一、实验

1.环境

（1）主机

表1 主机

主机	架构	版本	IP	备注
master1	K8S master节点	1.20.6	192.168.204.180	jenkins slave （从节点）
	jira	9.12.1	192.168.204.180:8801
node1	K8S node节点	1.20.6	192.168.204.181
node2	K8S node节点	1.20.6	192.168.204.182
jenkins	jenkins主节点	2.414.2	192.168.204.15:8080	gitlab runner （从节点）
gitlab	gitlab 主节点	12.10.14	192.168.204.8:82	jenkins slave （从节点）
	sonarqube	9.6	192.168.204.8:9000

（2）查看K8集群状态

# kubectl get node

2.GitLab 查看项目

（1） GitLab查看后端项目（项目编号为19）

（2）GitLab查看前端项目（项目编号为20）

3.Jira新建模块

（1）查询已有模块（前端项目）

（2）新建后端项目模块

（3）再次查看模块

4. Jira 通过Webhook 触发Jenkins流水线

（1）Jenkins新建流水线

（2）配置触发器

（3）拿到Webhook 触发地址

http://JENKINS_URL/generic-webhook-trigger/invoke

（4）拿到携带TOKEN的请求参数

 /invoke?token=TOKEN_HERE

（5）Jira配置网络钩子

（6）完成创建

（7）新建问题

（8）Jenkins流水线成功运行

（9）再次新建问题

（10）Jenkins流水线成功运行

（11）修改Jenkins流水线配置

pipeline {agent anystages {stage('Hello') {steps {echo "${webhookData}"}}}
}

（12）拿到webhook数据

（13）JSON转码

（14）拿到关键数据

1）用于创建gitlab 项目名称   
issue.fields.components 2） 用于gitlab 分支名称   
issue.key3）用于gitlab 项目组名称  
issue.fields.project.name

（15）Postman测试，获取项目id

http://192.168.204.8:82/api/v4/projects?search=devops03-devops-service

(16)Postman测试创建分支

http://192.168.204.8:82/api/v4/projects/20/repository/branches?branch=newbranch&ref=master

（17）GitLab前端项目成功创建分支

3.Jira 远程触发 Jenkins 实现更新 GitLab 分支

（1）Jenkins修改流水线代码

webhookData = readJSON text:  "${webhookData}"//jira 事件
jiraEvent = webhookData.webhookEvent
jiraProjectName = webhookData.issue.fields.project.name// 获取gitlab参数
gitlabProjects = []
gitlabBranchName = webhookData.issue.key
gitlabGroupName =  jiraProjectNamefor (i in webhookData.issue.fields.components){gitlabProjects.add(i["name"])
}//描述信息
currentBuild.description = "Trigger by ${jiraEvent} \n project: ${gitlabProjects} \n branch: ${gitlabBranchName}"pipeline {agent { label "build" }stages {stage("Process") {steps {script {println(gitlabProjects)println(gitlabBranchName)projectIds = GetProjectsId(gitlabGroupName,gitlabProjects)switch(jiraEvent) {case "jira:issue_created":println(projectIds)for (id in projectIds){CreateBranch(id,gitlabBranchName,"master")}breakdefault:println(error)break}}}}}
}// 创建分支
def CreateBranch(projectId,newBranchName,sourceBranchName){apiUrl = "projects/${projectId}/repository/branches?branch=${newBranchName}&ref=${sourceBranchName}"response =  HttpReq('POST', apiUrl, "")
}// 获取所有项目id
def GetProjectsId(gitlabGroupName,gitlabProjects){gitlabProjectIds = []for (project in gitlabProjects){id = GetProjectId(gitlabGroupName,project)if (id != 0){gitlabProjectIds.add(id)}}return gitlabProjectIds
}// 根据项目名称获取项目iddef GetProjectId(groupName,projectName){apiUrl = "projects?search=${projectName}"response =  HttpReq('GET', apiUrl, "")response =  readJSON text: response.content - "\n"for (i in response){if (i["path_with_namespace"] == "${groupName}/${projectName}"){return i["id"]}}
}// 封装HTTP
def HttpReq(reqType, reqUrl,reqBody ){def gitServer = "http://192.168.204.8:82/api/v4"withCredentials([string(credentialsId: '02dce3ff-4e46-4de2-b079-5dd6093d4f64', variable: 'GITLABTOKEN')]) {response = httpRequest acceptType: 'APPLICATION_JSON_UTF8',consoleLogResponseBody: true,contentType: 'APPLICATION_JSON_UTF8',customHeaders: [[maskValue: false, name: 'PRIVATE-TOKEN', value: "${GITLABTOKEN}"]],httpMode: "${reqType}",url: "${gitServer}/${reqUrl}",wrapAsMultipart: false,requestBody: "${reqBody}"}return response
}

(2) Jira 新建问题更新前端项目分支

（3）Jenkins运行成功,出现相关描述信息

（4）GitLab查看前端项目新增分支

（5）Jira 新建问题，实现同时更新前后端项目分支

（6）成功触发Jenkins流水线

（7）GitLab查看前端项目新增分支

（8）GitLab查看后端项目新增分支

（9）优化Jenkins流水线代码，防止GitLab 同一项目fork问题

webhookData = readJSON text:  "${webhookData}"//jira 事件
jiraEvent = webhookData.webhookEvent
jiraProjectName = webhookData.issue.fields.project.name// 获取gitlab参数
gitlabProjects = []
gitlabBranchName = webhookData.issue.key
gitlabGroupName =  jiraProjectNamefor (i in webhookData.issue.fields.components){gitlabProjects.add(i["name"])
}//描述信息
currentBuild.description = "Trigger by ${jiraEvent} \n project: ${gitlabProjects} \n branch: ${gitlabBranchName}"pipeline {agent { label "build" }stages {stage("Process") {steps {script {println(gitlabProjects)println(gitlabBranchName)projectIds = GetProjectsId(gitlabGroupName,gitlabProjects)switch(jiraEvent) {case "jira:issue_created":println(projectIds)for (id in projectIds){CreateBranch(id,gitlabBranchName,"master")}breakdefault:println(error)break}}}}}
}// 创建分支
def CreateBranch(projectId,newBranchName,sourceBranchName){try {apiUrl = "projects/${projectId}/repository/branches?branch=${newBranchName}&ref=${sourceBranchName}"response =  HttpReq('POST', apiUrl, "")}catch(Exception e){println(e)}
}// 获取所有项目id
def GetProjectsId(gitlabGroupName,gitlabProjects){gitlabProjectIds = []for (project in gitlabProjects){id = GetProjectId(gitlabGroupName,project)if (id != 0){gitlabProjectIds.add(id)}}return gitlabProjectIds
}// 根据项目名称获取项目iddef GetProjectId(groupName,projectName){apiUrl = "projects?search=${projectName}"response =  HttpReq('GET', apiUrl, "")response =  readJSON text: response.content - "\n"if (response.size() > 1){for (i in response){if (i["path_with_namespace"] == "${groupName}/${projectName}"){return i["id"]}}}else {return  response[0]["id"]}}// 封装HTTP
def HttpReq(reqType, reqUrl,reqBody ){def gitServer = "http://192.168.204.8:82/api/v4"withCredentials([string(credentialsId: '02dce3ff-4e46-4de2-b079-5dd6093d4f64', variable: 'GITLABTOKEN')]) {response = httpRequest acceptType: 'APPLICATION_JSON_UTF8',consoleLogResponseBody: true,contentType: 'APPLICATION_JSON_UTF8',customHeaders: [[maskValue: false, name: 'PRIVATE-TOKEN', value: "${GITLABTOKEN}"]],httpMode: "${reqType}",url: "${gitServer}/${reqUrl}",wrapAsMultipart: false,requestBody: "${reqBody}"}return response
