Bookstore Application

This application is inspired by istios bookinfo example app. It is intended to demonstrate modern development practices such as microservices and containerization. The code accompanies a lecture held at TUM Heilbronn.

The main purpose of the application is to expose static information about books via a restful API.

Every component is a separate Spring Boot application, which you can find in its dedicated folder.

Getting Started

GitHub Actions

The repository comes with a ready to use GitHub workflow, which takes care of the continuous integration part for you. To use it, make sure to set it up correctly:

1. Create repository secrets for your DOCKER_USERNAME and your DOCKER_PASSWORD. Do not store sensitive information such as your username or password in the repository. Always use an encrypted storage for that.
2. Select the bookstore component that you want to build. This can be done via the COMPONENT environment variable in the workflow file

The workflow will be triggered for every change that you do on the main branch. As a result of a successful workflow run you will see a new Docker image in your personal DockerHub repository. The naming schema is as follows:

${{secrets.DOCKER_USERNAME}}/bookstore-${{ env.COMPONENT }}:${{github.run_number}}

Every run creates a new tag to prevent cache issues while fetching the image.
