deprecation warnings: evaluating [] as a bare variable

[tmtron]

sorry for my newbie question, but I am not sure, if I can change my config to get rid of these warnings, or if these warnings are okay for now and need to be fixed in this role.

in my playbook I try to deactivate the default cron job like this:

  vars:
    docker__cron_jobs: []

then I get this warning:

TASK [nickjj.docker : Configure Docker daemon environment variables] ***************************************************
[DEPRECATION WARNING]: evaluating [] 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.

There is also another warning like this, which seems not related to my config:

TASK [nickjj.docker : Configure Docker daemon options (flags)] *********************************************************
[DEPRECATION WARNING]: evaluating [u'-H unix://'] 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.

Hi,

Those are fixed on the master branch. I suppose it's about time I make a new release.

Edit: I just pushed v1.9.0 to the Galaxy which has these fixes and more.

thanks for the fast feedback and new release.
I've already upgraded to v1.9.0 and can confirm that the warnings are gone.
