08 . Jenkins之SpringCloud微服务+Vue+Docker持续集成

简介

大致流程

/*
		1.开发人员每天把代码提交到Gitlab代码仓库
		2.jenkins从gitlab中拉取项目源码,编译并打包成war包,然后构建Docker镜像,将镜像上传到Harbor私有仓库
		3.jenkins发送ssh远程命令,让生产部署服务到Harbor私有仓库拉取镜像到本地,然后创建容器
		4.最后,用户就可以访问到容器
*/

部署Docker

安装必要系统工具和软件源

# 安装一些必要的系统工具
sudo yum install -y yum-utils device-mapper-persistent-data lvm2
# 添加软件源信息
# docker 官方源
sudo yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo

# 阿里云源
sudo yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo

安装并启动Docker-ce

# 安装前可以先更新 yum 缓存：
sudo yum makecache fast

# CentOS7安装 Docker-ce
yum -y install docker-ce        # CentOS 中安装
apt-get install docker-ce       # Ubuntu 中安装
pacman -S docker                # Arch 中安装
emerge --ask docker             # Gentoo 中安装

# 如果想安装特定版本的Docker-ce版本，先列出repo中可用版本，然后选择安装
yum list docker-ce --showduplicates |sort -r

yum install docker-ce-<VERSION STRING>
# 选择安装 docker-ce-18.06.1.ce
yum install docker-ce-18.06.1.ce -y

# Docker镜像加速
# 没有启动/etc/docker目录不存在，需要自己创建，docker启动也会自己创建
# 为了期望我们的镜像下载快一点，应该定义一个镜像加速器，加速器在国内
mkdir /etc/docker
vim /etc/docker/daemon.json
{
"registry-mirrors": ["https://registry.docker-cn.com"]
}

# 或者使用阿里云的
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

# 启动Docker后台服务
systemctl start docker && systemctl enable docker
systemctl daemon-reload                 # 守护进程重启

# 通过运行hello-world镜像，验证是否正确安装了docker，或者通过查看版本
docker run hello-world

docker使用

docker使用请看我前面写的docker blog

https://www.cnblogs.com/you-men/category/1789332.html

使用dockerfile制作微服务镜像

1.上传Eureka的微服务jar包到linux

2.编写Dockerfile

FROM openjdk:8-jdk-alpine
ARG JAR_FILE
COPY ${JAR_FILE} app.jar
EXPOSE 10086
ENTRYPOINT ["java","-jar","/app.jar"]

3.构建镜像

docker build --build-arg JAR_FILE=tensquare_eureka_server-1.0-SNAPSHOT.jar -t eureka:v1 .

4.查看镜像是否创建成功

docker images

5.创建容器

docker run -i --name=eureka -p 10086:10086 eureka:v1

部署配置Harbor

安装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

# 对二进制文件应用可执行权限：
sudo chmod +x /usr/local/bin/docker-compose
# 测试是否安装成功
docker-compose --version

解压安装配置harbor

# 解压
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

# 安装
./install

启动访问harbor

# 启动
docker-compose up -d 

# 停止
docker-compose stop 

# 重新启动
docker-compose restart

# 访问harbor
# IP:88
# 默认账户密码: admin/Harbor12345

创建项目

# Harbor的项目分为公有和私有的:
# 公有项目:  所有用户都可以访问,通常你存放公共镜像,默认有一个library公开项目
# 私有项目:  所有授权用户才可以访问,通常存放项目本身的镜像

创建用户

给项目分配用户

角色	权限说明
访客	对于指定项目拥有只读权限
开发人员	对于指定项目拥有读写权限
维护人员	对于指定项目拥有读写权限,创建Webhooks
项目管理员	除了读写权限,同时拥有用户管理/镜像扫描管理权限

以新用户登录Harbor

镜像上传Harbor

1. 给镜像打标签

docker tag nginx:latest 192.168.1.8/tensquare/nginx:v1

2. 将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. 登录harbor推送镜像

 docker login -u wunai -p xxxxx 192.168.1.8:88

 docker push 192.168.1.8:88/tensquare/nginx:v1

从Harbor下载镜像

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.先登录,再从Harbor下载镜像

 docker login -u wunai -p xxxxx 192.168.1.8:88
 docker pull 192.168.1.8:88/tensquare/nginx:v1

从GitHub拉取代码

创建GitLab后端项目

创建前端项目

上传代码就不演示了

配置Jenkins后端拉取项目

jenkinsfile2

//git凭证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('拉取代码') {
        checkout([$class: 'GitSCM', branches: [[name: "*/${branch}"]], doGenerateSubmoduleConfigurations: false, extensions: [], submoduleCfg: [], userRemoteConfigs: [[credentialsId: "${git_auth}", url: "${git_url}"]]])
   }
}

提交到SonarQube代码审查

jenkinsfile2

//git凭证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('拉取代码') {
        checkout([$class: 'GitSCM', branches: [[name: "*/${branch}"]], doGenerateSubmoduleConfigurations: false, extensions: [], submoduleCfg: [], userRemoteConfigs: [[credentialsId: "${git_auth}", url: "${git_url}"]]])
   }

   stage('代码审查') {
        //定义当前Jenkins的SonarQubeScanner工具
        def scannerHome = tool 'sonar-scanner'
        //引用当前JenkinsSonarQube环境
        withSonarQubeEnv('sonarqube') {
            sh """
                cd ${project_name}
         	    ${scannerHome}/bin/sonar-scanner
            """
        }
   	}
}

编译打包微服务工程

//git凭证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('拉取代码') {
        checkout([$class: 'GitSCM', branches: [[name: "*/${branch}"]], doGenerateSubmoduleConfigurations: false, extensions: [], submoduleCfg: [], userRemoteConfigs: [[credentialsId: "${git_auth}", url: "${git_url}"]]])
   }

   stage('代码审查') {
        //定义当前Jenkins的SonarQubeScanner工具
        def scannerHome = tool 'sonar-scanner'
        //引用当前JenkinsSonarQube环境
        withSonarQubeEnv('sonarqube') {
            sh """
                cd ${project_name}
         	    ${scannerHome}/bin/sonar-scanner
            """
        }
   	}

   	stage('编译,安装公共子工程') {
   		sh "mvn -f tensquare_common clean install"
   	}

   	stage('编译,打包微服务工程') {
   		sh "mvn -f ${project_name} clean package"
   	}
}

使用Dockerfile生成镜像

在每个微服务项目pom.xml加入dockerfile-maven-plugin插件

    <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>

每个微服务项目根目录建立dockerfile文件

#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凭证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('拉取代码') {
        checkout([$class: 'GitSCM', branches: [[name: "*/${branch}"]], doGenerateSubmoduleConfigurations: false, extensions: [], submoduleCfg: [], userRemoteConfigs: [[credentialsId: "${git_auth}", url: "${git_url}"]]])
   }

   stage('代码审查') {
        //定义当前Jenkins的SonarQubeScanner工具
        def scannerHome = tool 'sonar-scanner'
        //引用当前JenkinsSonarQube环境
        withSonarQubeEnv('sonarqube') {
            sh """
                cd ${project_name}
         	    ${scannerHome}/bin/sonar-scanner
            """
        }
   	}

   	stage('编译,安装公共子工程') {
   		sh "mvn -f tensquare_common clean install"
   	}

   	stage('编译,打包微服务工程') {
   		sh "mvn -f ${project_name} clean package dockerfile:build"
   	}
}

上传Harbor镜像仓库并拉取发布应用

创建harbor凭证

# 创建完成后再点进去将里面ID复制出来,然后放到Jenkinsfile里面
1d961bbc-82a1-41a2-b146-52bcaffe44f7

将harbor用户名和密码通过凭证和pipline转换达到隐藏用户名和密码的功能

上传Harbor镜像

//git凭证ID
def git_auth = "d04c1647-902a-4d18-b5df-36e5a69af120"

// 镜像版本号
def tag = "latest"

// Harbor的url地址
def harbor_url="192.168.1.8:88"

// 镜像库项目名称
def harbor_project = "tensquare"

// Harbor的登陆凭证
def harbor_auth = "1d961bbc-82a1-41a2-b146-52bcaffe44f7"

node {
   stage('拉取代码') {
        checkout([$class: 'GitSCM', branches: [[name: "*/${branch}"]], doGenerateSubmoduleConfigurations: false, extensions: [], submoduleCfg: [], userRemoteConfigs: [[credentialsId: "${git_auth}", url: "${git_url}"]]])
   }

   stage('代码审查') {
        //定义当前Jenkins的SonarQubeScanner工具
        def scannerHome = tool 'sonar-scanner'
        //引用当前JenkinsSonarQube环境
        withSonarQubeEnv('sonarqube') {
            sh """
                cd ${project_name}
         	    ${scannerHome}/bin/sonar-scanner
            """
        }
   	}

   	stage('编译,安装公共子工程') {
   		sh "mvn -f tensquare_common clean install"
   	}

   	stage('编译,打包微服务工程,上传镜像') {
   		sh "mvn -f ${project_name} clean package dockerfile:build"

   		// 定义镜像名称
   		def imageName = "${project_name}:${tag}"

   		// 对镜像打标签
   		sh "docker tag ${imageName} ${harbor_url}/${harbor_project}/${imageName}"

        //把镜像推送到Harbor
        withCredentials([usernamePassword(credentialsId: "${harbor_auth}", passwordVariable: 'password', usernameVariable: 'username')]) {

            //登录到Harbor
            sh "docker login -u ${username} -p ${password} ${harbor_url}"

            //镜像上传
            sh "docker push ${harbor_url}/${harbor_project}/${imageName}"

            sh "echo 镜像上传成功"
        }
   	}
}
