Jean-Baptiste Onofré commented on KARAF-7610:
---------------------------------------------
I'm not able to reproduce the issue neither with Karaf 4.3.7 docker image or
Karaf 4.4.2 docker image.
Here's the steps I did:
# I created a new bridge network named {{{}karaf-test{}}}:
{code:java}
$ docker network create karaf-test
$ docker network ls
NETWORK ID NAME DRIVER SCOPE
25db086ae405 bridge bridge local
ebb62471d41a host host local
d2b4fe1e52dc karaf-test bridge local
ba5636bf592c minikube bridge local
11f7808e089a none null local{code}
2. I run docker container like this:
{code:java}
$ docker run -it -d --name=test --network=karaf-test -p 1099:1099 -p
44444:44444 apache/karaf:4.4.2{code}
3. Then, I "connect" to the test container with:
{code:java}
$ docker exec -it test /bin/bash {code}
to:
* {{edit /opt/apache-karaf/etc/org.apache.karaf.management.cfg}} with
{{rmiRegistryHost=0.0.0.0}} and {{rmiServerHost=0.0.0.0}}
* {{edit /opt/apache-karaf/etc/users.properties}} to enable karaf user and
group
4. {{docker inspect}} gives me the IP address of the container, e.g.
{{"IPAddress": "172.18.0.2"}} in my case
5. I can connect jconsole without problem on
{{service:jmx:rmi:///jndi/rmi://172.18.0.2:1099/karaf-root}}
Can you share the difference in your setup ? Maybe the docker network type ?

> Key: KARAF-7610
> URL: https://issues.apache.org/jira/browse/KARAF-7610
> Project: Karaf
> Issue Type: Bug
> Affects Versions: 4.2.16, 4.3.8, 4.4.2
> Environment: Debian 11.3
> Docker version 20.10.17, build 100c701
> Reporter: Ondrej Mrekaj
> Assignee: Jean-Baptiste Onofré
> Priority: Major
>
> We noticed a problem with access to JMX in the case that karaf is running in
> a docker container and uses a different network than the host. Last versions
> of apache karaf where were working example below are 4.3.0, 4.2.11.
> The given problem does not allow us to use JMX monitoring and simultaneously
> separate individual docker networks from the host network.
> Please see example below:
