Strange deprecation warning wanting me to turn an equality statement into something that returns a boolean?

[Kurtis Rainbolt-Greene]

[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.

V/r,

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.
