Hi,
.I#m having a problem supplying a dictionary as parameter to a role. Seems
it's converted to Unicode and don't know how to proceed. The basic idea is
to have a task separated in a role and call it with different input
parameters during the playbook. Looks like when assigning a parameter using
"{{ }}" I almost got where I want to go (iterate over the supplied param
dict), but somehow I'm unable to do that?!
Any hint greatly appreciated!
Thanks,
Andreas
Test-inventory:
ansible@test:~$ cat test_inv.yml

otv_extended: true
3802:
name: TEST-VLAN-3802
otv_extended: true

hosts:

Playbook:
ansible@test:~$ cat test_pb.yml

Running the Playbook shows the following output:
