[lxc-users] how to determine if in LXD

[Lago Gonzalez, Diego]

Hello,

There are several ways you can use to know if you are in an LXD container.

First of all, you can check if $container variable is defined inside a shell; and its contents. If so, you are in a container.

Other way is checking if /dev/lxd directory exists. That directory/device is created only if you are inside an LXD container.

Finally, you can use virt-what command (in Ubuntu, you can install it with apt).

Best regards.

Try `systemd-detect-virt` on systemd-based distros, or `running-in-container` on upstart-based distros.
