ansible undefined variable for a play while creating an ec2 instance - amazon-web-services

Question

I am getting the undefined variable error while creating EC2 instance in AWS Cloud with Ansible playbook.
My Ansible version is 2.9.
My Playbook:
---
- name: Running AWS EC2 Play ...
hosts: localhost
connection: local
gather_facts: yes
tasks:
- include_vars: aws_vars.yml
- name: Setting up the Security Group for new instance
ec2_group:
name: "{{ aws_hostname }}-nsg"
description: Allowing Traffic on port 22 and 80
region: "{{ aws_region }}"
aws_secret_key: "{{ SecretKey }}"
aws_access_key: "{{ AccessKey }}"
rules:
- proto: tcp
from_port: 22
to_port: 22
cidr_ip: 0.0.0.0/0
- proto: tcp
from_port: 80
to_port: 80
cidr_ip: 0.0.0.0/0
rules_egress:
- proto: all
cidr_ip: 0.0.0.0/0
vpc_id: "{{ aws_vpc_id }}"
- name: Spinning up new aws ec2 instance
ec2:
aws_access_key: "{{ AccessKey }}"
aws_secret_key: "{{ SecretKey }}"
image: "{{ aws_image_id }}"
instance_type: "{{ aws_instance_type }}"
instance_tags: { "Name":"{{ aws_hostname }}", "Vendor": "Amazon" }
key_name: "{{ aws_instance_key }}"
assign_public_ip: no
count: 1
wait: yes
wait_timeout: 500
region: "{{ aws_region }}"
volumes:
- device_name: "{{ aws_device_name }}"
device_type: "{{ aws_device_type }}"
volume_size: "{{ aws_volume_size }}"
delete_on_termination: true
vpc_subnet_id: "{{ aws_subnet_id }}"
group: "{{ aws_hostname }}-nsg"
user_data: hostnamectl set-hostname "{{ aws_hostname }}"
register: ec2_result
- debug:
var: ec2_result
- name: Wait for SSH to come up
wait_for:
host: '{{ private_ip }}'
port: 22
delay: 60
timeout: 320
state: started
loop: '{{ ec2_result.instances }}'
- name: Add all instance public IPs to host group
add_host:
hostname: '{{ private_ip }}'
groups: ec2_hosts
loop: '{{ ec2_result.instances }}'
The error
TASK [Wait for SSH to come up] ******************************************************************************************************************************
task path: /home/user1/create_awsVM.yml:61
fatal: [localhost]: FAILED! => {
"msg": "The task includes an option with an undefined variable. The error was: 'private_ip' is undefined\n\nThe error appears to be in '/home/user1/create_awsVM.yml': line 61, column 7, but may\nbe elsewhere in the file depending on the exact syntax problem.\n\nThe offending line appears to be:\n\n\n - name: Wait for SSH to come up\n ^ here\n"
}
PLAY RECAP **************************************************************************************************************************************************
localhost : ok=5 changed=1 unreachable=0 failed=1 skipped=0 rescued=0 ignored=0
What I also tried:
- name: Wait for SSH to come up
wait_for:
host: '{{ item.private_ip }}'
port: 22
delay: 60
timeout: 320
state: started
loop: '{{ ec2_result.instances }}'
I used item as item.private_ip as thought it might work with loop but no luck.
Any help will be much appreciated.
