docker：（2）通过Dockerfile构建镜像并发布web项目
上一篇讲解了docker的基本使用 http://www.cnblogs.com/xiaochangwei/p/8204511.html
虽然通过修改获取到的镜像可以达到使用目的，但是多操作几次就会发现，操作还是比较繁琐，扩充也不是很方便
而取而代之的方法就是通过Dockerfile来构建自己想要的镜像，
在linux下编译过C程序的同学肯定知道Makefile, Dockerfile和其一样，就是为了达到快速编译（生成）想要的镜像的
下面以j2ee最常用的场景：在ubuntu下配置jdk环境，并用tomcat发布一个war包的web项目
1.准备好需要的jdk 和 tomcat
xiaochangwei@ubuntu:~/test$ date Thu Jan 4 23:00:38 PST 2018 xiaochangwei@ubuntu:~/test$ ls -l total 14180 -rw-rw-r-- 1 xiaochangwei xiaochangwei 14501238 Dec 19 23:29 demo.war -rw-rw-r-- 1 xiaochangwei xiaochangwei 551 Jan 4 18:18 Dockerfile drwxr-xr-x 8 xiaochangwei xiaochangwei 4096 Dec 12 2016 jdk drwxrwxr-x 6 xiaochangwei xiaochangwei 4096 Dec 20 21:51 maven drwxrwxr-x 9 xiaochangwei xiaochangwei 4096 Dec 20 18:28 tomcat xiaochangwei@ubuntu:~/test$
这里我将jdk和tomcat的tar.gz 包都通过 tar -zxvf解压了 并通过mv 修改了文件夹名字为jdk和tomcat
（其实不解压也可以，2中说明为啥我要解压，为啥不用解压而我又先解压了）
2.编写Dockerfile（示例如下）
1 FROM ubuntu:16.04 2 MAINTAINER changw.xiao@qq.com 3 COPY ./jdk /usr/local/jdk 4 COPY ./tomcat /tomcat 5 COPY ./maven /usr/local/maven 6 7 ENV M2_HOME=/usr/local/maven 8 ENV JAVA_HOME /usr/local/jdk 9 ENV JRE_HOME $JAVA_HOME/jre 10 ENV CLASSPATH .:$JAVA_HOME/lib:$JRE_HOME/lib 11 ENV PATH $PATH:$JAVA_HOME/bin 12 ENV PATH $PATH:$M2_HOME/bin 13 ENV CATALINA_OPTS -Xms128m -Xmx1024m -XX:PermSize=64M -XX:MaxPermSize=512M 14 RUN cd /tomcat/logs && echo "1" >>count.txt 15 ENTRYPOINT /tomcat/bin/startup.sh && tail -F /tomcat/logs/catalina.out
根据显示的行号来解释
1.我们制作镜像的基础，在ubuntu16.04的系统上构建后续操作
2.维护者信息
3~5.复制当前目录下的jdk目录 到容器内部的/usr/local/jdk目录下
解释下：
Dockerfile提供了COPY 和 ADD 两种方式
COPY : COPY ./jdk /usr/local/jdk #直接原样拷贝过去
ADD : ADD ./jdk-8u121-linux-x64.tar.gz /usr/local/java #拷贝过去，如果是压缩包还会自动帮着解压，本来是好事，但是解压后文件夹名字一长串，不便于记忆，就直接先解压好重命名好了再COPY过去
7~13.一看就知道了 通过 ENV 来设置各种环境变量
14.为了示例RUN的使用， 通过RUN命令，后面就可以执行各种linux命令
15.表示启动容器后执行的操作
将上述文件保存为Dockerfile 注意大小写，没有后缀，然后进入到该目录，执行命令构建镜像
sudo docker build -t xiaochangwei/tomcat:v1 --rm=true .
#如果改变了Dockerfile名字，则需要指定 -f 文件名称
xiaochangwei/tomcat:v1 镜像的名字及tag， 最后的点代表当前目录

至此，我们需要的tomcat镜像就已经制作完成了
也发布到docker cloud上去吧
上传时间根据网络和镜像大小来决定，网络差的同学多等待下

docker cloud上也有了，不过提醒下，这里要稍微多等下，有时候命令行显示上传完了，但是网页端还是没有，不用急，多等会儿
启动试试看
sudo docker run -p 8899:8080 --name tomcat_xiao xiaochangwei/tomcat:v1
如果想后台运行 可以在run后加 -d 参数即：sudo docker run -d -p 8899:8080 --name tomcat_xiao xiaochangwei/tomcat:v1 其余参数不解释，看上一篇文章

看见猫了就表示对了
然后问题又来了，容器倒是启动起来了，但是怎么把我们自己的war包丢里面运行起来呢？
sudo docker cp demo.war tomcat_xiao:/usr/local/tomcat/webapps
demo.war 不解释
tomcat_xiao:/usr/local/tomcat/webapps 冒号前面为容器名称或者id， 冒号后面为tomcat的webapps全路径
丢进去就好了，会自动发布的，不需要我们再自己去启动tomcat了，因为容器启动后tomcat就默认启动了 Dockerfile最后一行就是启动tomcat
丢进去后，控制台就会检测到，并自动部署

与jenkins整合，实现持续集成
还有暂时没想到的东西
