LXD is a next generation system container manager. It offers a user experience similar to virtual machines but using Linux containers instead. It allows an easier management and deployment of LXC containers.
For now, Alpine Linux has a LXD package only for Edge so, first of all, you have to upgrade to Edge.
Then, let's start installing lxd and dbus packages (dbus is needed for some containers as they refuse to start if unavailable)
apk add lxd dbus
Then, let's set some options to be able to run the containers as unprivileged:
echo "session optional pam_cgfs.so -c freezer,memory,name=systemd,unified" >> /etc/pam.d/system-login echo "lxc.idmap = u 0 100000 65536" >> /etc/lxc/default.conf echo "lxc.idmap = g 0 100000 65536" >> /etc/lxc/default.conf echo "root:100000:65536" >> /etc/subuid echo "root:100000:65536" >> /etc/subgid
If you plan to run systemd based Linux distributions (Debian, Ubuntu, etc.), add this to /etc/conf.d/lxc:
and enable both lxc and lxd at boot:
rc-update add lxc rc-update add lxd
If you have problems, try to enable dbus:
rc-update add dbus
Reboot and lxd should be working.
