Spring Cloud Prototype

Prototype codes to build a multi-module spring cloud project.

Preparation

• JDK 8 Installed
• Docker Daemon Running

Build Docker Images

sudo -E ./for_each_app ./docker.modlue.sh build

The build process requires an access to fetch following internet resources:

• Jcenter Repository
• Docker Hub Repository
• Alpine Linux Repository

Run Applications in Docker

sudo -E docker-compose -p focussource-demo -f docker/docker-compose.yml up -d

After all applications started up, visit the Spring Boot Admin Doashboard (http://localhost:8803/) to check registered services states.
