Hi Everyone, I am need of help to make it work in order to add the nat
instance id as gw for private subnet inside the routing table.
Here is my vpc playbook:
/tasks/vpc.yml
-----------------
---
- name: VPC | Creating an AWS VPC inside mentioned Region
local_action:
module: ec2_vpc
region: "{{ vpc_region }}"
state: present
cidr_block: "{{ vpc_cidr_block }}"
resource_tags: { "Name":"{{ vpc_name }}_vpc" }
subnets: "{{ vpc_subnets }}"
internet_gateway: yes
route_tables: "{{ public_subnet_rt }}"
=====
here is my vars/vpc.yml file:
---
ec2_inst_id: i-abc1432c
# Variables for VPC
vpc_name: tendo
vpc_region: ap-southeast-2
vpc_cidr_block: 172.25.0.0/16
public_cidr: 172.25.10.0/24
public_az: "{{ vpc_region}}b"
private_cidr: 172.25.20.0/24
private_az: "{{ vpc_region }}a"
nat_private_ip: 172.25.10.10
# Please don't change the variables below, until you know what you are doing
#
# Subnets Defination for VPC
vpc_subnets:
- cidr: "{{ public_cidr }}" # Public Subnet
az: "{{ public_az }}"
resource_tags: { "Name":"{{ vpc_name }}_public_subnet" }
- cidr: "{{ private_cidr }}" # Private Subnet
az: "{{ private_az }}"
resource_tags: { "Name":"{{ vpc_name }}_private_subnet" }
## Routing Table for Public Subnet
public_subnet_rt:
- subnets:
- "{{ public_cidr }}"
routes:
- dest: 0.0.0.0/0
gw: igw
When I run the above playbook it work fine:
ansible-playbook -i 'localhost,' --connection=local site.yml -vvvv 2 ↵

Here is the problem when I redefine the VPC with the nat-instance id as gw.
=========================================================
- name: NAT | NAT Route
set_fact:
private_subnet_rt: '{{ lookup("template",
"../templates/nat_routes.json.j2") }}'
- name: redefine vpc
local_action:
module: ec2_vpc
region: "{{ vpc_region }}"
state: present
cidr_block: "{{ vpc_cidr_block }}"
resource_tags: { "Name":"{{ vpc_name }}_vpc" }
subnets: "{{ vpc_subnets }}"
internet_gateway: yes
route_tables: "{{ private_subnet_rt }}"
Here are the content of the nat_routes.json.j2:
- subnets:
- {{ public_cidr }}
routes:
- dest: 0.0.0.0/0
gw: "igw"
- subnets:
- {{ private_cidr }}
routes:
- dest: 0.0.0.0/0
gw: {{ ec2_inst_id }}
I got this error when I run the above playbook after Creating the NAT
instance:
TASK: [redefine vpc]

Can you please point me that where I am making mistake.
Thanks
