Compare JSON and YAML configuration files programmatically — catch config drift after deployments, verify running state against expected, and surface exactly what changed. https://python.bradpenney.io/day_one/comparing_configs/ Mon, 11 May 2026 21:23:00 -0300 Exploring Python https://python.bradpenney.io/day_one/comparing_configs/ Is It Still Up? Write a Python health-check poller that distinguishes connection errors from HTTP errors, handles timeouts, and exits cleanly for use in deployment pipelines. https://python.bradpenney.io/day_one/health_check/ Mon, 11 May 2026 21:23:00 -0300 Exploring Python https://python.bradpenney.io/day_one/health_check/ Overview Python automation for platform engineers who know bash — task-first guides for health checking, log parsing, config comparison, and fleet operations. https://python.bradpenney.io/day_one/overview/ Mon, 11 May 2026 21:23:00 -0300 Exploring Python https://python.bradpenney.io/day_one/overview/ What Just Broke? Use Python to parse application log files — count errors by component, find when errors started, and understand failure patterns that grep alone can't surface. https://python.bradpenney.io/day_one/parsing_logs/ Mon, 11 May 2026 21:23:00 -0300 Exploring Python https://python.bradpenney.io/day_one/parsing_logs/ Run This Everywhere Loop over a server inventory in Python, run checks across your fleet, collect per-server results, and produce a clear pass/fail report — with proper failure handling. https://python.bradpenney.io/day_one/run_everywhere/ Mon, 11 May 2026 21:23:00 -0300 Exploring Python https://python.bradpenney.io/day_one/run_everywhere/ The "Don't Do This" Guide Production safety rules for Python automation — no hardcoded credentials, no shell injection, always build dry-run first, and never let exceptions fail silently. https://python.bradpenney.io/day_one/safety_guide/ Mon, 11 May 2026 21:23:00 -0300 Exploring Python https://python.bradpenney.io/day_one/safety_guide/ Why Python (Not Just Bash) A practical decision framework for platform engineers: when to stay in bash, when to switch to Python, and what the real differences look like in practice. https://python.bradpenney.io/day_one/why_python/ Mon, 11 May 2026 21:23:00 -0300 Exploring Python https://python.bradpenney.io/day_one/why_python/ My Bash Script Is Getting Out of Hand Migrate an unwieldy bash deployment script to Python using subprocess — keep running shell commands while gaining proper error handling, logging, and readable control flow. https://python.bradpenney.io/day_one/wrapping_bash/ Mon, 11 May 2026 21:23:00 -0300 Exploring Python https://python.bradpenney.io/day_one/wrapping_bash/ Environment Variables and Secrets Load API keys, passwords, and tokens in Python automation scripts using environment variables, .env files, and secrets stores — without hardcoding anything. https://python.bradpenney.io/essentials/env_and_secrets/ Mon, 11 May 2026 21:23:00 -0300 Exploring Python https://python.bradpenney.io/essentials/env_and_secrets/ Working with YAML Read, modify, and generate Kubernetes manifests and other YAML files in Python using PyYAML — including multi-document YAML, safe loading, and common pitfalls. https://python.bradpenney.io/essentials/yaml/ Mon, 11 May 2026 21:23:00 -0300 Exploring Python https://python.bradpenney.io/essentials/yaml/ Home Python automation for platform engineers and SREs — task-first guides for health checking, log parsing, config comparison, fleet operations, and more. https://python.bradpenney.io/ Wed, 04 Jun 2025 10:14:00 -0300 Exploring Python https://python.bradpenney.io/
