[DEPRECATION WARNING]: evaluating node\_leader\_hostname == service\_fqdn.stdout as a bare variable, this behaviour will go away and you might need to add |bool to the expression  
in the future. Also see CONDITIONAL\_BARE\_VARS configuration toggle… This feature will be removed in version 2.12. Deprecation warnings can be disabled by setting  
deprecation\_warnings=False in ansible.cfg.

Here’s the step:

- name: Determine if leader  
set\_fact:  
node\_leader: node\_leader\_hostname == service\_fqdn.stdout

Does anyone have any idea what it’s talking about?

The value is a string that looks like a boolean. Today, ansible does magic to turn it into a boolean, but in the future, it won't.

Ah, I thought that might be it, however when I changed to:

node\_leader: node\_leader\_hostname == service\_fqdn.stdout | bool

Like it suggested it still complained.

Indeed, the real problem is that you're setting the fact to the literal string `node_leader_hostname == service_fqdn.stdout | bool`.

You need jinja braces: `"{{ node_leader_hostname == service_fqdn.stdout }}"`

Ah, okay, that makes sense now.
