It uses Consul as a DNS server for service discovery. 13 | Service names are postfixed with `.service.consul` on registration with Consul 14 | through [Registrator](https://github.com/gliderlabs/registrator) 15 | which monitors the Unix Socket `docker.sock` and automatically registers and deregisteres 16 | all Docker Containers running on a host. Services resolve their 17 | communication partner's current IP addresses over ordinary DNS resolution, 18 | thereby making service implementations independent 19 | of any Consul-specific APIs. 20 | 21 | This project creates a complete microservice demo system in Docker 22 | containers. The services are implemented in Java using Spring and 23 | Spring Cloud. 24 | 25 | It uses three microservices: 26 | - `Order` to process orders. (http://localhost:8080 when started locally) 27 | - `Customer` to handle customer data. (http://localhost:8080) 28 | - `Catalog` to handle the items in the catalog. (http://localhost:8080) 29 | 30 | Consul 31 | ------ 32 | 33 | Consul has a Web UI. You can access it at port 8500 of your Docker 34 | host. Also the homepage at port 8080 contains a link to the Consul UI 35 | 36 | Also you can use Consul's DNS interface with e.g. dig: 37 | 38 | ``` 39 | dig @localhost msconsuldns_order.service.consul. 40 | dig @localhost msconsuldns_order.service.consul. ANY 41 | dig @localhost msconsuldns_order.service.consul. SRV 42 | ``` 43 | 44 | Note that the demo uses the original 45 | [Consul Docker image](https://hub.docker.com/_/consul/) provided by 46 | Hashicorp. However, the demo does not use a Consul cluster and only 47 | stores the data in memory i.e. it is certainly not fit for production. 48 | 49 | The Consul DNS interface is mapped to port 53 on the Docker Host. The 50 | Docker containers are configured with to use the IP adress of the 51 | Docker Host as the DNS server. 52 | 53 | [Registrator](https://github.com/gliderlabs/registrator) registers all 54 | Docker containers including the Spring Cloud microservices (customer, 55 | catalog and order) 56 | 57 | Apache HTTP Load Balancer 58 | ------------------------ 59 | 60 | Apache HTTP is used to provide the web page of the demo at 61 | port 8080. It also forwards HTTP requests to the microservices whose ports 62 | are not exposed! Apache HTTP is configured as a reverse proxy for this - and 63 | as a load balancer i.e. if you start multiple instances of a microservices 64 | e.g. via `docker-compose scale catalog=2`, Apache will recognize the new instance. 65 | 66 | To configure this Apache HTTP needs to get all registered services from 67 | Consul. [Consul Template](https://github.com/hashicorp/consul-template) 68 | is used for this. It uses a template for the Apache HTTP 69 | configuration and fills in the IP addresses of the registered services. 70 | 71 | The Docker container therefore runs two processes: Apache HTTP and 72 | Consul Template. Consul Template starts Apache httpd and also restarts 73 | Apache httpd when new services are registered in the Consul server. 74 | 75 | Please refer to the subdirectory `apache` to see how this works. 76 | 77 | 78 | Technologies 79 | ------------ 80 | 81 | - Consul for Lookup/ Discovery 82 | - Apache as a reverse proxy to route calls to the appropriate SCS. 83 | 84 | How To Run 85 | ---------- 86 | 87 | The demo can be run with [Docker Machine and Docker 88 | Compose](docker/README.md) via `docker-compose up` 89 | 90 | See [How to run](HOW-TO-RUN.md) for details. 91 | 92 | Remarks on the Code 93 | ------------------- 94 | 95 | The servers for the infrastructure components are pretty simple thanks to Spring Cloud: 96 | 97 | The microservices are: 98 | 99 | - [microservice-consuldns-demo-catalog](microservice-consuldns-demo/microservice-consuldns-demo-catalog) is the application to take care of items. 100 | - [microservice-consuldns-demo-customer](microservice-consuldns-demo/microservice-consuldns-demo-customer) is responsible for customers. 101 | - [microservice-consuldns-demo-order](microservice-consuldns-demo/microservice-consuldns-demo-order) does order processing. It uses microservice-demo-catalog and microservice-demo-customer. 102 | 103 | 104 | The microservices have a Java main application in `src/test/java` to run them stand alone. `microservice-demo-order` uses a stub for the other services then. Also there are tests that use _consumer-driven contracts_. That is why it is ensured that the services provide the correct interface. These CDC tests are used in microservice-demo-order to verify the stubs. In `microservice-demo-customer` and `microserivce-demo-catalog` they are used to verify the implemented REST services. 105 | -------------------------------------------------------------------------------- /microservice-consuldns-demo/mvnw.cmd: -------------------------------------------------------------------------------- 1 | @REM ---------------------------------------------------------------------------- 2 | @REM Licensed to the Apache Software Foundation (ASF) under one 3 | @REM or more contributor license agreements.

See 8 | https://www.java.com/en/download/help/download_options.xml . The 9 | examples need to be compiled so you need to install a JDK (Java 10 | Development Kit). A JRE (Java Runtime Environment) is not 11 | sufficient. After the installation you should be able to execute 12 | `java` and `javac` on the command line. 13 | 14 | * The example run in Docker Containers. You need to install Docker 15 | Community Edition, see https://www.docker.com/community-edition/ 16 | . You should be able to run `docker` after the installation. 17 | 18 | * The example need a lot of RAM. You should configure Docker to use 4 19 | GB of RAM. Otherwise Docker containers might be killed due to lack 20 | of RAM. On Windows and macOS you can find the RAM setting in the 21 | Docker application under Preferences/ Advanced. 22 | 23 | * After installing Docker you should also be able to run 24 | `docker-compose`. If this is not possible, you might need to install 25 | it separately. See https://docs.docker.com/compose/install/ . 26 | 27 | ## Build 28 | 29 | Change to the directory `microservice-consul-demo` and run `./mvnw clean 30 | package` or `mvnw.cmd clean package` (Windows). This will take a while: 31 | 32 | ``` 33 | [~/microservice-consuldns/microservice-consuldns-demo]./mvnw clean package 34 | .... 35 | [INFO] 36 | [INFO] --- maven-jar-plugin:2.6:jar (default-jar) @ microservice-consuldns-demo-order --- 37 | [INFO] Building jar: /Users/wolff/microservice-consuldns/microservice-consuldns-demo/microservice-consuldns-demo-order/target/microservice-consuldns-demo-order-0.0.1-SNAPSHOT.jar 38 | [INFO] 39 | [INFO] --- spring-boot-maven-plugin:1.4.5.RELEASE:repackage (default) @ microservice-consuldns-demo-order --- 40 | [INFO] ------------------------------------------------------------------------ 41 | [INFO] Reactor Summary: 42 | [INFO] 43 | [INFO] microservice-consuldns-demo ...........................

If in 60 | doubt: delete the file. 61 | 62 | * The tests use some ports on the local machine. Make sure that no 63 | server runs in the background. 64 | 65 | * Skip the tests: `./mvnw clean package 66 | -Dmaven.test.skip=true` or `mvnw.cmd clean package 67 | -Dmaven.test.skip=true` (Windows). 68 | 69 | * In rare cases dependencies might not be downloaded correctly. In 70 | that case: Remove the directory `repository` in the directory `.m2` 71 | in your home directory. Note that this means all dependencies will 72 | be downloaded again. 73 | 74 | ## Run the containers 75 | 76 | First you need to build the Docker images. Change to the directory 77 | `docker` and run `docker-compose build`. This will download some base 78 | images, install software into Docker images and will therefore take 79 | its time: 80 | 81 | ``` 82 | [~/microservice-consuldns/docker]docker-compose build 83 | .... 84 | Removing intermediate container 1d59f8227b12 85 | Step 4/4 : EXPOSE 8989 86 | ---> Running in 11e7fbacfa01 87 | ---> 9cfa7772986f 88 | Removing intermediate container 11e7fbacfa01 89 | Successfully built 9cfa7772986f 90 | ``` 91 | 92 | Afterwards the Docker images should have been created. They have the prefix 93 | `msconsuldns`: 94 | 95 | ``` 96 | [~/microservice-consuldns/docker]docker images 97 | REPOSITORY TAG IMAGE ID CREATED SIZE 98 | msconsuldns_order latest 12b279e78975 52 seconds ago 225MB 99 | msconsuldns_apache latest 22fac099ba93 55 seconds ago 255MB 100 | msconsuldns_catalog latest c23c535ecaf6 2 minutes ago 225MB 101 | msconsuldns_customer latest a780e4f49bac 2 minutes ago 225MB 102 | ``` 103 | 104 | Figure out the IP adress of your system and set it to the environment 105 | variable CONSUL_HOST. This is needed to ensure that the containers are 106 | able to use Consul as a DNS server. 107 | 108 | ``` 109 | [~/microservice-consuldns/docker]ifconfig 110 | .... 111 | en5: flags=8863 mtu 1500 112 | .... 113 | inet 192.168.1.152 netmask 0xffffff00 broadcast 192.168.1.255 114 | .... 115 | [~/microservice-consuldns/docker]export CONSUL_HOST=192.168.1.152 116 | ``` 117 | 118 | 119 | Now you can start the containers using `docker-compose up -d`. The 120 | `-d` option means that the containers will be started in the 121 | background and won't output their stdout to the command line: 122 | 123 | ``` 124 | [~/microservice-consuldns/docker]docker-compose up -d 125 | Creating network "msconsuldns_default" with the default driver 126 | Pulling consul (consul:0.7.2)... 127 | 0.7.2: Pulling from library/consul 128 | b7f33cc0b48e: Already exists 129 | a4ca795d20eb: Pull complete 130 | 76bc5ef06918: Pull complete 131 | 965e633cb8c2: Pull complete 132 | 64e424fcbe65: Pull complete 133 | Digest: sha256:ce15f85417a0cf121d943563dedb873c7d6c26e9b1e8b47bc2f1b5a3e27498e1 134 | Status: Downloaded newer image for consul:0.7.2 135 | Creating msconsuldns_consul_1 ... 136 | Creating msconsuldns_consul_1 ... done 137 | Creating msconsuldns_order_1 ... 138 | Creating msconsuldns_catalog_1 ... 139 | Creating msconsuldns_customer_1 ... 140 | Creating msconsuldns_apache_1 ... 141 | Creating msconsuldns_order_1 142 | Creating msconsuldns_catalog_1 143 | Creating msconsuldns_apache_1 144 | Creating msconsuldns_apache_1 ... done 145 | ``` 146 | 147 | As you can see the Consul Docker image is downloaded now. 148 | 149 | Check wether all containers are running: 150 | 151 | ``` 152 | [~/microservice-consuldns/docker]docker ps 153 | CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 154 | 2697aa91700b msconsuldns_apache "/bin/sh -c '/usr/..." 4 minutes ago Up 4 minutes 0.0.0.0:8080->80/tcp msconsuldns_apache_1 155 | 948f2576b0b0 msconsuldns_customer "/bin/sh -c '/usr/..." 4 minutes ago Up 4 minutes 8080/tcp msconsuldns_customer_1 156 | 0574e8dc5b11 msconsuldns_order "/bin/sh -c '/usr/..." 4 minutes ago Up 4 minutes 8080/tcp msconsuldns_order_1 157 | 144542583a05 msconsuldns_catalog "/bin/sh -c '/usr/..." 4 minutes ago Up 4 minutes 8080/tcp msconsuldns_catalog_1 158 | c28d2a38f657 consul:0.7.2 "docker-entrypoint..." 4 minutes ago Up 4 minutes 8300-8302/tcp, 8400/tcp, 8600/tcp, 8301-8302/udp, 0.0.0.0:8500->8500/tcp, 0.0.0.0:8600->8600/udp msconsuldns_consul_1 159 | ``` 160 | `docker ps -a` also shows the terminated Docker containers. That is 161 | useful to see Docker containers that crashed rigth after they started. 162 | 163 | If one of the containers is not running, you can look at its logs using 164 | e.g. `docker logs msconsuldns_apache_1`. The name of the container is 165 | given in the last column of the output of `docker ps`. Looking at the 166 | logs even works after the container has been 167 | terminated. If the log says that the container has been `killed`, you 168 | need to increase the RAM assigned to Docker to e.g. 4GB. On Windows 169 | and macOS you can find the RAM setting in the Docker application under 170 | Preferences/ Advanced. 171 | 172 | If you need to do more trouble shooting open a shell in the container 173 | using e.g. `docker exec -it msconsuldns_catalog_1 /bin/sh` or execute 174 | command using `docker exec msconsuldns_catalog_1 /bin/ls`. 175 | 176 | You can access the microservices at http://localhost:8080/ 177 | and the Consul dashboard 178 | at http://localhost:8500 . 179 | 180 | You can terminate all containers using `docker-compose down`. 181 | 182 | If the order container cannot find the other containers, make sure 183 | that no firewall is running on the Docker host. At least on Mac OS X 184 | the firewall blocks the DNS requests. 185 | -------------------------------------------------------------------------------- /WIE-LAUFEN.md: -------------------------------------------------------------------------------- 1 | # Beispiel starten 2 | 3 | Die ist eine Schritt-für-Schritt-Anleitung zum Starten der Beispiele. 4 | Informationen zu Maven und Docker finden sich im 5 | [Cheatsheet-Projekt](https://github.com/ewolff/cheatsheets-DE). 6 | 7 | ## Installation 8 | 9 | * Die Beispiele sind in Java implementiert. Daher muss Java 10 | installiert werden. Die Anleitung findet sich unter 11 | https://www.java.com/en/download/help/download_options.xml . Da die 12 | Beispiele kompiliert werden müssen, muss ein JDK (Java Development 13 | Kit) installiert werden. Das JRE (Java Runtime Environment) reicht 14 | nicht aus. Nach der Installation sollte sowohl `java` und `javac` in 15 | der Eingabeaufforderung möglich sein. 16 | 17 | * Die Beispiele laufen in Docker Containern. Dazu ist eine 18 | Installation von Docker Community Edition notwendig, siehe 19 | https://www.docker.com/community-edition/ . Docker kann mit 20 | `docker` aufgerufen werden. Das sollte nach der Installation ohne 21 | Fehler möglich sein. 22 | 23 | * Die Beispiele benötigen zum Teil sehr viel Speicher. Daher sollte 24 | Docker ca. 4 GB zur Verfügung haben. Sonst kann es vorkommen, dass 25 | Docker Container aus Speichermangel beendet werden. Unter Windows 26 | und macOS findet sich die Einstellung dafür in der Docker-Anwendung 27 | unter Preferences/ Advanced. 28 | 29 | * Nach der Installation von Docker sollte `docker-compose` aufrufbar 30 | sein. Wenn Docker Compose nicht aufgerufen werden kann, ist es nicht 31 | als Teil der Docker Community Edition installiert worden. Dann ist 32 | eine separate Installation notwendig, siehe 33 | https://docs.docker.com/compose/install/ . 34 | 35 | ## Build 36 | 37 | Wechsel in das Verzeichnis `microservice-consuldns-demo` und starte `./mvnw clean 38 | package` bzw. `mvnw.cmd clean package` (Windows).

Die 134 | Option `-d` bedeutet, dass die Container im Hintergrund gestartet 135 | werden und keine Ausgabe auf der Kommandozeile erzeugen. 136 | 137 | ``` 138 | [~/microservice-consuldns/docker]docker-compose up -d 139 | Creating network "msconsuldns_default" with the default driver 140 | Pulling consul (consul:0.7.2)... 141 | 0.7.2: Pulling from library/consul 142 | b7f33cc0b48e: Already exists 143 | a4ca795d20eb: Pull complete 144 | 76bc5ef06918: Pull complete 145 | 965e633cb8c2: Pull complete 146 | 64e424fcbe65: Pull complete 147 | Digest: sha256:ce15f85417a0cf121d943563dedb873c7d6c26e9b1e8b47bc2f1b5a3e27498e1 148 | Status: Downloaded newer image for consul:0.7.2 149 | Creating msconsuldns_consul_1 ... 150 | Creating msconsuldns_consul_1 ... done 151 | Creating msconsuldns_order_1 ... 152 | Creating msconsuldns_catalog_1 ... 153 | Creating msconsuldns_customer_1 ... 154 | Creating msconsuldns_apache_1 ... 155 | Creating msconsuldns_order_1 156 | Creating msconsuldns_catalog_1 157 | Creating msconsuldns_apache_1 158 | Creating msconsuldns_apache_1 ... done 159 | ``` 160 | 161 | Wie man sieht, werden nun auch noch Docker Images heruntergeladen. 162 | 163 | Du kannst nun überprüfen, ob alle Docker Container laufen: 164 | 165 | ``` 166 | [~/microservice-consuldns/docker]docker ps 167 | CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 168 | 2697aa91700b msconsuldns_apache "/bin/sh -c '/usr/..." 4 minutes ago Up 4 minutes 0.0.0.0:8080->80/tcp msconsuldns_apache_1 169 | 948f2576b0b0 msconsuldns_customer "/bin/sh -c '/usr/..." 4 minutes ago Up 4 minutes 8080/tcp msconsuldns_customer_1 170 | 0574e8dc5b11 msconsuldns_order "/bin/sh -c '/usr/..." 4 minutes ago Up 4 minutes 8080/tcp msconsuldns_order_1 171 | 144542583a05 msconsuldns_catalog "/bin/sh -c '/usr/..." 4 minutes ago Up 4 minutes 8080/tcp msconsuldns_catalog_1 172 | c28d2a38f657 consul:0.7.2 "docker-entrypoint..." 4 minutes ago Up 4 minutes 8300-8302/tcp, 8400/tcp, 8600/tcp, 8301-8302/udp, 0.0.0.0:8500->8500/tcp, 0.0.0.0:8600->8600/udp msconsuldns_consul_1 173 | ``` 174 | `docker ps -a` zeigt auch die terminierten Docker Container an. Das 175 | ist nützlich, wenn ein Docker Container sich sofort nach dem Start 176 | wieder beendet.. 177 | 178 | Wenn einer der Docker Container nicht läuft, kannst du dir die Logs 179 | beispielsweise mit `docker logs msconsuldns_apache_1` anschauen. Der Name 180 | der Container steht in der letzten Spalte der Ausgabe von `docker 181 | ps`. Das Anzeigen der Logs funktioniert auch dann, wenn der Container 182 | bereits beendet worden ist. Falls im Log steht, dass der Container 183 | `killed` ist, dann hat Docker den Container wegen Speichermangel 184 | beendet. Du solltest Docker mehr RAM zuweisen z.B. 4GB. Unter Windows 185 | und macOS findet sich die RAM-Einstellung in der Docker application 186 | unter Preferences/ Advanced. 187 | 188 | Um einen Container genauer zu untersuchen, kannst du eine Shell in dem 189 | Container starten. Beispielsweise mit `docker exec -it 190 | msconsuldns_catalog_1 /bin/sh` oder du kannst in dem Container ein 191 | Kommando mit `docker exec msconsuldns_catalog_1 /bin/ls` ausführen. 192 | 193 | Du kannst auf die Microservices unter http://localhost:8080/ 194 | zugreifen und 195 | auf das Consul Dashboard unter http://localhost:8500 . 196 | 197 | Mit `docker-compose down` kannst Du alle Container beenden. 198 | 199 | Wenn der Order-Container die anderen Container nicht finden kann, 200 | schalte die Firewall auf dem Docker Host aus. Zumindest unter Mac OS X 201 | unterbindet die Firewall die DNS-Zugriffe. 202 | -------------------------------------------------------------------------------- /LICENSE: -------------------------------------------------------------------------------- 1 | Apache License 2 | Version 2.0, January 2004 3 | http://www.apache.org/licenses/ 4 | 5 | TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION 6 | 7 | 1.
