Navidrome on Cloud Run — Lab Guide

📖 Configuration Guide

Overview

Estimated time: 45–90 minutes

Navidrome is a free, open-source, self-hosted, Subsonic-compatible music streaming server written in Go. It has no external database — its entire state (library, users, playlists) lives in an embedded SQLite file. This lab takes you through the full operational lifecycle of the Navidrome 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 Navidrome 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, and retrieve the generated admin password.
  • Perform day-2 operations — inspect revisions, mount a music library, manage secrets and backups.
  • 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, Artifact Registry, and shared service accounts this module depends on — Navidrome itself needs no Cloud SQL instance).
  • A Google Cloud project with billing enabled.
  • gcloud CLI authenticated: gcloud auth login and gcloud 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]

  1. In the RAD platform, open Navidrome (Cloud Run), set project_id, and review the inputs. Configure only what you need — the Configuration Guide documents every input by group, with defaults. Note that the service defaults to ingress_settings = internal (VPC-private) and enable_admin_password = true (required if you plan to switch to public ingress). Review the estimated cost (if credits are enabled) and click Deploy, which opens the deployment status page with real-time logs.

  2. The platform provisions the Cloud Run service, a dedicated Cloud Storage bucket mounted at /data via GCS FUSE (the SQLite database, metadata cache, and search index all live there), a Secret Manager secret holding a generated 24-character admin password, and mirrors the deluan/navidrome image into Artifact Registry. There is no Cloud SQL instance and no database-initialisation job — Navidrome creates and migrates its own SQLite database on first boot. First deploys typically complete in 5–15 minutes, much faster than a database-backed module.

  3. 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="$REGION" \
    --filter="metadata.name~navidrome" --format="value(metadata.name)" --limit=1)
    SERVICE_URL=$(gcloud run services describe "$SERVICE" \
    --project="$PROJECT" --region="$REGION" --format="value(status.url)")
    echo "Service: $SERVICE"
    echo "URL: $SERVICE_URL"

    With the default ingress_settings = internal, $SERVICE_URL is reachable only from within the VPC (e.g. from a Compute Engine VM or a Cloud Shell with VPC access) — not directly from your local machine.


Task 2 — Access & verify [Manual]

  1. Confirm the service is healthy. Navidrome exposes an unauthenticated ping endpoint that responds once the server has booted:

    curl -s "$SERVICE_URL/ping"   # expect {"status":"ok"}
  2. Retrieve the generated admin password from Secret Manager:

    SECRET=$(gcloud secrets list --project="$PROJECT" \
    --filter="name~navidrome-admin-password" --format="value(name)" --limit=1)
    gcloud secrets versions access latest --secret="$SECRET" --project="$PROJECT"
  3. Open $SERVICE_URL in a browser (from a VPC-connected host, or after temporarily switching ingress_settings = all) and log in as admin with the retrieved password. Change the password immediately after first login. If enable_admin_password = false was chosen instead, the first visitor completes a create-admin wizard — do this yourself right away.

  4. The music library is empty until you mount one. Add a gcs_volumes entry (or enable NFS) pointing /music at your audio collection, then apply via Update — Navidrome scans ND_MUSICFOLDER (/music) on every start.


Task 3 — Operate & keep it running (Day-2) [Manual]

  1. 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"
  2. Do not scale beyond one instance. min_instance_count = 1 keeps the server warm (avoiding cold-start latency mid-stream); max_instance_count = 1 must stay at 1 — Navidrome is a single-writer server, and multiple instances writing to the same SQLite file over GCS FUSE will corrupt the library. Both are configuration inputs on the deployment details page, not something to change with a manual gcloud edit (a manual edit would be reverted on the next apply).

  3. Update the application version by changing the version input in the RAD platform and applying it via Update; a new image builds (pinned via the NAVIDROME_VERSION build arg) and a new revision rolls out.

  4. Manage secrets and backups:

    gcloud secrets list --project="$PROJECT" --filter="name~navidrome"
    gcloud run jobs list --project="$PROJECT" --region="$REGION" # scheduled backup job, if configured

    The backup_schedule input (default 0 2 * * * UTC) snapshots the /data bucket on a cron schedule; backup_retention_days controls how long snapshots are kept.

  5. Inspect the /data bucket directly (useful for confirming persistence across revisions):

    gcloud storage ls gs://<data-bucket-name>/   # bucket name is in the storage_buckets output

Task 4 — Observe: Logging & Monitoring [Manual]

  1. Logs — from the CLI or the Logs Explorer:

    gcloud run services logs read "$SERVICE" --project="$PROJECT" --region="$REGION" --limit=50

    Logs Explorer filter: resource.type="cloud_run_revision" AND resource.labels.service_name="<service>".

  2. Monitoring — open the Cloud Run dashboard for the service and review request count, request latency, instance count, and CPU / memory utilisation (Navidrome holds its search index in memory, so watch memory closely on a large library). An uptime check is only provisioned when the endpoint is publicly reachable (custom domain, or ingress_settings = all) — with the default internal ingress, no uptime check fires; confirm under Monitoring → Uptime checks only after switching to public ingress.


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 Navidrome releases.

  • Revision unhealthy / service won't serve: inspect the latest revision and its logs for startup errors. The startup probe targets GET /ping with a 15-second initial delay and a generous retry window; the liveness probe polls every 30 seconds.
    gcloud run revisions list --service="$SERVICE" --project="$PROJECT" --region="$REGION"
    gcloud run services logs read "$SERVICE" --project="$PROJECT" --region="$REGION" --limit=100
  • Empty library / no songs found: confirm a gcs_volumes entry (or NFS mount) is actually attached at /music — the module does not mount a music source automatically, so an unconfigured deployment has nothing to scan.
  • Public URL rejected at plan time: ingress_settings = "all" is blocked unless enable_admin_password = true — this is intentional, so a stranger can never reach an open first-run wizard on a public URL.
  • /data looks wiped after a redeploy: confirm the storage bucket was not deleted or repointed — it is the single source of truth for the SQLite database, users, and playlists.
  • 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 & Sensible Defaults section for setting-specific gotchas (including why max_instance_count must never exceed 1, and why execution_environment must stay gen2).


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, the /data Cloud Storage bucket (this permanently deletes the music library metadata, users, and playlists — there is no Cloud SQL to separately back up), the Secret Manager admin-password secret, and Artifact Registry images. Resources owned by Services_GCP (the VPC, shared Cloud SQL, registry) are managed separately and are not removed here.
