Deploy Subnets into Different availability zones using Ansible.

[Bhotu]

I am Working on putting subnets into different availability zones with the help of ansible. I want to put subnet1 into us-east-1a, then subnet2 into us-east-1b and so on. Currently I can only be able to put servers onto us-east-1a only. Here is the ansible scripts. 

---
- name: Create AWS VPC and Subnets
  hosts: localhost
  connection: local
  gather_facts: false
  vars:
      region: us-east-1
      prefix: mahela_ansible
      az1: us-east-1a
      az2: us-east-1b
      az3: us-east-1c
 tasks:
 - name: Create VPC
   local_action:
     module: ec2_vpc
     region: "{{ region }}"
     cidr_block: 10.123.0.0/16
     resource_tags: '{"Name":"{{ prefix }}"}'
     subnets:
      - name: Cassandra Subnet
        cidr: 10.123.0.0/24
        az: "{{ az1 }}"
        resource_tags: '{"Name":"{{ prefix }}_cassandra"}'

      - name: MongoDB Subnet
        cidr: 10.123.1.0/24
        az: "{{ az2 }}"
        resource_tags: '{"Name":"{{ prefix }}_Mongodb"}'

      - name: Elastic Search
        cidr: 10.123.2.0/24
        az: "{{ az3 }}"
        resource_tags: '{"Name":"{{ prefix }}_elasticsearch"}'

What happens when you try?

Hi I can only find all the subnets in the same availability zones which is us-east-1a only. I want each of my subnets into different availability zones in AWS.

Hmm, I don't have any other great ideas, then -- setting the 'az'
parameter in the elements of the 'subnets' list does the right thing when
I try it. (I haven't tried your exact example, but something similar when
I set up a VPC at AWS a while ago.) I did encounter an error where AWS
wouldn't let me create a subnet in a particular AZ (us-east-1c, I think),
but that gave an obvious error, it didn't just drop the subnet into a
different AZ.

Can you try to use this technique on line#26

For complete reference, check the webserver creation playbook as well.
