🍹 The Update (preview) for dailydotdev/api/prod (at ae697a3) was successful.

✨ Neo Explanation

Routine deployment bumping all workloads to commit `574a2a57`, with fresh DB and ClickHouse migration jobs running against the new image. ✅ Low Risk

This is a standard application deployment rolling out a new build (574a2a57) to replace the previous one (26681605). All deployments and cron jobs are receiving only an image tag and version label update. The two migration Jobs (Postgres via TypeORM and ClickHouse) are being cycled by design — Pulumi names them with the commit SHA, so each deploy deletes the old job and creates a new one to run migrations against the new schema.

🔵 Info — The GCP provider warning about missing credentials is cosmetic for this Kubernetes-only update; it does not affect the apply.
