In the backend directory :

# Warning, the admin password appears at the first start of the backend
npm start

In the frontend directory :

npm run start-react

In the dockerAPI directory :

npm start

Config of docker chall

Create new chall in ADMIN_MODE. In "Docker", put the github link to the file where you put your docker-compose. /!\ Warning, put the tree link /!\ Example : https://github.com/Gomez0015/CTFCafe_Docker_Chall_Test/tree/main/challTest

Useful commands

If you had a problem creating your docker instance, enter this command in the mongo database:

db.docker.drop();

It will allow you to delete the docker instances created

To know

You would not be able to access the platform on your local network, you will have to replace "localhost" with "your IP" in the ".env" of /frontEnd, /backEnd and /dockerAPI.
