Copying a war file from my local system to a container directory on katacoda

I am running a tomcat container on katacoda. I want to copy my application’s war file into the webapps directory of the container. The war file is present in my local machine. How do I copy a file from my local machine to a container on katacoda.

through docker copy command.

Thank you for your reply… the docker cp command is not helping as the file I want to copy is present in my local machine, how can I access the file from katacoda. On running the docker cp (path of war file on my laptop) (container name):/usr/local/tomcat/webapps
command on katacoda the following error shows up :
copying between containers is not supported
