Problem copying file



I have the following snippet in my docker file:

 ADD app.war /opt/apache-tomcat-8.5.14/webapps/app.war

However, entering the docker image as:

docker exec -it tomcat /bin/sh

and doing an ls to the webapps folder, the file isn’t there. The file, in my local OS, windows, it is in the same folder as the dockerfile. Any clue about why this happens?

However, using the cp command in my windows cmd, it works correctly after checking in the container.
