After deploying WAR for Tomcat docker container always getting 404

I have a grails application that is already running and deploying to AWS through Elastic Beanstalk on Tomcat8 Jre8.

Now I'm trying to deploy it in a multi-docker environment, and I have rather strange behavior.

I use tomcat:8.0-jre8( https://hub.docker.com/r/library/tomcat/ ) as the image for the container, and deploying on this image is pretty simple by putting the war file in <tomcat_home>/webapps. In addition, I map the port 8080to the outside world. So, the related part of the docker layout looks like this:

api:
  image: tomcat:8.0-jre8
  container_name: api
  volumes:
    - ./deployment/api:/usr/local/tomcat/webapps
  external_links:
    - mysql:mysql
  ports:
    - "8080:8080"

Based on the logs, the application is being successfully deployed, and even migratory bases migrations are applied:

Enable debug logging for this logger for a complete list of JARs that were scanned but no TLDs were found in them. Skipping unneeded JARs during scanning can improve startup time and JSP compilation time.
