LetsCode

LetsCode is a web-based application designed to assist in learning basic programming. In LetsCode, basic programming learning material is presented in the form of problems that must be solved together by the learning pair (implementation of distributed pair programming). The application allows users to learn the basics of programming in an interactive and enjoyable way.

To install LetsCode, make sure you have installed Docker on system. Docker is a platform for running and managing containers, which are lightweight and portable units that encapsulate an application and its dependencies.

Once Docker is installed, follow these steps to install LetsCode:

1. Create an .env file:

   • Create a new file named .env in the same directory as your .env.sample file.
   • Copy the contents of the .env.sample file (or you can copy .env.sample to .env)
   • Replace the placeholders with the actual values that you want to use.
   • Save the .env file.

2. Go to fe directory and create an .env file:

   • Create a new file named .env in the same directory as your .env.sample file. (make sure you are in fe directory)
   • Copy the contents of the .env.sample file (or you can copy .env.sample to .env)
   • Replace the placeholders with the actual values that you want to use.
   • Save the .env file.

3. Build the application with Docker Compose:

   • Open a terminal or command prompt in the same directory as your docker-compose.yml file.
   • Run the command docker-compose build. This will build all the Docker images defined in the docker-compose.yml file.

4. Run the application with Docker Compose:

   • In the terminal or command prompt, run this command

   docker-compose up -d db redis rabbitmq
   sleep 10
   docker-compose up -d
   

   • You can see the log of containers by executing the command docker logs letscode-nameofimage
