环境：OCP 3.4
1. 下载 Jenkins 镜像 （在 MAC 机器上操作）
参考《离线安装 OCP 3.4 之 下载安装介质》 。
docker save -o jenkins-slave.tar.gz registry.access.redhat.com/openshift3/jenkins-slave-base-rhel7 registry.access.redhat.com/openshift3/jenkins-slave-maven-rhel7 registry.access.redhat.com/openshift3/jenkins-slave-nodejs-rhel7
2. 加载 Jenkins 镜像 （在 Registry 机器上操作）
docker load -i jenkins-slave.tar.gz
docker tag registry.access.redhat.com/openshift3/jenkins-slave-base-rhel7 registry.example.com:5000/openshift3/jenkins-slave-base-rhel7
docker push registry.example.com:5000/openshift3/jenkins-slave-base-rhel7
docker tag registry.access.redhat.com/openshift3/jenkins-slave-maven-rhel7 registry.example.com:5000/openshift3/jenkins-slave-maven-rhel7
docker push registry.example.com:5000/openshift3/jenkins-slave-maven-rhel7
docker tag registry.access.redhat.com/openshift3/jenkins-slave-nodejs-rhel7 registry.example.com:5000/openshift3/jenkins-slave-nodejs-rhel7
docker push registry.example.com:5000/openshift3/jenkins-slave-nodejs-rhel7
3. 创建 myphp 应用，但是去掉自动 build 和 自动 deploy （在 Console 上操作）
参考《离线安装 OCP 3.4 之测试 PHP 应用》
点击展开 Show advanced routing, build, deployment and source options，不勾选如下四项：
4. 从 .yml 脚本创建 pipeline
pipeline.yml 脚本内容如下：
apiVersion: v1
kind: BuildConfig
metadata:
name: myfirstpipeline
labels:
name: myfirstpipeline
annotations:
pipeline.alpha.openshift.io/uses: '[{"name": "myphp", "namespace": "", "kind": "DeploymentConfig"}]'
spec:
triggers:
-
type: GitHub
github:
secret: secret101
-
type: Generic
generic:
secret: secret101
runPolicy: Serial
source:
type: None
strategy:
type: JenkinsPipeline
jenkinsPipelineStrategy:
jenkinsfile: "node('maven') {\nstage 'build'\nopenshiftBuild(buildConfig: 'myphp', showBuildLogs: 'true')\nstage 'deploy'\nopenshiftDeploy(deploymentConfig: 'myphp')\nopenshiftScale(deploymentConfig: 'myphp',replicaCount: '2')\n}"
output:
resources:
postCommit:
执行后会发现在当前 project 中，创建并启动了 jenkins 和 jenkins-jnlp pod。
5. 选择 Builds -> Pipeline -> Start Build
查看 pipeline 构建过程，
点击 View log，登录 https://jenkins-applications.apps.example.com，查看构建日志
6. 访问 http://myphp-applications.apps.example.com/

参考《离线安装 OCP 3.4 之测试 PHP 应用》
点击展开 Show advanced routing, build, deployment and source options，不勾选如下四项：
- Automatically build a new image when the builder image changes
- Launch the first build when the build configuration is created
- New image is available
- Deployment configuration changes
