Append new key value pair with correct indentation in yml file

[Shivani Arora]

Hi,

I'm trying to append new key-value pair in the existing yml (subcluster_to_subnet_map.yml)  file using combine.  New values are getting appended correctly but it's getting added without spaces. 

I need help with adding 2 spaces in starting so that the indentation is maintained. Please suggest how this can be achieved. (I don't want to use lineinfile here)

Yaml file on which key-value pair should be added: subcluster_to_subnet_map.yml

subcluster_to_subnet_map:
    ee: ee-ci9-sc8
    test: test-ci1-sc1

    <<new value should have 2 spaces>>

I'm using below code for this -

        - name: append new subnet and subcluster values
          set_fact:
            subcluster_to_subnet_map: "{{ subcluster_to_subnet_map | default({}) | combine ({input_subcluster: input_subnet}) }}"

        - debug:
            var: subcluster_to_subnet_map

        - name: write var to file
          copy:
            content: "{{ subcluster_to_subnet_map | to_nice_yaml }}"
            dest: environment/subcluster_to_subnet_map.yml

The output I'm getting now is -

subcluster_to_subnet_map:
    ee: ee-ci9-sc8
    test: test-ci1-sc1
test1: infra-nodes

Hi Team,

Looking forward to any input.

Thanks

Where are these variables defined?

subcluster_to_subnet_map
input_subcluster
input_subnet

Please share the complete playbook and variables.

I'm taking user input for variables: input_subcluster, input_subnet and subcluster_to_subnet_map is defined in subcluster_to_subnet_map.yml file. 

Here is my code -

- hosts: localhost
  connection: local
  gather_facts: True

#
## Taking inputs for subcluster and subnet
#
  vars_prompt:
  - name: "input_subcluster"
    prompt: "Enter subcluster name"
    private: no

  - name: "input_subnet"
    prompt: "Enter subnet name"
    private: no

  - include_vars:

           file:  environment/Dev/subcluster_to_subnet_map.yml

           name: subcluster_to_subnet_map

  - name: append new subnet and subcluster values

     set_fact:
           subcluster_to_subnet_map: "{{ subcluster_to_subnet_map | default({}) | combine ({input_subcluster: input_subnet}) }}"

   - debug:
          var: subcluster_to_subnet_map

   - name: write var to file
     copy:
          content: "{{ subcluster_to_subnet_map | to_nice_yaml }}"

          dest: environment/Dev/subcluster_to_subnet_map.yml

=============================================

Location and content of subcluster_to_subnet_map.yml file:  environment/Dev/subcluster_to_subnet_map.yml

subcluster_to_subnet_map:
    ee: ee-ci9-sc8
    test: test-ci1-sc1

    <<new value should have 2 spaces>>

This means the content of subcluster_to_subnet_map variable, which does
not include its own name. You should explicitly write that out.
Try this:

content: "{{ {'subcluster_to_subnet_map': subcluster_to_subnet_map} |

to_nice_yaml }}"

It gave the below output:

subcluster_to_subnet_map:

    subcluster_to_subnet_map:
        ee: ee-ci9-sc8
        test: test-ci1-sc1
    test1: infra-nodes

The expected output is:

subcluster_to_subnet_map:

   ee: ee-ci9-sc8

   test: test-ci1-sc1

   test1: infra-nodes
