code-execution-engine

An API which executes codes in a sandbox environment 🙀🤯.

Leave a star if U like it 😀

Architecture

Running the API

Prerequisites

Docker and docker compose should be installed in the system

Step 1 :

Clone the repo

Step 2 : building the images

sudo docker-compose build

Step 3 : running the images

sudo docker-compose up

Step 4 : Testing if its working

If its running on localhost then ping the server using

• On terminal:

    curl http://localhost:9090/
  

  We will get a response saying Hello from Titan-Engine with status code 200.

• On browser :

  paste the url http://localhost:9090/ and see the response.

• On Postman : (recommended)

  Sending a json post request to http://localhost:9090/submit

  It is a c++ script which takes 2 input and print's it.

  {
  "src": "\n\n#include<bits/stdc++.h>\n\nusing namespace std ;\n\nint main()\n{\n    int a ;\n    cin >> a ;\n\n    cout << \"The first number is \" << a << endl ;\n    \n    int b ;\n    cin >> b ;\n    \n    cout << \"The second number is \" << b << endl ;\n\n    cout << \"Hello from cpp\" <<endl ;\n\n    // while(1)\n    // {\n    //     cout << 1 << endl ;\n    // }\n    return 0;\n}\n\n",
  "stdin": "48\n95",
  "lang": "cpp",
  "timeout": "5"
  }

  
  

  

  we will get a response like

    http://localhost:9090/results/Test646d62525e1b09171058
  

  Run this response in postman or browser

  

Yay Its working 😎😎👌👏

Understanding post request and responses

Post

src contains the scripts in raw formate.

stdin contains the inputs in raw formate.

lang the programming language.

timeout number of seconds the program will run.(Max 5 sec)

Response

we will get a response like

http://localhost:9090/results/Test646d62525e1b09171058

Run this response in postman or browser

output The output of the script

status status of the output

stderr error in code

submission_id the unique submission id

error_message the error message time time taken to run the script

Different types of status:

"status": "Invalid Request"

If the field in post request is empty then it will show invalid request

"status":"Queued"

If the request is in waiting stage i.e. in queue.

"status":"Processing"

If the script is running

"status":"Runtime Error"

If the exec command fails for some reason in worker nodes

"status":"Failed"

Causes due to compilation error or runtime error.

"status":"Successful"

Everything is OK

PORT 8080 and PORT 9090

The docker-compose exposes 2 ports

https The port 8080 uses self signed ssl certificate.

http The port 9090 can be used for debugging.
