This page is gold. It lays out all of the distrobox assemble api with some good examples of how to get access to things like podman and kind from inside of containers.

Especially this example.

Today I learned that you can use init_hooks to access host machine commands from inside a distrobox container. This is super handy for things that you cannot get to from inside the container and need ran outside (docker, podman, flatpak, xdg-open).

init_hooks=ln -sf /usr/bin/distrobox-host-exec /usr/local/bin/podman;

💭 podman requries qemu-system on ubuntu

podman requires qemu-system on

❯ podman machine init
Looking up Podman Machine image at quay.io/podman/machine-os:5.1 to create VM
Extracting compressed file: podman-machine-default-amd64.qcow2: done
Error: exec: "qemu-img": executable file not found in $PATH

The fix to this for me was to install qemu-system before podman machine init.

sudo apt update

sudo apt install qemu-system

podman comes with a nice command for generating systemd service files (units).

I kept running into limits in the number of subuid and subgid’s I had on my system by default. As always thank the arch wiki guide for having the most comprehensive yet consice guide to setup podman.

What I needed to do to fix the error.

💭 How to pull from images from docker.io with podman

2023-07-28T14:59:37Z

gistfile1.txt text

On void linux.

Under `/etc/containers/` there is a file called `registries.conf`. It is complemented by `man 5 containers-registries.conf`.

Change (for me lines 11-12) which say

[registries.search]
registries = []


to

[registries.search] registries = ['docker.io']

(drawn from https://www.projectatomic.io/blog/2018/05/podman-tls/) Without the above you won’t be able to use basic podman functions. You might get errors like: Error: unable to pull fedora:28: image name provided is a short name and no search registries are defined in the registries config file. Error: unable to pull stripe/stripe-cli: image name provided is a short name and no search registries are defined in the registries config file. Various documentation (redhat blog entries, man podman pages) say that dockerhub is a default, but without this step it’s clearly not.

Good luck. Feel free to use the comment box below if you have a github account.

By default podman will not pull images from docker.io and will need setup. This guide worked for me.
