Hi All,
I'm using a playbook to create an instance. Essentially, I've modified the
code snippet on example 4 here -> http://docs.ansible.com/guide_aws.html
>From the command_line, I pass in a variable "instance_name", which I use to
set the tags for the EC2 instance and the hostname for the instance I just
created.
The below code snippet works fine on Mac (Ansible 1.7.2), but fails on
Debian 8.0 with the same version of Ansible 1.7.2.
What am I doing wrong? Or is this something with the code?
- hosts: localhost
connection: local
gather_facts: False
vars:
instance_name: "somename"
-tasks:
--snipped--
--snipped--
# Connect to the node and gather facts, including the instance-id. These
facts
# are added to inventory hostvars for the duration of the playbook's
execution
# Typical "provisioning" tasks would go in this playbook.
- hosts: ec2hosts
gather_facts: True
user: admin
sudo: True
tasks:
# fetch instance data from the metadata servers in ec2
- ec2_facts:
# show all known facts for this host
- debug: var=hostvars[inventory_hostname]
# just show the instance-id
- debug: msg="{{
hostvars[inventory_hostname]['ansible_ec2_instance_id'] }}"
- name: set hostname to {{ instance_name }}
hostname:
name: "{{ instance_name }}"
The error I get on debian is:
TASK: [set hostname to {{ instance_name }}]
***********************************
fatal: [54.xx.xx.xx] => One or more undefined variables: 'instance_name' is
undefined
FATAL: all hosts have already failed -- aborting
PLAY RECAP
********************************************************************
On the Mac (Yosemite), this part goes without any incident:
TASK: [set hostname to somename]
*************************************************
changed: [54.xx.xx.xx]
