Installing intracom-be-06-2024

Objective: This SOP outlines the steps to install and set up the intracom-be-06-2024 application.

---

Prerequisites:

• SSH access
• Git installed
• Node.js and npm installed
• Docker Desktop installed
• MongoDB community server image available on Docker Hub

---

Steps:

1. Setup SSH Key:

   • Generate an SSH key if you don't have one: ssh-keygen -t rsa -b 4096 -C "your_email@example.com"
   • Add the SSH key to your SSH agent: eval "$(ssh-agent -s)" and ssh-add ~/.ssh/id_rsa
   • Add the SSH key to your GitHub account.

2. Clone the Repository:

   • Clone the intracom-be-06-2024 repository:

     git clone https://github.com/project-ascend-io/intracom-be-06-2024
     cd intracom-be-06-2024

3. Install Dependencies:

   • Navigate to the project directory and run:

     npm install

4. Setup Environment Variables:

   • Create a .env file in the root directory of your project with the following content that matches the .env.template:

     NODE_ENV=development
     PORT=8080
     HOST=localhost
     
     # CORS Settings
     CORS_ORIGIN=http://localhost:*
     
     # Rate Limiting
     COMMON_RATE_LIMIT_WINDOW_MS=1000
     COMMON_RATE_LIMIT_MAX_REQUESTS=20
     
     # MongoDB Settings
     MONGO_INITDB_DATABASE=intracom_database
     MONGO_INITDB_ROOT_USERNAME=root
     MONGO_INITDB_ROOT_PASSWORD=root
     MONGODB_USER=<username>
     MONGODB_PASSWORD=<password>
     MONGODB_CONNECTION_STRING=mongodb://root:root@localhost:27017/
     

5. Install and Run Docker Desktop:

   • Download and install Docker Desktop from Docker's official website.
   • Make sure your Docker Desktop is running.

6. Run Docker Compose:

   • Change directories to the database directory:

     cd database

   • Run the docker-compose command:

      docker-compose up -d --build

7. Setup MongoDB Replica Set:

   • Check to make sure your Docker containers are running:

      docker ps

   • Connect to mongo1 container:

     docker exec -it mongo1 mongosh -u root -p root

   • Run replica set initiation command:

     rs.initiate({_id:'rs0',members:[{_id:0,host:'host.docker.internal:27017',priority:1},{_id:1,host:'host.docker.internal:27018',priority:0.5},{_id:2,host:'host.docker.internal:27019',priority:0.5}]})

   • Verify Replica Set Configuration:

     rs.status()

   • You should see an output with information from the initiate command you used to set up the replica set.

8. Run the Application:

   • Start the application with:

     npm run dev

9. Access the Application:

   • Open your browser and navigate to http://localhost:8080 to see the running application.
