Run a module locally

Question

I'm developing a smoke test playbook which simply goes through and ensures that I get a HTTP 200 out of all of our servers.

I was originally doing this:

---
- hosts: prod
  gather_facts: no
  tasks:
      - name: smoke test
        uri: url=http://{{ inventory_hostname }}/ status_code=200

The problem here is that these servers apparently don't have httplib2 installed on them, so the URI command fails.

Is there a way for me to run the uri module on my local machine to the remote machines to just run through all of them and curl each one? I'd like to use a module if possible, because it's easier to check that the return code is exactly what I want.

Answer 1

You can delegate any task to localhost or another remote host with delegate_to:

- name: smoke test
  uri: url=http://{{ inventory_hostname }}/ status_code=200
  delegate_to: localhost

Also, there is the local_action module, but I prefer the delegate_to way.

- name: smoke test
  local_action: uri url=http://{{ inventory_hostname }}/ status_code=200
