Openshift E02 部署Jenkins服务

OpenShift 项目默认提供了两个Jenkins部署模板, Jenkins-ephemeral 和 Jenkins-persistent

• Jenkins-ephemeral 模板部署的Jenkins服务的数据在容器退出后将丢失，适合测试使用；

• Jenkins-persistent 模板部署需要持久化卷的支持，其部署的Jenkins 服务的数据可以被持久化。

这里有很多官方的案例源码： https://github.com/openshift/origin/tree/v1.3.0/examples

oc login -u developer https://192.168.99.109:8443

# create a new project, name: ci
oc new-project ci

# Create a template, 
oc create -f https://raw.githubusercontent.com/openshift/origin/v1.3.0/examples/jenkins/jenkins-ephemeral-template.json 

# Get template
oc get template
NAME                DESCRIPTION                                       PARAMETERS        OBJECTS
jenkins-ephemeral   Jenkins service, without persistent storage....   6 (1 generated)   6

#
➜  ~ oc policy add-role-to-user edit -z default

--> Deploying template "ci/jenkins-ephemeral" to project ci

     jenkins-ephemeral
     ---------
     Jenkins service, without persistent storage.
     WARNING: Any data stored will be lost upon pod destruction. Only use this template for testing

     A Jenkins service has been created in your project.  The username/password are admin/welcome.  The tutorial at https://github.com/openshift/origin/blob/master/examples/jenkins/README.md contains more information about using this template.

     * With parameters:
        * Jenkins Service Name=jenkins
        * Jenkins JNLP Service Name=jenkins-jnlp
        * Jenkins Password=welcome
        * Memory Limit=512Mi
        * Jenkins ImageStream Namespace=openshift
        * Jenkins ImageStreamTag=jenkins:latest

--> Creating resources ...
    route.route.openshift.io "jenkins" created
    deploymentconfig.apps.openshift.io "jenkins" created
    serviceaccount "jenkins" created

    service "jenkins" created
--> Success
    Access your application via route 'jenkins-ci.192.168.99.109.nip.io'
    Run 'oc status' to view your app.

部署失败了，💔

oc delete all -l app=jenkins-ephemeral
pod "jenkins-1-6k7s6" deleted
replicationcontroller "jenkins-1" deleted
service "jenkins" deleted
service "jenkins-jnlp" deleted
deploymentconfig.apps.openshift.io "jenkins" deleted
route.route.openshift.io "jenkins" deleted

不能删除 serviceaccounts

oc delete serviceaccounts -l app=jenkins-ephemeral
oc delete rolebindings.authorization.openshift.io jenkins_edit

删除干净后，可以用命令 oc get all -o wide 验证

再来一次

oc new-app --template=jenkins-ephemeral --param=JENKINS_PASSWORD=welcome123
