Hyphens discouraged in the inventory group names

[Piotr Parczewski]

As per: https://docs.ansible.com/ansible/latest/network/getting_started/first_inventory.html#basic-inventory

And the warnings:

Not replacing invalid character(s) "{'-'}" in group name (chrony-server)
Not replacing invalid character(s) "{'-'}" in group name (tls-backend)
Not replacing invalid character(s) "{'-'}" in group name (tls-backend)
Not replacing invalid character(s) "{'-'}" in group name (hacluster-remote)
Not replacing invalid character(s) "{'-'}" in group name (hacluster-remote)
Not replacing invalid character(s) "{'-'}" in group name (outward-rabbitmq)
Not replacing invalid character(s) "{'-'}" in group name (outward-rabbitmq)
Not replacing invalid character(s) "{'-'}" in group name (monasca-agent)
Not replacing invalid character(s) "{'-'}" in group name (monasca-agent)

It's something to consider before upstream Ansible decides to refuse accepting such group names.

Should I replace hyphen to underscore in group names everywhere?

I guess this would affect existing users' inventory files.

Are there other implications to consider and what would be the best approach on this?

[Radosław Piliszek (yoctozepto)]

So far we have agreed to simply ignore this issue by using an appropriate ansible config file option.
