- Pipeline流水線介紹
(1) Jenkins Pipeline(或者簡稱為“Pipeline”)是一套外掛,支援在 Jenkins 中實施和整合持續交付流水線。
持續交付(CD)流水線是將軟體從版本控制釋出到使用者和客戶的過程的自動化表達。對軟體的每一次改變(在原始碼控制中提交)都會在釋出過程中經歷一個複雜的過程。這個過程包括以可靠和可重複的方式構建軟體,以及通過測試和部署的多個階段來推進構建的軟體(稱為“構建”)。
Pipeline 提供了一套可擴充套件的工具,用於通過 Pipeline domain-specific language(DSL)語法將交付流水線“作為程式碼”建模。
Jenkins Pipeline 的定義寫在稱為 Jenkinsfile 的文字檔案中,這個檔案可以提交到專案的程式碼控制倉庫。這是“Pipeline-as-code”的基礎。 將 CD 流水線作為應用程式的一部分進行版本控制,並像任何其他程式碼一樣進行審查。
(2) 建立 Jenkinsfile 檔案並且提交到版本控制有下面幾個好處:
對所有的 branches 和 pull 請求自動建立 Pipeline。 Pipeline 上的程式碼審查/迭代(along with the remaining source code)。 稽核追蹤 Pipeline Pipeline 的單一真實來源,可由專案的多個成員檢視和編輯。
雖然用於定義 Pipeline 的語法無論是在 Web UI 中還是在 Jenkinsfile 中是相同的,但在 Jenkinsfile 中定義 Pipeline 並提交到原始碼控制中通常被認為是最佳實踐。
(3) Pipeline的幾個基本概念:
Stage: 階段,一個Pipeline可以劃分為若干個Stage,每個Stage代表一組操作。注意,Stage是一個邏輯分組的概念,可以跨多個Node。 Node: 節點,一個Node就是一個Jenkins節點,或者是Master,或者是Agent,是執行Step的具體執行期環境。 Step: 步驟,Step是最基本的操作單元,小到建立一個目錄,大到構建一個Docker映象,由各類Jenkins Plugin提供。

建立一個基於Pipeline流水線的專案

新增專案Git引數化構建
node:代表單臺伺服器的節點 -
Pipeline指令碼語法架構介紹
#Pipeline指令碼語法架構
node ('slave節點名') { #被操控的節點伺服器
def 變數 #def可以進行變數宣告
stage('階段名A'){ #流水線階段一
執行步驟A
執行步驟B
執行步驟C
}
stage('階段名B'){ #流水線階段二
執行步驟A
執行步驟B
執行步驟C
}
stage('階段名C'){ #流水線階段三
執行步驟A
執行步驟B
執行步驟C
}
}
#流水線模板指令碼
node {
def mvnHome
stage('Preparation') { // for display purposes
// Get some code from a GitHub repository
git 'https://github.com/jglick/simple-maven-project-with-tests.git'
// Get the Maven tool.
// ** NOTE: This 'M3' Maven tool must be configured
// ** in the global configuration.
mvnHome = tool 'M3'
}
stage('Build') {
// Run the maven build # “//” 註釋
if (isUnix()) {
sh "'${mvnHome}/bin/mvn' -Dmaven.test.failure.ignore clean package"
} else {
bat(/"${mvnHome}\bin\mvn" -Dmaven.test.failure.ignore clean package/)
}
}
stage('Results') {
junit '**/target/surefire-reports/TEST-*.xml'
archive 'target/*.jar'
}
}
- 利用Pipeline Syntax,編寫Pipeline Script並構建
(1)進入Pipeline Syntax
(2)通過指令碼程式碼生成器,生成Pipeline指令碼程式碼
(3)將生成的程式碼複製到流水線指令碼相應步驟的stage函式裡
(4)開始構建Pipeline專案
[[email protected] workspace]# cd /test/
[[email protected] test]# cd app/
[[email protected] app]# ls
test.txt
[[email protected] app]# git remote -v

[[email protected] app]# cd /var/lib/jenkins/
[[email protected] jenkins]# cd workspace/
- 從遠端倉庫下載Pipeline Script,並構建
(1)在Git伺服器上建立一個存放Pipeline指令碼的倉庫

(2)在jenkins伺服器上,往遠端倉庫提交一個Pipeline指令碼。

- 建立一個Pipeline流水線專案並進行引數化構建
流水線一般情況下是用在線上環境,測試環境一般不用流水線,因為資料經常變更;測試環境不支援Git引數化構建,而線上環境只拉取master。
由於我們仍舊打算將pipeline指令碼放在遠端Git倉庫裡,因此我們需要從遠端Git倉庫拉取Pipeline指令碼,所以,引數化構建不支援Git的引數化。我們只能使用字元結構的引數化構建。
- 下載用於自動化釋出的PHP原始碼wordpress原始碼包,並上傳遠端git倉庫

- 設定分散式構建的slave管理節點
我們計劃利用分散式構建的方式,啟動pipeline的流水線專案釋出
slave管理節點就設定為需要用於釋出專案的Web伺服器
(1) 新增用於連線slave代理節點的SSH證書
(2) 新增並設定slave管理從節點
(3) slave從節點安裝java環境,並啟動jenkins的slave管理節點
#解壓安裝jdk

利用從節點遠端部署Web伺服器(通過SSH方式實現)
- 通過SSH分發指令碼
- 通過SSH直接下命令
- 安裝SSH Pipeline Steps外掛(使SSH主持流水線)
通過主Jenkins伺服器向從節點NginxWeb01下任務,讓從節點NginxWeb01通過SSH的方式向NginxWeb02和NginxWeb03伺服器分發指令碼;把指令碼用scp過去之後覆蓋;用流水線指令碼把程式碼發過去,使本地指令碼遠端啟用並執行在對方電腦中
