Hello!
I have been attempting to run a persistent Tomcat webserver/webapp inside of a Docker container generated by Aurora, all inside Vagrant. The docker image is preloaded with the Tomcat software and webapp, such that it only requires a run command in order to start the Tomcat webapp. I wanted to be able to see my webapp in browser so I attempted to publish the Docker port onto a port on the Vagrant environment, using the following code as part of the Service description in the .aurora: container = Docker(image = 'tomcatimage', parameters = [Parameter(name = 'publish', value = '8080:8080')]) The docker image executes the Dockerfile command "EXPOSE 8080", which I can safely assume accomplishes what it promises. The publish parameter is used to map the 8080 port inside docker to the host port 8080. So, the webapp should be visible at http:\\localhost:8080 , where localhost is designated by the Vagrantfile. However, this does not successfully publish onto the 8080 host port. When I run the docker container independently of Aurora, without any input parameters, and type 'docker ps' into the CLI, the output shows "8080/tcp" under "PORTS". If I run the container with the flag "-p 8080:8080", the 'docker ps' output shows "0.0.0.0:8080->8080/tcp": this mapping results in a webpage I can access by navigating a browser to http://192.168.33.7:8080 , with 192.168.33.7<http://192.168.33.7:8080> being the localhost defined in the Vagrantfile. However, when aurora generates the docker container (using the same docker image), it has nothing at all listed in the "PORTS" output of 'docker ps', and cannot be accessed by navigating to a web page. Has anyone experienced this (fairly specific) problem? Suggestions? Any additional details required to diagnose? Thanks!
