Your iptables do not contain 127.0.0.1 and ::1 as destination?
I would try it without a packet filter first.

Has anyone managed to get undertow working with docker (on CoreOS)?
I have a very basic jar that starts up an undertow server on (localhost at port 80) and has a single HttpHandler at the endpoint ‘/hello’. I’ve tested the jar locally and the endpoint works fine.
I have a docker file along the lines of:
---------------
FROM dockerfile/java:oracle-java8
## wget the app from a server
CMD java -jar my-app.jar
EXPOSE 80
---------------
I then run the container (after building it from the above docker file) as follows:
docker run -d -p 80:80 my-app
(Yes I made sure the server did start and is running before the following:)
I see that the iptables are as follows (which is identical to what dockerfiles/nginx produces):
---------------
Chain INPUT (policy ACCEPT)
target prot opt source destination
Chain FORWARD (policy ACCEPT)
target prot opt source destination
ACCEPT tcp -- anywhere 172.17.0.65 tcp dpt:http
ACCEPT all -- anywhere anywhere ctstate RELATED,ESTABLISHED
ACCEPT all -- anywhere anywhere
ACCEPT all -- anywhere anywhere
Chain OUTPUT (policy ACCEPT)
target prot opt source destination
---------------
Finally I try to curl at the ‘/hello’ endpoint but I just get a connection refused. I try the curl request to localhost from within the same server and it doesn’t work. I also try from a different computer using the public IP of the machine and it does’t work.
The dockerfile/nginx works perfect when I curl at it at port 80.
I’m stumped for ideas, please help!
Thanks,
Chris
