Docker学习(19)——利用DockerFile制作tomcat镜像

（1）压缩包

apache-tomcat-9.0.22.tar.gz 下载地址：https://archive.apache.org/dist/tomcat/tomcat-9/v9.0.22/bin/

jdk-8u60-linux-x64.tar.gz

（2）编写Dockerfile

Dockerfile

FROM centos
MAINTAINER dong<7712199@qq.com>

COPY readme.txt /usr/local/readme.txt

ADD jdk-8u60-linux-x64.tar.gz /usr/local/
ADD apache-tomcat-9.0.22.tar.gz /usr/local/

RUN yum -y install vim

ENV MYPATH /usr/local
WORKDIR $MYPATH

ENV JAVA_HOME /usr/local/jdk1.8.0_60
ENV CLASSPATH $JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
ENV CATALINA_HOME /usr/local/apache-tomcat-9.0.22
ENV CATALINA_BASH /usr/local/apache-tomcat-9.0.22
ENV PATH $PATH:$JAVA_HOME/bin:$CATALINA_HOME/lib:$CATALINA_HOME/bin

EXPOSE 8080

CMD /usr/local/apache-tomcat-9.0.22/bin/startup.sh && tail -F /usr/local/apache-tomcat-9.0.22/bin/logs/catalina.out

（3）构建镜像

[root@192 tomcat]# docker build -t dong_tomcat .

执行成功如下图所示：

Successfully built 0b71a90fed81
Successfully tagged dong_tomcat:latest
[root@192 tomcat]# docker images
REPOSITORY            TAG       IMAGE ID       CREATED          SIZE
dong_tomcat           latest    0b71a90fed81   31 seconds ago   684MB
[root@192 tomcat]# 

（4）启动镜像

[root@192 tomcat]# docker run -d -p 9090:8080 --name dongdongtomcat -v /home/docker/tomcat/test:/usr/local/apache-tomcat-9.0.22/webapps/test -v /home/docker/tomcat/tomcatlogs:/usr/local/apache-tomcat-9.0.22/logs dong_tomcat
42e22c4adc09713a71edbddd4c20a28f8f6894779330346aabe00b16cb80c851
[root@192 tomcat]# 

（5）进入容器

[root@192 tomcat]# docker exec -it 42e22c4adc09713a71e /bin/bash
[root@42e22c4adc09 local]# ls
apache-tomcat-9.0.22  bin  etc	games  include	jdk1.8.0_60  lib  lib64  libexec  readme.txt  sbin  share  src
[root@42e22c4adc09 local]# pwd           -------------注释:默认路径为/usr/local
/usr/local
[root@42e22c4adc09 local]# cd apache-tomcat-9.0.22/
[root@42e22c4adc09 apache-tomcat-9.0.22]# ls
BUILDING.txt  CONTRIBUTING.md  LICENSE	NOTICE	README.md  RELEASE-NOTES  RUNNING.txt  bin  conf  lib  logs  temp  webapps  work
[root@42e22c4adc09 apache-tomcat-9.0.22]# 

（6）本地测试

[root@192 tomcat]# curl localhost:9090



         -------------------注释:成功访问

    
        
        
        
        
        
    
...

（7）外网测试

 （8）创建web.xml和index.jsp

web.xml

[root@192 test]# ls
index.jsp  WEB-INF
[root@192 test]# cd WEB-INF/
[root@192 WEB-INF]# ls
web.xml
[root@192 WEB-INF]# pwd
/home/docker/tomcat/test/WEB-INF
[root@192 WEB-INF]# cat web.xml 



[root@192 WEB-INF]# 

index.jsp

[root@192 test]# ls
index.jsp  WEB-INF
[root@192 test]# pwd
/home/docker/tomcat/test
[root@192 test]# cat index.jsp 
<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>







文件上传实例

    选择一个文件:
    
    


    



[root@192 test]# 

（9）外网测试

http://192.168.0.105:9090/test/

 测试成功。

（10）查看日志

[root@192 tomcat]# ls
apache-tomcat-9.0.22.tar.gz  Dockerfile  jdk-8u60-linux-x64.tar.gz  readme.txt  test  tomcatlogs
[root@192 tomcat]# cd tomcatlogs/
[root@192 tomcatlogs]# ls
catalina.2021-10-11.log  host-manager.2021-10-11.log  localhost_access_log.2021-10-11.txt
catalina.out             localhost.2021-10-11.log     manager.2021-10-11.log
[root@192 tomcatlogs]# cat catalina.out
...
