a awesome and make docker & docker-compose obsolete.

x80486 · 2019-09-22T00:55:04Z

I know most of you (if not all) are referring to NixOS here, but since the package is also available for Linux, I'm wondering if this should also cover running podman correctly as well under that operating system.

I just installed it and I'm getting something similar:

@VanCoding

Is it possible to use podman inside a nix-shell, without requiring it to be installed globally?

Yes it is, nix-shell -p podman conmon runc slirp4netns. The only global configuration I had to do was set up subuids and subgids for my account.

adisbladis · 2019-11-26T19:10:31Z

I made a shell.nix that's completely self-contained for running podman: https://gist.github.com/adisbladis/187204cb772800489ee3dac4acdd9947.
It also maps the docker command to podman within the shell.

The only thing you have to setup globally is the subuid/subgid ranges for your user.

danieldk · 2020-03-01T14:34:50Z

For some reason configuration files in ~/.config often break and podman expects them in /etc/containers. So, I have started running podman in an FHS:

https://github.com/danieldk/nix-home/blob/master/overlays/20-podman.nix

So far, so good...
