LXD demo server

This repository contains the backend code of the LXD online demo service.

https://linuxcontainers.org/lxd/try-it

What is it

Simply put, it's a small Go daemon exposing a REST API that users (mostly our javascript client) can interact with to create temporary test containers and attach to that container's console.

Those containers come with a bunch of resource limitations and an expiry, when the container expires, it's automatically deleted.

The main client can be found at the URL above, with its source available here:
https://github.com/lxc/linuxcontainers.org

Installing on Ubuntu

The easiest way to get the demo server running on Ubuntu is by using the snap package.

First install and configure LXD itself:

sudo snap install lxd
sudo lxd init

Then install and configure the LXD demo server:

sudo snap install lxd-demo-server
sudo snap connect lxd-demo-server:lxd lxd:lxd
sudo lxd-demo-server.configure

You can then access the server at: http://IP-ADDRESS:8080/

Dependencies

The server needs to be able to talk to a LXD daemon over the local unix socket, so you need to have a LXD daemon installed and functional before using this server.

Other than that, you can pull all the other necessary dependencies with:

go get github.com/lxc/lxd-demo-server

Building it

A very simple:

go build

Should do the trick.

Running it

To run your own, you should start by copying the example configuration file "lxd-demo.yaml.example" to "lxd-demo.yaml", then update its content according to your environment.

You will either need a container to copy for every request or a container image to use, set that up and set the appropriate configuration key.

Once done, simply run the daemon with:

./lxd-demo-server

The daemon isn't verbose at all, in fact it will only log critical LXD errors.

You can test things with:

curl http://localhost:8080/1.0
curl http://localhost:8080/1.0/terms

The server monitors the current directory for changes to its configuration file. It will automatically reload the configuration after it's changed.
