🛠️Ansible

NEW

An IT automation platform for configuration management, orchestration, and deployment using declarative playbooks.

DESCRIPTION

Ansible is an open source automation tool that uses agentless connections (typically SSH) to configure systems, deploy applications, and orchestrate workflows. Playbooks written in YAML declare desired states, ensuring idempotent changes via modules. Its simplicity, extensive module ecosystem, and inventory model enable scalable automation across on-prem and cloud environments. Ansible Tower/AWX adds RBAC, scheduling, and UI/API for enterprise use. It integrates with CI/CD pipelines for repeatable infrastructure and application delivery.

TOP QUESTIONS

Why choose Ansible for automation?

It is agentless, simple to learn with YAML, and has a large module ecosystem, reducing operational overhead and accelerating automation.

Category: Relevancy

What are Ansible playbooks?

They are YAML files that declare desired states and tasks, executed idempotently across inventories of hosts.

Category: Definition

How does Ansible differ from Terraform?

Ansible focuses on configuration and orchestration; Terraform focuses on provisioning cloud resources declaratively.

Category: Comparison

What is Ansible Tower/AWX?

It’s the enterprise UI/API layer adding RBAC, workflows, scheduling, and auditing to Ansible automation.

Category: Tooling

What is a common mistake when writing playbooks?

Not ensuring idempotency can cause drift and repeated changes; prefer stateful modules and proper checks.

Category: Mistakes

How does Ansible integrate with CI/CD?

Playbooks run in pipeline stages for environment provisioning, configuration, and application deployment, ensuring repeatability.

Category: Integration

What are Ansible inventories?

They define groups and hosts to target, sourced from static files or dynamic inventory scripts for clouds.

Category: Concept

How is security handled in Ansible?

Use Ansible Vault for secrets, least privilege SSH, and RBAC in Tower/AWX to control access.

Category: Security

What are Ansible collections?

Collections package modules, plugins, and roles for reuse and distribution via Ansible Galaxy or private registries.
