Gotify on Google Cloud Run

Gotify on Google Cloud Run

Gotify is an open-source (MIT-licensed), self-hosted server for sending and receiving real-time push notifications. Applications post messages over a simple REST API and clients receive them instantly over WebSocket streams. This module deploys Gotify 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 Gotify 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.


What Gotify costs on RAD, and how that compares​

Running Gotify on Cloud Run in your own Google Cloud project costs about $115.17/month in Google Cloud charges, on top of a one-off 75-credit RAD module fee charged once at deploy time. Gotify's job is small — accept a webhook, fan it out over WebSocket — but this deployment still needs a database and a file server behind it, which is most of the $115.17 above. In a RAD-managed project the module fee drops to 67.5 credits (10% lower) and the running cost is metered hourly in credits instead of billed directly by Google — see Pause it for free below for the one RAD-managed advantage a self-hosted VPS cannot match — or see the GKE guide if you'd rather run it on Kubernetes.

How it compares​

  • A self-managed comparison: Hetzner CPX22 (2 vCPU/4GB) runs about $24/mo, a DigitalOcean 2 vCPU/4GB Droplet is the same $24/mo, and a GCP Compute Engine e2-standard-2 (2 vCPU/8GB) is about $49/mo — any of those is enough to run Gotify and its Postgres database together in Docker Compose on one box, at a lower sticker price than RAD's managed stack.
  • What that price doesn't include: backups, security patches, TLS renewal, and disk-full 2am pages, all of which RAD's managed Cloud SQL, Secret Manager and monitoring absorb for you.
  • Gotify has no official hosted SaaS version of its own — it only ships as self-hosted software, so the choice is really "manage a VPS yourself" or "let RAD manage the same stack", not RAD-vs-a-subscription.

Pause it for free: delete a RAD-managed project, restore it when you need it​

This is the headline advantage of a RAD-managed project, and it costs nothing while paused. Deleting a RAD-managed project unlinks its billing first, then asks Google to delete the project outright — Google's own 30-day recoverable soft delete. Unlike deleting one module, this does not tear down Cloud SQL, any VM, or the compute resource one by one: the whole project simply stops, and nothing is charged while it waits, because billing is already unlinked.

Restoring, within 30 days and only by the project's owner, asks Google to undelete the project and reattaches its billing account, then asks you to run Update on each deployment to confirm everything came back. Because nothing was individually destroyed, that Update finds the same resources already there — it is a check, not a rebuild, and an Update never charges the module fee again. This costs only a handful of credits (under US$1) in total for a typical 2-3-deployment chain.

What this needs: you must own the project (not one RAD only manages billing for), you must restore it yourself within 30 days — after that Google deletes it for good — and restoring is admitted like creating a new project, so your purchased credit balance must still clear the tier's floor (100 credits for the sandbox tier most study/demo use fits). Google says most services are fully working again within 36 hours of a restore.

One real gap: nightly backups are written to a bucket inside the project, and that bucket has Cloud Storage's soft-delete explicitly turned off, so it is very likely gone as soon as you delete the project — even though the project itself is recoverable for 30 days. If you've customised Gotify and want to keep that work, copy a backup out (to Google Drive, or a bucket outside the project) before deleting. For a default install with nothing irreplaceable in it, this does not matter.

Pay only while you use it, the other way: delete and redeploy​

In your own project, or once 30 days have passed on a RAD-managed one, there is no free pause — deleting removes the resources for good, and bringing Gotify back means redeploying from scratch. That costs about 78-81 credits (the 75-credit module fee plus a build).

Deleting only saves money once Gotify would otherwise sit unused long enough to clear that redeploy cost against its own running cost — for Gotify, that's about 3 days or more. Most of that running cost is usually the database (and, where this module uses one, the shared file-server VM or GKE cluster) — those stop only once nothing else in the project uses them, so deleting this app while something else shares the project saves only its own compute share.

Keep data first: nightly backups go to a bucket inside the deployment and are deleted with it, so copy the latest backup out before deleting if you want to keep it.

Lab sessions and Managed Environments​

Lab sessions, for training: a trainer runs a session for a class. Each participant gets the app in their own Google Cloud project for 15 minutes to 24 hours, within an allowance the trainer sets. Either the trainer funds every place, or each participant pays for their own. Everything is deleted when the session ends and unused credits go back to the trainer.

Managed Environments, for consultancies: a partner runs the app for a client from a ring-fenced wallet it funds, and settles with the client directly. If the wallet runs low, billing pauses and the data is kept, so nobody receives an unexpected charge. At the end the partner hands the project over and the deployments become the client's own.

Credits can be bought in more than 20 currencies, including XAF, XOF, NGN, GHS, KES and ZAR, by card, bank transfer or mobile money.

1. Overview​

Gotify runs as a single-binary Go container on Cloud Run v2. The deployment wires together a focused set of Google Cloud services:

CapabilityGoogle Cloud serviceNotes
ComputeCloud Run v2Go service, 1 vCPU / 512 MiB by default, always-on CPU for WebSocket streams
DatabaseCloud SQL for PostgreSQL 15Required — this module never uses Gotify's embedded SQLite
SecretsSecret ManagerAuto-generated admin password (GOTIFY_DEFAULTUSER_PASS); database password
Container buildCloud Build + Artifact RegistryWraps ghcr.io/gotify/server with a DB-mapping entrypoint
IngressCloud Run URL / Cloud Load BalancingDefault run.app URL; optional external HTTPS load balancer + custom domain

Sensible defaults worth knowing up front:

  • PostgreSQL 15 is mandatory. database_type = "POSTGRES_15" is fixed by the shared application layer; Gotify's SQLite mode is not used, so no persistent disk is required.
  • The container listens on port 80. container_port = 80 and the entrypoint sets GOTIFY_SERVER_PORT = 80.
  • CPU is always allocated (cpu_always_allocated = true) with min = max = 1. Gotify holds long-lived WebSocket streams and an in-process message bus, so CPU must not be throttled between requests. This defeats scale-to-zero; a low-traffic instance can flip cpu_always_allocated = false, accepting that stream delivery pauses while idle.
  • A single instance is the safe default. Gotify's message bus is in-process, so a client stream only receives messages delivered to the instance it is connected to. Scaling beyond one instance without an external fan-out layer drops messages for some subscribers.
  • The admin password is generated automatically and stored in Secret Manager, injected as GOTIFY_DEFAULTUSER_PASS. The initial admin (admin) is created on the first database initialisation only.
  • No object storage bucket is provisioned (storage_buckets = []). Messages, applications, and tokens live in PostgreSQL; uploaded application images and plugins live on the NFS share at /app/data (enable_nfs = true, which must stay on — otherwise they vanish on every new revision or cold start).
  • The image is custom-built. container_image_source = "custom" builds a wrapper around ghcr.io/gotify/server that maps the platform DB_* variables onto Gotify's GOTIFY_DATABASE_* (GORM) configuration; latest pins to base 2.9.1.
  • Public ingress is the default. ingress_settings = "all" so sending applications and receiving clients can reach the REST API and WebSocket.

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 Gotify service​

Gotify runs as a Cloud Run v2 service. Each deployment creates an immutable revision; traffic can be split across revisions for safe rollouts. Because CPU is always allocated and a single instance is maintained, WebSocket streams stay connected between message sends.

  • 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​

Gotify stores all application data (messages, applications, clients, users) in a managed Cloud SQL for PostgreSQL 15 instance. The service connects privately through the Cloud SQL Auth Proxy over a Unix socket; no public IP is exposed. On first deploy an initialization Job creates the application database and role; Gotify then applies its own schema via GORM auto-migration on first 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> --database=<db-name> --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. Secret Manager​

The admin password (GOTIFY_DEFAULTUSER_PASS) is generated automatically and stored in Secret Manager. The database password is managed separately by the foundation.

  • Console: Security → Secret Manager.
  • CLI:
    gcloud secrets list --project "$PROJECT" --filter="name~gotify"
    gcloud secrets versions access latest --secret=<secret-name> --project "$PROJECT"

See App_CloudRun for injection and rotation details.

D. Container build & Artifact Registry​

The custom image wraps ghcr.io/gotify/server with a DB-mapping entrypoint. Cloud Build builds it and pushes to Artifact Registry; enable_image_mirroring = true mirrors the upstream base into Artifact Registry to avoid registry rate limits.

  • Console: Cloud Build → History; Artifact Registry → Repositories.
  • CLI:
    gcloud builds list --project "$PROJECT" --limit 5
    gcloud artifacts repositories list --project "$PROJECT"

E. Networking & ingress​

The service is reachable at its run.app URL by default, which allows the public access required for sending applications and receiving clients. An external HTTPS load balancer with a custom domain, Cloud CDN, and Cloud Armor can be layered on.

  • 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.

F. Cloud Logging & Monitoring​

Container logs flow to Cloud Logging; Cloud Run and Cloud SQL metrics flow to Cloud Monitoring, with an optional uptime check against /health (disabled by default) and optional alert policies.

  • Console: Logging → Logs Explorer; Monitoring → Dashboards / Alerting.
  • CLI:
    gcloud run services logs read <service-name> --project "$PROJECT" --region "$REGION" --limit 50

3. Gotify Application Behaviour​

  • First-deploy database setup. An initialization Job runs create-db-and-user.sh using postgres:15-alpine. It connects through the Cloud SQL Auth Proxy and idempotently creates the application database and role and grants privileges. The job is safe to re-run.
  • Schema via GORM auto-migration. Gotify creates and migrates its own tables on every startup — there is no separate migration job. Upgrading the application version applies schema changes automatically.
  • The admin account is bootstrapped once. GOTIFY_DEFAULTUSER_NAME = admin and the GOTIFY_DEFAULTUSER_PASS secret create the initial administrator on the first database initialisation only. Retrieve the password from Secret Manager and change it after first login. Changing the secret later does not reset the admin password.
  • Send and receive are token-authenticated. After logging in, create an application (which yields an app token) to send messages via POST /message?token=<apptoken>, and use a client token to subscribe over the WebSocket at /stream?token=<clienttoken>. Confirm health without a token:
    curl -s "$(gcloud run services describe <service-name> --region "$REGION" \
    --project "$PROJECT" --format='value(status.url)')/health"
  • Single-instance WebSocket delivery. Because the message bus is in-process, keep max_instance_count = 1 unless you add an external fan-out layer — otherwise a message sent to one instance is not delivered to clients streaming from another.
  • Health path. Startup and liveness probes target /health — the public endpoint that returns {"health":"green","database":"green"} once PostgreSQL is reachable. The default startup probe allows ~5 minutes on first boot.
  • Inspect job execution:
    gcloud run jobs list --project "$PROJECT" --region "$REGION"
    gcloud run jobs executions list --job <job-name> --project "$PROJECT" --region "$REGION"

6. Configuration Pitfalls & Sensible Defaults​

Risk: Critical (data loss / outage / security) — High (service degraded) — Medium (cost or partial degradation) — Low (minor).

Inherited plan-time validation. This module passes its configuration through the App_CloudRun foundation engine, which validates values and combinations at plan time — IAP with no authorized identities, a gen1 runtime with NFS/GCS mounts, an out-of-range redis_port/backup_retention_days, a database_type that does not match an enabled extension. Invalid configuration fails the plan with a clear, named error before any resource is created.

SettingSensible valueRiskConsequence if wrong
max_instance_count1CriticalScaling beyond 1 without external fan-out drops messages for clients streaming from other instances (in-process message bus).
application_database_name / application_database_userSet onceCriticalImmutable after first deploy; renaming recreates the DB/role and destroys all messages.
enable_backup_importfalse unless restoringCriticalEnabling without a valid backup fails the import job.
cpu_always_allocatedtrueHighUnder request-based billing, CPU throttles between requests and WebSocket stream delivery stalls while idle.
container_port80HighGotify listens on 80; a mismatched port fails the startup probe and the revision never serves.
memory_limit512MiHighBelow the gen2 512 MiB floor the plan is rejected.
min_instance_count1HighScale-to-zero drops all live WebSocket streams whenever the instance is reclaimed.
ingress_settingsallHighinternal blocks external senders and receivers from reaching the service.
enable_iaponly when API callers carry identityHighIAP requires Google identity on every request, blocking token-only send/receive callers.
GOTIFY_DEFAULTUSER_PASS (auto-generated)Change admin password after first loginHighThe bootstrap password only applies on first init; leaving the default admin password unchanged is a standing credential exposure.
backup_retention_days7 (raise for prod)MediumToo short for compliance retention.
enable_cloud_armorenable for productionMediumThe API and UI are publicly reachable without WAF protection.

For the foundation behaviour referenced throughout — service identity, scaling and concurrency, ingress and load balancing, CI/CD, Cloud Armor, IAP, Binary Authorization, VPC-SC, backups, and image mirroring — see App_CloudRun. Gotify-specific application configuration shared with the GKE variant is described in Gotify_Common.
