I have several states that are almost the same. All of them deploy project, create virtualenv and configure supervisor. Difference is only in repo, project name and some additional actions.
A lot of code is duplicated. Is it possible to put the same parts into file and include it with additional variables?
In Ansible it can be done this way:
tasks:
- include: wordpress.yml
vars:
wp_user: timmy
ssh_keys:
- keys/one.txt
- keys/two.txt
This question looks similar to this one
If I understood your question correctly - I believe the best way to achieve what you want is to use Salt Macros.
With this most of your state will go to macros with placeholders being parameters like:
# lib.sls
{% macro create_user(user, password) %}
{{user}}:
user.present:
- home: /home/{{user}}
- password: {{password}}
{% endmacro %}
Then your state will look like:
# john.sls
{% from 'lib.sls' import create_user with context %}
{{ create_user('john', '<password hash>') }}
and:
# jane.sls
{% from 'lib.sls' import create_user with context %}
{{ create_user('john', '<password hash>') }}
As I found out there is another way to archive it without messing with templates (more Ansible way). Create an abstract state "python-project". Create concrete roles then and provide different pillars to these roles:
salt/top.sls:
base:
'roles:python-project-1':
- match: grain
- python-project
'roles:python-project-2':
- match: grain
- python-project
pillar/top.sls:
base:
'roles:python-project-1':
- match: grain
- common-pillars
- pillars-for-the-first
'roles:python-project-2':
- match: grain
- common-pillars
- pillars-for-the-second
Structure:
pillar/top.sls
pillar/common-pillars/init.sls
pillar/pillars-for-the-first/init.sls
pillar/pillars-for-the-second/init.sls
salt/top.sls
salt/python-project/init.sls
You can use Jinja imports to do that:
top.sls
{% set user = 'john' %}
{% include 'config.sls' %}
config.sls
file.managed:
- name: '/Users/{{ user }}/.config
- user: {{ user }}
