Create a code sandbox with docker-run

How to create a simple web page that let's you run python code (or any other language) from the browser:

These instructions are for ubuntu 20.10, but should be similar for other linux distros.

Install docker-run

Docker-run will be used to run the code. Follow the instructions to install docker-run. Make sure you pull the python image:

docker pull glot/python:latest

Install nginx

Nginx will be used to host the web page

apt install nginx

Add a new site to nginx

curl https://gist.githubusercontent.com/prasmussen/5b1e2a42b295316dd8b1f665fa8589a7/raw/23811a690a7ce446e43c55f37d331403ec91994a/code-sandbox.conf > /etc/nginx/sites-enabled/code-sandbox

Restart nginx to enable the new site

systemctl restart nginx.service

Add the web page

mkdir /home/glot/www
curl https://gist.githubusercontent.com/prasmussen/5b1e2a42b295316dd8b1f665fa8589a7/raw/23811a690a7ce446e43c55f37d331403ec91994a/index.html > /home/glot/www/index.html

Edit /home/glot/www/index.html and change token in the X-Access-Token header to the token you configured when installing docker-run.

Your code sandbox should now be available at http://:8000.

Please read the security section before making your web page available on the internet. Good luck!

A new code runner api: docker-run

Docker-run provides a http api for running code inside transient docker containers. The communication with the docker daemon happens via it's api over a unix socket and is meant to run on the same machine as the docker daemon.

This could be used as a drop-in replacement for the old glot-run if used together with the new glot-run 2.

It is written in Rust and should be a lot easier to set up and configure than glot-run. It also has a lot better error handling and reporting.

Docker-run has been used in production on glot.io since November.
