Provider, Google Cloud (GCE)

GCP isn't natively supported by Daedalus. Use the Direct SSH path or the manual deploy.

Compute Engine VM

gcloud compute instances create olympus-prod \
  --zone=us-central1-a \
  --machine-type=e2-medium \
  --image-family=ubuntu-2204-lts \
  --image-project=ubuntu-os-cloud \
  --boot-disk-size=50GB \
  --tags=http-server,https-server

e2-medium (2 vCPU, 4GB RAM) costs ~$25/month with sustained-use discount.

Firewall

gcloud compute firewall-rules create allow-https \
  --allow tcp:443 \
  --target-tags=https-server

gcloud compute firewall-rules create allow-http \
  --allow tcp:80 \
  --target-tags=http-server

gcloud compute firewall-rules create allow-ssh-from-me \
  --allow tcp:22 \
  --source-ranges=$(curl -s ifconfig.me)/32

Block everything else by default.

Cloud SQL (managed Postgres)

Use Cloud SQL for Postgres if you want managed DB on GCP:

gcloud sql instances create olympus-db \
  --database-version=POSTGRES_17 \
  --tier=db-g1-small \
  --region=us-central1

Configure verify-full SSL, see Deploy, Database SSL verify-full.

IAM service accounts

For deployments managed via GitHub Actions to GCP, use a service account with the minimum permissions (Compute Instance Admin, Cloud SQL Client). Add the JSON key to GitHub Secrets as GCP_SA_KEY.

Cloud DNS

GCP's Cloud DNS works for the Olympus subdomain records. Or use your existing DNS provider.

Cost estimate

For ~1k MAU:

e2-medium VM: $25/mo
Cloud SQL db-g1-small: $13/mo
Egress (~10GB): ~$1
Total: ~$40/mo

Cheaper than equivalent AWS; pricier than DigitalOcean.
