Dockerfile golang Generator

The Go Dockerfile Generator creates hyper-optimized, distroless container images for Go microservices. It forces CGO_ENABLED=0 compilation flags to guarantee absolute portability across cloud environments.

Loading editor...

Micro Containers

Outputs images under 15MB using FROM scratch or alpine.

Static Linking

Disables CGO to prevent missing shared library errors at runtime.

How it Works

1

Go Version - Define your target golang compiler version.

2

Static Compilation - Toggle CGO dependencies.

3

Export Configuration - Generate the ultra-minimal Dockerfile.

Best Practices

Go containers leverage pure static linking to run within completely barren OS environments.

Compilation

go build .

CGO_ENABLED=0 GOOS=linux go build

Base Image

golang:1.21

scratch or alpine

Image Size

800MB+

< 20MB

Example Output

Here is a real generated snippet matching the production best practices above:

FROM golang:1.21-alpine AS builder
WORKDIR /app
COPY go.mod go.sum ./
RUN go mod download
COPY . .
RUN CGO_ENABLED=0 GOOS=linux go build -a -installsuffix cgo -o main .

FROM alpine:latest
WORKDIR /app
COPY --from=builder /app/main .
EXPOSE 8080
CMD ["./main"]

Advanced Configuration Logic

Go is unique because it compiles down to a single, static binary. It does not require a runtime environment like the JVM or Node.js to execute. Therefore, shipping a full Ubuntu or Debian image just to run a Go binary is a massive security and performance anti-pattern. We enforce a multi-stage build that compiles the binary in a heavy golang image, and then copies it into an empty 'scratch' or 'alpine' image.
