GCP Cloud Run Deploy
Deploy from source to Cloud Run in a single command. Requires: a GCP project, a Dockerfile in the repo root, and an app that listens on a port (default 8080 / PORT env var).
Quick Deploy
# 1. Auth (skip if already logged in)
gcloud auth login
gcloud config set project PROJECT_ID
# 2. Enable APIs (first time only)
gcloud services enable run.googleapis.com cloudbuild.googleapis.com artifactregistry.googleapis.com
# 3. Deploy
gcloud run deploy SERVICE_NAME \
--source . \
--region australia-southeast1 \
--allow-unauthenticatedThis builds the container remotely via Cloud Build, pushes to Artifact Registry, deploys to Cloud Run, and returns a public HTTPS URL. Redeploy by re-running the same command.
Deploy Script
Copy scripts/deploy.sh into the project root for one-command deploys:
chmod +x deploy.sh
./deploy.sh my-serviceEnv vars: GCP_REGION (default australia-southeast1), GCP_PROJECT (default: current gcloud project).
Common Flags
| Flag | Purpose | Example |
|---|---|---|
--region | Deployment region | australia-southeast1 |
--allow-unauthenticated | Public access | |
--port | Container port (if not 8080) | --port 3000 |
--set-env-vars | Env vars | --set-env-vars KEY=val,FOO=bar |
--set-secrets | Secret Manager secrets | --set-secrets ENV=SECRET:latest |
--memory | Memory | --memory 512Mi |
--cpu | CPU | --cpu 1 |
--min-instances | Min instances (0 = scale to zero) | --min-instances 0 |
--max-instances | Max instances | --max-instances 3 |
--timeout | Request timeout (max 3600) | --timeout 300 |
Environment Variables and Secrets
Inline env vars:
gcloud run deploy SERVICE --source . --region REGION --allow-unauthenticated \
--set-env-vars "DATABASE_URL=postgres://...,API_KEY=abc123"Secret Manager (recommended for sensitive values):
# Create secret
echo -n "secret-value" | gcloud secrets create MY_SECRET --data-file=-
# Grant access to default compute SA
gcloud secrets add-iam-policy-binding MY_SECRET \
--member="serviceAccount:$(gcloud iam service-accounts list --format='value(email)' --filter='displayName:Compute Engine default')" \
--role="roles/secretmanager.secretAccessor"
# Deploy with secret
gcloud run deploy SERVICE --source . --region REGION --allow-unauthenticated \
--set-secrets "MY_SECRET=MY_SECRET:latest"Useful Commands
# Stream logs
gcloud run services logs tail SERVICE --region REGION
# List services
gcloud run services list --region REGION
# Get service URL
gcloud run services describe SERVICE --region REGION --format "value(status.url)"
# Delete service
gcloud run services delete SERVICE --region REGIONCI/Headless Auth
gcloud auth activate-service-account --key-file=key.json
gcloud config set project PROJECT_IDTroubleshooting
| Issue | Fix |
|---|---|
| Build fails | Check Dockerfile locally: docker build. |
| 403 on deploy | Need roles/run.admin and roles/cloudbuild.builds.editor |
| App crashes on start | Check logs: gcloud run services logs tail SERVICE --region REGION |
| Port mismatch | Set --port to match app, or have app read PORT env var |
| Cold start slow | Set --min-instances 1 (stays warm, costs more) |
| Timeout on long requests | Increase with --timeout 300 (max 3600s) |
