Kubernetes部署Jenkins

1. 构建tomcat镜像
2. 通过Docker镜像部署Jenkins

1. 构建tomcat镜像

//目录结构
[root@master ~]# tree /tomcat/
/tomcat/
├── Dockerfile
└── files
    ├── apache-tomcat-9.0.56.tar.gz
    ├── index.jsp
    ├── install.sh
    ├── jenkins-2.303.1.war
    └── jenkins-2.303.2.war

1 directory, 6 files

//编写dockerfile文件
[root@master ~]# cat /tomcat/Dockerfile 
FROM centos

LABEL MAINTAINER "harry1004 1@2.com"

ENV version 9.0.56
ENV jenkins_vsn 2.303.1
ENV PATH $PATH:/usr/local/tomcat/bin

ADD files/apache-tomcat-${version}.tar.gz /usr/local/

COPY files/jenkins-${jenkins_vsn}.war /usr/local/
COPY files/index.jsp /usr/local/
COPY files/install.sh /tmp/

RUN /tmp/install.sh

EXPOSE 8080

WORKDIR /usr/local/tomcat/bin

CMD ["/usr/local/tomcat/bin/catalina.sh","run"]

//编写脚本配置文件
[root@master ~]# cat /tomcat/files/install.sh 
#!/bin/bash

rm -rf /etc/yum.repos.d/*
curl -o /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-$(awk -F'"' 'NR==5{print $2}'  /etc/os-release).repo 
sed -i -e '/mirrors.cloud.aliyuncs.com/d' -e '/mirrors.aliyuncs.com/d' /etc/yum.repos.d/CentOS-Base.repo 
yum -y install java-1.8.0-openjdk 
ln -s /usr/local/apache-tomcat-${version}/ /usr/local/tomcat
cd /usr/local/
mkdir /usr/local/tomcat/webapps/test
cp index.jsp /usr/local/tomcat/webapps/test/
[root@master tomcat]# chmod u+x files/install.sh

//编写测试页面文件
[root@master ~]# cat /tomcat/files/index.jsp 
<html>
<head>
         <title>test page</title>
</head>
<body>
         <%
           out.println("Hello World");
         %>
</body>
</html>

//生成镜像
[root@master tomcat]# docker build -t harry1004/tomcat:v1.0 /tomcat/
......略
Successfully built 69eb5a3b1e8f
Successfully tagged harry1004/tomcat:v1.0

[root@master tomcat]# docker run -itd --name tomcat -p 8080:8080 harry1004/tomcat:v1.0

在这里插入图片描述

2. 通过Docker镜像部署Jenkins

# 交互模式登录tomcat容器
[root@master tomcat]# docker run -itd --name tomcat -p 8080:8080 harry1004/tomcat:v1.0
db3d4a09a1f9ed0bf412fe7eb28e77370ec8b55ee11ddf33cb8dfeda964b1ab0
[root@master tomcat]# docker exec -it tomcat /bin/bash
[root@db3d4a09a1f9 bin]# cd ../webapps/ROOT/

# 复制jenkins包当当前目录下
