How to run the application

To run the application, follow these steps:

1. Build the Project:

   • Ensure you have Java 24, Gradle, and Node.js installed.
   • Run the following command to build the project:

       ./gradlew build
     

   2. Prepare Frontend Resources:
      • Build the Angular frontend by navigating to the jambotron-ui directory and running

      cd jambotron-ui
      

      • next:

      npm install
      

      • next:

      npm run build
      

   • This will generate the frontend files in the jambotron-ui/dist/jambotron-ui/browser directory.

2. Copy Frontend Resources:

   • Use the Gradle task to copy the frontend resources to the jumbotron/src/main/resources/public directory:

     cd ..
     

     • next:

     ./gradlew copyResources
     

   then

3. Create postgres server and database:

   • Create a PostgreSQL database

     • named jambotronDB with the
     • user admin and
     • password postgrespw.

   • You can use a PostgreSQL client or run the following command in your terminal:

     CREATE DATABASE jambotronDB;
     CREATE USER admin WITH PASSWORD 'postgrespw';
     GRANT ALL PRIVILEGES ON DATABASE jambotronDB TO admin;
     

   • If you are using Docker, you can run PostgreSQL using the following command:

     docker run --name postgresDB -p 5432:5432 -e POSTGRES_USER=admin -e POSTGRES_PASSWORD=postgrespw -e POSTGRES_DB=jambotronDB -d postgres
     

   • if you are wont to use pgadmin

        docker run --name pgadmin -e "PGADMIN_DEFAULT_EMAIL=name@example.com" -e "PGADMIN_DEFAULT_PASSWORD=admin" -p 5050:80 -d dpage/pgadmin4
     

     then

   • create a network for the containers to communicate:

     docker network create --driver bridge pgnetwork
     

     • Show list of networks:

     docker network ls
     

     • Connect pgadmin to the network:

     docker network connect pgnetwork pgadmin
     

     • Connect postgresDB to the network (postgresDB must by running):

     docker network connect pgnetwork postgresDB
     

     • Inspect the network to ensure both containers are connected:

     docker network inspect pgnetwork
     

4. Run the Application:

   • Start the Spring Boot application:

     ./gradlew bootRun
     

5. Access the Application:

   • Open your browser and navigate to http://localhost:8080.

Make sure all dependencies and configurations are correctly set up before running these steps.

How to run the application in Docker

To run the application in Docker, follow these steps:

• build jar file

./gradlew bootJar

• Run docker compose to start the application and PostgreSQL:

docker-compose -f src/Docker/docker-compose.yml up -d  

• For connection from pgadmin use hostename: host.docker.internal

How to run the application in Docker with HTTPS support

To run the application in Docker with HTTPS support, follow these steps:

1. Cerbot

   • Run this command below to get certificate and store it to volume certs.

   • Expanded(readable) command example:

   docker run -d
   --name certbot
   -v certs:/etc/letsencrypt
   -v certs-data:/var/lib/letsencrypt
   -p 80:80
   -p 443:443
   certbot/certbot
   certonly --standalone --preferred-challenges http --email youremail@gmail.com -d yourdomain.com --agree-tos

   • Command to run certbot with specific domain and email:

   docker run -d --name certbot -v certs:/etc/letsencrypt -v certs-data:/var/lib/letsencrypt -p 8081:80 -p 8443:443 certbot/certbot certonly --standalone --preferred-challenges http --email liosha84@gmail.com -d jambotron.run.place --agree-tos
   

   • Tip: You can generate certificate to local machine used next command:

   docker run -it --rm -p 8081:80 --name certbot -v "C:\certbot\etc\letsencrypt:/etc/letsencrypt" -v "C:\certbot\var\lib\letsencrypt:/var/lib/letsencrypt" certbot/certbot certonly --standalone -d jambotron.run.place 
   

   certificate files will be stored in C:\certbot\etc\letsencrypt and C:\certbot\var\lib\letsencrypt directories.

   • If you have same trouble before running certbot, run this project Helper_projects/spring-boot-https-main insted of jambotron project.

   • TODO: Add cron job to renew certificate automatically.
