Ansible dynamic inventory when connecting with AWS - amazon-web-services

Question

I have downloaded ec2.py and ec2.ini files and placed them under
/etc/ansible/inventory
and i have changed the ansible.cfg to
inventory = /etc/ansible/inventory/ec2.py
i have environment variables set up as
export AWS_ACCESS_KEY_ID="XXXXXXXXXXXXXXX"
export AWS_SECRET_ACCESS_KEY="XXXXXXXXXXXXXXXXXXXXX"
export AWS_DEFAULT_REGION="us-east-1"
export EC2_INI_PATH="/etc/ansible/inventory/ec2.ini"
now when i run ansible -m ping all
i am getting
[WARNING]: provided hosts list is empty, only localhost is available
instead of pinging all instances in my account
when i run ./ec2.py --list i get
{
"_meta": {
"hostvars": {}
}
}
all my instances in aws are running

Answer 1

It seems you are not using the right inventory file.
Check ec2.py is executable (chmod +x)
Run ansible with -v option to check what config file it is really
using
ansible -v -m ping all
Check if you have ANSIBLE_INVENTORY or ANSIBLE_HOSTS environment
variables overriding expected config file. You can override inventory definition by setting
export ANSIBLE_INVENTORY=/etc/ansible/inventory/ec2.py
Remind that configuration files are processed in the following order
ANSIBLE_CONFIG (an environment variable)
ansible.cfg (in the current directory)
.ansible.cfg (in the home directory)
/etc/ansible/ansible.cfg
Prior to 1.5 the order was:
ansible.cfg (in the current directory)
ANSIBLE_CONFIG (an environment variable)
.ansible.cfg (in the home directory)
/etc/ansible/ansible.cfg
