自定义tomcat业务镜像

　　　　　　　　　　　　　　自定义tomcat业务镜像

　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　作者：尹正杰

　　本实验是在上一篇笔记制作的tomcat基础镜像(https://www.cnblogs.com/yinzhengjie/p/12227825.html)之上制作的tomcat业务相关代码。

一.准备测试数据

1>.编写Dockerfile文件

[root@docker101.yinzhengjie.org.cn ~]# cat /yinzhengjie/softwares/dockerfile/web/tomcat/tomcat-app01/Dockerfile

#基于咱们自己定义的tomcat基础镜像部署tomcat代码
FROM tomcat-base:8.5.50

#指定镜像维护者的信息.
MAINTAINER Jason.Yin y1053419035@qq.com

#将tomcat代码不要放在tomcat的启动目录,这样会导致tomcat启动相当慢,生产环境中建议大家将tomcat应用程序和代码分开存放
ADD code.tar.gz /yinzhengjie/data/tomcat/webapps/app01

#切记要修改目录权限哈,因为安装服务是用root用户安装的而启动用户则是使用tomcat用户
RUN chown -R tomcat:tomcat /yinzhengjie/data/tomcat /yinzhengjie/softwares/web/apache-tomcat-8.5.50

#将tomcat的配置文件替换基础镜像的配置文件
COPY server.xml /yinzhengjie/softwares/web/tomcat/conf

#将tomcat的启动脚本添加到tomcat安装路径中
COPY run_tomcat.sh /yinzhengjie/softwares/web/tomcat/bin/run_tomcat.sh

#指定暴漏端口,其实这一步步骤不写也是ok的
EXPOSE 8080 8443

#指定启动tomcat的启动脚本
CMD ["/yinzhengjie/softwares/web/tomcat/bin/run_tomcat.sh"]
[root@docker101.yinzhengjie.org.cn ~]# 
[root@docker101.yinzhengjie.org.cn ~]#

2>.编写编译脚本

[root@docker101.yinzhengjie.org.cn ~]# cat /yinzhengjie/softwares/dockerfile/web/tomcat/tomcat-app01/build-command.sh 
#!/bin/bash
#

docker image build -t tomcat-app01:v0.1 .

3>.编写tomcat的配置文件

[root@docker101.yinzhengjie.org.cn ~]# cat /yinzhengjie/softwares/dockerfile/web/tomcat/tomcat-app01/server.xml
