What problem does it solve?

Go Docker patterns help Go developers produce lean, secure container images by combining multi-stage builds, static linking, and distroless runtimes, reducing image size and attack surface.

Core Features & Use Cases

  • Multi-stage Build Patterns: Create small, production-ready images by compiling in a builder stage and exporting a minimal runtime image.
  • CGO_ENABLED=0 / Static Binaries: Enable CGO_ENABLED=0 to produce fully static binaries that run reliably in distroless environments.
  • Go Build Metadata: Use ldflags and build args to inject version and build information for traceability.
  • Use Case: Deploy a Go API service with a minimal runtime image while preserving observability and security requirements.

Quick Start

Build a production Go image by applying the multi-stage Dockerfile pattern and building with CGO_ENABLED=0.

FAQPage Schema
How do I build small Docker images for Go applications?

Build small Docker images for Go by using multi-stage builds to compile the binary in a builder stage, then exporting a minimal runtime image using distroless containers. This pattern reduces image size and attack surface.

Why do I need CGO_ENABLED=0 when building Go containers with distroless images?

You need CGO_ENABLED=0 to produce fully static Go binaries that run reliably in distroless environments. Distroless images lack standard C libraries, so disabling CGO ensures your application executes correctly without runtime dependencies.

What is the best way to inject version metadata into a Go binary during a Docker build?

Inject version metadata into a Go binary during a Docker build by using ldflags and build args. This passes version and build information into the compilation process, ensuring traceability for deployed containers.

Does the multi-stage Dockerfile pattern support health checks and non-root users for Go services?

Yes, the multi-stage Dockerfile pattern supports health checks and non-root users for Go services. These security patterns are applied alongside static linking and distroless runtimes to create secure, production-ready containers.

Can I use distroless runtimes for Go API services that require observability?

Yes, you can deploy a Go API service with a minimal distroless runtime image while preserving observability and security requirements. The pattern combines static binaries with health checks and non-root user configurations.
