RCE

A Code engine built to simplify remote code execution.

Credits • Features • Download • Setup • Support

Credits

The software has been developed using the following packages:

• NodeJs
• Express
• Docker
• Amazon-S3

Features

The general architecture of the engine

Download

To download the project use the following command

#clone the project
$ git clone https://github.com/ryuusama09/Remote-Code-Execution-Engine.git

Setup

once the project is cloned on your local system , you need to install the dependencies. make sure you have Docker-Desktop

#installs dependencies
$ npm install 

once all the dependencies , make sure you have you set the file script.sh in worker/images as LF type in the text-editor of your choice. also make sure you have no docker-container running on port 7000
now we will setup the docker shared volume and build the rest of the application

# creates docker volume "shared"
$ docker volume create shared

# build images 
$ docker build --no-cache -t rce/spawner worker/images/cpp

# the above commands need to be executed only once while initially setting up the project
# engine trigger command
$ docker-compose up --build

After running all the commands step-wise , you should be able to see that servers for server, worker and rabbitmq should be running

Testing

for this you are required to have amazon-S3 subscription , where the input file and source code file are uploaded. the post requests need to be sent to http://localhost:7000/api/submit. the body contains :

• "src" : amazon-s3-source-code-link
• "stdin" : amazon-s3-input-file-link
• "lang" : language of the source code

Example

Using postman , i will demonstrate the process

upon a valid submission , you would be able to see that the code has been successfully executed.
In the terminal , you should be able to see the output.
In future we plan to directly upolad the output file back to s3.
