Accessing host variables directly in python module

[Miroslav Hudec]

Hi everyone,

first of all, I am sorry if this is documented somewhere else.

I am trying to write few modules which would be used for configuring MikroTik devices over API. My "problem" is, that in playbooks I always have to use at least 3 always-the-same arguments for each module. For example:

- name: Mikrotik TEST
  hosts: mikrotik
  connection: local
  gather_facts: no
  vars:
    dhcp_pool: testpool
  tasks:
  - name: DNS Setup
    mt_dns: username={{username}} hostname={{hostname}} password={{password}} servers=192.168.1.1
  - name: IP address setup
    mt_ip: username={{username}} hostname={{hostname}} password={{password}} address=192.168.2.1/24 interface=ether10-slave-local disabled="false"
  - name: DHCP Pool Setup
    mt_ip_pool: username={{username}} hostname={{hostname}} password={{password}} pool_name={{dhcp_pool}} pool_range=192.168.2.10-192.168.2.20
  - name: DHCP Server Setup
    mt_dhcp_srv: username={{username}} hostname={{hostname}} password={{password}} name=TestServer address_pool={{dhcp_pool}} disabled="false" interface=ether10-slave-local
  - name: DHCP Options Setup
    mt_dhcp_network: username={{username}} hostname={{hostname}} password={{password}}

In my opinion, this makes the playbook a bit confusing.. Is there any way how to make ansible push host variables right into module, without the need to call them from playbook? Using either hosts file or host_vars directory? Or is this a no-go for ansible and could only by done outside ansible? I am new to ansible and will appreciate any advice. Thanks
