What is the docker way to deploy java projects in a docker container?

Do I copy the war into webapps:

If you stumbled here, like I did, looking for how to simply get a WAR deployed in a container (using Apache Tomcat), and didn't care whether or not you have a Dockerfile.

A simple, elegant solution.

docker run \
-d \ # Detached mode, swap for -it if we want interactive.
-p 8080:8080  \
-v ${absolute_path_your_project_dir}/${MY_WAR}.war:/usr/local/tomcat/webapps/app.war \
tomcat:latest

Then navigate to http://localhost:8080/app/.

If that link doesn't work for you, be sure to change ...8080/app/ in the URL to whatever matches the .war name you gave in /usr/local/tomcat/webapps/app.war.

I also found that, while working through IntelliJ's Docker Plugin, it's easy to adapt this to Docker Plugins. Just be sure to put in your full path.
