Super simple show version task

gistfile1.txt

---
- hosts: ios_routers
  gather_facts: false
  connection: local
  
  tasks:
   - name: run show version on ios device
     ios_command:
       commands:
         - show version
      host: "{{ inventory_hostname }}"
      username: cisco
      password: cisco

There is an extra space infront of host:, username: and password:, it should read:

  gather_facts: false
  connection: local

  tasks:
   - name: run show version on ios device
     ios_command:
       commands:
         - show version
       host: "{{ inventory_hostname }}"
       username: cisco
       password: cisco

Thanks... fixed
