Install Debian containers on Archlinux using LXC

Install the lxc and the debootstrap packages:

# pacman -Sy lxc debootstrap 

Install an Debian container

I will install Debian Buster.

ceremcem

1. Create a new LXC container:

    sudo lxc-create -n mycouch -t debian -B btrfs -- -r buster --packages nano sudo
   

2. Setup CouchDB: https://docs.couchdb.org/en/stable/install/unix.html

3. Set chattr +C for /var/lib/couchdb.

4. Limit the LXC cpu usage. In mycouch/config:

   limits.cpu.allowance 20%
