Which are not part of original jinja filters. I have the ip address and additional configuration in pillar.

See the escaping section of jinja's documentation to learn more.

Saltstack jinja template example. Saltstack jinja template pillar merge. The jinja template associated with this file will contain the basic rules, but we want to allow some other states to add instructions on this virtualhost. So to make our example more readable, we could add a single minus.

A jinja template can contain variables or expressions ideally these are placeholders expressed with {{}} which will get replaced with the actual dynamic values when it renders the page on the browser. This write up is to give you some tips and insights that i could have used when i started templating myself. It is recommended that you begin there.

Using saltstack (as a complete newbie), i need to deliver a java properties file on the target. Templating in saltstack is an absolute joy. Jinja is a template engine for python.

Jinja variable 'salt' is undefined. See the escaping section of jinja's documentation to learn more. Jinja gives us a nice way to remove white space.

Importing in jinja is similar to importing in python. Viewed 1k times 1 i have a several pillars and i am trying to merge them in the same jinja variable. With the home dir of /var/lib/example…

There will be a template for this file (i presumed the best template format would be jinja) and a collection of key/value pairs to populate it. Adds new understanding jinja topic, and fixes several jinja doc issues. The mysql_privs() macro is defined in the db_macro.sls file.

The map file is a file that can contain yaml, json or jinja and the data from the file can be imported into a state and/or into a template. Removes the full list of builtin. from each module reference list, leaving just the module type for scanability. We'll see theses states later.

This is a quick example to show how you can use jinja files to have sane default which can then be overwritten by pillar data. We start by the end, with this state building a virtualhost file in a example_com_apache_virtualhost.sls file: For example i needed to extend replace function in jinja which doesn't support regex (also i added match with regex too).

Raw blocks are necessary here because the jinja in the pillar would be rendered before. It is similar to the django template engine. Ask question asked 2 years, 7 months ago.

But instead creating a jinja custom filter, i did create a simple saltstack module to do that. After walking you through an easy way to render templates. Pillars are sets of data that we can push to the minions and then consume in state or managed files.

A template engine or template processor is a library designed to combine templates with a data model to produce documents. I understand a formula as a complete, independent set of saltstack state and configuration template files sufficient to configure a system.a system could be something as simple as an ntp server or some other much more complex service that requires many state and configuration template files. The template override and files switch (tofs) pattern ¶.

In this article, i will first put some data in the pillar and show you how to use it in a template… The template is then imported to the db variable in the db_privs.sls state file and is used to create a mysql grants state for a specific user. I'm splitting up the states, configs, and adding some default values that need to be maintained in the same config value across all enviornments.

Here's an example of my pillar: This simple module is just using default python regex module to achieve that goal. Let’s take a quick look at how we can start using pillars and templates.

When you couple this with the ability to template with jinja, it becomes very powerful. This part of the tutorial will cover more advanced templating and configuration techniques for sls files. Jinja2 is a template engine written in pure python.

{% endif %} so before writing your own stuff, check first all what saltstack provides like states, modules, grains. Another nice example is saltstack custom jinja filters. Active 2 years, 2 months ago.

Jinja2 jinja2 is a modern templating language used in python. {% if 'linux' | regex_match('.*?n.x', ignorecase=true) %} yay! Raw blocks are necessary here because the jinja in the pillar would be rendered before.

Refer to the imports and includes section for more information on importing templates and variables. Here is an example for regex_match custom filter. Saltstack also has the concept of pillars.

Refs saltstack#12470 refs saltstack#10206 refs saltstack#10480 refs saltstack#23522 refs saltstack. Template engines are often used to generate large amounts of emails, in source code preprocessing, or producing dynamic html pages. Jinja supports different kinds of constructs for example.

Currently, we have mostly hardcoded template files per environment that are matched to each environment with jinja in the init states. This tutorial builds on topics covered in part 1 and part 2. The saltey way of doing this is typically in a map.jinja file.

If you know otherwise then i would be interested to see an example (specifically with jinja that produces a broken state) because an irksome thing with cp.get_template is that it requires an output fd and so it isn't effective when called by salt from a master as /dev/stdout isn't available. Jinja2 templating provides a process by which you can create content for files using smaller code blocks to generate content dynamically. With no pillar data the state will do the following:

What i'd like to do is generate multiple configuration files for each openvpn user.
