(LXD) LXC container not starting services automatically

  • 772

Using: Ubuntu Server 14.04 x64 LXD 2.0.0

I have several containers (all of them running "alpine-edge") in which I'm running lighttpd + mysql.

The problem is that each time I restart the containers I have to restart manually those services as they don't start automatically.

What do I need to do to fix that?

UPDATE

The temporally work-around that I'm using is to:

lxc exec alpine-edge service lighttpd start

from the parent OS (inside an init script). But I believe there should be a way to do it automatically inside the container, so if I manually reboot it (the container), I don't have to execute that command each time.

    Alpine Linux uses OpenRC for its init system. The basic commands to interact with it are

    rc-update add <service> [runlevel]

    adds service to the init sequence (similarly to systemd's systemctl enable <service> in Ubuntu 15.04 and forward);

    rc-update del <service> [runlevel]

    stops service from starting during system init (similarly to systemd's systemctl disable <service>);

    rc-service <service> [start stop restart]

    manages currently running services (similarly to systemd's systemctl [start stop restart] <service>, or equivalently /etc/init.d/service [start stop restart] which works in both systemd and OpenRC).

    More information can be found on the Alpine Wiki page I linked to above, and a cheatsheet for OpenRC-systemd translation is available here.
