The project in docker commit’s new jetty mirror webapps cannot run.

  docker, question

1. Use the mirror image of docker jetty to make a web application
2. Modify this container and use commit commit to generate a new image
3. Items in webapps cannot be started when running the container based on the new image, but jetty itself is started

#Dockerfile
 FROM test:jetty
 
 COPY a /var/lib/jetty/webapps
 
 CMD ["java","-jar","/usr/local/jetty/start.jar"]

Jetty version is hub.c.163.com/library/jetty:9.2

This can be done using Dockerfile.

FROM test:jetty
 # Delete an existing item
 RUN rm -rf /var/lib/jetty/webapps/test
 # copy everything in directory a to the container's webapps directory
 COPY a /var/lib/jetty/webapps
