I have created Docker container and Tomcat is running in this container. How can I deploy a webapp or war file in Tomcat that is running in docker container.

First create a Dockerfile:

FROM library/tomcat
RUN rm -rf /usr/local/tomcat/webapps/*
ADD ./relative/path_to_war.war /usr/local/tomcat/webapps/ROOT.war

Then build Docker image

$ docker build -t user/image_name .

And finally run docker container. 

$ docker run --name container_name -p 80:8080 -d user/image_name

After that your webapp should be responding on Docker host's ip on default http 80 port.

You might need to link a database container to your webapp, see more on Docker documentation

You can implement an effective way of using Tomcat Docker.

docker run -d -p 80:8080 -v <mount-path>:/usr/local/tomcat/webapps/ tomcat:8.0

And then copy the .war files to the mounted volume. This would eliminate the need for restarting the Tomcat Docker each time when there is a code change. A zero downtime implementation could be achieved.

If it's a one-time deployment then you may create a custom Docker and copy the war file into /usr/local/tomcat/webapps/ and start the Docker.
