Concelier Alpine SecDB Connector - Operations Runbook

Last updated: 2025-12-22

1. Overview

The Alpine connector pulls JSON secdb feeds (main/community) for configured releases and maps CVE identifiers to APK version ranges. It preserves native APK versions and emits rangeKind: apk so downstream consumers keep distro semantics intact.

2. Configuration knobs (`concelier.yaml`)

concelier:
  sources:
    alpine:
      baseUri: "https://secdb.alpinelinux.org/"
      releases:
        - "v3.18"
        - "v3.19"
        - "v3.20"
      repositories:
        - "main"
        - "community"
      maxDocumentsPerFetch: 20
      fetchTimeout: "00:00:45"
      requestDelay: "00:00:00"
      userAgent: "StellaOps.Concelier.Alpine/0.1 (+https://stella-ops.org)"

Recommendations

Keep releases to supported Alpine branches only; avoid stale branches in production unless you maintain a mirror.
Use requestDelay when running multiple source connectors on shared egress.

3. Default job schedule

Job kind	Cron	Timeout	Lease
`source:alpine:fetch`	`/30 * * *`	5 minutes	4 minutes
`source:alpine:parse`	`7,37 * * * *`	6 minutes	4 minutes
`source:alpine:map`	`12,42 * * * *`	8 minutes	4 minutes

The cadence staggers fetch, parse, and map so each stage has a clean window to complete. Override via concelier.jobs.definitions[...] when coordinating multiple sources on the same scheduler.

4. Offline and air-gapped deployments

Mirror secdb JSON files into a local repository and point baseUri to the mirror host.
The connector allowlists only the baseUri host; update it to match the internal mirror host.
Keep fixtures and exported bundles deterministic by leaving the order of releases and repositories stable.
