supply dict as parameter to role
andyb...@googlemail.com
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
