从零开始的CI/DI Jenkins集成docker+.NetCore自动化发布

环境介绍

Centos7.6版本

开始搭建

搭建Jenkins

1.安装Jenkins

wget -O /etc/yum.repos.d/jenkins.repo \
    https://pkg.jenkins.io/redhat-stable/jenkins.repo
rpm --import https://pkg.jenkins.io/redhat-stable/jenkins.io.key
yum upgrade
yum install epel-release java-11-openjdk-devel
yum install jenkins.noarch -y //安装
systemctl status jenkins.service//查看状态
systemctl start jenkins.service//启动

修改Jenkins配置文件
vim /etc/sysconfig/jenkins 修改JENKINS_USER=“jenkins” 修改为JENKINS_USER=“root”

2.访问Jenkins
http://101.35.80.206:8080/ http://IP:8080/
等待Jenkins初始化

命令行输入

cat /var/lib/jenkins/secrets/initialAdminPassword

将会得到初始化密码
输入input框即可初始化Jenkins

默认安装即可

创建一个默认用户

安装完成开始使用Jenkins吧！

开始使用Jenkins

配置证书

配置gitee账号

点击Manage Credentials

点击Jenkins

点击倒三角并点击Add credentials

选择Username with password

输入账号密码以及Id user pass Id

配置Jenkins插件

点击Manage Jenkins然后再点击Manage Plugins


这里安装以下插件

1. SSH Pipeline Steps
2. Gitee
3. Gogs

安装Docker

这里推荐使用阿里云的自动化安装脚本

Docker CE 镜像源站

curl -fsSL https://get.docker.com | bash -s docker --mirror Aliyun //安装
systemctl status docker //查看状态
//如果没有启动请使用
systemctl start docker //启动服务

groupadd docker
usermod -aG docker ${USER}
systemctl restart docker
systemctl restart jenkins

安装.Net5

我本机环境是Centos7.6 其他Linux系统请参考
https://docs.microsoft.com/en-us/dotnet/core/install/linux?WT.mc_id=dotnet-35129-website

rpm -Uvh https://packages.microsoft.com/config/centos/7/packages-microsoft-prod.rpm
yum install dotnet-sdk-5.0

nuget证书问题

dotnet dev-certs
cp /etc/pki/tls/cert.pem  /usr/local/openssl/cert.pem

创建一个项目

创建一个流水线项目

初始化项目并填上git地址

选择分支

注明Jenkinsfile文件地址

保存配置

配置163 STMP邮件服务器信息

进入Jenkins系统配置

找到E-mail Notification

配置STMP服务器，账号，授权码


这些东西在163邮箱中获取
https://email.163.com/

配置JenkinsFile文件

创建Jenkinsfile文件
注意！ 如果系统上有多个dotnet 需要使用绝对路径 比如 /usr/share/dotnet/dotnet 如果系统上只装了一个dotnet的话使用dotnet

def remote = [:]
remote.name = 'TService'
remote.host =  ''//服务器地址
remote.user = 'root'
remote.password = ''服务器密码
remote.allowAnyHosts = true
pipeline {
    agent any

    environment {
        RELEASE_PATH = "${WORKSPACE}/releases"
        COMMIT_ID = sh(returnStdout: true, script: 'git rev-parse HEAD')
        DOCKER_USERNAME = "" //docker hub账号
        DOCKER_PASSWORD = "" //docker hub密码
    }
    stages {
        stage('Build') {
            steps {
                echo 'Building...'
                sh "/usr/share/dotnet/dotnet build"
            }
        }
        stage('Test') {
            steps {
                echo 'Testing..'
            }
        }
        stage('Publish') {
            steps {
                echo 'Publish....'
                sh "/usr/share/dotnet/dotnet publish -c=Release -o=${RELEASE_PATH}/DevOps WebApplication1/WebApplication1.csproj"
                echo RELEASE_PATH
                writeFile(file: "${RELEASE_PATH}/DevOps/commit-${COMMIT_ID}.txt", text: "")
            }
        }
        stage('Docker Build') {
            steps {
                echo 'Docker Build...'
                sh "docker login -u ${DOCKER_USERNAME} -p ${DOCKER_PASSWORD}"
                sh "cp WebApplication1/Dockerfile ${RELEASE_PATH}/DevOps"
                sh "cd ${RELEASE_PATH}/DevOps && docker build -t ${DOCKER_USERNAME}/dev_ops:latest ."
                sh "docker push ${DOCKER_USERNAME}/dev_ops:latest"
            }
        }
        stage('Service Docker Run'){
            steps {
                script{
                    try {
                                echo "Service Docker Run...."
                                sshCommand remote: remote, command: "docker login -u ${DOCKER_USERNAME} -p ${DOCKER_PASSWORD}"
                                sshCommand remote: remote, command: "docker pull ${DOCKER_USERNAME}/dev_ops:latest"
                                sshCommand remote: remote, command: "docker stop dev_ops"
                                sshCommand remote: remote, command: "docker rm dev_ops"
                                sshCommand remote: remote, command: "docker run --name dev_ops -d -p 5003:80 ${DOCKER_USERNAME}/dev_ops"
                                sshCommand remote: remote, command: "docker logout"
                            } 
                            catch (Exception  e){
                                echo "Service Docker Run...."
                                sshCommand remote: remote, command: "docker login -u ${DOCKER_USERNAME} -p ${DOCKER_PASSWORD}"
                                sshCommand remote: remote, command: "docker pull ${DOCKER_USERNAME}/dev_ops:latest"
                                sshCommand remote: remote, command: "docker run --name dev_ops -d -p 5003:80 ${DOCKER_USERNAME}/dev_ops"
                                sshCommand remote: remote, command: "docker logout"
                            }
                }
         
            }
         
        }
        stage('Delete Publish Release') {
            steps {
                echo "Delete Files..."
                sh "rm -rf ${RELEASE_PATH}"
            }
        }
    }
    post {
       success {
             mail bcc: '', body: "如题", cc: '', from: ''//发送者邮箱, replyTo: '', subject: "发布成功", to: ''//接收者邮箱
       }

       failure {
              mail bcc: '', body: "如题1", cc: '', from: ''//发送者邮箱, replyTo: '', subject: "发布失败", to: ''//接收者邮箱
       }
   }
}

配置DockFile

DockFile文件地址

DockerFile文件内容

FROM mcr.microsoft.com/dotnet/aspnet:5.0
COPY . /app
WORKDIR /app
EXPOSE 80
EXPOSE 443
ENTRYPOINT ["dotnet", "WebApplication1.dll"]

配置完成后将代码Git push到仓库中

然后再Jenkins中开始构建发布

发布成功
