构建流水线

1、安装docker

2、下载镜像

docker pull centos:7

3、构建基础镜像

Dockerfile-centos7

FROM centos:7
LABEL maintainer=haogeoyes
RUN yum -y install wget && cd /etc/yum.repos.d/ && wget http://mirrors.aliyun.com/repo/Centos-7.repo

docker build -t centos7:v1 .

4、安装java

docker build -t java:v1 -f Dockerfile-java1.8 .

FROM centos:v1
LABEL maintainer=haogeoyes
RUN yum -y  install java-1.8.0-openjdk.x86_64 

使用java1.11

#cat centos7/Dockerfile-java1.11
FROM centos7:v1
LABEL maintainer=haogeoyes
RUN echo 'nameserver 10.101.0.1' >> /etc/resolv.conf
RUN yum -y  install java-11-openjdk-demo.x86_64

5、安装jenkins

FROM java:v1
LABEL maintainer=haogeoyes
RUN ping 8.8.8.8 -c 3 && rpm --import https://pkg.jenkins.io/redhat-stable/jenkins.io.key &&  cd /etc/yum.repos.d/  && curl -O https://pkg.jenkins.io/redhat-stable/jenkins.repo && yum -y install jenkins

docker build -t jenkins:v1 -f Dockerfile-jenkins .

报错 使用特权模式 systemctl start jenkins
Failed to get D-Bus connection: Operation not permitted

特权模式启动
docker run -itd --privileged=true jenkins:v1 /usr/sbin/init

下载maven
wget https://dlcdn.apache.org/maven/maven-3/3.8.6/binaries/apache-maven-3.8.6-bin.tar.gz --no-check-certificate && tar zxvf apache-maven-3.8.6-bin.tar.gz && mv apache-maven-3.8.6-bin. /user/local/maven && /user/local/maven/bin/mvn -v

运行
nohup java -jar /tmp/*.jar > /tmp/run.log 2>&1 &

yum -y install git 需要提前安装git 才不会报错 对不公开项目需要用户密码凭证

新增maven
构建项目之后需要做什么 Post Steps

mac maven 配置
https://maven.apache.org/
下载
解压 sudo mv maven
vi .bash_profile
export PATH=$PATH:/usr/local/maven/bin
source .bash_profile
vi /usr/local/maven/conf/settings.xml

配置maven

              jdk-1.8
              
                true
                1.8
              
              
                1.8
                1.8
                1.8
              
         
  

上传镜像
参考

复杂
容器生成镜像
docker commit -m “jenkins安装完成” -a =“haogeoyes” 82e18d339fff haogeoyes/jenkins:v1.1
上传镜像
docker push haogeoyes/jenkins:v1.1

jenkins java 路径
/var/lib/jenkins/workspace/first/target

/usr/local/maven/bin/mvn clean package -Dmaven.test.skip=true
[JENKINS] Archiving /var/lib/jenkins/workspace/first/pom.xml to com.demo/demo-1/0.0.1-SNAPSHOT/demo-1-0.0.1-SNAPSHOT.pom
[JENKINS] Archiving /var/lib/jenkins/workspace/first/target/demo-1-0.0.1-SNAPSHOT.jar to com.demo/demo-1/0.0.1-SNAPSHOT/demo-1-0.0.1-SNAPSHOT.jar

启动命令指定端口
java -jar /var/lib/jenkins/workspace/first/target/demo-1-0.0.1-SNAPSHOT.jar --server.port=8088

启动java服务器

docker run -itd --privileged=true java:v1.11 -p 8005:8080
docker cp  xx.jar xx:/tmp
java -jar demo-1-0.0.1-SNAPSHOT.jar

远程部署 安装publish插件

构建后的操作

添加跳板主机

docker cp 82:/var/lib/jenkins/workspace/first/target/demo-1-0.0.1-SNAPSHOT.jar /tmp && docker run -itd --privileged=true -p 8006:8080 -v /tmp:/tmp java:v1.11 java -jar /tmp/*.jar
将构建好的包 拷贝到本地 挂在启动 java 服务器

构建前的操作

git webhook 钩子回调

6、pipline

pipeline { //整体定义
    agent any //指定机器

    stages { //步骤
        stage('拉取代码') { //每一阶段的名称
            steps {
                echo '拉取成功'
            }
        }
        stage('执行构建') { //每一阶段的名称
            steps {
                echo '构建完成'
            }
        }        
    }
}

7、api 接口

python 接口

pip install jenkinsapi
from jenkinsapi.jenkins import Jenkins
url = "http://14.29.251.27:8004/"
username = "admin"
password = "123456"
jk =Jenkins(url, username, password, useCrumb=True)

>>> jk.keys()    
['first', 'gitTest', 'mypipline']  任务列表
>>> jk.get_job('first').get_last_buildnumber()
14   最近一次构建
构建项目
jk.build_job("first")
>>> jk.get_job('first').is_queued_or_running()
False  是否在构建
>>> jk.get_job('first').get_build(14).get_timestamp()+ datetime.timedelta(hours=8)
datetime.datetime(2022, 10, 7, 7, 3, 8, tzinfo=)  构建信息
>>> jk.get_job('first').get_build(14).get_status()
'UNSTABLE' 状态
>>> jk.get_job('first').get_build(14).get_changeset_items()
