Ansible community.rabbitmq can't use RABBITMQ_USE_LONGNAME

[kost1993]

SUMMARY

There is a problem with cluster which uses longnames in rabbitmq cluster. For now there is no possible way to use any play against such clusters. There is no such option in plugins and possible life hacks such as setting remote environment doesn’t work.
For instance: rabbitmqctl can be used in bash with longnames:

sudo RABBITMQ_USE_LONGNAME=true [email protected] rabbitmqctl ...
or
sudo rabbitmqctl --longnames [email protected] ...

But in the rabbitmq_user.py of ansible collection there is no possible way to use such option for longnames.
In definition _exec

community.rabbitmq/plugins/modules/rabbitmq_user.py

Line 285 in 65b0022

def _exec(self, args, check_rc=True):

it can use flag --node but not --longnames.

For me it works as of today:

$ lsb_release -a
No LSB modules are available.
Distributor ID:	Debian
Description:	Debian GNU/Linux 12 (bookworm)
Release:	12
Codename:	bookworm

$ ansible --version
ansible [core 2.14.3]

(from debian repos)

$ ansible-galaxy collection list community.rabbitmq
Collection         Version
------------------ -------
community.rabbitmq 1.3.0 

(not from debian repos, from galaxy, because of login_user)

The only trick that's left, is that you have to set the node explicitely:

    rabbitmq_user:
        node: "rabbit@{{ rabbitmq_nodename }}"

whereby rabbitmq_nodename is some fqdn.

And I specified RABBITMQ_USE_LONGNAME=yes in /etc/rabbitmq/rabbitmq-env.conf

So maybe you want to close this issue?
