Jira Clustering In Docker Containers

[Xavier]

I'm trying to set up a jira cluster, running in docker containers across two VMs. After initial setup, I can see the successful creation of the cluster in the GUI,  but when I check the logs of node 2, its trying to connect to the DOCKER IP of node 1, and not the host IP. Here's an example error:

2026-01-07 18:41:03,225+0000 localq-reader-17 INFO [c.a.j.c.distribution.localq.LocalQCacheOpReader] [LOCALQ] [VIA-COPY] Checked exception: RecoverableFailure occurred when processing: LocalQCacheOp{cacheName='com.atlassian.cluster.monitoring.spi.ClusterMonitoring.cache', action=PUT, key=CustomSerializedValue{value=nodeKey{nodeId='jira-2', key='com.atlassian.cluster.monitoring.cluster-monitoring-plugin:system-information'}, isValueSerializable='true', pluginKey='com.atlassian.jira.jira-cluster-monitoring-plugin'}, value == null ? false, replicatePutsViaCopy=true, creationTimeInMillis=1767811258215} from cache replication queue: [queueId=queue_jira1_7_3c177fc9a73549bf63b836dc4124cadc_put, queuePath=/var/atlassian/application-data/jira/localq/queue_jira1_7_3c177fc9a73549bf63b836dc4124cadc_put], failuresCount: 1. Will not retry as this is a cache replicated by value. Removing from queue.
com.atlassian.jira.cluster.distribution.localq.LocalQCacheOpSender$RecoverableFailure: java.rmi.ConnectIOException: Exception creating connection to: X.X.X.X; nested exception is:

That X.X.X.X IP is the docker container IP, but it should be the host IP. I can see why this happening because the /etc/hosts file on the container has the following entry which needs to be removed:

127.0.0. localhost

The problem is that I cannot remove this entry inside of the container.  I read a post from a user, who set up a clutser where both nodes(containers) were on the same VM, but I'm trying to get this working across seperate VMs.

Thanks!
