Volume 6: Production Best Practices, Performance & Troubleshooting¶

Who This Volume Is For¶

Engineers and teams running Ansible against real production infrastructure — hardening it, scaling it to hundreds or thousands of hosts, automating Windows fleets alongside Linux, and diagnosing failures quickly instead of guessing.

Prerequisites¶

Volume 2: Playbooks, Roles & Collections and Volume 3: Core Internals & Python Architecture — performance tuning and troubleshooting both depend on understanding what's actually happening internally.

Chapters¶

1. Security — Vault, secrets, SSH keys, become, least privilege, credential management, and sensitive logging
2. Performance and Scaling — forks, SSH multiplexing, pipelining, fact caching, async/poll, strategy plugins, Mitogen's history, and scaling to 10,000 hosts
3. Windows Automation — WinRM, PowerShell, pywinrm, Windows modules, and Kerberos/NTLM/CredSSP authentication
4. Troubleshooting — interpreter errors, permission denied, SSH issues, YAML syntax, undefined variables, and troubleshooting flowcharts
5. Best Practices — naming, repository layout, Git workflow, CI, and versioning
6. Real Production Projects — LAMP deployment, Kubernetes bootstrap, Docker installation, patch management, and cloud provisioning

What You Will Be Able to Do After This Volume¶

• Run Ansible securely against production credentials and secrets without leaking them into logs or version control
• Tune Ansible to run efficiently against fleets from dozens to thousands of hosts
• Automate Windows hosts alongside Linux with the correct authentication method for your environment
• Diagnose a failing playbook systematically instead of by trial and error
• Structure a production Ansible repository the way experienced teams actually do
