Arch Linux

Arch is not on the k0s officially tested list, but it works. The kernel has everything k0s needs, and systemd is the default init system.

Install the binary

From the AUR:

yay -S k0s-bin

Or manually:

git clone https://aur.archlinux.org/k0s-bin.git
cd k0s-bin
makepkg -si

Via the install script:

curl --proto '=https' --tlsv1.2 -sSf https://get.k0s.sh | sudo sh

Firewall

Arch does not enable a firewall by default. If you use firewalld, open the same ports as Fedora. If you use nftables or iptables directly, open these TCP ports: 6443, 2380, 9443, 8132, 10250, 179.

If you run no firewall, skip this step. K0s will bind to the required ports without restriction.

SELinux

Arch does not ship SELinux. Skip the SELinux configuration unless you have manually installed and enabled it.

Install and start

The commands are identical to standard Fedora:

# Single node
sudo k0s install controller --enable-worker --no-taints
sudo k0s start

# Verify
sudo k0s status
sudo k0s kubectl get nodes

For multi-node setups, follow the same controller/worker split described in the Fedora section.
