Autostarting LXC containers

By default, LXC containers do not start after a server reboot. To change that, we can use the lxc-autostart tool and the containers configuration file:

1. To demonstrate this, let's create a new container first:

         root@ubuntu:~# lxc-create --name autostart_container --template 
         ubuntu
   
         root@ubuntu:~# lxc-ls -f
   
         NAME STATE AUTOSTART GROUPS IPV4 IPV6
   
         autostart_container STOPPED 0 - - -
   
         root@ubuntu:~#
   

2. Next, add the lxc.start.auto stanza to its config file:

         root@ubuntu:~# echo "lxc.start.auto = 1" >> 
         /var/lib/lxc/autostart_container/config
   
         root@ubuntu:~#
   

3. List all containers that are configured to start automatically:

         root@ubuntu:~# lxc-autostart --list
   
         autostart_container
   
         root@ubuntu:~#
   

4. Now we can use the lxc-autostart command again to start all containers configured to autostart, in this case just one:

         root@ubuntu:~# lxc-autostart --all
        ...
