How to Install LXC on OpenBSD

LXC (Linux Containers) is a Linux-based container technology that allows you to run multiple isolated Linux systems (containers) on a single host. In this tutorial, we'll go over how to install LXC on OpenBSD.

Step 1: Installing Dependencies

Before installing LXC on OpenBSD, we need to install some dependencies. OpenBSD's package manager, pkg_add, can be used to install the necessary packages.

$doas pkg_add libxml2 libxslt libffi

Step 2: Installing LXC

Next, we need to download and install LXC. We will be downloading the source code from the official LXC website.

$doas pkg_add curl

$ curl -L -O https://linuxcontainers.org/downloads/lxc/lxc-4.0.12.tar.gz

$ tar xvzf lxc-4.0.12.tar.gz

$cd lxc-4.0.12

$ ./configure

$ make

$doas make install

Step 3: Configuring LXC

After installing LXC, we need to make some configuration adjustments. We'll start by creating a configuration file for LXC.

$doas vi /etc/lxc/lxc.conf

Add the following lines to the file:

lxc.apparmor.profile = generated
lxc.apparmor.allow_nesting = 1
lxc.cap.drop = sys_module mac_admin mac_override

Step 4: Running LXC

Now that LXC is installed and configured, we can start using it. The lxcd service that comes with OpenBSD is used to manage LXC containers.

The following command will start the lxcd service:

$doas rcctl enable lxcd
$doas rcctl start lxcd

Conclusion

In this tutorial, we've gone over how to install LXC on OpenBSD. By following these steps, you should now have LXC up and running on your OpenBSD system.

If you want to self-host in an easy, hands free way, need an external IP address, or simply want your data in your own hands, give IPv6.rs a try!

Alternatively, for the best virtual desktop, try Shells!
