06--Docker自定义镜像Tomcat9

1. 创建目录 /zhengcj/mydockerfile/tomcat9

2.将jdk和tomcat的安装包拷贝到tomcat9下

3.在tomcat9目录下创建Dockerfile文件，并写以下命令

FROM         centos
MAINTAINER    zhengcj<zhnen@qq.com>
#把宿主机当前上下文的c.txt拷贝到容器/usr/local/路径下
COPY c.txt /usr/local/cincontainer.txt
#把java与tomcat添加到容器中
ADD jdk-8u231-linux-x64.tar.gz /usr/local/
ADD apache-tomcat-9.0.41.tar.gz /usr/local/
#安装vim编辑器
RUN yum -y install vim
#设置工作访问时候的WORKDIR路径，登录落脚点
ENV MYPATH /usr/local
WORKDIR $MYPATH
#配置java与tomcat环境变量
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-9.0.41
ENV CATALINA_BASE /usr/local/apache-tomcat-9.0.41
ENV PATH $PATH:$JAVA_HOME/bin:$CATALINA_HOME/lib:$CATALINA_HOME/bin
#容器运行时监听的端口
EXPOSE  8080
#启动时运行tomcat
# ENTRYPOINT ["/usr/local/apache-tomcat-9.0.41/bin/startup.sh" ]
# CMD ["/usr/local/apache-tomcat-9.0.41/bin/catalina.sh","run"]
CMD /usr/local/apache-tomcat-9.0.41/bin/startup.sh && tail -F /usr/local/apache-tomcat-9.0.41/bin/logs/catalina.out

　　4.构建镜像 docker build -t zhengcj/tomcat9 .

5.查看镜像

6.运行镜像,并创建数据持久化

docker run -d -p 8080:8080 --name myt9 -v /zhengcj/mydockerfile/tomcat9/test:/usr/local/apache-tomcat-9.0.8/webapps/test -v /zhengcj/mydockerfile/tomcat9/tomcat9logs/:/usr/local/apache-tomcat-9.0.8/logs --privileged=true zhengcj/tomcat9

7. 在目录/zhengcj/mydockerfile/tomcat9/test下创建test.html

<?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"
        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">            
            <display-name>test</display-name>         
    </web-app>

8.在目录/zhengcj/mydockerfile/tomcat9/test/WEB-INF下创建web.xml

<html>
	<head>
		<title>根目录</title>
	</head>
	<body>
			测试页面
	</body>
</html>

9. 重启tomcat ：docker restart 容器id
