Docker Dockerfile A description of the new mirror on the existing Tomcat image _docker

If you need to replace or add a file to the old Tomcatimage to form a new image, you need to do something in Dockerfile

From Old_tomcat
#这里可以使用docker官方的镜像, the following descriptions are examples of
maintainer ****************** on this basis
#如果需要替换原有的配置文件或者脚本 
ADD web.xml/usr/local/tomcat/webapps/manager/web-inf/ 
Add tomcat-users.xml/usr/local/tomcat/conf/ 
Add server.xml/usr/local/tomcat/conf/ 
add catalina.sh/usr/ local/tomcat/bin/ 
ADD needs to hit the war package name in image. war/usr/local/tomcat/webapps/
expose 8080 
CMD ["/usr/local/ Tomcat/bin/catalina.sh "," Run "]

And then

Docker build-t New_tomcat.

A new modified mirror is formed, and when you start a container for the new mirror, the war is already in the early container, and you do not need to map the host host directory to/usr/local/tomcat/webapps/
