簡介
大致流程
/*
1.開發人員每天把程式碼提交到Gitlab程式碼倉庫
2.jenkins從gitlab中拉取專案原始碼,編譯並打包成war包,然後構建Docker映象,將映象上傳到Harbor私有倉庫
3.jenkins傳送ssh遠端命令,讓生產部署服務到Harbor私有倉庫拉取映象到本地,然後建立容器
4.最後,使用者就可以訪問到容器

SpringCloud微服務原始碼概述
/*
專案架構: 前後端分離
後端技術棧: SpringBoot+SpringCloud+SpringDatajpa(Spring全家桶)
*/
/*
微服務專案結構
tensquare_parent: 父工程,存放基礎配置
tensquare_common: 通用工程
tensquare_eureka_server: SpringCloud的Eureka註冊中心
tensquare_zull: SpringCloud的閘道器服務
tensquare: 基礎許可權認證中心,負責使用者認證(使用jwt認證)
tenquare_guathering: 一個簡單的業務模組,活動微服務相關邏輯
*/
/*
資料庫結構
tensquare_user: 使用者認證資料庫,存放使用者賬號資料,對應tensquare_admin_service微服務
tensquare_gathering: 活動微服務資料庫,對應tensquare_gathering微服務

部署Docker
安裝必要系統工具和軟體源
# 安裝一些必要的系統工具
sudo yum install -y yum-utils device-mapper-persistent-data lvm2
# 新增軟體源資訊
# docker 官方源
sudo yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
# 阿里雲源
sudo yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
安裝並啟動Docker-ce
# 安裝前可以先更新 yum 快取:
sudo yum makecache fast
# CentOS7安裝 Docker-ce
yum -y install docker-ce # CentOS 中安裝
apt-get install docker-ce # Ubuntu 中安裝
pacman -S docker # Arch 中安裝
emerge --ask docker # Gentoo 中安裝
# 如果想安裝特定版本的Docker-ce版本,先列出repo中可用版本,然後選擇安裝
yum list docker-ce --showduplicates |sort -r

# Docker映象加速
# 沒有啟動/etc/docker目錄不存在,需要自己建立,docker啟動也會自己建立
# 為了期望我們的映象下載快一點,應該定義一個映象加速器,加速器在國內
mkdir /etc/docker
vim /etc/docker/daemon.json
{
"registry-mirrors": ["https://registry.docker-cn.com"]
}
# 或者使用阿里雲的
sudo mkdir -p /etc/docker
sudo tee /etc/docker/daemon.json <<-'EOF'
{
"registry-mirrors": ["https://yj9iu9ne.mirror.aliyuncs.com"]
}
EOF
sudo systemctl daemon-reload
sudo systemctl restart docker
# 啟動Docker後臺服務
systemctl start docker && systemctl enable docker
systemctl daemon-reload # 守護程式重啟
# 通過執行hello-world映象,驗證是否正確安裝了docker,或者通過檢視版本

docker使用
docker使用請看我前面寫的docker blog
https://www.cnblogs.com/you-men/category/1789332.html
使用dockerfile製作微服務映象
1.上傳Eureka的微服務jar包到linux
2.編寫Dockerfile
FROM openjdk:8-jdk-alpine
ARG JAR_FILE
COPY ${JAR_FILE} app.jar
EXPOSE 10086
ENTRYPOINT ["java","-jar","/app.jar"]
3.構建映象
docker build --build-arg JAR_FILE=tensquare_eureka_server-1.0-SNAPSHOT.jar -t eureka:v1 .
4.檢視映象是否建立成功
docker images
5.建立容器
docker run -i --name=eureka -p 10086:10086 eureka:v1
部署配置Harbor
安裝docker-compose
curl -L "https://github.com/docker/compose/releases/download/1.22.0/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
# 對二進位制檔案應用可執行許可權:
sudo chmod +x /usr/local/bin/docker-compose
# 測試是否安裝成功
docker-compose --version
解壓安裝配置harbor
# 解壓
tar xf harbor-offline-installer-v1.9.2.tgz
mkdir /opt/harbor
mv harbor/* /opt/harbor
cd /opt/harbor
# 配置
vim harbor.yml
hostname: 192.168.1.8
port: 88
# 安裝
./install
啟動訪問harbor
# 啟動
docker-compose up -d
# 停止
docker-compose stop
# 重新啟動
docker-compose restart
# 訪問harbor
# IP:88
# 預設賬戶密碼: admin/Harbor12345
建立專案
# Harbor的專案分為公有和私有的:
# 公有專案: 所有使用者都可以訪問,通常你存放公共映象,預設有一個library公開專案
# 私有專案: 所有授權使用者才可以訪問,通常存放專案本身的映象
建立使用者
給專案分配使用者
角色 | 許可權說明 |
---|---|
訪客 | 對於指定專案擁有隻讀許可權 |
開發人員 | 對於指定專案擁有讀寫許可權 |
維護人員 | 對於指定專案擁有讀寫許可權,建立Webhooks |
專案管理員 | 除了讀寫許可權,同時擁有使用者管理/映象掃描管理許可權 |
以新使用者登入Harbor
映象上傳Harbor
1. 給映象打標籤
docker tag nginx:latest 192.168.1.8/tensquare/nginx:v1
2. 將Harbor地址加入到Docker信任列表
vim /etc/docker/daemon.json
{
"registry-mirrors": ["https://yj9iu9ne.mirror.aliyuncs.com"],
"insecure-registries": ["192.168.1.8:88"]
}
3. 登入harbor推送映象
docker login -u wunai -p xxxxx 192.168.1.8:88
docker push 192.168.1.8:88/tensquare/nginx:v1
從Harbor下載映象
1.修改docker配置
vim /etc/docker/daemon.json
{
"registry-mirrors": ["https://registry.docker-cn.com"],
"insecure-registries": ["192.168.1.8:88"]
}
2.先登入,再從Harbor下載映象
docker login -u wunai -p xxxxx 192.168.1.8:88
docker pull 192.168.1.8:88/tensquare/nginx:v1
從GitHub拉取程式碼
建立GitLab後端專案
建立前端專案
上傳程式碼就不演示了
配置Jenkins後端拉取專案
jenkinsfile2
//git憑證ID
def git_auth = "d04c1647-902a-4d18-b5df-36e5a69af120"
//git的url地址
def git_url = "git@192.168.1.4:youmen/tensquare_back.git"
node {
stage('拉取程式碼') {
checkout([$class: 'GitSCM', branches: [[name: "*/${branch}"]], doGenerateSubmoduleConfigurations: false, extensions: [], submoduleCfg: [], userRemoteConfigs: [[credentialsId: "${git_auth}", url: "${git_url}"]]])
}
}
提交到SonarQube程式碼審查
jenkinsfile2
//git憑證ID
def git_auth = "d04c1647-902a-4d18-b5df-36e5a69af120"
//git的url地址
def git_url = "git@192.168.1.4:youmen/tensquare_back.git"
node {
stage('拉取程式碼') {
checkout([$class: 'GitSCM', branches: [[name: "*/${branch}"]], doGenerateSubmoduleConfigurations: false, extensions: [], submoduleCfg: [], userRemoteConfigs: [[credentialsId: "${git_auth}", url: "${git_url}"]]])
}
stage('程式碼審查') {
//定義當前Jenkins的SonarQubeScanner工具
def scannerHome = tool 'sonar-scanner'
//引用當前JenkinsSonarQube環境
withSonarQubeEnv('sonarqube') {
sh """
cd ${project_name}
${scannerHome}/bin/sonar-scanner
"""
}
}
}
編譯打包微服務工程
//git憑證ID
def git_auth = "d04c1647-902a-4d18-b5df-36e5a69af120"
//git的url地址
def git_url = "git@192.168.1.4:youmen/tensquare_back.git"
node {
stage('拉取程式碼') {
checkout([$class: 'GitSCM', branches: [[name: "*/${branch}"]], doGenerateSubmoduleConfigurations: false, extensions: [], submoduleCfg: [], userRemoteConfigs: [[credentialsId: "${git_auth}", url: "${git_url}"]]])
}
stage('程式碼審查') {
//定義當前Jenkins的SonarQubeScanner工具
def scannerHome = tool 'sonar-scanner'
//引用當前JenkinsSonarQube環境
withSonarQubeEnv('sonarqube') {
sh """
cd ${project_name}
${scannerHome}/bin/sonar-scanner
"""
}
}
stage('編譯,安裝公共子工程') {
sh "mvn -f tensquare_common clean install"
}
stage('編譯,打包微服務工程') {
sh "mvn -f ${project_name} clean package"
}
}
使用Dockerfile生成映象
在每個微服務專案pom.xml加入dockerfile-maven-plugin外掛
<build>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
</plugin>
<plugin>
<groupId>com.spotify</groupId>
<artifactId>dockerfile-maven-plugin</artifactId>
<version>1.3.6</version>
<configuration>
<repository>${project.artifactId}</repository>
<buildArgs>
<JAR_FILE>target/${project.build.finalName}.jar</JAR_FILE>
</buildArgs>
</configuration>
</plugin>
</plugins>
</build>
每個微服務專案根目錄建立dockerfile檔案
#FROM java:8
FROM openjdk:8-jdk-alpine
ARG JAR_FILE
COPY ${JAR_FILE} app.jar
EXPOSE 10086
ENTRYPOINT ["java","-jar","/app.jar"]
配置jenkinsfile
//git憑證ID
def git_auth = "d04c1647-902a-4d18-b5df-36e5a69af120"
//git的url地址
def git_url = "git@192.168.1.4:youmen/tensquare_back.git"
node {
stage('拉取程式碼') {
checkout([$class: 'GitSCM', branches: [[name: "*/${branch}"]], doGenerateSubmoduleConfigurations: false, extensions: [], submoduleCfg: [], userRemoteConfigs: [[credentialsId: "${git_auth}", url: "${git_url}"]]])
}
stage('程式碼審查') {
//定義當前Jenkins的SonarQubeScanner工具
def scannerHome = tool 'sonar-scanner'
//引用當前JenkinsSonarQube環境
withSonarQubeEnv('sonarqube') {
sh """
cd ${project_name}
${scannerHome}/bin/sonar-scanner

}
}
stage('編譯,安裝公共子工程') {
sh "mvn -f tensquare_common clean install"
}
stage('編譯,打包微服務工程') {
sh "mvn -f ${project_name} clean package dockerfile:build"
}
}
上傳Harbor映象倉庫並拉取釋出應用
建立harbor憑證
# 建立完成後再點進去將裡面ID複製出來,然後放到Jenkinsfile裡面
1d961bbc-82a1-41a2-b146-52bcaffe44f7
將harbor使用者名稱和密碼通過憑證和pipline轉換達到隱藏使用者名稱和密碼的功能
