rce-images

Important

Prebuilt images can be found on Docker Hub.

Overview

This are runtime docker images used for running user code. The images are built using nix which are pinned to a specific nixpkgs commit to create reproducible images.

rce-runner

The rce-runner is installed in each image which writes the files inside the container, compiles and runs the code and returns the result as a json payload.

Usage

Input:

echo '{
  "language": "javascript",
  "files": [{
