> 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
> Fix For: 4.4.3, 4.3.9
>

> 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:
> *working* version, docker network=host
> {code:java}
> docker run -it -d --name=test.4.4.2 --network=host -e ORG_APACHE_KARAF_MANAGEMENT_RMIREGISTRYHOST='172.21.51.155' -e ORG_APACHE_KARAF_MANAGEMENT_RMISERVERHOST='172.21.51.155' -e KARAF_DEBUG=true -p 1099:1099 -p 44444:44444 apache/karaf:4.4.2{code}
