Extended Java Shop

This repo contains code samples for the book "Continuous Delivery in Java". It started as a fork of Daniel Bryant's O'Reilly Docker Java Shopping repository, but it evolved to become a repository on its own right. Problems running the code? Raise a new issue.

This README is intended to provide high-level guidance of the project, and detailed instructions can be found in the accompanying book.

Project Structure

Further instructions may exist within the following sub-folders.

• acceptance-tests
  • Simple examples of functional end-to-end tests that use JUnit, REST-assured, and SerenityBDD to test the entire set of services comprising the Extended Java Shop.
• external-adaptive-pricing
  • Service that represents some adaptive pricing service provided by a supposed third party.
• fake-adaptive-pricing
  • The fake service that a team would use for tests, instead of the real external-adaptive-pricing service.
• featureflags
  • The Feature Flags Service that is used within the Extended Java Shop to decide which features should be enabled and to what degree.
• featureflags-db
  • The DB used by the Feature Flags Service. In this case it will be just a Postgre DB in a Docker container, in a real-life situation it would be a proper database.
• jenkins-aws-ecs
  • A pre-built Jenkins instance that deploys to a known AWS ECS Cluster; this is based on jenkins-base.
• jenkins-base
  • A pre-built Jenkins instance with job definitions for all the services and tests. It includes an empty "deploy" job which doesn't do anything; this job is overridden at jenkins-kubernetes and jenkins-aws-ecs to deploy to the right location.
• jenkins-kubernetes
  • A pre-built Jenkins instance that deploys to a locally running Kubernetes Cluster; this is based on jenkins-base.
• productcatalogue
  • The Product Catalogue Service, which provides product details like name and price.
• shopfront
  • The Shopfront Service that provides the primary entry point for the end-user (both Web UI and API-driven).
• stockmanager
  • The Stock Manager Service, which provides stock information, such as SKU and available quantity.
• test-featureflags-db
  • The DB used by Feature Flags Service in the test environment. In this case, like featureflags-db, it's just a Postgre DB in a Docker container, although in a real-life situation it would probably be a proper database.
