I need to exclude certain minions marked with either of these custom added grains from getting a software installation Salt state:

exclude:
  - applications
  - application_xyz

The following syntax that works, and prevents any minions with the "applications" grain from installing anything:

{% if not "applications" in grains.get('exclude', []) %}

But now I need to get more specific, and that's where I thought using "or" logic made sense. So far I've tried the following, neither of which work:

{% if not "applications" or "application_xyz" in grains.get('exclude', []) %}

{% if not "applications" in grains.get('exclude', []) or not "application_xyz" in grains.get('exclude', [])  %}

I used How to use logic operators in jinja template on salt-stack (AND, OR) as some reference, so I feel that I may be on the right track.

Any help or advice is hugely appreciated!

    To my eyes, the first approach is syntactically incorrect. The second looks syntactically correct, but has error in logic. One of De Morgan’s laws states: `not (A or B) = not A and not B`. For reference, see https://en.wikipedia.org/wiki/De_Morgan%27s_laws – Lesiak Dec 01 '20 at 19:51

For anyone who runs into the same situation I've found that the following works perfectly.

{% if not ['applications','application_xyz'] | intersect(grains.get('exclude', [])) %}

Here, any minions with either applications, or application_xyz will be passed over.
