Employ Multi-Stage Builds
Multi-stage builds allow you to use intermediate images and copy only the necessary artifacts into the final image.
Example for a Go Application:
# Build Stage
FROM golang:1.16-alpine AS builder
WORKDIR /app
COPY . .
RUN go build -o myapp
# Final Image
FROM alpine:latest
WORKDIR /app
COPY --from=builder /app/myapp .
CMD ["./myapp"]12
