You could use set_fact: stanzas instead, with when: clauses.
- set_fact:
user_list: 'user1, user2, user3'
when: server_type = 'db_server'
Even better, use lists rather than strings. You can always turn one into
the other, and lists are more flexible:
- set_fact:
user_list: ['user1', 'user2', 'user3']
when: server_type = 'db_server'
Or something like this:
vars:
db_users: ['user1', 'user2', 'user3']
web_users: ['user4', 'user5', 'user6']
standard_users: 'user7', 'user8', 'user9']
- set_fact:
user_list: "{{ db_users }}"
when: server_type = 'db_server'
Or this:
vars:
user_groups:
{
'db_server': ['user1', 'user2', 'user3'],
'web_server': ['user4', 'user5', 'user6'],
'standard_server': ['user7', 'user8', 'user9']
}
- set_fact:
user_list: "{{ user_groups[ server_type ] }}"
The syntax is off the top of my head so probably full of errors, but it
should give you some ideas.
