1. 下载jdk

下载tar包,上传到node https://pan.baidu.com/s/18IicPYf7W0j-sHBXvfKyyg

  配置环境变量

export JAVA_HOME=/home/jdk1.8.0_161
export JRE_HOME=${JAVA_HOME}/jre
export CLASSPATH=.:${JAVA_HOME}/lib:${JRE_HOME}/lib
export PATH=.:${JAVA_HOME}/bin:$PATH

2. 下载tomcat,到node的/home目录下
wget https:mirror.bit.edu.cn/apache/tomcat/tomcat-9/v9.0.34/bin/apache-tomcat-9.0.34.tar.gz

3. 下载jenkins 到/home
wget http:mirrors.jenkins-ci.org/war/latest/jenkins.war

将jenkins的war放到tomcat的webaap目录下
mv jenkins.war /home/tomcat9/webapps

启动tomcat

4. 下载git,直接在node执行命令
apt-get install get

5. 下载maven,到/home目录
wget https:mirror.bit.edu.cn/apache/maven/maven-3/3.6.3/binaries/apache-maven-3.6.3-bin.tar.gz

解压,mv maven... maven3

配置环境变量

export M2_HOME=/home/maven3
export CLASSPATH=$CLASSPATH:$M2_HOME/lib
export PATH=$PATH:$M2_HOME/bin

修改maven仓库,maven3/conf/settings.xml

maven Integration plugin

docker pull registry

docker run -p 5000:5000 -v /home/registry_images:/var/lib/registry -d registry

/etc/docker/daemon.json

{
  "insecure-registries":["192.168.1.104:5000"],//修改为registry所在容器的宿主机
  "registry-mirrors": [https://w52p8twk.mirror.aliyuncs.com"]
}

systemctl daemon-reload
systemctl restart docker

领取Nginx镜像
docker pull Nginx
改名
docker tag Nginx 192.168.1.104:5000/Nginx:test

docker push 5000/Nginx:test

{
  insecure-registries":[192.168.1.104:5000],]
}

systemctl daemon-reload
systemctl restart docker

构建的整体流程:
1. 设置参数化构建
2. 设置代码库的地址
3. 设置maven的构建命令,执行后会打包出一个jar包,将jar打包成一个动态镜像,并推到镜像仓库中
4. 将应用部署的yaml文件拷贝到k8s的master节点上,然后执行命令,让k8s根据yaml文件启动应用
