How to contact nova-docker instance from outside world

Hi,

I am running nova-docker and I have an application which uses port 8080. Within the same host I can ping docker instance, ssh or send POST request to the running application in docker. However from outside the host everything is impossible.

I know for docker there is this port binding between docker and host, but is the same thing possible for nova-docker? How can I contact from another machine the docker instance running in openstack?

Same way goes AIO install on bare metal for RDO Kilo on CentOS 7.1.
When installing on RDO Kilo Compute node (bare metal) , all Glance changes should be done on Controller. Then you are supposed define security groups rules for tenant running nova-docker instances.
Inbound (via floating IPs) and outbound connectivity runs fine for Nova-Docker instances RDO Kilo installed on CentOS 7.1 Compute node
Regarding Ubuntu, view http://bderzhavets.blogspot.com/2015/...

Thanks for the answer. I am using ubuntu and devstack with nova-docker plugin. The link that you posted just shows how to install RDO kilo on CentOS. I added security rules using nova secgroup-add-rule but still no luck.
