The Cloud SQL Auth Proxy is a Go utility that provides secure, IAM-authorized, TLS 1.3-encrypted connections to Google Cloud SQL instances without manual certificate management. It runs as a local proxy sidecar or standalone binary and supports metrics, health checks, and automatic IAM database authentication.

Use cases

• connect securely to a Cloud SQL instance from my local machine
• proxy Cloud SQL connections with IAM authentication
• run Cloud SQL proxy as a sidecar in Kubernetes
• encrypt database traffic to Cloud SQL without managing TLS certificates
• connect to private IP Cloud SQL instance from a VM
• monitor Cloud SQL proxy with Prometheus metrics

When to choose

• you need secure access to Cloud SQL from outside GCP or from workloads without a language connector
• you want IAM-based access control and automatic mTLS for Cloud SQL
• you're running Cloud SQL workloads in Kubernetes or Compute Engine and need a sidecar proxy

When to avoid

• you use Go, Java, Python, or Node.js and prefer an in-process Cloud SQL language connector
• you need to configure network connectivity between your VM and the Cloud SQL instance - the proxy does not handle networking
• you rely on Unix domain sockets with MySQL 8.4 instances
