Ansible Inventory Plugin

Intro

This repo is a smaller part to executing generic ansible commands inside an ansible execution environment using ansible-runner to consume inventory from an external source other than an inventory file.

Here is the repo that is used inside an execution env for those who are curious: https://github.com/cloudguruab/edpm_plugin

If you have questions feel free to open an issue.

Requirements & Dependencies

I have specified all the requirements for this plugin here

  • Ansible
pip install ansible
Enter fullscreen mode Exit fullscreen mode
  • AWS CLI
pip install boto3
pip install awscli
Enter fullscreen mode Exit fullscreen mode

Setup

Be sure the desired collection is installed if you're pulling from pre-built module

ansible-galaxy collection list # list installed plugins
ansible-galaxy collection install amazon.aws
Enter fullscreen mode Exit fullscreen mode

After running ansible-galaxy collection list you should see something like this:

Collection        Version
----------------- -------
amazon.aws        5.1.0
community.general 5.2.0
openstack.cloud   1.10.0
Enter fullscreen mode Exit fullscreen mode

Once this is done you need to navigate to your aws console and obtain your aws_secret_key, and aws_public_key:

#setting up auth 
bash-5.1$ aws configure
AWS Access Key ID [None]: key
AWS Secret Access Key [None]: key
Default region name [None]: us-east-1
Default output format [None]: json
Enter fullscreen mode Exit fullscreen mode

Updating your project

We need to update our inventory source with our private_ip to connect with our instance. Our ansible config file will also map to our inventory source and the plugin we are using.

  • aws_ec2.yml:
plugin: aws_ec2
regions:
  - us-east-1
keyed_groups:
  - key: tags.Tagname
filters:
  instance-state-name: running
compose:
  ansible_host: private_ip
Enter fullscreen mode Exit fullscreen mode
  • ansible.cfg:
[defaults]
enable_plugins=aws_ec2
inventory=aws_ec2.yml
Enter fullscreen mode Exit fullscreen mode

Testing

Lets look for our host:

ansible-inventory -i aws_ec2.yml --list #look for host
ansible-inventory -i aws_ec2.yml --graph # graph view
Enter fullscreen mode Exit fullscreen mode
