Dynamic inventory not working in playbook

[Pavanan M S]

Hi all,

         I am using a playbook to create a GCE VM intance and deploy some code to it. I was hard coding the IP of the created instance until i realized the use of dynamic inventories. 

I downloaded gce.py and made it executable. Commands like 

./gce.py --list 

GCE_INI_PATH=/home/pavanan/Documents/ansible_backp/messaging-deploy/gce.ini ansible all -m ping

are working as expected. 

I have two playbooks. One creates an instance in localhost and adds it to a group using add host command, like the following playbook from google cloud platform guide 

- name: Create instance(s)
  hosts: localhost
  gather_facts: no
  connection: local

  vars:
    machine_type: n1-standard-1 # default
    image: debian-7
    service_account_email: uniq...@developer.gserviceaccount.com
    pem_file: /path/to/project.pem
    project_id: project-id

  tasks:
    - name: Launch instances
      gce:
          instance_names: dev
          machine_type: "{{ machine_type }}"
          image: "{{ image }}"
          service_account_email: "{{ service_account_email }}"
          pem_file: "{{ pem_file }}"
          project_id: "{{ project_id }}"
          tags: webserver
      register: gce

    - name: Wait for SSH to come up
      wait_for: host={{ item.public_ip }} port=22 delay=10 timeout=60
      with_items: gce.instance_data

    - name: Add host to groupname
      add_host: hostname={{ item.public_ip }} groupname=gce-instances
      with_items: gce.instance_data

And the other playbook has host as gce-instances and the other deployment steps.

I made an inventory directory and placed my hosts file, with just [local]  and localhost in it, and also the file gce.py.

How can I connect to and do the operations on the instance created above? 

I tried,

$ export GCE_INI_PATH=/home/pavanan/Documents/ansible_backp/messaging-deploy/gce.ini

$ ansible-playbook  -i  inventory/gce.py  my_playbook.yml
