feat: add cron scheduling support for one-shot compose services#97
Merged
Conversation
Add a `docker-orchestrate cron` command that runs as a long-lived daemon, scheduling one-shot Compose services based on `x-cron` configuration with structured webhook notifications and multi-project support. New commands: - `cron` -- all-in-one scheduler + spawner + notifier - `cron run` -- scheduler/spawner only - `cron notify` -- notifier only (watches Docker events) - `cron install` -- generates systemd/runit service configs - `cron uninstall` -- removes installed service configs Key features: - Service-level `x-cron` extension with schedule, timezone, timeout, no-overlap, and notify configuration - Project-level `x-cron-defaults` for shared settings - Fire-and-forget container spawning with metadata labels - Durable notifications via container labels (survives restarts) - Multi-project directory scanning with .docker-orchestrate file support - Midnight-pinned @every intervals (stable across restarts) - Timezone resolution: per-service > project defaults > CLI > system - Config hot-reload via periodic re-read and SIGHUP signal - Overlap prevention via running container detection - Orphan container recovery on startup - Deploy/cron mutual exclusivity (x-cron services skipped during deploy)
- Remove duplicate #### Flags and #### Examples headings in command-reference.md - Add language specifier to bare fenced code blocks in cron-scheduling.md - Add blank lines before lists per MD032 rule
