fix(ci): migrate 3 monitoring crons to self-hosted runners (DAK-7665) - #257
Merged
Conversation
Move Hetzner Health Check, Wedged Runner Auto-Heal, and Playground Uptime Check off ubuntu-latest (GitHub-hosted) onto self-hosted Hetzner runners so monitoring survives GitHub Actions billing outages (DAK-7664). - hetzner-health-check.yml: both jobs → [self-hosted, linux, arm64] (monitors prod server 178.104.45.161, no self-reference risk) - playground-uptime-check.yml → [self-hosted, linux, arm64] (HTTP probe only, no self-reference risk) - runner-wedged-watchdog.yml → [self-hosted, linux, x64] (runs on x64 to monitor ARM cross-coverage; x64-watches-ARM is the common failure direction; updated comment documents partial trade-off) Partial self-reference accepted per DAK-7665: coverage on self-hosted beats zero coverage during a GitHub billing lock.

… (DAK-7665) The 'Validate Docker Configs' CI job was on ubuntu-latest solely because hadolint-action needs Docker auth to pull ghcr.io/hadolint/hadolint. This caused CI to fail entirely during the 2026-08-01 GitHub billing lock (DAK-7664). Fix: run on [self-hosted, linux, arm64] + explicit docker/login-action@v4 step to authenticate Docker on the runner to GHCR using GITHUB_TOKEN (packages: read). Docker and docker compose are both available on the ARM runner (Docker 29.1.3, Compose v5.1.1 verified 2026-08-01). Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

Summary
Migrates the 3 GitHub-hosted (ubuntu-latest) monitoring cron workflows to self-hosted Hetzner runners so infra monitoring survives GitHub Actions billing outages (DAK-7664 incident, 2026-08-01 ~17:31Z).
Workflows changed:
[self-hosted, linux, arm64](both jobs)178.104.45.161via HTTP + Hetzner API. No self-reference risk.[self-hosted, linux, arm64]playground.dakera.ai. No self-reference risk.[self-hosted, linux, x64]Verification:
