Ansible Collection: turbonomic_eda

This IBM Turbonomic Ansible Collection provides examples that can be used to automate Turbonomic cloud scaling decisions using Event Driven Ansible (EDA). Users are able to quickly realize the value of Turbonomic Hybrid Cloud optimization decisions by leveraging the flexible and powerful automation capabilities of Event Driven Ansible.

Included in the Collection

• Module to create a webhook workflow within your Turbonomic Instance for use in Automation Policies
• Role for resizing an AWS EC2 instance via the Ansible module amazon.aws.ec2_instance and aws cli
• Role for resizing an Azure Virtual Machine via the Ansible module azure.azcollection.azure_rm_virtualmachine
• Playbooks for Event Driven Ansible to call to execute the roles
• Sample Event Driven Ansible Rulebook

Prequisite

The following are required on the Event Driven Ansible Rulebook server in order to execute the playbooks and roles from this collection.

Install Necessary Ansible Collections

ansible-galaxy collection install ansible.eda azure.azcollection amazon.aws

Install Necessary Python Software

python3 -m pip install awscli

Installing the Collection

ansible-galaxy collection install ibm.turbonomic_eda

Creating the webhook in Turbonomic

The Collection contains roles and playbooks to be used with Event Driven Ansible (EDA). Turbonomic cloud scaling automation policies can be configured to use a webhook workflow to send actions to EDA.

The webhook workflow feature must be enabled in Turbonomic using the steps described here to add and enable a webhook probe.

Below is a example of a Ansible task to create the webhook workflow in Turbonomic:

- name: Add My Webhook with verify and eda port
  ibm.turbonomic_eda.eda_webhook:
    connection: turbonomic.example.com
    username: administrator
    password: password
    verify: false
    eda_server: eda.example.com
    eda_port: 5000

• connection -> Hostname/IP of your Turbonomic instance
• username -> Turbonomic account with administrator access to create the webhook
• password -> Password of Turbonomic account
• verify -> Whether or not to validate the TLS certificate for the Turbonomic hostname
• eda_server -> Hostname/IP of your EDA server
• eda_port -> Port EDA server is listening on

Once the webhook is created, it must be assigned to cloud scaling actions that are to be forwarded to the EDA server using a Turbonomic automation policy. Please see Turbonomic documentation for further details on how to create automation policies. The webhook workflow should be selected for the Automation and Orchestration, Action Execution stage to replace the native execution for the entities in the scope of the policy.

Today the collection only supports scaling of AWS EC2 and Azure Virtual Machines which are known as Cloud Scaling Actions in Turbonomic.

Using the Collection in an Event Driven Ansible Rulebook

Once the webhook is created and configured in Turbonomic to send the action(s) to EDA, you can use the turbonomic_actions rulebook to call the Ansible playbooks and roles to execute the Cloud Scaling Actions.
