In Jinja2 loops and conditionals come under name of control structures, since they affect flow of a program. Control structures use blocks enclosed by {% and %} characters. Loops. First of the structures we'll look at is loops. Jinja2 being a templating language has no need for wide choice of loop types so we only get for loop. For loops start with {% for my_item in my_collection %} and end. loop.previtem. The item from the previous iteration of the loop. Undefined during the first iteration. loop.nextitem . The item from the following iteration of the loop. Undefined during the last iteration. loop.changed(*val) True if previously called with a different value (or not called at all).

It's really important to know how Jinja2 works if you want to create powerful templates for your playbooks. Today we're gonna work with: loop.index: The current iteration of the loop. (1 indexed) loop.length: The number of items in the sequence Two different examples for different files: /etc/hosts and workers.properties: /etc/hosts We want to generate the following sni In our example we see that because we can't call the variable outside of the inner loop, the counting didn't work. A quick modification to your /etc/ansible.cfg file and a small change to your template, and we can get this working. First, add the following line to your ansible.cfg:--- [defaults] jinja2_extensions = jinja2.ext.do,jinja2.ext.i18 Welcome to Jinja2¶.

Jinja2 templating can also be used with conditional statements such as for loops to iterate over a list of items. Consider the Playbook example2.yml as shown in the pictorial below: We are going to create a template that will iterate over the list of car models called 'cars' and print the result in the file2.txt destination file Files for Jinja2, version 2.11.2; Filename, size File type Python version Upload date Hashes; Filename, size Jinja2-2.11.2-py2.py3-none-any.whl (125.8 kB) File type Wheel Python version py2.py3 Upload date Apr 13, 2020 Hashes Vie Loops¶. Sometimes you want to repeat a task multiple times. In computer programming, this is called a loop. Common Ansible loops include changing ownership on several files and/or directories with the file module, creating multiple users with the user module, and repeating a polling step until a certain result is reached.Ansible offers two keywords for creating loops: loop and with_<lookup>

Using 'for' loop structure inside Ansible template. One of the main program expression we usually use is the 'for' loop. It can be used to iteratively go through the values of a list, dictionary etc. It is possible to use this in ansible templates also using the jinja2 format
Running a for-loop over a Jinja2 dictionary At the time of this posting, iterating over dictionaries inside a Jinja template is poorly documented, especially if you need access to the jinja dictionary keys and it's something I end up doing alot. Of course running a for-loop over a jinja dictionary is as basic an activity as you're likely to do, for whatever reason it's buried in the Jinja2.
> imagine jinja2 lighter? > Yes, jinja2 is a new language, it's not exactly the same syntax as python. Using | and filters is one of the big differences. Jinja is inspired by django's template system, which was very restrictive and meant to be friendly for designers (who don't know python) to use
Jinja2 for better Ansible playbooks and templates. 08/25/14 by Daniel Schneller. 4 Comments . There have been posts about Ansible on this blog before, so this one will not go into Ansible basics again, but focus on ways to improve your use of variables, often, but not only used together with the template module, showing some of the more involved features its Jinja 2-based implementation offers.

Jinja2 Namespaces and Variable Scope. I have been doing some Network automation lately, specifically using the Juniper vSRX and generating config templates via Ansible. I quickly found out about variable scope in Jinja. Please keep in mind that it is not possible to set variables inside a block and have them show up outside of it. This also applies to loops. The only exception to that rule are. Welcome to a Flask tutorial covering a bit more about Jinja. We covered more of the Jinja basics earlier in this tutorial.This tutorial is a quick overview of the points I find to be most important from the Jinja documentation, that I have not yet covered in the earlier tutorials.Just like I recommend scrolling through the Bootstrap documentation once in a while, you should do the same here python-jinja2_2.10-1_all.deb: small but fast and easy to use stand-alone template engine: Ubuntu Main i386 Official: python-jinja2_2.10-1_all.deb: small but fast and easy to use stand-alone template engine: Ubuntu Updates Main amd64 Official: python-jinja2_2.10-1ubuntu0.18.04.1_all.deb: small but fast and easy to use stand-alone template engin Loop over Ansible variable array in Jinja2 template. Ask Question Asked 3 years ago. In a template I want to loop over all the objects in the array and output the values of each mount key. I try it like this: (% for mounts in {{ ansible_mounts }} %) Mountpoint: {{ ansible_mounts.mount }} (% endfor %) But it does not work. I tried around with some other stuff like iteritems() but I cannot.
