Wallabag on Google Cloud Run

Wallabag on Google Cloud Run

Wallabag is a free, open-source, self-hosted "read it later" article archiving app — a Pocket alternative. Save articles from a browser extension, bookmarklet, mobile app, or the REST API, then read them later in a clean, distraction-free view with full-text search, tagging, annotations, and RSS feeds of your saved items. This module deploys Wallabag 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 Wallabag 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 Wallabag costs on RAD, and how that compares​

Running Wallabag on Cloud Run in your own Google Cloud project costs about US$70.19/month in Google Cloud charges, on top of a one-off 75-credit RAD module fee (US$7.50) charged once at deploy time. Wallabag is a self-hosted read-it-later article archiver, and its managed MySQL database is most of this running cost. In a RAD-managed project the module fee drops to 67.5 credits (10% lower) — see Pause it for free below — or see the GKE guide if you'd rather run it on Kubernetes.

How it compares​

  • wallabag's own creators sell official hosting at wallabag.it: plans run from about €11/year (roughly $1/month) up to a €30/year "heart" subscription that just adds extra project support on identical features — verified on wallabag.it, 8 October 2026. That is far cheaper than RAD's own-project running cost here, because wallabag.it is a shared, multi-tenant service built for personal use; it is not a like-for-like comparison against a dedicated, isolated project with your own Cloud SQL instance and full data control.
  • A self-managed VPS comparison, sized to Wallabag's 1 vCPU / 2 GiB default: a Hetzner CPX22 or DigitalOcean 2 vCPU/4GB Droplet runs about $24/month — cheaper in cash terms, plus your own time for MySQL backups and patching, which RAD's managed Cloud SQL and Secret Manager cover for you.
  • For simple personal use, wallabag.it's own hosting is the cheapest option by far; RAD's case here is a dedicated project — useful for a team archive, a self-serve lab deployment, or anyone who wants the data to never leave infrastructure they control.

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 Wallabag 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 Wallabag back means redeploying from scratch. That costs about 78-81 credits in your own project, or about 70.5-73.5 credits in a RAD-managed one.

Deleting only saves money once Wallabag would otherwise sit unused long enough to clear that redeploy cost against its own running cost — about 3 days or more in your own project (about US$2.34 a day), or about 3 days or more in a RAD-managed one (26 credits a day).

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​

Wallabag runs as a PHP/Symfony container (nginx + php-fpm under s6-overlay) on Cloud Run v2. The deployment wires together a focused set of Google Cloud services:

CapabilityGoogle Cloud serviceNotes
ComputeCloud Run v2PHP/Symfony service, 1 vCPU / 2 GiB by default, serverless autoscaling; scale-to-zero by default
DatabaseCloud SQL for MySQL 8.0Required — Wallabag_Common fixes the engine; PostgreSQL is not supported
Object storageCloud StorageA generic data bucket is provisioned, but Wallabag does not read or write it — all content lives in MySQL
SecretsSecret ManagerAuto-generated APP_SECRET (Symfony security token); database password
IngressCloud Run URL / Cloud Load BalancingDefault run.app URL; optional external HTTPS load balancer + custom domain

Sensible defaults worth knowing up front:

  • MySQL 8.0 is mandatory. The database engine is fixed by Wallabag_Common; selecting any other engine breaks the deployment.
  • enable_cloudsql_volume = false. Cloud Run connects to Cloud SQL over private-IP TCP, not the Auth Proxy Unix socket. The GKE variant instead uses the Auth Proxy sidecar on 127.0.0.1.
  • Single Secret Manager secret. APP_SECRET (a Symfony security token) is generated automatically, overriding Wallabag's publicly-known baked-in default. There is no separate generated admin-password secret.
  • Scale-to-zero is enabled by default (min_instance_count = 0, max_instance_count = 1). Cold starts add latency to the first request after idle; set min_instance_count = 1 to avoid this.
  • enable_nfs defaults true but is functionally unused. It mounts Cloud Filestore NFS at /var/lib/wallabag, but Wallabag's image WORKDIR is /var/www/wallabag — nothing writes to the mounted path. Safe to disable.
  • No separate migration job. Wallabag's own bin/console wallabag:install handles both schema creation and first-run setup in one idempotent step.
  • Self-registration is disabled. SYMFONY__ENV__FOSUSER_REGISTRATION = "false" — only the bootstrapped administrator account exists until an operator explicitly enables sign-up or creates more accounts.

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 Wallabag service​

Wallabag 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 MySQL 8.0​

Wallabag stores all application data (saved articles, tags, users, annotations) in a managed Cloud SQL for MySQL 8.0 instance. The service connects over the instance's private IP via TCP (not the Auth Proxy socket — Cloud Run's enable_cloudsql_volume defaults false for this module). On first deploy, a db-init job creates the application database and user, followed by wallabag-install, which runs Wallabag's own installer to create the schema.

  • 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. Cloud Storage​

A generic data bucket is provisioned by default (via the Foundation's storage_buckets input), but Wallabag itself never reads or writes it — all content lives in MySQL, and gcs_volumes (which would fuse-mount a bucket into the container) is empty by default.

  • Console: Cloud Storage → Buckets.
  • CLI:
    gcloud storage buckets list --project "$PROJECT"

D. Secret Manager​

One secret is generated automatically and stored in Secret Manager: APP_SECRET (materialised under that simple key; aliased onto the real SYMFONY__ENV__SECRET name by the wrapper entrypoint). The database password is managed separately by the foundation.

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

See App_CloudRun for injection and rotation details.

E. 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.

  • 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 optional uptime checks 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. Wallabag Application Behaviour​

  • Two-stage init chain, not a Laravel-style separate migrate step. db-init (mysql:8.0-debian) creates the empty application database and user and grants privileges. wallabag-install then depends on db-init and reuses the same custom app image (so the wrapper entrypoint's env aliasing still runs) with its command overridden to bin/console wallabag:install --env=prod -n. This single command performs both schema creation and first-run setup (including seeding the default administrator account) — there is no separate migration job to run on upgrades; re-running wallabag:install against an already-installed database is safe and idempotent.
  • Health check behaviour. The startup probe is TCP on port 80 — it only needs nginx to bind, independent of installer progress. The liveness probe is HTTP GET /: an unauthenticated request to the root path returns an HTTP 302 redirect to /login, which both Cloud Run's and Kubernetes' health-check semantics treat as a passing response (any 2xx–3xx). Do not expect a bare 200 from / — a 302 to /login is the expected, healthy result.
    curl -s -o /dev/null -w "%{http_code}\n" "$SERVICE_URL/"   # expect 302
  • First-run administrator account. wallabag:install --env=prod -n creates Wallabag's own default administrator account using Wallabag's documented installation defaults (username and password both wallabag) — there is no Secret Manager secret holding a generated admin password. Change this password immediately after first login (Settings → your account → change password, or bin/console fos:user:change-password wallabag inside the container). New accounts cannot self-register (SYMFONY__ENV__FOSUSER_REGISTRATION = "false") — create additional users from the admin UI or with bin/console fos:user:create.
  • Inspect job execution:
    gcloud run jobs list --project "$PROJECT" --region "$REGION"
    gcloud run jobs executions list --job <job-name> --project "$PROJECT" --region "$REGION"

4. Configuration Variables​

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. Invalid configuration fails the plan with a clear, named error before any resource is created, so most mistakes below are caught up front rather than at apply or runtime.

SettingSensible valueRiskConsequence if wrong
DB driver env var (SYMFONY__ENV__DATABASE_DRIVER, hardcoded in entrypoint.sh)must be set explicitly (pdo_mysql here)CriticalWallabag's shipped parameters.yml defaults database_driver to pdo_sqlite. Setting only SYMFONY__ENV__DATABASE_HOST/_PORT/_NAME/_USER/_PASSWORD with no explicit driver var still silently installs against a throwaway local SQLite file — the install "succeeds," the app appears to work, but all data lives in an ephemeral file wiped on every restart or redeploy, and MySQL is never touched. No error is raised. If this module is ever cloned as a template for another Symfony-based application, verify the DB driver env var is set explicitly — this class of failure is undetectable from the outside; only comparing the container's boot logs ("Configuring the SQLite database..." vs. a MySQL connection line) reveals it. See App_CloudRun and App_GKE for how the Foundation injects DB env vars generically — the app-specific translation and any missing pieces are always the calling module's responsibility.
db_name / db_userSet onceCriticalImmutable after first deploy; renaming recreates the DB/user and destroys all saved articles.
APP_SECRET (auto-generated)Never hand-edit in Secret Manager after first bootHighWallabag uses this as a Symfony security-signing key; changing it invalidates CSRF tokens and any signed URLs already issued.
Default administrator credentials (wallabag / wallabag, seeded by wallabag:install)Change immediately after first loginHighThe installer seeds Wallabag's own well-known default credentials — anyone who knows the service URL and the public default can log in until the password is changed.
enable_backup_importfalse unless restoringCriticalEnabling without a valid backup_uri fails the import job.
container_image_sourcecustomCriticalSwitching to prebuilt deploys the stock wallabag/wallabag image with no wrapper entrypoint — the DB and secret env-var aliasing never runs, so the app cannot reach MySQL at all.
min_instance_count1 for productionMediumScale-to-zero (0) adds cold-start latency to the first request after idle.
enable_nfsfalse unless needed for another purposeLow / costDefaults true and provisions a Filestore share that Wallabag never uses — a needless recurring cost.
enable_cloud_armorenable for productionMediumThe service is publicly reachable without WAF protection by default.

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. Wallabag-specific application configuration shared with the GKE variant is described in Wallabag_Common.
