Do you have all 3 groups in the inventory? > \*inventory:\* > > [cent7local] > 192.168.1.86 > 192.168.1.77 > .... Here you only list one of the groups, your code need all 3 defined to work. If this is not the case you need to filter it with default() > So the main question - how could I use the condition like: > "inventory\_hostname in groups.cent6local or inventory\_hostname in > groups.cent7local or inventory\_hostname in groups.ubuntulocal" ? Was it > changed? The functionality have not changed. But newer Ansible is more restrictive, before it ignored some errors but newer version fails instead, since that's more sane. But a few error message is not that informative, but it's getting better.
