Infisical on Google Cloud Run

Infisical is an open-source, end-to-end encrypted secrets management platform: teams and CI/CD pipelines store, inject, and rotate application secrets from a single platform, using client SDKs, a CLI, or the web UI. This module deploys Infisical 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 Infisical 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

Infisical runs as a Node.js container (a custom-built image wrapping the official infisical/infisical image) on Cloud Run v2. The deployment wires together a focused set of Google Cloud services:

Capability	Google Cloud service	Notes
Compute	Cloud Run v2	Custom-built Node.js service, 1 vCPU / 2Gi by default, serverless autoscaling; scale-to-zero supported
Database	Cloud SQL for PostgreSQL 15	Required — Infisical does not support MySQL or other engines
Cache & rate-limiting	Redis (optional, on by default)	NFS-hosted Redis by default, or an authenticated external Redis via redis_auth
Secrets	Secret Manager	Auto-generated ENCRYPTION_KEY, AUTH_SECRET, ADMIN_PASSWORD; 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 mandatory. database_type defaults to POSTGRES_15 and is the only value Infisical supports.
• The container image is custom-built, not the upstream image. Infisical_Common builds FROM infisical/infisical:${INFISICAL_VERSION} with a wrapper entrypoint.sh that assembles the database connection string at container start (the runtime DB_PASSWORD Secret Manager value can't be URL-encoded at Terraform plan time). application_version = "latest" maps to a pinned known-good release (v0.162.10) as the build arg, per this catalog's convention against building latest-tag base images.
• Redis defaults on, and its wiring is mutually exclusive by construction. When redis_auth is empty (the default), the Foundation's own NFS-hosted Redis plain-env injection supplies REDIS_HOST/REDIS_PORT. When redis_auth is set, Infisical_Common instead creates and injects its own REDIS_URL secret. Only one path is ever active.
• The startup probe is TCP, not HTTP. Infisical does expose an unauthenticated /api/status endpoint that returns 200 with JSON when healthy — but only once the app reports full readiness (database + Redis + dependencies). An HTTP startup probe against that path would never pass, so the module defaults to a TCP probe (succeeds as soon as the port is bound) and disables the liveness probe entirely to avoid restart-looping a container that is still coming up.
• No object storage is mounted. A generic data GCS bucket is provisioned via the Foundation's storage_buckets variable, but gcs_volumes is empty by default — Infisical keeps all persistent state in PostgreSQL and needs no bucket mount.
• The admin account is bootstrapped headlessly, not via the web UI. An admin-bootstrap init job runs the infisical CLI's bootstrap command against the running server, avoiding the "open until the first visitor claims it" signup window. On Cloud Run this job does not run automatically on apply — see §3.

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 Infisical service

Infisical 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.

• 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

Infisical stores all application data (secrets, projects, organizations, users, audit logs) in a managed Cloud SQL for PostgreSQL 15 instance. The service connects through the Cloud SQL Auth Proxy over a Unix socket (enable_cloudsql_volume = true by default); no public IP is exposed. On first deploy, the db-init initialization job creates the application database and role.

• 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. Redis (cache & rate-limiting)

Redis is enabled by default (enable_redis = true). When redis_host is left empty, the NFS server VM's IP is used as the default Redis host. When redis_auth is set, Infisical_Common provisions its own REDIS_URL Secret Manager secret instead of relying on the Foundation's plain-env injection.

• CLI:

  redis-cli -h <redis-host> ping
  # Confirm which Redis path is active in the running revision:
  gcloud run services describe <service-name> --region "$REGION" \
    --format='value(spec.template.spec.containers[0].env)'

D. Secret Manager

Three cryptographic secrets are generated automatically and stored in Secret Manager: ENCRYPTION_KEY (encrypts every secret Infisical stores), AUTH_SECRET (signs JWT session tokens), and ADMIN_PASSWORD (consumed only by the admin-bootstrap job, never injected into the running server). A REDIS_URL secret is created conditionally. The database password is managed separately by the foundation.

• Console: Security → Secret Manager.
• CLI:

  gcloud secrets list --project "$PROJECT" --filter="name~infisical"
  gcloud secrets versions access latest --secret=<secret-name> --project "$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.

• CLI:

  gcloud run services describe <service-name> --region "$REGION" --format='value(status.url)'

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.

• CLI:

  gcloud run services logs read <service-name> --project "$PROJECT" --region "$REGION" --limit 50

---

3. Infisical Application Behaviour

• First-deploy database setup. The db-init initialization job runs postgres:15-alpine, connects through the Cloud SQL Auth Proxy socket, and idempotently creates the application role and database (matching the DB_USER/ DB_NAME the Foundation injects). execute_on_apply = true, so this runs on every apply and is safe to re-run.
• The database connection string is assembled at container start, not baked in at plan time. Infisical accepts a single DB_CONNECTION_URI, but the runtime DB_PASSWORD (a Secret Manager value) isn't known when Terraform renders the image — entrypoint.sh URL-encodes it and builds the URI from the discrete DB_HOST/DB_PORT/DB_USER/DB_PASSWORD/DB_NAME values, branching sslmode on DB_HOST's shape (Unix socket path → disable; loopback → disable; raw private IP → require).
• The admin account is bootstrapped headlessly — but not automatically on Cloud Run. The admin-bootstrap init job (image infisical/cli:latest, depends on db-init) runs infisical bootstrap --ignore-if-bootstrapped against the running server's HTTP API to create the first super-admin, organization, and instance-admin machine identity. Because Cloud Run init jobs run strictly before the Service exists, this job can't reach a live server at apply time — execute_on_apply = false. Trigger it manually after confirming the service is healthy:

  curl -s "$SERVICE_URL/api/status"   # expect HTTP 200 with a JSON body
  gcloud run jobs execute <service>-admin-bootstrap --region "$REGION" --project "$PROJECT" --wait

  The job retries up to 20 times (15s apart) and is idempotent (--ignore-if-bootstrapped), so re-running it after a redeploy is harmless.
• The admin password lives only in Secret Manager. Retrieve the bootstrapped credential with:

  gcloud secrets versions access latest --secret=<prefix>-infisical-admin-password --project "$PROJECT"

  It is never injected into the running server container — only into the admin-bootstrap job.
• Health endpoint. /api/status returns HTTP 200 with a JSON body once Infisical, its database connection, and (if enabled) Redis are all healthy — but the platform's startup/liveness probes deliberately do not poll it directly (see §1); use it for your own manual health checks and external uptime monitoring instead.
• Redis is optional but on by default. Set enable_redis = false only if you are certain no caching/rate-limiting backend is desired; Infisical falls back to in-memory behaviour without Redis but loses cross-instance consistency once max_instance_count > 1.

4. Configuration Variables

Variables are grouped exactly as they appear on the deployment platform. Only settings specific to or notable for Infisical are listed; every other input is inherited from App_CloudRun with its standard behaviour.

Group 1 — Project & Identity

Variable	Default	Description
project_id	(required)	Target Google Cloud project.
region	us-central1	Region for the service and regional resources.

Group 2 — Deployment Environment

Variable	Default	Description
tenant_deployment_id	demo	Short suffix that makes resource names unique per environment.
support_users	[]	Emails granted project access and monitoring alerts.
resource_labels	{}	Labels applied to all resources.

Group 3 — Application Identity

Variable	Default	Description
application_name	infisical	Base name for resources. Do not change after first deploy.
display_name	Infisical	Human-readable name shown in the Console.
description	Infisical - Open Source Secrets Management	Service description.
application_version	latest	Image version tag. "latest" maps to a pinned build arg (v0.162.10) — Infisical's own docs recommend never running bare latest in production.
site_url	""	Public URL for SITE_URL (invite/email links, CORS) and the admin-bootstrap CLI target. Defaults to this service's own computed run.app URL when empty.
admin_email	admin@techequity.cloud	Email for the bootstrapped first super-admin account.
admin_organization	Default Organization	Organization name created for the bootstrapped account.

Group 4 — Runtime & Scaling

Variable	Default	Description
deploy_application	true	Set false to provision infrastructure only.
container_image_source	custom	custom builds Infisical_Common's Dockerfile; prebuilt deploys container_image directly.

min_instance_count	0	0 enables scale-to-zero.
max_instance_count	3	Safe above 1 — migrations use a distributed Postgres advisory lock and auth is JWT-based (no sticky in-memory session state).
enable_image_mirroring	true	Mirror the built image into Artifact Registry.

Group 5 — Access & Ingress Control

Variable	Default	Description
ingress_settings	all	Public access; Infisical is typically reached by both browsers and CLI/SDK clients.

enable_iap	false	Require Google sign-in in front of Infisical.
smtp_host / smtp_port / smtp_user / smtp_password / smtp_secure_enabled / mail_from	various	Declared but not forwarded to Infisical_Common — inert, no effect on the deployment.

Group 6 — Environment Variables & Secrets

Variable	Default	Description
environment_variables	{}	Extra non-secret settings. Core Infisical vars (HOST, SITE_URL, DB_CONNECTION_URI) are set automatically.
secret_environment_variables	{}	Map of env var → Secret Manager secret name.
secret_propagation_delay	30	Seconds to wait after secret creation before proceeding.
secret_rotation_period	2592000s	Secret Manager rotation notification frequency.

Standard App_CloudRun Cloud Armor / CDN / Artifact Registry retention inputs — see App_CloudRun.

Group 11 — Storage & Filesystem

Variable	Default	Description
create_cloud_storage	true	Create GCS buckets defined in storage_buckets.
storage_buckets	[{ name_suffix = "data" }]	Foundation-level default bucket — provisioned but never mounted; Infisical needs no object storage.
enable_nfs	(Foundation default)	Only relevant here as the default source of the Redis host IP when redis_host is empty.
gcs_volumes	[]	GCS buckets mounted via GCS Fuse. Empty by default and unused by Infisical.

Group 12 — Database Backend

Variable	Default	Description
database_type	POSTGRES_15	Fixed — Infisical requires PostgreSQL.
db_name	infisical	PostgreSQL database name. Do not change after initial deployment.

Variable	Default	Description
initialization_jobs	[]	Leave empty to use Infisical_Common's default db-init + admin-bootstrap jobs.
cron_jobs	[]	Recurring jobs triggered by Cloud Scheduler.

Group 14 — Observability & Health

Variable	Default	Description
startup_probe	TCP, container_port	Forwarded to Infisical_Common. TCP, not HTTP /api/status — see §1.
liveness_probe	disabled	Forwarded to Infisical_Common. Disabled for the same reason as the startup probe.
uptime_check_config	{ enabled=true, path="/" }	Cloud Monitoring uptime check — consider pointing path at /api/status for a meaningful external health signal.

Group 21 — Redis Cache

Variable	Default	Description
enable_redis	true	Enable Redis for caching and rate-limiting.
redis_host	""	Leave blank to default to the NFS server IP.
redis_port	6379	Redis port.

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.

Setting	Sensible value	Risk	Consequence if wrong
ENCRYPTION_KEY (auto-generated)	Never rotate after first boot	Critical	Rotating it makes every previously stored secret permanently undecryptable.
AUTH_SECRET (auto-generated)	Only rotate in a maintenance window	Critical	Rotating it invalidates all active user sessions.
db_name / db_user	Set once	Critical	Immutable after first deploy; renaming recreates the DB/user and destroys all data.
enable_redis	Forward var.enable_redis unconditionally to App_CloudRun	Critical	Hardcoding it to false at the Foundation call leaves REDIS_URL completely unset in the common no-auth case — Infisical crashes at boot with "Either REDIS_URL, REDIS_SENTINEL_HOSTS or REDIS_CLUSTER_HOSTS must be defined".
database_type	POSTGRES_15	Critical	Any non-Postgres value is rejected by validation, or (if it were somehow set) Infisical would fail to connect entirely — MySQL is not supported.
startup_probe / liveness_probe	Keep the module defaults (TCP startup, disabled liveness)	High	Pointing either at HTTP /api/status makes the Cloud Run revision never become Ready — that endpoint only returns 2xx after full readiness (DB + Redis + deps), and Cloud Run won't route traffic to a service still waiting on its own startup probe.
admin-bootstrap job	Trigger manually after first healthy deploy	High	Without triggering it, no admin account exists and the instance is unusable from the UI/API until the job is run.
site_url	Leave empty for the auto-computed run.app URL, or set explicitly for a custom domain	Medium	An incorrect value breaks invite/email links, CORS, and the admin-bootstrap job's target.
smtp_host / smtp_user / smtp_password / mail_from / cubejs_api_url / hub_api_url	N/A	Low	These variables are declared for convention-mirroring parity but are never forwarded to Infisical_Common — setting them has no effect.
memory_limit	2Gi (default) or higher	Medium	Lower values risk OOM under concurrent secret-fetch load.
