NocoDB on Google Cloud Run
NocoDB is an open-source Airtable alternative that transforms any database into a smart spreadsheet with a no-code interface, REST and GraphQL APIs, and built-in automations. This module deploys NocoDB on Cloud Run v2 on top of the App_CloudRun foundation, which provisions and manages the shared Google Cloud infrastructure.
This guide focuses on the cloud services NocoDB uses and how to explore and operate them from the Google Cloud Console and the command line. For the mechanics common to every Cloud Run application — service identity, ingress and load balancing, scaling and concurrency, CI/CD, Cloud Armor, IAP, Binary Authorization, VPC Service Controls, backups, and the deployment lifecycle — refer to the App_CloudRun foundation guide rather than repeating them here.
1. Overview
NocoDB runs as a Node.js container on Cloud Run v2. The deployment wires together a focused set of Google Cloud services:
| Capability | Google Cloud service | Notes |
|---|---|---|
| Compute | Cloud Run v2 | Node.js service, 1 vCPU / 1 GiB by default, request-based autoscaling |
| Database | Cloud SQL for PostgreSQL 15 | Default engine; MySQL 8.0 also supported |
| Object storage | Cloud Storage | A dedicated uploads bucket for file attachments |
| Cache (optional) | Redis | Disabled by default; required when running multiple instances |
| Secrets | Secret Manager | Auto-generated JWT secret (NC_AUTH_JWT_SECRET) and database password |
| Ingress | Cloud Run URL / Cloud Load Balancing | Default run.app URL, optional external HTTPS load balancer + custom domain |
Sensible defaults worth knowing up front:
- PostgreSQL 15 is the default. MySQL 8.0 is also supported; set
database_typebefore first deploy. - NocoDB connects via private IP TCP, not the Auth Proxy socket. The Cloud SQL
Auth Proxy sidecar is disabled by default (
enable_cloudsql_volume = false) because NocoDB's internal URL constructor rejects Unix socket paths. The private IP is used directly. - NFS is disabled by default. NocoDB stores file attachments in Cloud Storage; a shared filesystem is not required.
- Redis is disabled by default. A single instance runs without Redis; enable it before scaling beyond one instance.
cpu_always_allocated = falseby default. Request-based billing; NocoDB's background automation and webhook retry logic only continues while an instance is handling a request. Settrue(withmin_instance_count ≥ 1) for uninterrupted background processing.- The JWT secret is generated automatically and stored in Secret Manager. Do not rotate it after the first deploy — all existing sessions and API tokens would be immediately invalidated.
- NocoDB handles its own database migrations on first start. No external init job is required.
- Health probes target
/api/v1/health, the dedicated health endpoint NocoDB exposes.
2. Google Cloud Services & How to Explore Them
All commands assume PROJECT and REGION are set. Service and resource names are
reported in the deployment Outputs.
A. Cloud Run — the NocoDB service
NocoDB runs as a Cloud Run v2 service that autoscales by request load between the minimum and maximum instance counts. Each deployment creates an immutable revision; traffic can be split across revisions for safe rollouts.
- Console: Cloud Run → select the service for revisions, traffic, logs, and metrics.
- CLI:
gcloud run services list --project "$PROJECT" --region "$REGION"
gcloud run services describe <service-name> --project "$PROJECT" --region "$REGION"
gcloud run revisions list --service <service-name> --project "$PROJECT" --region "$REGION"
See App_CloudRun for scaling, concurrency, execution environment, and traffic splitting.
B. Cloud SQL for PostgreSQL 15
NocoDB stores all application data (tables, views, automations, row data) in a managed Cloud SQL for PostgreSQL 15 instance. The service connects over a private IP TCP connection (no public IP, no Auth Proxy socket). On first deploy an initialization Job creates the application database and user; NocoDB then runs its own schema migrations on startup.
- Console: SQL → select the instance for connections, backups, flags, metrics.
- CLI:
gcloud sql instances list --project "$PROJECT"
gcloud sql instances describe <instance-name> --project "$PROJECT"
gcloud sql connect <instance-name> --user=<db-user> --project "$PROJECT"
The instance name, database, user, and password secret are in the Outputs. See App_CloudRun for the connection model, backups, and password rotation.
C. Cloud Storage — file uploads
NocoDB stores file attachments in a dedicated Cloud Storage bucket. The bucket
name is injected into the service as GCS_BUCKET_NAME automatically. The Cloud Run
service account is granted access by the foundation.
- Console: Cloud Storage → Buckets → select the uploads bucket.
- CLI:
gcloud storage buckets list --project "$PROJECT"
gcloud storage ls gs://<uploads-bucket>/ # bucket name is in the Outputs
See App_CloudRun for GCS Fuse, CMEK, and additional bucket options.
D. Redis cache (optional)
Redis backs NocoDB's caching layer and, in multi-instance deployments, keeps cache
and session state consistent. Redis is disabled by default; a redis_host must be
supplied when it is enabled.
- Console: Memorystore → Redis (if using a managed instance).
- CLI:
redis-cli -h <redis-host> ping
redis-cli -h <redis-host> info keyspace
E. Secret Manager
The NocoDB JWT secret (NC_AUTH_JWT_SECRET) and the database password are stored in
Secret Manager and injected into the service at runtime.
- Console: Security → Secret Manager.
- CLI:
gcloud secrets list --project "$PROJECT"
gcloud secrets versions access latest --secret=<secret-name> --project "$PROJECT"
See App_CloudRun for injection and rotation details.
F. Networking & ingress
The service is reachable at its run.app URL by default. An external HTTPS load
balancer with a custom domain, Cloud CDN, and Cloud Armor can be layered on; ingress
settings and VPC egress control connectivity.
- Console: Cloud Run (service URL); Network services → Load balancing.
- CLI:
gcloud run services describe <service-name> --region "$REGION" --format='value(status.url)'
gcloud compute addresses list --project "$PROJECT"
See App_CloudRun.
G. Cloud Logging & Monitoring
Container logs flow to Cloud Logging; Cloud Run and Cloud SQL metrics flow to Cloud
Monitoring, with optional uptime checks against /api/v1/health and alert policies.
- Console: Logging → Logs Explorer; Monitoring → Dashboards / Alerting.
- CLI:
gcloud run services logs read <service-name> --project "$PROJECT" --region "$REGION" --limit 50
3. NocoDB Application Behaviour
- First-deploy database setup. An initialization Job (
db-init) creates the NocoDB database and user before the service starts. It is idempotent. - Self-managed migrations. NocoDB runs its own database schema migrations on startup — there is no need to configure external migration jobs.
- JWT secret.
NC_AUTH_JWT_SECRETis generated automatically and stored in Secret Manager. Do not rotate it after the first deploy; all existing sessions and API tokens are immediately invalidated if the secret changes. - GCS uploads. The uploads bucket name (
GCS_BUCKET_NAME) is injected automatically. NocoDB stores all file attachments there. - NC_DB_ environment variables.* The custom Dockerfile in
NocoDB_Commonmaps the standardDB_*connection variables (injected by the foundation) to theNC_DB_*names NocoDB expects. Whencontainer_image_source = "prebuilt"the mapping is not applied — configureNC_DB_*variables manually viaenvironment_variables. - Public URL. The Cloud Run service URL is injected as
NC_PUBLIC_URLso NocoDB generates correct absolute URLs in share links, email notifications, and webhook callbacks. Controlled byservice_url_env_var_name(default"NC_PUBLIC_URL"). - Health path. Readiness and liveness probes target
/api/v1/health, which returns HTTP 200 when NocoDB is ready to accept requests. - Multi-instance sessions. With more than one instance and no Redis, NocoDB
cannot share session or cache state; users may be logged out when requests route to
a different instance. Enable Redis and set
redis_hostbefore scaling above one instance.

6. Configuration Pitfalls & Sensible Defaults
Risk: Critical (data loss / outage / security) — High (service degraded) — Medium (cost or partial degradation) — Low (minor).
| Setting | Sensible value | Risk | Consequence if wrong |
|---|---|---|---|
NC_AUTH_JWT_SECRET | auto-generated (immutable) | Critical | Rotating after first deploy immediately invalidates all sessions and API tokens. |
application_database_name / _user | set once | Critical | Immutable after first deploy; renaming recreates the DB/user and destroys data. |
enable_backup_import | false unless restoring | Critical | Enabling without a valid backup file fails the import job. |
enable_cloudsql_volume | false (default) | Critical | Setting true does not help NocoDB — its URL constructor rejects socket paths and all DB connections fail. |
memory_limit | 1Gi | High | NocoDB's Node.js process is OOM-killed below 512 Mi; production workloads with many automations need 2 Gi. |
enable_redis | true when >1 instance | High | Multiple instances without Redis cause session invalidation when requests route to different instances. |
redis_host | explicit when Redis on | High | A missing host causes all Redis connections to fail on startup. |
NC_PUBLIC_URL / service_url_env_var_name | NC_PUBLIC_URL (default) | High | NocoDB uses this to build share links, webhook URLs, and email notifications; an incorrect value breaks all outbound references. |
cpu_always_allocated | false (default); true for heavy automation | Medium | Under the default request-based billing, NocoDB background automation and webhook retry tasks pause between requests. |
min_instance_count | 1 | Medium | 0 causes cold starts during which webhook callbacks time out and are dropped. |
max_instance_count | keep low without Redis | Medium | Increasing above 1 without Redis causes session invalidation. |
enable_iap / enable_cloud_armor | enable for internal | Medium | NocoDB is otherwise publicly reachable at its run.app URL. |
application_version | pin to specific tag | Medium | latest triggers uncontrolled upgrades on every container rebuild. |
backup_retention_days | 7 (raise for prod) | Medium | Too short for compliance retention. |
