COPY c.txt /usr/local/cincontainer.txt
#把java与tomcat添加到容器中
ADD jdk-8u152-linux-x64.tar.gz /usr/local/
ADD apache-tomcat-8.5.24.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_152
ENV CLASSPATH $JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
ENV CATALINA_HOME /usr/local/apache-tomcat-8.5.24
ENV CATALINA_BASE /usr/local/apache-tomcat-8.5.24
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-8.5.24/bin/startup.sh" ]
# CMD ["/usr/local/apache-tomcat-8.5.24/bin/catalina.sh","run"]
CMD /usr/local/apache-tomcat-8.5.24/bin/startup.sh && tail -F /usr/local/apache-tomcat-8.5.24/bin/logs/catalina.out

5、构建

1

docker build -f Dockerfile -t heiantomcat9 .

构建完成

6、run

1

docker run -d -p 9080:8080 --name myt9 -v /heian/mydockerfile/tomcat9/test:/usr/local/apache-tomcat-9.0.8/webapps/test -v /heian/mydockerfile/tomcat9/tomcat9logs/:/usr/local/apache-tomcat-9.0.8/logs --privileged=true heiantomcat9

Docker挂载主机目录Docker访问出现cannot open directory .: Permission denied
解决办法：在挂载目录后多加一个–privileged=true参数即可

7、验证

8、结合前述的容器卷将测试的web服务test发布
