5 years ago, the LXD project decided to provide an online demo of its software.
All that users need is a web browser and heading to https://linuxcontainers.org/lxd/try-it

Through that URL, they get root access inside a LXD container running on a shared server. They can then either follow a step by step guide or just do whatever they want until the session expires 30 minutes later.

Since this page went live, over 400000 sessions were created, meaning over 200 strangers got root access inside a LXD container every single day.

Most users follow our terms of service and just want to discover LXD.
Most, but not all...

This talk will go through how the service is run and configured to avoid most common concerns and attacks while still offering something of value to users.

We'll also cover some other places where properly configured unprivileged LXD containers are similarly used to run untrusted code by random strangers.
