Running Docker inside of a LXD container
Docker can be used inside of LXD containers, allowing for some specific applications and services to be installed through Docker just as one would on a physical server or virtual machine.
This can be useful to have LXD provide full system containers or virtual machines for a variety of users or projects, some using Docker and some not.
COMMANDS:
lxc storage create docker btrfs
lxc storage volume create docker demo
lxc launch images:ubuntu/20.04 demo
lxc config device add demo docker disk pool=docker source=demo path=/var/lib/docker
lxc config set demo security.nesting=true security.syscalls.intercept.setxattr=true security.syscalls.intercept.mknod=true
