<br>
Has anyone managed to get undertow working with docker (on CoreOS)?<br>
<br>
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.<br>
<br>
I have a docker file along the lines of:<br>
<br>
---------------<br>
FROM dockerfile/java:oracle-java8<br>
<br>
## wget the app from a server<br>
<br>
CMD java -jar my-app.jar<br>
<br>
EXPOSE 80<br>
---------------<br>
<br>
I then run the container (after building it from the above docker file) as follows:<br>
<br>
docker run -d -p 80:80 my-app<br>
<br>
(Yes I made sure the server did start and is running before the following:)<br>
<br>
I see that the iptables are as follows (which is identical to what dockerfiles/nginx produces):<br>
<br>
---------------<br>
Chain INPUT (policy ACCEPT)<br>
target prot opt source destination<br>
<br>
Chain FORWARD (policy ACCEPT)<br>
target prot opt source destination<br>
ACCEPT tcp -- anywhere 172.17.0.65 tcp dpt:http<br>
ACCEPT all -- anywhere anywhere ctstate RELATED,ESTABLISHED<br>
ACCEPT all -- anywhere anywhere<br>
ACCEPT all -- anywhere anywhere<br>
<br>
Chain OUTPUT (policy ACCEPT)<br>
target prot opt source destination<br>
---------------<br>
<br>
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.<br>
<br>
The dockerfile/nginx works perfect when I curl at it at port 80.<br>
<br>
I’m stumped for ideas, please help!<br>
<br>
Thanks,<br>
<br>
Chris<br>
