localhost
Make sure you have localhost in the juniper group in your inventory.
[duchess@cody:tmp] cat group_vars/juniper
---
username: admin
password: This is not a good password.
...
And if you're going to use group variables you need to place them in the correct group.
[duchess@cody:tmp] cat playbook.yml
---
- name: Execute a show command on a junos device.
hosts: juniper
gather_facts: no
connection: local
tasks:
- name: Define the provider.
set_fact:
hostinfo:
host: "{{ inventory_hostname }}"
password: "{{ password }}"
username: "{{ username }}"
- name: Output the hostname.
debug:
var: hostvars[inventory_hostname]
# I don't have a junos device handy so I can't test this, but. . .
#- name: show command
# junos_command:
# provider: "{{ hostinfo }}"
# commands:
# - show version
# register: version
#- name: Output the version.
# debug:
# var: version
- name: Output the username and password from group_vars/juniper.
debug:
msg: "The username is {{ username }}. The password is '{{ password }}'."

Please excuse the odd indentation, the code macro in Google Groups doesn't seem to like yaml very much.
