Ansible 2.8.0: Module option conversion to string

[tendo...@gmail.com]

Ansible 2.8.0 has introduction Module option conversion to string but didn't give any example. I have simple task to set the file descriptor limits for user

- name: Set file descriptor limits for the node user

  pam_limits:

    domain: app

    limit_type: "{{ item }}"

    limit_item: nofile

    value: 65535

  loop:

    - soft

    - hard

It was working fine and didn't give any warning until 2.7.x but after upgrading to ansible 2.8.0, I am getting this warning:

 [WARNING]: The value 65535 (type int) in a string field was converted to '65535' (type string). If this does not look like what you expect, quote the entire

value to ensure it does not change.

I have changed the value part like this:

 value: !!int 65535

But still get the same warning. How I can overcome this warning. Thanks

that's not true: Ansible has already been doing that for a long time.
It's only since 2.8.0 that Ansible will warn about such conversions
-- which can be really dangerous, in particular in combination with
booleans.

Not a surprise, since 65535 is still an integer. The "value" option
expects a string.

So you have to quote the value (as the warning says) to make it a
string:

> pam_limits:
> domain: app
> limit_type: "{{ item }}"
> limit_item: nofile
> value: "65535"
