If not you can find details how to [get started](http://fabric8.io/guide/getStarted/index.html). 14 | 15 | Assuming your current shell is connected to Kubernetes or OpenShift so that you can type a command like 16 | 17 | ``` 18 | kubectl get pods 19 | ``` 20 | 21 | or for OpenShift 22 | 23 | ``` 24 | oc get pods 25 | ``` 26 | 27 | Then the following command will package your app and run it on Kubernetes: 28 | 29 | ``` 30 | mvn fabric8:run 31 | ``` 32 | 33 | To list all the running pods: 34 | 35 | oc get pods 36 | 37 | Then find the name of the pod that runs this quickstart, and output the logs from the running pods with: 38 | 39 | oc logs 40 | 41 | You can also use the [fabric8 developer console](http://fabric8.io/guide/console.html) to manage the running pods, and view logs and much more. 42 | 43 | 44 | #### Integration Testing 45 | 46 | The example includes a [fabric8 arquillian](https://github.com/fabric8io/fabric8/tree/master/components/fabric8-arquillian) Kubernetes Integration Test. 47 | Once the container image has been built and deployed in Kubernetes, the integration test can be run with: 48 | 49 | mvn test -Dtest=*KT 50 | 51 | The test is disabled by default and has to be enabled using `-Dtest`. [Integration Testing](https://fabric8.io/guide/testing.html) and [Fabric8 Arquillian Extension](https://fabric8.io/guide/arquillian.html) provide more information on writing full fledged black box integration tests for Kubernetes. 52 | 53 | ### More details 54 | 55 | You can find more details about running this [quickstart](http://fabric8.io/guide/quickstarts/running.html) on the website. This also includes instructions how to change the Docker image user and registry. 56 | 57 | 58 | ### Access services using a web browser 59 | 60 | When the application is running, you can use a web browser to access the REST service. Assuming that you 61 | have a [Vagrant setup](http://fabric8.io/guide/getStarted/vagrant.html) you can access the REST service with 62 | `http://spring-boot-webmvc-default.vagrant.f8`. 63 | 64 | Notice: As it depends on your OpenShift setup, the hostname (route) might vary. Verify with `oc get routes` which 65 | hostname is valid for you. Add the '-Dfabric8.deploy.createExternalUrls=true' option to your maven commands if you want it to deploy a Route configuration for the service. 66 | 67 | The URL `http://spring-boot-webmvc-default.vagrant.f8/ip` can be used to obtain the IP address to show service load-balancing 68 | when running with multiple pods. 69 | 70 | 71 | #### Integration Testing 72 | 73 | The example includes a [fabric8 arquillian](https://github.com/fabric8io/fabric8/tree/master/components/fabric8-arquillian) Kubernetes Integration Test. 74 | Once the container image has been built and deployed in Kubernetes, the integration test can be run with: 75 | 76 | mvn test -Dtest=*KT 77 | 78 | The test is disabled by default and has to be enabled using `-Dtest`. [Integration Testing](https://fabric8.io/guide/testing.html) and [Fabric8 Arquillian Extension](https://fabric8.io/guide/arquillian.html) provide more information on writing full fledged black box integration tests for Kubernetes. 79 | 80 | ### More details 81 | 82 | You can find more details about running this [quickstart](http://fabric8.io/guide/quickstarts/running.html) on the website. This also includes instructions how to change the Docker image user and registry. 83 | 84 | -------------------------------------------------------------------------------- /pom.xml: -------------------------------------------------------------------------------- 1 | 2 | 19 | 20 | 21 | 4.0.0 22 | 23 | io.fabric8.quickstarts 24 | spring-boot-webmvc 25 | 1.0-SNAPSHOT 26 | 27 | Fabric8 :: Quickstarts :: Spring-Boot :: WebMVC 28 | Shows how to use Spring Boot with WebMVC in the Java Container 29 | 30 | 31 | UTF-8 32 | 33 | 34 | 2.3.2 35 | 1.5.4.RELEASE 36 | 37 | 38 | 3.5.28 39 | 1.5.0 40 | 3.6.0 41 | 2.3 42 | 2.19.1 43 | 44 | 45 | 46 | 47 | 48 | 49 | io.fabric8 50 | fabric8-project-bom-with-platform-deps 51 | ${fabric8.version} 52 | pom 53 | import 54 | 55 | 56 | org.springframework.boot 57 | spring-boot-dependencies 58 | ${spring-boot.version} 59 | pom 60 | import 61 | 62 | 63 | 64 | 65 | 66 | 67 | 68 | 69 | org.springframework.boot 70 | spring-boot-starter-web 71 | 72 | 73 | org.springframework.boot 74 | spring-boot-starter-actuator 75 | 76 | 77 | 78 | 79 | org.springframework.boot 80 | spring-boot-starter-test 81 | test 82 | 83 | 84 | org.jboss.arquillian.junit 85 | arquillian-junit-container 86 | test 87 | 88 | 89 | io.fabric8 90 | fabric8-arquillian 91 | test 92 | 93 | 94 | 95 | 96 | 97 | 98 | 99 | maven-compiler-plugin 100 | ${maven-compiler-plugin.version} 101 | 102 | 1.8 103 | 1.8 104 | 105 | 106 | 107 | 108 | org.apache.maven.plugins 109 | maven-surefire-plugin 110 | ${maven-surefire-plugin.version} 111 | true 112 | 113 | -Djava.security.egd=file:/dev/./urandom 114 | 115 | **/*KT.java 116 | 117 | 118 | 119 | 120 | 121 | org.springframework.boot 122 | spring-boot-maven-plugin 123 | ${spring-boot.version} 124 | 125 | io.fabric8.quickstarts.springbootmvc.App 126 | 127 | 128 | 129 | 130 | repackage 131 | 132 | 133 | 134 | 135 | 136 | 137 | io.fabric8 138 | fabric8-maven-plugin 139 | ${fabric8.maven.plugin.version} 140 | 141 | 142 | 143 | resource 144 | build 145 | 146 | 147 | 148 | 149 | 150 | 151 | 152 | 153 | -------------------------------------------------------------------------------- /src/main/fabric8/configmap.yml: -------------------------------------------------------------------------------- 1 | metadata: 2 | name: ${project.artifactId} 3 | data: 4 | application.properties: | 5 | # spring application properties file 6 | welcome = Hello from Kubernetes ConfigMap!!! 7 | dummy = some value 8 | -------------------------------------------------------------------------------- /src/main/fabric8/deployment.yml: -------------------------------------------------------------------------------- 1 | metadata: 2 | annotations: 3 | configmap.fabric8.io/update-on-change: ${project.artifactId} 4 | spec: 5 | replicas: 1 6 | template: 7 | spec: 8 | volumes: 9 | - name: config 10 | configMap: 11 | name: ${project.artifactId} 12 | items: 13 | - key: application.properties 14 | path: application.properties 15 | containers: 16 | - volumeMounts: 17 | - name: config 18 | mountPath: /deployments/config 19 | -------------------------------------------------------------------------------- /src/main/java/io/fabric8/quickstarts/springbootmvc/App.java: -------------------------------------------------------------------------------- 1 | /** 2 | * Copyright 2005-2016 Red Hat, Inc. 3 | * 4 | * Red Hat licenses this file to you under the Apache License, version 5 | * 2.0 (the "License"); you may not use this file except in compliance 6 | * with the License.
