Prerequisites

For using Github Codespaces, no prerequisites are mandatory. Follow the ./PREREQUISITES.md instructions to configure a local virtual machine with Ubuntu, Docker, IntelliJ.

Access the code

• Fork the code GitHub repository under your Organization
  • https://github.com/UNIBUC-PROD-ENGINEERING/service
• Clone the code repository:
  • [email protected]:YOUR_ORG_NAME/service.git

Run code in Github Codespaces

• Make sure that the Github repository is forked under your account / Organization
• Create a new Codespace from your forked repository
• Wait for the Codespace to be up and running
• Make sure that Docker service has been started
  • docker ps should return no error
• For running all services in docker:
  • Build the docker image of the hello world service
    • make build
  • Start all the service containers
    • ./start.sh
• For running / debugging directly in Visual Studio Code
  • Start the MongoDB related services
    • ./start_mongo_only.sh
  • Start the Spring Boot service by clicking Run button inside Visual Studio Code

NOTE: for a live demo, please check out this youtube video

Run/debug code in IntelliJ

• Build the code
  • IntelliJ will build it automatically
  • If you want to build it from command line and also run unit tests, run: ./gradlew build
• Create an IntelliJ run configuration for a Jar application
  • Add in the configuration the JAR path to the build folder ./build/libs/hello-0.0.1-SNAPSHOT.jar
• Start the MongoDB container using docker compose
  • docker-compose up -d mongo
• Run/debug your IntelliJ run configuration
• Open in your browser:
  • http://localhost:8080/hello-world
  • http://localhost:8080/info

Deploy and run the code locally as docker instance

• Build the docker image of the hello world service

  • make build

• Start all the containers

  • ./start.sh

• Verify that all containers started, by running

  service git:(master) ✗  $ docker ps
  CONTAINER ID   IMAGE           COMMAND                  CREATED         STATUS         PORTS                      NAMES

• Open in your browser:

  • http://localhost:8080/hello-world
  • http://localhost:8080/info

• You can access the MongoDB Admin UI at:

  • http://localhost:8090
