I am using ec2.py dynamic inventory for provisioning with ansible. I have placed the ec2.py in /etc/ansible/hosts file and marked it executable. I also have the ec2.ini file in /etc/ansible/hosts.

> [ec2]
> 
> regions = us-west-2 regions\_exclude = us-gov-west-1,cn-north-1
> 
> destination\_variable = public\_dns\_name
> 
> vpc\_destination\_variable = ip\_address route53 = False
> 
> all\_instances = True all\_rds\_instances = False
> 
> cache\_path = ~/.ansible/tmp
> 
> cache\_max\_age = 0
> 
> nested\_groups = False group\_by\_instance\_id = True group\_by\_region = True group\_by\_availability\_zone = True group\_by\_ami\_id = True group\_by\_instance\_type = True group\_by\_key\_pair = True group\_by\_vpc\_id = True group\_by\_security\_group = True group\_by\_tag\_keys = True group\_by\_tag\_none = True group\_by\_route53\_names = True group\_by\_rds\_engine = True group\_by\_rds\_parameter\_group = True

Above is my ec2.ini file

```auto
---
- hosts: localhost
  connection: local
  gather_facts: yes
  vars_files:
   - ../group_vars/dev_vpc
   - ../group_vars/dev_sg
   - ../hosts_vars/ec2_info
  vars:
    instance_type: t2.micro
  tasks:
   - name: Provisioning EC2 instance
     local_action:
     module: ec2
     region: "{{ region }}"
     key_name: "{{ key }}"
     instance_type: "{{ instance_type }}"
     image: "{{ ami_id }}"
     wait: yes
     group_id: ["{{ sg_npm }}", "{{sg_ssh}}"]
     vpc_subnet_id: "{{ PublicSubnet }}"
     source_dest_check: false
     instance_tags: '{"Name": "EC2", "Environment": "Development"}'
 register: ec2
  - name: associate new EIP for the instance
    local_action:
      module: ec2_eip
      region: "{{ region }}"
      instance_id: "{{ item.id }}"
      with_items: ec2.instances
  - name: Waiting for NPM Server to come-up
    local_action:
      module: wait_for
      host: "{{ ec2 }}"
      state: started
      delay: 5
      timeout: 200
 - include: ec2-configure.yml

```

Now the configuring script is as follows

```auto
- name: Configure EC2 server
  hosts: tag_Name_EC2
  user: ec2-user
  sudo: True
  gather_facts: True
  tasks:
   - name: Install nodejs related packages
     yum: name={{ item }} enablerepo=epel state=present
     with_items:
      - nodejs
      - npm

```

However when the configure script is called, the second script results into no hosts found. If I execute the ec2-configure.yml just alone and if the EC2 server is up & running then it is able to find it and configure it.

I added the wait\_for to make sure that the instance is in running state before the ec2-configure.yml is called.

Would appreciate if anyone can point my error. Thanks

The inventory script is only invoked at the beginning of the playbook run.

You'll have to call your provisioning and configure playbooks separately,  
or use add\_host ([http://docs.ansible.com/add\_host\_module.html](http://docs.ansible.com/add_host_module.html)) to update  
the inventory in memory after you have provisioned a host.

Thank you for the reply Chris,  
I would appreciate if you can provide an example of how we can do the in-memory inventory update. Thank you
