Module Parameter Defaults (or Module Shortcut/Alias) ?

[dennis.b...@sap.com]

Hello List,

is it possible to set defaults for the parameters of a module? Or create a shortcut/alias?

For example if I have to execute several uri calls with the same url. In case they are next
to each other you can use a loop but otherwise you have to specify the same parameters
again and again.


Thanks,

This is technically feasible now, but it isn't specifically ansible functionality, instead it is YAML functionality.  Here is an example playbook that displays how this works:

---

- hosts: all

  gather_facts: false

  vars:

    - uri_defaults: &URI_DEFAULTS

        url: "http://httpbin.org/get"

        method: GET

  tasks:

    - uri:

        << : *URI_DEFAULTS

        status_code: 200

    - uri:

        << : *URI_DEFAULTS

        status_code: 201

      ignore_errors: true

    - uri:

        << : *URI_DEFAULTS

        url: "http://httpbin.org/status/201"

        status_code: 201

This uses YAML aliases, anchors, and merge functionality.
