Claude Code

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

curl

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

Bash

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

rsync

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

Cron

Cron and crontab reference — schedule syntax, special strings, per-deploy crontab management, flock locks, log capture, and systemd timer alternatives.

jq

jq reference for deploy pipelines — parsing GitHub/GitLab webhooks, extracting commit SHAs, filtering CI logs, and using --exit-status as a deploy gate.

Git

Git command reference for deployments — branching strategy, tag-based releases, git archive for clean artifacts, force-push safety, and recovery.

systemd

systemd reference for production servers — systemctl, journalctl, unit-file hardening, timers, and integration into deploy hooks.

PostgreSQL
