Jenkins安装 docker
Jenkins是一个开源的持续集成工具,它可以帮助你在软件开发过程中自动构建、测试和部署应用程序。要将Docker集成到Jenkins中,你需要完成以下几个步骤:
1. **安装Jenkins**:
- 访问Jenkins官网下载适用于你的操作系统的安装包,如`https://jenkins.io/download/`。
- 按照指示安装,可以选择图形化界面或命令行安装。
2. **启动Jenkins服务**:
安装完成后,打开浏览器访问默认地址(通常是`http://localhost:8080/`),按照向导设置管理员账户并初始化服务器。
3. **安装Docker插件**:
登录Jenkins管理界面后,在“管理”->“系统设置”->“插件管理”页面搜索“Docker Pipeline”,找到官方的“Docker Pipeline”插件并安装。
4. **配置Docker环境**:
- 需要确保你的机器上已经安装了Docker,并且Docker daemon正在运行。
- 在Jenkins中,新建一个自由风格项目或者选择支持Docker的工作流程(如Pipeline),在项目的配置文件(`.groovy`或`.yaml`)中添加对Docker的支持。
5. **编写Dockerfile**:
如果你想自动化构建镜像,需要创建一个Dockerfile,指定基础镜像、安装依赖等。
6. **创建Docker构建脚本**:
使用`docker build`或`docker-compose`命令行构建你的Docker镜像,或者在Jenkinsfile中编写相应的管道(pipeline steps)来执行这些操作。
7. **触发构建**:
设置好构建触发条件后(比如提交代码或定时构建),保存并触发一个新的构建任务,Jenkins会利用Docker插件来构建、推送到仓库或直接运行容器。

Jenkins Pipeline is a tool that allows you to define and automate your CI/CD workflows as code. Docker is a platform that allows you to build, run, and manage containerized applications.
When using Jenkins Pipeline with Docker, you can define your build, test, and deployment steps within the pipeline code and use Docker containers to execute those steps. This allows for greater portability and consistency across different environments.
To use Docker within a Jenkins Pipeline, you will need to have the Docker plugin installed on your Jenkins instance. You can then define your pipeline stages to include steps such as building a Docker image, running tests within a Docker container, and deploying your application to a Docker registry.
Here is an example pipeline code that uses Docker:
```
pipeline {
agent {
docker {
image 'node:12-alpine'
}
}
stages {
stage('Build') {
steps {
sh 'npm install'
sh 'npm run build'
}
}
stage('Test') {
steps {
sh 'npm run test'
}
}
stage('Deploy') {
steps {
withCredentials([usernamePassword(credentialsId: 'dockerhub', usernameVariable: 'DOCKER_USERNAME', passwordVariable: 'DOCKER_PASSWORD')]) {
sh 'docker login -u $DOCKER_USERNAME -p $DOCKER_PASSWORD'
}
sh 'docker build -t myapp:latest .'
sh 'docker push myapp:latest'
}
}
}
}
```
This pipeline uses the `node:12-alpine` Docker image as the build agent, installs dependencies, runs tests, and finally deploys the application to a Docker registry using credentials stored in Jenkins.
