Sample 2 | =========================== 3 | 4 | [Deutsche Anleitung zum Starten des Beispiels](WIE-LAUFEN.md) 5 | 6 | This demo uses [Kubernetes](https://kubernetes.io/) as Docker 7 | environment. Kubernetes also support service discovery and load 8 | balancing. An Apache httpd as a reverse proxy routes the calls to the 9 | services. 10 | 11 | Also the demo uses [linkerd](https://linkerd.io/) for features like 12 | monitoring, fault injection, and circuit breaking. 13 | 14 | This project creates a complete micro service demo system in Docker 15 | containers. The services are implemented in Java using Spring Boot and 16 | Spring Cloud. 17 | 18 | 19 | It uses three microservices: 20 | - `Order` to accept orders. 21 | - `Shipping` to ship the orders. 22 | - `Invoicing` to ship invoices. 23 | 24 | How to run 25 | --------- 26 | 27 | See [How to run](HOW-TO-RUN.md). 28 | 29 | 30 | Remarks on the Code 31 | ------------------- 32 | 33 | The microservices are: 34 | - [microservice-linkerd-order](microservice-linkerd-demo/microservice-linkerd-order) to create the orders 35 | - [microserivce-linkerd-shipping](microservice-linkerd-demo/microservice-linkerd-shipping) for the shipping 36 | - [microservice-linkerd-invoicing](microservice-linkerd-demo/microservice-linkerd-invoicing) for the invoices 37 | 38 | The microservices have an Java main application in `src/test/java` to 39 | run them stand alone. microservice-demo-shipping and 40 | microservice-demo-invoicing both use a stub for the 41 | other order service for the tests. 42 | 43 | The data of an order is copied - including the data of the customer 44 | and the items. So if a customer or item changes in the order system 45 | this does not influence existing shipments and invoices. It would be 46 | odd if a change to a price would also change existing invoices. Also 47 | only the information needed for the shipment and the invoice are 48 | copied over to the other systems. 49 | 50 | The job to poll the order feed is run every 30 seconds. 51 | 52 | -------------------------------------------------------------------------------- /microservice-linkerd-bonus/.mvn/wrapper/MavenWrapperDownloader.java: -------------------------------------------------------------------------------- 1 | /* 2 | Licensed to the Apache Software Foundation (ASF) under one 3 | or more contributor license agreements.
