I am trying to come up with a play book to install cassandra. Here each
node has a calculated token (not a random hash) and is unique. So, I have
defined a dictionary in the vars/cassandra_variables.yml as below. The IPs
192.168.56.x happen to be the ansible_inventory hosts which are defined in
the inventory file as [cassandrahosts]
How would I access the dictionary through jinja2 template.?
vars/cassandra_variables.yml
tokens:
192.168.56.1: 0
192.168.56.2: 56713727820156410577229101238628035242
192.168.56.3: 113427455640312821154458202477256070485
192.168.56.x hosts are coming in from inventory file and in the
"cassandra.j2" I have the following
initial_token: {{ tokens['{{ inventory_hostname}}'] }}
tokens["{{ inventory_hostname}}"] is evaluated but not {{ tokens['{{
inventory_hostname}}'] }}
How do I get it to work? Where am I going wrong? Any help is much
appreciated.
