build Dockerfile with multi-stage ? It also supports ARM64

[opvexe]

this is my dockerfile for test.

But the mirror image is still huge, about 800M

FROM --platform=$BUILDPLATFORM golang:1.16 as builder
ENV TZ=Asia/Shanghai LANG="C.UTF-8"
ARG TARGETARCH
ARG TARGETOS

WORKDIR /workspace
# Copy the Go Modules manifests
COPY go.mod go.mod
COPY go.sum go.sum
ENV GO111MODULE=on
ENV GOPROXY=https://goproxy.io,direct

# Copy the go source
COPY query query

# Build
RUN CGO_ENABLED=1 GOOS=$TARGETOS GOARCH=$TARGETARCH go build --tags='json1' -a -o queryd query/cmd/main.go

FROM golang:1.16-buster
WORKDIR /
COPY --from=builder /workspace/queryd .
ENTRYPOINT ["/queryd"]

Thank you for the issue. I have no solution, so I need someone's help.

I tried to use this method, and this image typed out at 80M .. I'm still testing whether the ARM64 mirror works?
