Ansible Automation Ansible Tower and AWX 3

Question 1

How do you install AWX on Kubernetes using the official deployment method?

Accepted Answer

Deploy the AWX Operator using kubectl, then create an AWX custom resource definition (CRD) to provision the AWX instance

Answer

The AWX Operator (a Kubernetes operator) is the official and recommended deployment method for AWX on Kubernetes clusters.

Question 2

What is the purpose of 'schedules' in Ansible Tower/AWX?

Accepted Answer

They automate job launches at specified times using cron-like syntax, enabling unattended recurring automation

Answer

Schedules enable time-based automation—running playbooks automatically at defined intervals without human intervention.

Question 3

What is the 'callback URL' (Provisioning Callback) feature in Ansible Tower?

Accepted Answer

A feature that allows newly provisioned hosts to call Tower and trigger a Job Template to configure themselves, enabling auto-provisioning workflows

Answer

Provisioning callbacks allow hosts to initiate their own configuration by calling Tower's API, enabling push-based provisioning from cloud init or user-data scripts.

Question 4

In Ansible Tower/AWX, what is 'fact caching' and how does it benefit automation at scale?

Accepted Answer

Tower stores Ansible facts from previous runs in its database, enabling playbooks to use cached facts without running the setup module on every execution

Answer

Fact caching eliminates repeated setup module runs, significantly reducing playbook execution time for large inventories.

Question 5

What does the 'ask_variables_on_launch' setting on a Tower Job Template enable?

Accepted Answer

It allows operators launching the job to provide extra variables at launch time through the UI or API without a survey

Answer

Enabling 'ask_variables_on_launch' presents a text box in the Tower UI where operators can provide ad-hoc extra variables in YAML/JSON format at launch time.
