Cheatsheets

Quick-reference docs for the tools and workflows that matter most when shipping code.

Containers

Docker, Compose, Kubernetes — quick refs for shipping containers.

Essential Docker commands for shipping web apps — containers, images, multi-stage builds, Compose, and deployment patterns that survive production.

Git, CI, shell, ops tools.

Essential SSH commands for servers, keys, tunnels, and deploys — including deploy-key patterns, ssh-agent forwarding, and key-rotation playbooks.

Claude Code commands, hooks, and MCP setup with deployment recipes — Dockerfile generation, CI debugging, SSH config drafting, rollback plans.

Essential curl commands for HTTP requests, deploy webhooks, post-deploy smoke tests, healthcheck loops, and `--fail` discipline in CI pipelines.

Bash scripting reference for deploy hooks — variables, conditionals, arrays, traps, `set -euo pipefail`, lockfiles, and idempotent file ops.

rsync reference for deploy workflows — atomic releases, exclude patterns, `--delete` safety, restartable transfers over SSH, and bandwidth caps.
