Check if all the values of a yml matches a string else throw error and exit in ansible

[BIJAY PARIDA]

Hi,

I have two files file1.yml and file2.yml which I am passing from the deployment level.

I want to verify that all the values of the file1 matches to a string else exits with error message, same with the 2nd file.

file1.yml (value field is same)

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

"item1" : "value"

"item2" : "value"

"item3" : "value"

file2.yml (value2 field is same)

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

"item1" : "value2"

"item2" : "value2"

"item3" : "value2"

Both value1 and value2 are different and I want to check the respective files and their values.

And assert the condition file1.values | uniqe == value1 

Thanks

Bijay

Not pretty but it should get the job done.

- include_vars:
file: file1.yml
name: file1

- set_fact:
file1values: "{{ file1values | default([]) + [item.1] }}"
with_items:
- "{{ file1 | dictsort }}"

- assert:
that: file1values | unique | length == 1

Thanks a lot Kai for the response. Here I don't want to include the vars, just want to check if the file exists and it contains the string.

Is there any alternate? I meant without using the include_vars option.

The length comparison works well.

But when comparing the string it fails.

     - assert:

#         that: "file1values | unique | length == 1"

         that: file1values.get('values') | unique == 'drop'  - Tried with get values.

You can always use shell

- shell: cut -f2 -d":" /path/to/file1.yml | uniq | wc -l
register: r

- assert:
that: r.stdout == "1"

file1values is a list so the get method wont work.
unique return a list of unique values of a list, ["a", "a", "b"] becomes
["a", "b"] and ["a", "a", "a"] becomes ["a"] so you can't compare that
to a string.

Thanks a lot for the help, I will take it forward from here to add some more conditional checks.
