业务的简称为demo,微服务架构。N多个微服务。服务命名:业务简称-应用名称-类型(demo-hello-service)。特性分支开发,版本分支发布。每个需求(任务/故事)对应一个特性分支。每个发布(release)对应一个版本分支。

1.需求与代码管理
 Jira作为需求和缺陷管理,采用Scrum开发方法,jira中的项目名称与业务简称一致(demo)。Gitlab作为版本控制系统,每个Group对应一个业务,每个微服务对应一个代码库。
需求与代码关联:在jira中创建一个任务/故事,关联模块后自动在该模块创建一个以ISSUE(任务/故事)ID的特性分支。此时的模块等同于每个微服务的项目(代码库)名称。以下面图中为例:我们在demo项目中创建了一个模块demo-hello-service,其实对应的就是Gitlab代码库中demo组的demo-hello-service服务。
特性分支:创建好每个模块后,就可以实现需求与代码关联。例如:我们在Jira项目demo中创建一个问题,类型为故事(不受限制可为其他),重点是需要将改故事关联到模块(只有关联到模块,我们才能通过接口得知哪个问题关联的哪个代码库)。
版本分支:当特性分支开发完成以及测试验证完成后,基于主干分支创建一个版本分支,然后将所有的特性分支合并到版本分支。此时可以通过Jira中创建一个发布版本,然后问题关联发布版本(此动作表示该特性分支已经通过验证,可以合并)。自动完成版本分支的创建和特性分支到版本分支的合并请求。
2. 配置过程
 需求与代码库关联,主要用到的工具链为: Jira + GitLab + Jenkins。Jira负责创建需求,配置webhook。Jenkins负责接收Jira webhook请求,然后通过接口实现GitLab项目分支创建。
特性分支自动化:当我们在jira上面创建了问题,此时会通过Jira的webhook触发对应的Jenkins作业,该Jenkins作业通过解析Jira webhook传递的数据,找到问题名称和模块名称。调用GitlabAPI 项目查询接口,根据模块名称找到代码库。调用GitLabAPI 分支创建接口,根据问题名称基于主干分支创建一个特性分支。任务结束。
版本分支自动化:Jira创建发布版本,Issue关联版本。自动在gitlab代码库基于master创建版本分支,并开启特性分支到版本分支的合并请求。
2.1 准备工作
 在Jenkins, 创建一个Pipeline 作业并配置GenericTrigger 触发器,接收JiraWebhook数据。projectKey 参数表示Jira项目名称,webHookData 参数为Jira webhook的所有数据。token 是触发器的触发token,这里默认采用的作业名称(作业名称要唯一)。
- triggers {
 - GenericTrigger( causeString: 'Trigger By Jira Server -->>>>> Generic Cause',
 - genericRequestVariables: [[key: 'projectKey', regexpFilter: '']],
 - genericVariables: [[defaultValue: '', key: 'webHookData', regexpFilter: '', value: '$']],
 - printContributedVariables: true,
 - printPostContent: true,
 - regexpFilterExpression: '',
 - regexpFilterText: '',
 - silentResponse: true,
 - token: "${JOB_NAME}"
 - )
 
在Jira项目中配置Webhook,勾选触发事件填写触发URL。http://jenkins.idevops.site/generic-webhook-trigger/invoke?token=demo-jira-service&projectKey=${project.key} (这个地址是jenkins Generictrigger生成的,这里不做过多的介绍)
Jira webhook数据参考, 这些参数可以在Jenkinsfile中通过readJSON格式化,然后获取值。
- response = readJSON text: """${webHookData}"""
 - println(response)
 - //获取webhook的事件类型
 - env.eventType = response["webhookEvent"]
 
- {
 - "timestamp":1603087582648,
 - "webhookEvent":"jira:issue_created",
 - "issue_event_type_name":"issue_created",
 - "user":Object{...},
 - "issue":{
 - "id":"10500",
 - "self":"http://192.168.1.200:8050/rest/api/2/issue/10500",

 - "description":"",
 - "iconUrl":"http://192.168.1.200:8050/images/icons/issuetypes/story.svg",
 - "name":"故事",
 - "subtask":false

 - "id":"10200",

 - "description":"demo-hello-service应用"
 - }
 - ],
