Create a Dockerfile like this:
FROM dockerfile/java# Install TomcatRUN sudo apt-get update && sudo apt-get install tomcat7# Add your webapp file into your docker image into Tomcat's webapps directory# Your webapp file must be at the same location as your DockerfileADD mywebapp.war /var/lib/tomcat7/webapps/# Expose TCP port 8080EXPOSE 8080# Start Tomcat server# The last line (the CMD command) is used to make a fake always-running# command (the tail command); thus, the Docker container will keep running.CMD sudo service tomcat7 start && tail -f /var/log/tomcat7/catalina.outBuild the image:
$ docker build -t tomcat7-test <Dockerfile's path>And then, run it:
$ docker run -d -p 8080:8080 tomcat7-test
