Yes, the variable "role_names" contains a list of all role names, as of a
3/11 addition by Brian Coca.
You'll need the development branch.
However in most cases (but not always), it's not needed --- plays are
intended to map groups to roles, so it's intended that tests are applied
against group membership most of the time.
- hosts: webservers
roles:
- base
- webserver
- monitored
Thus if you were doing an iptables template:
{% if inventory_hostname in groups.webservers %}
Is equivalent to:
{% if 'webserver' in role_names %}
If all machines were to be monitored, it might be nice to even say this:
- host: all
roles:
- base
- host: webservers
roles:
- webserver
- host: all
roles:
- monitored
