Regional-HA Cloud SQL (PostgreSQL/MySQL) with private IP via Private Service
Access, automated backups, point-in-time recovery, read replicas and IAM
database auth — the PSA networking footgun solved for you. Works with
Terraform and OpenTofu (>= 1.6), Google provider >= 7.0, < 8.0.
Secure defaults:
- No public IP (
ipv4_enabled = false); private IP through a PSA peering the module can create for you (reserved range +servicenetworkingconnection) - TLS-only client connections (
ssl_mode = "ENCRYPTED_ONLY") deletion_protection = true- Regional HA (
availability_type = "REGIONAL"), daily backups + PITR (engine-aware: WAL on PostgreSQL, binlog on MySQL) - IAM database authentication on, with the engine-correct flag spelling
- On PostgreSQL, the four low-cost CIS-recommended log flags default to
on(log_checkpoints,log_connections,log_disconnections,log_lock_waits); yourdatabase_flagsentries override them
Requirements
- Terraform or OpenTofu
>= 1.6 hashicorp/google>= 7.0, < 8.0- APIs:
sqladmin.googleapis.com, plusservicenetworking.googleapis.comandcompute.googleapis.comwhen using private IP
Upgrade note (1.0.x)
create_private_service_accessnow defaults to false and must be set explicitly for private-IP deployments. The old default (truebehind aprivate_network != nulltest) made the resource count depend on an apply-time value, which broke any composition that creates the VPC and the instance in one apply (e.g. the GCP landing-zone stack). If you setprivate_networkand relied on the implicit PSA creation, addcreate_private_service_access = true.- PostgreSQL instances now get four low-cost CIS-recommended log flags by
default (
log_checkpoints,log_connections,log_disconnections,log_lock_waits). Database flag changes restart the instance; override any of them explicitly viadatabase_flags(buyer entries win the merge).
