Demo repository to create a simple Spring Boot Docker Image and run it as container

Getting started

Dev environment setup

• Use IntelliJ or Eclipse as IDE
• As standalone editor VSCode is recommended (especially for Kubernetes or Docker)
• Ensure Docker is installed
  • If Windows is used, the usage of a Linux VM is highly recommended (OracleVM, Vagrant)
• Ensure Maven is installed and points to the right JRE
  • Otherwise you may use given Maven executable (./mvnw)
• Additional tooling
  • OpenJDK 11+
  • DBeaver for Database access
  • Postman for REST CRUD operations against APIs

Run the application

Manually

1. Start Postgres DB container by executing ./start-postgreSQL.sh
2. Start the application in Spring profile ldev
   • either by IDE
   • with Maven (mvn springboot:run)
   • or by CLI java -jar target/spring-boot-microservices-service-0.0.1-SNAPSHOT.jar

Docker compose

1. Run ./docker-run.sh to create an base image of the application
2. Run docker-compose up

Hint

• Make sure to give your shell scripts execution rights: chmod +x
• In bash you stop a script by pressing CTRL+C
• run ./docker-logs.sh in a new terminal to see server logs
