I've typically used Ubuntu containers in Proxmox, but have recently started spinning up Arch Linux containers due to the low resource requirements. This is more internal documentation on building them so I don't need to reference it later. There seems to be a nuance with Proxmox and Arch Linux where it needs to be an unprivileged container for networking to "just work" at boot.
Please note this is for an internal lab and isn't designed to be Internet-facing.
Uncomment the mirrors for your region, initialize and populate the keyring, and update everything to the latest:
vi /etc/pacman.d/mirrorlist pacman-key --init pacman-key --populate archlinux pacman -Sy gnupg archlinux-keyring pacman-key --refresh-keys pacman -Syu
Configure the timezone:
ln -sf /usr/share/zoneinfo/Region/City /etc/localtime # For example: # ln -fs /usr/share/zoneinfo/America/Detroit /etc/localtime
Set the language:
echo "LC_ALL=en_US.UTF-8" >> /etc/environment echo "en_US.UTF-8 UTF-8" >> /etc/locale.gen echo "LANG=en_US.UTF-8" >> /etc/locale.conf locale-gen en_US.UTF-8
systemctl enable sshd systemctl start sshd
Create a user:
useradd -m -G wheel -s /bin/bash username passwd username # For example: # useradd -m -G wheel -s /bin/bash nlabadie # passwd nlabadie
Install a bunch of packages. YMMV depending on your requirements:
pacman -S pacman-contrib base-devel sudo neovim bash-completion git nmap tcpdump mlocate bind-tools tmux zsh
Add the user you'd created above to the sudoers file:
visudo # I typically uncomment this line. %wheel ALL=(ALL) NOPASSWD: ALL
Install yay for the AUR packages:
# Switch to the user you'd created above. # e.g. su - nlabadie su - username git clone https://aur.archlinux.org/yay-git.git cd yay-git makepkg -si
Install the symlinks for neovim:
yay -S neovim-symlinks
Fix a few items with the Arch template:
# If it's an unprivileged container. setcap cap_net_raw+p /bin/ping
Install zsh and a bunch of plugins. Full instructions are available here:
You should have a light-weight Arch Linux LXC at this point. Hope this helps!
