Rallly on Cloud Run — Lab Guide
Overview
Estimated time: 45–90 minutes
Rallly is an open-source, self-hosted meeting-scheduling and group-poll application — a privacy-friendly alternative to Doodle — built with Next.js and Prisma. This lab takes you through the full operational lifecycle of the Rallly on Cloud Run module on Google Cloud: deploy it, access and verify it, run it day-to-day, observe it, diagnose common problems, and tear it down.
The lab focuses on operating the Cloud Run module and the Google Cloud platform, not on Rallly product features. For the complete list of provisioned services and every configuration input (organised by group), see the Configuration Guide — this lab deliberately does not duplicate that detail so it stays accurate over time.
Objectives
By the end of this lab you will be able to:
- Deploy the module from the RAD platform and locate the resources it provisions.
- Access and verify the running service.
- Perform day-2 operations — inspect, scale, update, and manage secrets and SMTP settings.
- Observe the service with Cloud Logging and Cloud Monitoring.
- Diagnose and resolve the most common deployment and runtime issues.
- Tear the deployment down cleanly.
Prerequisites
- Services_GCP deployed in the target project (provides the VPC, Cloud SQL, Artifact Registry, and shared service accounts this module depends on).
- A Google Cloud project with billing enabled.
- gcloud CLI authenticated:
gcloud auth loginandgcloud auth application-default login. - Project Owner (or equivalent) IAM on the project.
- RAD platform access with permission to deploy modules into the project.
Set these shell variables once; every task below reuses them:
export PROJECT="<your-gcp-project-id>"
export REGION="us-central1" # the region you deploy into
Task 1 — Deploy the module [Automated]
-
In the RAD platform, open Rallly (Cloud Run), set
project_id, and review the inputs. Configure only what you need — the Configuration Guide documents every input by group, with defaults. If you already have an SMTP relay, setsmtp_userandsmtp_passwordnow (the defaultsmtp_hostissmtp.gmail.com) so email login works from the first boot. Review the estimated cost (if credits are enabled) and click Deploy, which opens the deployment status page with real-time logs. -
The platform provisions the Cloud Run service, a Cloud SQL (PostgreSQL 15) database with its Secret Manager secrets (
SECRET_PASSWORD,NEXTAUTH_SECRET, an optionalSMTP_PWD, and the database password), builds the container image, and runs a one-shot database-initialisation job that creates the empty database and role. First deploys take roughly 15–25 minutes (Cloud SQL creation dominates). -
When it completes, discover the resources with name-agnostic filters (so the commands keep working regardless of the deployment suffix):
SERVICE=$(gcloud run services list --project="$PROJECT" --region="$REGION" \
--filter="metadata.name~rallly" --format="value(metadata.name)" --limit=1)
SERVICE_URL=$(gcloud run services describe "$SERVICE" \
--project="$PROJECT" --region="$REGION" --format="value(status.url)")
echo "Service: $SERVICE"
echo "URL: $SERVICE_URL"
Task 2 — Access & verify [Manual]
-
Confirm the service is fully ready — database migrated and reachable. Rallly's own status endpoint only returns 2xx once the app has finished the first-boot Prisma migration and confirmed its dependencies (this is a stricter check than the platform's own TCP startup probe, which only confirms the port is bound):
curl -s -o /dev/null -w '%{http_code}\n' "$SERVICE_URL/api/status" # expect 200 -
Open
$SERVICE_URLin a browser. Rallly's login is passwordless and email-based — there is no pre-seeded admin account. Enter your email on the sign-in page; Rallly emails a verification link/code through the configured SMTP relay. If nothing arrives, confirm SMTP is actually configured (Task 3, step 4) before assuming the deployment is broken. -
If you plan to front the service with a custom domain, set
base_urlto that domain and apply via Update so invite and login links resolve to the address users actually visit, rather than the rawrun.appURL.
Task 3 — Operate & keep it running (Day-2) [Manual]
-
Inspect the service and its revisions (each deploy creates an immutable revision; traffic shifts to the newest healthy one):
gcloud run services describe "$SERVICE" --project="$PROJECT" --region="$REGION"
gcloud run revisions list --service="$SERVICE" --project="$PROJECT" --region="$REGION" -
Scale by changing the min/max instance inputs and clicking Update on the deployment details page — the module owns the service spec, so scaling is a configuration change, not a manual
gcloudedit (a manual edit would be reverted on the next apply). Rallly keeps all state in PostgreSQL, so it scales horizontally without any shared cache or filesystem. -
Update the application version by changing the version input in the RAD platform and applying it via Update; a new image builds and a new revision rolls out. Rallly's own
./docker-start.shrunsprisma migrate deployon every boot, so schema migrations apply automatically — no separate migration step is required. -
Manage secrets and SMTP:
gcloud secrets list --project="$PROJECT" --filter="name~rallly"
gcloud run services describe "$SERVICE" --region="$REGION" \
--format='value(spec.template.spec.containers[0].env)' # confirm SMTP_* / base URL envNever rotate
SECRET_PASSWORDorNEXTAUTH_SECREToutside of a planned maintenance window — see Task 5. -
Open a database session for inspection or maintenance:
INSTANCE=$(gcloud sql instances list --project="$PROJECT" --format="value(name)" --limit=1)
gcloud sql connect "$INSTANCE" --user=rallly --project="$PROJECT"
Task 4 — Observe: Logging & Monitoring [Manual]
-
Logs — from the CLI or the Logs Explorer:
gcloud run services logs read "$SERVICE" --project="$PROJECT" --region="$REGION" --limit=50Logs Explorer filter:
resource.type="cloud_run_revision" AND resource.labels.service_name="<service>". -
Monitoring — open the Cloud Run dashboard for the service and review request count, request latency (P50/P95/P99), instance count (scaling behaviour), and CPU / memory utilisation. The module can provision an uptime check; confirm it is green under Monitoring → Uptime checks, and review Alerting → Policies.
Task 5 — Troubleshoot & debug [Manual]
Durable techniques for the failure modes you are most likely to hit. These are platform-level diagnostics and do not change with Rallly releases.
- Revision unhealthy / service won't serve: inspect the latest revision and its
logs for startup errors, and confirm env vars and secrets resolved. The startup
probe is TCP by design (not
/api/status, which only returns 2xx at full application readiness) and allows roughly 230 seconds of budget (30s initial delay- 10 retries at 20s) to cover the first-boot Prisma migration.
gcloud run revisions list --service="$SERVICE" --project="$PROJECT" --region="$REGION"
gcloud run services logs read "$SERVICE" --project="$PROJECT" --region="$REGION" --limit=100 - Users cannot sign in: Rallly's login is passwordless and email-based. Confirm
smtp_user/smtp_passwordare set (defaultsmtp_host = smtp.gmail.comis not enough on its own) and check the running revision's env vars forSMTP_*. - Database connection errors: confirm the Cloud SQL instance is
RUNNABLE, the DB password secret exists, and the initialisation job completed successfully. - Initialisation job failed: list executions and read the failed one's logs:
gcloud run jobs executions list --job="${SERVICE}-db-init" \
--project="$PROJECT" --region="$REGION" - Invite/login links point at the wrong host: set
base_urlto your custom domain — otherwiseNEXT_PUBLIC_BASE_URL/NEXTAUTH_URLdefault to the rawrun.appURL. - Image build failed: review Cloud Build history for the failed build's log.
- 403 / permission errors: verify the runtime service account's IAM roles.
See the Configuration Guide's Configuration Pitfalls section for setting-specific
gotchas (including the critical rule never to rotate SECRET_PASSWORD or
NEXTAUTH_SECRET after first boot, and the db_name/db_user immutability rule).
Task 6 — Tear down [Automated]
On the Deployments page, open the deployment and click the Trash icon (Delete). Delete runs terraform destroy and is irreversible (the deployment record is retained for history). If a deployment is stuck and the RAD platform can no longer manage it (for example after manual changes that conflict with the Terraform state), use Purge instead — it removes the deployment from RAD's records without destroying the cloud resources (it makes RAD forget the project). This removes everything the module created — the Cloud Run service,
Cloud SQL database, Secret Manager secrets, and Artifact Registry images. Resources
owned by Services_GCP (the VPC, shared Cloud SQL, registry) are managed
separately and are not removed here.
