docker部署单节点Jenkins实现一个自由风格的devops

以你之姓@ 2024-03-23 15:11 71阅读 0赞

## 一、docker compose安装Jenkins ##

### 1、编写docker-compose.yml文件 ###

新建/usr/local/docker/jenkins包，在此包下新建docker-compose.yml文件

注：最好是在/usr/local下新建，之前在/下新建，项目打包报错

> version: '3.1'  
> services:  
> jenkins:  
> image: jenkins/jenkins:2.350-jdk8  
> container\_name: jenkins  
> ports:  
> \- 8080:8080  
> \- 50000:50000  
> volumes:  
> \- ./data/:/var/jenkins\_home/

### 2、 启动容器 ###

> docker-compose up -d

第一次启动后，会发现抛出一个permission的错误，在写入log日志到/var/jenkins\_home/时，没有权限，因为宿主机的数据源不允许其他用户写入。给数据卷data复制w权限：

> chmod a+w data

再次启动容器

> docker-compose up -d

需要稍微等一会，看到Jenkins的首页

首页的密码需要从容器的日志中查看。

> docker logs ![382e89578a1d4f469d22ee55adfbea11.png][]

输入密码后，继续，然后需要指定选择安装插件的方式

安装插件（听天由命）

![37e566eedd2543dfa3266fbd7341b914.png][]

指定用户

![0b0414757ed54028a47b78994dd8ba9b.png][]

最终查看到Jenkins的首页

## 二、Jenkins安装git、ssh插件 ##

在系统管理-插件管理，添加需要的插件

1、安装Git Parameter插件

2、安装publish over ssh插件

点install without restart

![89eb6edf800546329b4419f5a4c2062b.png][]

配置ssh，系统管理-系统配置

![297cb9db4a794160b6c26c247e7befe6.png][]

Remote Directory为传输到的包路径

## 三、Jenkins配置jdk、maven ##

将maven和jdk8的tar.gz文件放入/usr/local/docker/jenkins/data文件中

![f5ae5944a173475da2dfde31984b3fe1.png][]

解压并修改名称

> tar -zxvf apache-maven-3.9.1-bin.tar.gz
> 
> mv apache-maven-3.9.1 maven-3.9.1

> tar -zxvf jdk-8u371-linux-x64.tar.gz
> 
> mv jdk1.8.0\_371 jdk8

配置Maven的settings.xml（在conf文件中）

<mirror>  
        <id>alimaven</id>  
        <name>aliyun maven</name>  
        <url>http://maven.aliyun.com/nexus/content/groups/public/</url>
        <mirrorOf>central</mirrorOf>          
    </mirror>
    
    <profile>
        <id>jdk-1.8</id>
        <activation>
            <activeByDefault>true</activeByDefault>
            <jdk>1.8</jdk>
        </activation>
        <properties>
            <maven.compiler.source>1.8</maven.compiler.source>
            <maven.compiler.target>1.8</maven.compiler.target>
            <maven.compiler.compilerVersion>1.8</maven.compiler.compilerVersion>
        </properties>        
    </profile>

将jdk和maven配置到Jenkins中，在系统配置-全局工具配置

注：设置路径是不要忘了最前面的/

![659fc17dee4f417888083a2b02e1812c.png][]

点击应用保存

## 四、新建任务进行打包测试 ##

选择第一个，点击确定

![140eecb154d144919e2b98e90da9b745.png][]

配置代码仓库

![4db437d7cd9443bca2261940a0e66c4e.png][]

配置maven

![754dcacb096943f58c5d22633a897f35.png][]

点击立即构建

![1ab68633301b47adb023e3ba381822ce.png][]

构建的jar包在workspace包下

![10aac13686a14704aef3529de40689e5.png][]

## 五、部署项目 ##

项目中和src同级新建docker包，报下新建docker-compose.yml和Dockerfile文件

docker-compose.yml文件

>     version: '3.1'
>     services:
>       filter-demo:
>         build: ./
>         image: filter-demo:v1.0.0
>         container_name: filter-demo
>         ports:
>           - 8081:8081

Dockerfile文件

>     FROM eclipse/centos_jdk8
>     COPY filter-demo-0.0.1-SNAPSHOT.jar /usr/local/
>     WORKDIR /usr/local/
>     CMD java -jar filter-demo-0.0.1-SNAPSHOT.jar

去任务配置中添加构建后配置

![e49e2f2f4a274ead8e2468660d77ea95.png][]

重新构建，成功后测试接口
