SaltStack how do I repeat other states with context

Question

I’ve created a state for API

 I would like to turn it into a template and execute it several times per minion, with variables supplied from pillar - i.e something like.

    {% for apiserver in pillar.apiservers %}

      include apiserver_template.sls, locals: apiserver.config

    {% endfor %}

where apiserver_template will work with context supplied to it, with apiserver.config having all config data for each API instance. I know syntax is wrong but hopefully I am communicating the idea - ideally, something like executing ruby partials with supplying local variables.

How is it done properly in saltland?

In your case it’ll look something like this

 

{% macro api_server(git_repo, python_venv_path, python_venv_requirements) %}

{{python_venv_path}}:

  virtualenv.managed:

    - system_site_packages: False

    - requirements: salt://{{python_venv_requirements}}

 

{{git_repo}}:

  git.latest:

    - name: {{git_repo}}

{% endmacro %}

 

Assuming you have a pillar apiservers where each api server has git_repo, python_venv_path and python_venv_requirements values, you can use the macro like this:

{% for server in salt.pillar.get('apiservers', []) %}

{{ api_server(server['git_repo'], server['python_venv_path'], server['python_venv_requirements']) }}

{% endfor %}
