Can anyone help me with the below, maybe my approach is wrong. What I’m
trying to do is to create from a template a keepalived file based on the
elements in a dictionary.
I’ve included the code below, when its ran the error that appears is
msg": "AnsibleUndefinedVariable: 'dict object' has no
attribute 'hostname'"
The error appears to in the second loop in the jinja2 template, where i try
to extract the elements from the sub lst in the dictionary.
