業(yè)務(wù)的簡稱為demo，微服務(wù)架構(gòu)。N多個微服務(wù)。服務(wù)命名：業(yè)務(wù)簡稱-應(yīng)用名稱-類型（demo-hello-service）。特性分支開發(fā)，版本分支發(fā)布。每個需求（任務(wù)/故事）對應(yīng)一個特性分支。每個發(fā)布（release）對應(yīng)一個版本分支。
1.需求與代碼管理
Jira作為需求和缺陷管理，采用Scrum開發(fā)方法，jira中的項目名稱與業(yè)務(wù)簡稱一致（demo）。Gitlab作為版本控制系統(tǒng)，每個Group對應(yīng)一個業(yè)務(wù)，每個微服務(wù)對應(yīng)一個代碼庫。
需求與代碼關(guān)聯(lián)：在jira中創(chuàng)建一個任務(wù)/故事，關(guān)聯(lián)模塊后自動在該模塊創(chuàng)建一個以ISSUE（任務(wù)/故事）ID的特性分支。此時的模塊等同于每個微服務(wù)的項目（代碼庫）名稱。以下面圖中為例：我們在demo項目中創(chuàng)建了一個模塊demo-hello-service，其實對應(yīng)的就是Gitlab代碼庫中demo組的demo-hello-service服務(wù)。
特性分支：創(chuàng)建好每個模塊后，就可以實現(xiàn)需求與代碼關(guān)聯(lián)。例如：我們在Jira項目demo中創(chuàng)建一個問題，類型為故事（不受限制可為其他），重點是需要將改故事關(guān)聯(lián)到模塊（只有關(guān)聯(lián)到模塊，我們才能通過接口得知哪個問題關(guān)聯(lián)的哪個代碼庫）。
版本分支：當(dāng)特性分支開發(fā)完成以及測試驗證完成后，基于主干分支創(chuàng)建一個版本分支，然后將所有的特性分支合并到版本分支。此時可以通過Jira中創(chuàng)建一個發(fā)布版本，然后問題關(guān)聯(lián)發(fā)布版本（此動作表示該特性分支已經(jīng)通過驗證，可以合并）。自動完成版本分支的創(chuàng)建和特性分支到版本分支的合并請求。
2. 配置過程
需求與代碼庫關(guān)聯(lián)，主要用到的工具鏈為: Jira + GitLab + Jenkins。Jira負(fù)責(zé)創(chuàng)建需求，配置webhook。Jenkins負(fù)責(zé)接收J(rèn)ira webhook請求，然后通過接口實現(xiàn)GitLab項目分支創(chuàng)建。
特性分支自動化：當(dāng)我們在jira上面創(chuàng)建了問題，此時會通過Jira的webhook觸發(fā)對應(yīng)的Jenkins作業(yè)，該Jenkins作業(yè)通過解析Jira webhook傳遞的數(shù)據(jù)，找到問題名稱和模塊名稱。調(diào)用GitlabAPI 項目查詢接口，根據(jù)模塊名稱找到代碼庫。調(diào)用GitLabAPI 分支創(chuàng)建接口，根據(jù)問題名稱基于主干分支創(chuàng)建一個特性分支。任務(wù)結(jié)束。
版本分支自動化：Jira創(chuàng)建發(fā)布版本，Issue關(guān)聯(lián)版本。自動在gitlab代碼庫基于master創(chuàng)建版本分支，并開啟特性分支到版本分支的合并請求。
2.1 準(zhǔn)備工作
在Jenkins， 創(chuàng)建一個Pipeline 作業(yè)并配置GenericTrigger 觸發(fā)器，接收J(rèn)iraWebhook數(shù)據(jù)。projectKey 參數(shù)表示Jira項目名稱，webHookData 參數(shù)為Jira webhook的所有數(shù)據(jù)。token 是觸發(fā)器的觸發(fā)token，這里默認(rèn)采用的作業(yè)名稱（作業(yè)名稱要唯一）。
- 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項目中配置Webhook，勾選觸發(fā)事件填寫觸發(fā)URL。http://jenkins.idevops.site/generic-webhook-trigger/invoke?token=demo-jira-service&projectKey=${project.key} (這個地址是jenkins Generictrigger生成的，這里不做過多的介紹)
Jira webhook數(shù)據(jù)參考， 這些參數(shù)可以在Jenkinsfile中通過readJSON格式化，然后獲取值。
- response = readJSON text: """${webHookData}"""
- println(response)
- //獲取webhook的事件類型
- env.eventType = response["webhookEvent"]
- {
- "timestamp":1603087582648,
