Hi Tomas,
Running multiple instances of EAP on one host is fairly easy, but does
requires to get all the details right.I made an Ansible demo to showcase
this exact use case
<
https://github.com/ansible-middleware/wildfly-cluster-demo>. You may even
be able to reuse the automation.
In short, in this demo, I keep the standalone.xml in the
standalone/configuration folder, but data, tmp and log are instance
specific and located elsewhere.

Hello,
could anybody confirm if it's OK (or not OK) to run multiple clustering
Wildfly instances that would share common standalone/ directory? Even if
the instances are supposed to be running the same deployments?
I always thought that the standalone/ directory should be separate for
each Wildfly/EAP instance, but I can't find any resources that would
clearly state that shared standalone/ is a problem.
The problems I think of are:
* instances could override their standalone.xml config,
* instances could override some transactional or cache data?
Thanks :),
Tomas
