Turns out that + and – are there for whitespace control purpose. You can manually disable the lstrip_blocks behavior by putting a plus sign (+) at the start of a block […] You can also strip whitespace in templates by hand. If you put an minus sign (-) to the start or end of an … Read more
If you really want to append to content, you will need to use the set_fact module. But if you just want to use the merged lists it is as easy as this: {{ list1 + list2 }} With set_fact it would look like this: – set_fact: list_merged: “{{ list1 + list2 }}” NOTE: If you … Read more
There is whitespace control in Jinja2. You might want: {%- set ip = grains[‘ip4_interfaces’][‘eth1’][0] -%} {%- set domain = pillar[‘company_domain’] -%} {%- set version = pillar[‘site_version’] -%} {%- set site_url=”www.” + domain -%} […] As well, the salt configuration file supports jinja_trim_blocks and jinja_lstrip_blocks (jinja_env:trim_blocks, jinja_env:lstrip_blocks, jinja_sls_env:trim_blocks, and jinja_sls_env:lstrip_blocks as of 2018.3).
You can create a loop like this: {% for i in range(11) %} {{ i }} {% endfor %}
{% include “file” %} does this. See the jinja2 docs for more information.
I am sure there is a smarter way for doing what you want but this should work: – name : Test var hosts : all gather_facts : no vars: myvariable : false tasks: – name: param1 set_fact: myvariable: “{{param1}}” when: param1 is defined – name: param2 set_fact: myvariable: “{{ param2 if not myvariable else myvariable … Read more
When you load your jinja2.Environment, set the ‘undefined’ parameter to ‘jinja2.StrictUndefined’, e.g.: env = jinja2.Environment(loader=<someloader>, undefined=jinja2.StrictUndefined) You can catch and examine the render exception to see what was missing EDIT It would help if I read your full question. 🙂
Just pass items to template.render as a keyword argument – it should be a list (really any iterable will do) of items. If you need sub-items use a class or a dictionary. In the simplest case, you can use a dictionary: items = [] for i in range(1, 11): i = str(i) # dict == … Read more
I find the magic map extract here. main_nodes_ips: “{{ groups[‘mainnodes’] | map(‘extract’, hostvars, [‘ansible_host’]) | join(‘,’) }}” main_nodes_ips_with_port: “{{ groups[‘mainnodes’] | map(‘extract’, hostvars, [‘ansible_host’]) | join(‘:3000,’) }}:3000” An alternative(idea comes from here): main_nodes_ips: “{{ groups[‘mainnodes’] | map(‘extract’, hostvars, [‘ansible_eth0’, ‘ipv4’, ‘address’]) | join(‘,’) }}” (Suppose the interface is eth0)
I think your best bet is a combination of defined() check along with looking at the length of the array via length() function: {% if texts is defined and texts|length > 0 %} … {% endif %}
