NocoDB on GKE Autopilot
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 GKE Autopilot on top of the App_GKE foundation, which provisions and manages the shared Google Cloud and Kubernetes 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 that are common to every GKE application — Workload Identity, ingress, autoscaling, CI/CD, Cloud Armor, IAP, Binary Authorization, VPC Service Controls, backups, and the deployment lifecycle — refer to the App_GKE foundation guide rather than repeating them here.
1. Overview
NocoDB runs as a Node.js workload. The deployment wires together a focused set of Google Cloud services:
| Capability | Google Cloud service | Notes |
|---|---|---|
| Compute | GKE Autopilot | Node.js pods, 1 vCPU / 1 GiB by default, horizontally autoscaled |
| 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 replicas |
| Secrets | Secret Manager | Auto-generated JWT secret (NC_AUTH_JWT_SECRET) and database password |
| Ingress | Cloud Load Balancing | External LoadBalancer, optional custom domain + managed certificate |
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 enabled by default in the GKE variant (
enable_cloudsql_volume = true), but NocoDB's internal URL constructor requires a TCP host — the private IP is used, not the Unix socket path. - NFS is disabled by default. NocoDB stores file attachments in Cloud Storage, not on a shared filesystem.
- Redis is disabled by default. A single replica runs without Redis; enable it before scaling beyond one pod.
- 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, though a
db-initjob is still provided to create the database and user. - Health probes target
/api/v1/health, the dedicated health endpoint NocoDB exposes.
2. Google Cloud Services & How to Explore Them
All commands assume you have run
gcloud container clusters get-credentials <cluster> --region <region> --project <project>
and that PROJECT, REGION, and NAMESPACE are set. The namespace and other
identifiers are reported in the deployment Outputs.
A. GKE Autopilot — the NocoDB workload
NocoDB pods are scheduled on Autopilot, which bills for the CPU/memory the pods actually request. Horizontal Pod Autoscaling sizes the deployment between the minimum and maximum replica counts.
- Console: Kubernetes Engine → Workloads → select the NocoDB workload to see pods, revisions, and events. Kubernetes Engine → Services & Ingress shows the external IP.
- CLI:
kubectl get pods,svc,hpa -n "$NAMESPACE"
kubectl logs -n "$NAMESPACE" deploy/<service-name> --tail=100
kubectl describe hpa -n "$NAMESPACE" # current vs target utilisation
See App_GKE for how Autopilot, scaling, and the workload type (Deployment vs StatefulSet) are managed.
B. Cloud SQL for PostgreSQL 15
NocoDB stores all application data (tables, views, automations, row data) in a managed Cloud SQL for PostgreSQL 15 instance. Pods reach it over a private IP TCP connection. On first deploy an initialization Job creates the application database and user; NocoDB then runs its own schema migrations on startup.
- Console: SQL → select the instance for connections, backups, flags, and metrics.
- CLI:
gcloud sql instances list --project "$PROJECT"
gcloud sql instances describe <instance-name> --project "$PROJECT"
# Open an interactive shell to inspect schema/data:
gcloud sql connect <instance-name> --user=<db-user> --project "$PROJECT"
The instance name, database name, user, and the Secret Manager secret holding the password are all surfaced in the Outputs. For the connection model, automated backups, and password rotation, see App_GKE.
C. Cloud Storage — file uploads
NocoDB stores file attachments in a dedicated Cloud Storage bucket. The bucket
name is injected into the container as GCS_BUCKET_NAME automatically. The
workload service account is granted access via Workload Identity.
- Console: Cloud Storage → Buckets → select the uploads bucket.
- CLI:
gcloud storage buckets list --project "$PROJECT"
gcloud storage ls gs://<uploads-bucket>/ # bucket name is in the Outputs
See App_GKE for CMEK and additional bucket options.
D. Redis cache (optional)
Redis backs NocoDB's caching layer and, in multi-replica deployments, keeps cache
state consistent across pods. Redis is disabled by default; a redis_host must be
supplied when it is enabled.
- Console: Memorystore → Redis (if using a managed instance).
- CLI:
redis-cli -h <redis-host> ping
redis-cli -h <redis-host> info keyspace
E. Secret Manager
The NocoDB JWT secret (NC_AUTH_JWT_SECRET) and the database password are stored as
Secret Manager secrets and injected into pods at runtime; plaintext never appears
in configuration.
- Console: Security → Secret Manager.
- CLI:
gcloud secrets list --project "$PROJECT"
gcloud secrets versions access latest --secret=<secret-name> --project "$PROJECT"
The database password secret name is in the Outputs. See App_GKE for the Secret Store CSI integration and rotation.
F. Networking & ingress
By default the workload is exposed through an external Cloud Load Balancing IP. A custom domain with a Google-managed certificate can be enabled, and a static IP can be reserved so the address survives redeploys.
- Console: Network services → Load balancing; VPC network → IP addresses.
- CLI:
kubectl get ingress,svc -n "$NAMESPACE"
gcloud compute addresses list --project "$PROJECT"
See App_GKE for custom domains, Cloud CDN, and static IP details.
G. Cloud Logging & Monitoring
Pod stdout/stderr flow to Cloud Logging; GKE and Cloud SQL metrics flow to Cloud
Monitoring. Optional uptime checks against /api/v1/health and alert policies are
available.
- Console: Logging → Logs Explorer; Monitoring → Dashboards / Alerting.
- CLI:
gcloud logging read 'resource.type="k8s_container" AND resource.labels.namespace_name="'"$NAMESPACE"'"' \
--project "$PROJECT" --limit 50
3. NocoDB Application Behaviour
- First-deploy database setup. An initialization Job (
db-init) creates the NocoDB database and user before the application starts. It is idempotent and safe to re-run. - Self-managed migrations. NocoDB runs its own database schema migrations on first 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; the Service Account is granted object-level access via Workload Identity. - 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. - Health path. Readiness and liveness probes target
/api/v1/health, which returns HTTP 200 when NocoDB is ready to accept requests. - Multi-replica sessions. With more than one pod and no Redis, NocoDB cannot
share session or cache state; users may be logged out when requests route to a
different pod. Enable Redis and set
redis_hostbefore scaling above one replica.

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. |
quota_memory_requests / _limits | binary units | Critical | Bare integers are bytes and block all scheduling. |
container_resources.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 replica | High | Multiple pods without Redis cause session invalidation when requests route to different pods. |
redis_host | explicit when Redis on | High | A missing host causes all Redis connections to fail on pod startup. |
min_instance_count | 1 | High | 0 allows 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 from the load-balancer IP. |
backup_retention_days | 7 (raise for prod) | Medium | Too short for compliance retention. |
pdb_min_available vs min_instance_count | leave headroom | Medium | 1/1 can stall node upgrades (single pod cannot be evicted). |
application_version | pin to specific tag | Medium | latest triggers uncontrolled upgrades on every container rebuild. |
For the foundation behaviour referenced throughout — IAM and Workload Identity, autoscaling, ingress and certificates, CI/CD, Cloud Armor, IAP, Binary Authorization, VPC-SC, backups, and image mirroring — see App_GKE. NocoDB-specific application configuration shared with the Cloud Run variant is described in NocoDB_Common.
