UQ Cloud Computing Course Final Project: A web application that allows users to find projects to collaborate on and also sell their artifacts

HobbyMate

HobbyMate is a web application that lets you find projects to work on and also lets you advertise your projects to others. Once you complete your project you can list your artefact in the shop. The audience are hobbyist and anyone interested in collaborating with others on projects.

Technologies

• Spring Boot
• Angular
• Netflix Eureka (Service Discovery)
• Netflix Ribbon (Clientside LoadBalancing) - Eureka runs at http://localhost:8761/

Firewall

• Port 9797 (Web Application)
• Port 8095 (API Server - Gateway)

Make sure you allow these ports through your GCP firewall settings.

Load Balancing

When deployed to docker swarm project-service is run as two replicas. The instances will register with discovery-service (Eureka). The microservices can easilly scale.

Important NOTE

Please allow time for all the microservices to start as they may fail due to databases not being ready. They'll reconnect on reboot.

Database Issues!

cleans all the volumes for mysql

docker-compose rm -v -f
docker volume prune -f

Where is the app?

After running with docker compose or deploying to swarm the app will be available at http://localhost:9797 or http://<your gcp external ip>:9797/

Building & Running

The jar files have been included so that they can be put into docker images.

1. Easy option

This option will use the jarfiles in the project to build the images.

Run with compose

docker-compose up --build --force-recreate

When fully ready go to: http://<your gcp external ip>:9797/

Deploy to swarm

docker-compose build  --force-rm
docker swarm init
docker stack deploy --compose-file=docker-compose.yml hobbymate

When fully ready go to: http://<your gcp external ip>:9797/

2. Recompiling Java and building images

This option requires that you have Java 17.0.4 installed to build the project. This is in case there's an issue running the jars I've provided.

Build

./mvnw clean package -DskipTests=true

Then deploy to swarm or;

Give the services sometime to start they will take a while as some will be attempting to connect to the DB while it's still being launched.

docker-compose build  --force-rm
docker swarm init
docker stack deploy --compose-file=docker-compose.yml hobbymate

Run with docker-compose

Give the services sometime to start they will take a while as some will be attempting to connect to the DB while it's still being launched.

docker-compose up --build --force-recreate
