### 1. 安装JDK ###

安装目录：/home/docker/download/jdk\_install  
在此目录下面制作Dockerfile 和 JDK(解压包)。  
**a. Dockerfile**

FROM busybox
    MAINTAINER Brant shi "153551367@qq.com"
    LABEL Description="jdk volume" Vendor="Brant" Version="1.8"
    VOLUME "/opt/jdk"
    ADD . /opt

**b. JDK**  
下载jdk压缩包， 并解压放在JDK的目录下面；  
  
**c. build**  
docker build .  
  
**d. 运行jdk**  
docker run --detach -it --name jdk1.8 jdk1.8

### 2. 安装jenkins ###

安装目录：/home/docker/download/jenkins\_install  
在此目录下面制作Dockerfile 和 jenkins(解压包)  
**a. Dockerfile**

FROM busybox
    MAINTAINER Brant shi "153551367@qq.com"
    LABEL Description="jenkins war" Vendor="Brant" Version="latest"
    VOLUME ["/opt/tomcat/webapps/jenkins"]
    RUN mkdir -p /opt/tomcat/webapps
    ADD . /opt/tomcat/webapps

**b. jenkins**  
下载jenkins.war， 并解压放在jenkins的目录下面；  
  
**c. build**  
docker build .  
  
**d. 运行jenkins-war**  
docker run --detach -it --name jenkins-war jenkins-war

### 3. 安装tomcat8  ###

安装目录：/home/docker/download/tomcat\_install  
在此目录下面制作Dockerfile 和 tomcat(解压包)  
**a. Dockerfile**

FROM centos
    MAINTAINER Brant shi "153551367@qq.com"
    LABEL Description="Apache tomcat" Vendor="Brant" Version="8"
    ADD . /opt
    
    # Define ENV
    ENV LANG C.UTF-8
    ENV CATALINA_HOME /opt/tomcat
    ENV PATH $PATH:$CATALINA_HOME/bin
    
    # Exporse ports
    EXPOSE 8080 
    
    # Volume
    VOLUME ["$CATALINA_HOME/conf","$CATALINA_HOME/logs","$CATALINA_HOME/webapps","$CATALINA_HOME/work"]
    
    # Define entrypoint
    ENTRYPOINT ["catalina.sh", "run"]

**b. tomcat**  
下载tomcat.gz， 并解压放在tomcat的目录下面；  
  
**c. build**  
docker build .

### 4. 部署jenkins ###

**a. 制作启动文件 jenkins.sh**

\#使用本地资源的启动脚本

#!/bin/bash
    echo "restart jenkins..."
    docker stop jenkins && echo "停止服务成功！" || echo "停止服务失败！"
    docker rm jenkins && echo "销毁服务成功！" || echo "销毁服务失败！"
    docker run -tid --restart=always \
        --env JAVA_HOME=/usr/local/jdk \
        --env JAVA_OPTS="-Xms1536m -Xmx1536m -XX:MaxPermSize=512m" \
        --env MAVEN_HOME=/usr/local/maven \
        --publish 5010:8080 \
        --memory-swappiness=1 \
        --ulimit nofile=20480:40960 \
        --volume /home/docker/sofeware/maven:/usr/local/maven:rw \
        --volume /home/docker/sofeware/.m2:/root/.m2:rw \
        --volume /home/docker/sofeware/jdk:/usr/local/jdk \
        --volumes-from jenkins-war \
        --volume /usr/bin/git:/usr/bin/git:ro \
        --volume /usr/libexec/git-core:/usr/libexec/git-core:ro \
        --volume /home/docker/jenkins/jenkins_home:/root/.jenkins:rw \
        --volume /home/docker/jenkins/conf:/opt/tomcat/conf \
        --volume /home/docker/jenkins/logs:/opt/tomcat/logs \
        --volume /etc/hosts:/etc/hosts:ro \
        --name jenkins \
        tomcat8

**b.运行jenkins （这里设置运行权限什么的都不说了）**  
./jenkins.sh   
  
**c. 开发端口5010 **  
firewall-cmd --zone=public --add-port=5010/tcp --permanent firewall-cmd --reload

### 5. 用nginx代理（域名：jenkins.weipaiku.com） ###

**a. 设置虚拟目录文件**

server {
      listen 80;
      server_name jenkins.weipaiku.com;
    
      client_max_body_size 0;
      chunked_transfer_encoding on;
    
      location / {
      	index /jenkins;
      }
    
      location /jenkins {
        proxy_pass                          http://192.168.0.210:5010/jenkins;
        proxy_set_header  Host              $http_host;   # required for docker client's sake
        proxy_set_header  X-Real-IP         $remote_addr; # pass on real client's IP
        proxy_set_header  X-Forwarded-For   $proxy_add_x_forwarded_for;
        proxy_set_header  X-Forwarded-Proto $scheme;
        proxy_read_timeout                  900;
      }
    }

**b. 重启nginx**  
docker restart nginx

### 6. 访问jenkins ###

http://jenkins.yaok.com/  
  
进入docker 容器中，获取初始化密码：

$ docker exec -it jenkins bash
    $ cat /root/.jenkins/secrets/initialAdminPassword

到此已经完成部署了。
