- Docker compose: ping_group_range sysctl, without which ping monitors
silently report DOWN in containers
- README: data retention table (1000 checks / 5000 state changes per
monitor, 200 logs, pruned automatically), group-alert limitation note
- config-as-code: apply is not atomic + re-run convergence, backup
redaction footgun (/api/backup/export redacts by default), opsgenie
example (provider count was stale at 9), ntfy auth keys
Last upkeep-era name in the wire protocol. Breaking for mixed-version
clusters, but zero installed base exists pre-v0.1.0 — free now, breaking
forever after first tag.
No leader fencing exists — during a network partition both nodes run
checks and fire alerts independently. Document the behavior honestly:
duplicate alerts, doubled history, ~15s takeover, converges on heal.
Add declarative config-as-code support via YAML files. Monitors and
alerts can be exported, version controlled, and applied across instances.
- goupkeep export [-o file.yaml] dumps current state
- goupkeep apply -f file.yaml creates/updates to match desired state
- --dry-run shows planned changes without applying
- --prune deletes monitors/alerts not in the YAML
- Matching by name, alert references by name, nested group children
- CLI refactored to subcommands (apply, export, serve) with backward compat
- 24 tests covering apply, export, validation, round-trip idempotency
