How to: LXC

LXC

Reboot the container

The syntax is:

lxc-stop -n containerNameHere -r

To reboot the container called myhttpd, enter:

lxc-stop -n myhttpd -r

Shut down and kill the container (hard kill)

The syntax is:

lxc-stop -n containerNameHere -k

OR

lxc-stop -n containerNameHere --kill

To forcefully kill and shut down the container called myhttpd, enter:

lxc-stop -n myhttpd -k

To wait TIMEOUT (say 180) seconds before hard-stopping the container, enter:

lxc-stop -n myhttpd -k -t 180

OR

lxc-stop -n myhttpd -k --timeout 180

Clean shutdown (recommended)

The following syntax only request a clean shutdown, do not kill the container tasks if the clean shutdown fail:

lxc-stop -n containerNameHere --nokill

lxc-stop -n myhttpd --nokill

A note about timeouts

To avoid waiting up to 60 seconds and simply perform the requestion action (reboot, shutdown, or hard kill) and exit, pass the -W option:

## hard kill ##

lxc-stop -W -n containerNameHere -k

## reboot ##

lxc-stop -W -n containerNameHere -r

How do I view the container state?

To list only running containers, enter:

lxc-ls --fancy --running

Sample outputs:

To list only stopped containers, enter:

lxc-ls --fancy --stopped

To list both stopped and running containers on the system, enter:

lxc-ls --fancy
