#### 实战: Tomcat镜像 ####

1、首先准备镜像tomcat压缩包、jdk压缩包

2、编写dockerfile文件，官方命名 Dockerfile，build 的时候自动寻找这个文件，就不需要-f指定了

FROM centos
    MAINTAINER liulihui<llhui20@sina.com>
    
    COPY readme.txt /usr/local/readme.txt
    
    ADD jdk-8u231-linux-x64.tar.gz /usr/local/
    ADD apache-tomcat-8.5.50.tar.gz /usr/local/
    
    ENV MYPATH /usr/local
    WORKDIR $MYPATH
    
    ENV JAVA_HOME /usr/local/jdk1.8.0_231
    ENV CLASSPATH $JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
    
    ENV CATALINA_HOME /usr/local/apache-tomcat-8.5.50
    ENV CATALINA_BASH /usr/local/apache-tomcat-8.5.50
    ENV PATH $PATH:$JAVA_HOME/bin:$CATALINA_HOME/lib:$CATALINA_HOME/bin
    
    EXPOSE 8080
    CMD /usr/local/apache-tomcat-8.5.50/bin/startup.sh && tail -f /usr/local/apache-tomcat-8.5.50/logs/catalina.out

3、构建镜像

[root@liulihui tomcat]# docker build -t diytomcat .

4、启动镜像

# 查看镜像 
    [root@liulihui tomcat]# docker images
    REPOSITORY            TAG       IMAGE ID       CREATED          SIZE
    diytomcat             latest    151a2aa6587a   22 seconds ago   649MB
    
    # 启动镜像 diytomcat
    [root@liulihui tomcat]# docker run -d -p 9090:8080 --name liulihuitomcat -v /home/liulihui/build/tomcat/test:/usr/local/apache-tomcat-8.5.50/webapps/test -v /home/liulihui/build/tomcat/tomcatlogs/:/usr/local/apache-tomcat-8.5.50/logs diytomcat

5、访问测试

6、发布镜像 (由于做了挂载，直接在本地编写项目就可以发布了！) ，编写web.xml文件

<?xml version="1.0" encoding="UTF-8"?>
    <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xmlns="http://java.sun.com/xml/ns/javaee"
        xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
        xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
        id="WebApp_ID" version="2.5">
        
        
    </web-app>

![在这里插入图片描述][f219e826791648abbdac39c233e0bfbd.png]  
测试 编写 index.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8"
        pageEncoding="UTF-8"%>
    <!DOCTYPE html>
    <html>
    <head>
    <meta charset="utf-8">
    <title>hello liulihui</title>
    </head>
    <body>
    Hello World!<br/>
    <%
    System.out.println("----- my test web logs--------");
    %>
    </body>
    </html>

访问：http://ip:9090/test/

发现部署成了，可以直接访问ok！
