This guide provides a comprehensive overview of Ansible basics, focusing on best practices and common pitfalls to avoid when deploying infrastructure as code. Here are some key takeaways:
-
Never use
state: latestfor packages facing external integrations: This is crucial to prevent unexpected changes that could break production systems. -
Use version pinning: Always specify exact versions or ranges (e.g.,
1.24.*) instead of relying onlatest. -
Run with
--check --diffbefore production: This ensures you understand exactly what will change without actually making any changes. -
Handlers run once per playbook execution: Understand this behavior to avoid redundant service restarts.
-
Build idempotency deliberately: Don't assume Ansible automatically makes your playbooks idempotent; design tasks carefully.
-
Use
changed_whenandfailed_whenwisely: These directives can make your playbooks more reliable in CI/CD pipelines. -
Deep dive into troubleshooting: The guide provides diagnostic commands for production issues.
-
Ansible vs Terraform comparison: Understand when to use each tool based on project requirements.
