ArchLinux NerdCTL

Arch is a lot like Slackware and Gentoo, whilst it does have a package manager, you have to know what you want before things work

so NerdCTL has the ability to use buildkit to install stuff on multi-arch but that isn’t as easy as you would like and as such there are a few things that need installing to make it work

Steps

This will need YAY (well there are others but if you copy paste then its yay)

Install

yay -S nerdctl kubectl qemu-user-static rootlesskit slirp4netns buildkit

Setup

sudo loginctl enable-linger $(whoami) sudo vi /etc/sysctl.d/99-rootless.conf

kernel.unprivileged_userns_clone=1
net.ipv4.ping_group_range = 0 2147483647
net.ipv4.ip_unprivileged_port_start=0

sudo touch /etc/subuid /etc/subgid sudo sudo usermod --add-subuids 100000-165535 --add-subgids 100000-165535 $(whoami)

Rootless

containerd-rootless-setuptool.sh install && containerd-rootless-setuptool.sh install-buildkit
systemctl enable --user --now containerd && systemctl enable --user --now buildkit

Containerd needs to also be run as root in order to do multi-arch

sudo systemctl enable --now containerd sudo nerdctl run --privileged --rm tonistiigi/binfmt --install all

[Unit]
Description=MultiArch
After=containerd.service

[Service]
Type=simple
ExecStart=nerdctl run --privileged --rm tonistiigi/binfmt --install all > /dev/null

[Install]
WantedBy=multi-user.target

sudo systemctl enable --now multi-arch

Reason

This is mainly for me so I have a backup of the requirements for next time I need to install it
