How to get minion id from jinja script inside a salt state

I need to apply a if-else logic based on a static minion id inside a state file. The target glob qualifies a whole bunch of servers, but I need to run a small piece of logic on a single server and run a bunch of common things on all of them. How can I do this?

When I put this in a Jinja file, its errors:

{% import salt.config %}
{% minion_opts = salt.config.minion_config('/etc/salt/minion') %}
{% print(minion_opts['id']) %}
{% if minion_opts['id'] == 'xyz.server': %}
-- run the logic here
..
..

Error:

- Rendering SLS 'base:bin.test' failed: Jinja syntax error: expected token 'as', got 'end of statement block'; line 1  
-  
- ---  
- {% import salt.config %}    <======================  
- {% minion_opts = salt.config.minion_config('/etc/salt/minion') %}  
- {% print(minion_opts['id']) %}

It probably goes without saying I am not a Saltstack expert by any means.

So first off, I realize this is an old question, but it still shows up at the top of the my search results for both DDG and Google for a somewhat related problem and the current answers don't really deliver on the ask, so here's an answer based off the latest SaltStack version (3002):

In order to get control flow working for Jinja based off minion id:

{% if salt['grains.get']('id') == 'minion_a' %}
some text to render for minion_a
{% else %}
some text to render otherwise
{% endif %}

I realize there were other issues in how the question was phrased and for the sample code provided, but my code snippet answers the actual question of:

I need to apply a if-else logic based on a static minion id inside a state file.

How can I do this?

The error occurs because you're using Jinja's import in an unexpected way. If this is a Flask app, you should use something like this in your views.py route to provide variables to the template:

render_template('my_template.html', salt=salt)

The corrected code should look something like this:

{% set minion_opts = salt.config.minion_config('/etc/salt/minion') %}
{{ minion_opts['id'] }}
{% if minion_opts['id'] == 'xyz.server' %}
  {{ 'logic goes here' }}
{% endif %}

See the Assignments docs on how to assign values to variables.

No colon is necessary at the end of the if statement, and remember to use {% endif %} after you're done with your conditional statements.
