How to examine Jinja output in Saltstack?
Check out the slsutil.renderer module.

This should do what you want

salt my-minion-id slsutil.renderer /srv/salt/network/init.sls 'jinja'


This module just calls the compile_template function directly for you.

Edit: /srv/salt/network/init.sls is the path on the minion, if you are not targeting the master as your minion, you will probably need to do the following.

salt minion-id cp.cache_file salt://network/init.sls
salt minion-id slsutil.renderer /var/cache/salt/minion/files/base/network/init.sls


or point to whatever file that cache_file spits out.

If you are on 2018.3 or newer, you can just specify salt://network/init.sls
