1、筹备创立好本人的目录

[root@paperchen paperchen]# pwd/home/paperchen[root@paperchen paperchen]# mkdir -p build/tomcat[root@paperchen tomcat]# pwd/home/paperchen/build/tomcat

2、在上述pwd的目录，即tomcat目录中创立文件等

touch readme.txt

vim Dockerfile

# vim DockerfileFROM centosMAINTAINER paperchen<609120776@qq.com># 把宿主机以后上下文的readme.txt拷贝到容器/usr/local/门路下COPY readme.txt /usr/local/cincontainer.txt# 把java和tomcat增加到容器中（会主动解压）ADD jdk-8u201-linux-x64.tar.gz /usr/local/ADD apache-tomcat-9.0.24.tar.gz /usr/local/# 装置vim编辑器RUN yum -y install vim# 设置启动拜访的初始地位，即工作目录，登录落脚点ENV MYPATH /usr/localWORKDIR $MYPATH# 配置java和tomcat的环境变量ENV JAVA_HOME /usr/local/jdk1.8.0_201ENV CLASSPATH $JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jarENV CATALINE_HOME /usr/local/apache-tomcat-9.0.24ENV CATALINE_BASE /usr/local/apache-tomcat-9.0.24ENV PATH $PATH:$JAVA_HOME/bin:$CATALINE_HOME/lib:$CATALINE_HOME/binEXPOSE 8080# 容器启动后要执行的命令CMD /usr/local/apache-tomcat-9.0.24/bin/startup.sh && tail -F /usr/local/apache-tomcat-9.0.24/bin/logs/catalina.out

3、以后tomcat目录下的所有文件内容

[root@paperchen tomcat]# ls -lltotal 197996-rw-r--r-- 1 root root  10914435 Oct  6 08:46 apache-tomcat-9.0.24.tar.gz-rw-r--r-- 1 root root       646 Oct  6 09:20 Dockerfile-rw-r--r-- 1 root root 191817140 Oct  6 09:06 jdk-8u201-linux-x64.tar.gz-rw-r--r-- 1 root root         0 Oct  6 08:44 readme.txt

4、在tomcat下构建镜像、查看镜像

当dockerfile文件间接命名为Dockerfile，且在同一目录下时能够省略-f dockerfile文件门路

[root@paperchen tomcat]# docker build -t paperchen/diytomcat......Successfully built b64cda437ad2Successfully tagged paperchen/diytomcat:latest

查看构建后的镜像，确认构建胜利

[root@paperchen tomcat]# docker imagesREPOSITORY            TAG                 IMAGE ID            CREATED             SIZEpaperchen/diytomcat   latest              b64cda437ad2        37 minutes ago      684MB

5、运行启动构建的镜像

[root@paperchen tomcat]# docker run -d --privileged=true -p 9090:8080 --name mydiytomcat -v /home/paperchen/build/tomcat/test:/usr/local/apache-tomcat-9.0.24/webapps/test -v /home/paperchen/build/tomcat/tomcat9logs/:/usr/local/apache-tomcat-9.0.24/logs paperchen/diytomcat

测试拜访：

curl localhost:9090或间接外网拜访如：IP:9090

6、联合数据卷内容在内部间接公布测试利用test

[root@paperchen test]# pwd/home/paperchen/build/tomcat/test[root@paperchen test]# mkdir WEB-INF[root@paperchen test]# cd WEB-INF/[root@paperchen WEB-INF]# vim web.xml[root@paperchen WEB-INF]# cd ..[root@paperchen test]# vim index.jsp

web.xml

<?xml version="1.0" encoding="UTF-8"?><web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"         xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee                      http://xmlns.jcp.org/xml/ns/javaee/web-app_4_0.xsd"         version="4.0"         metadata-complete="true"></web-app>

index.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8" %><!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"><html><head>    <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">    <title>hello，paperchen</title></head><body>-----------welcome------------<br>" my docker tomcat，paperchen "<br><%    System.out.println("-------my docker tomcat-------");%></body></html>

测试拜访：

curl localhost:9090/test/index.jsp或间接外网拜访如：IP:9090/test/index.jsp

胜利！

7、查看日志信息

[root@paperchen tomcat]# cd tomcat9logs/[root@paperchen tomcat9logs]# ls -lltotal 24-rw-r----- 1 root root 6995 Oct  6 09:30 catalina.2020-10-06.log-rw-r----- 1 root root 7057 Oct  6 09:37 catalina.out-rw-r----- 1 root root    0 Oct  6 09:26 host-manager.2020-10-06.log-rw-r----- 1 root root  406 Oct  6 09:26 localhost.2020-10-06.log-rw-r----- 1 root root  245 Oct  6 09:37 localhost_access_log.2020-10-06.txt-rw-r----- 1 root root    0 Oct  6 09:26 manager.2020-10-06.log[root@paperchen tomcat9logs]# cat catalina.out......-------my docker tomcat--------------my docker tomcat-------
