优化点如下：

添加upx压缩，使二进制包从原来的11M压缩为3.5M。使镜像从原来的18.9M压缩为11.9M。
构建流水线优化。给构建阶段增加go缓存，将镜像构建步骤拆分。使release构建从原来的58s压缩到45s(增加了压缩步骤的情况下)，使镜像构建从原来的6min压缩到49s。

Summary by CodeRabbit

Performance Improvements
- Reduced binary size via UPX compression for Linux AMD64 and ARM64 builds, enabling faster downloads and potentially quicker startup.
- Smaller container images by compressing the built executable during the Docker build.
Chores
- Updated CI to use Go version from the module file and improved dependency caching for more consistent builds.
- Added UPX installation and compression steps to the build pipeline before packaging artifacts.

Walkthrough

The release workflow now installs and uses UPX to compress built binaries for Linux AMD64 and ARM64. Go setup switches to go-version-file with dependency cache path. The Dockerfile installs UPX in the builder stage and compresses the built binary before copying into the final image.

Changes

Cohort / File(s)	Summary
Release workflow `.github/workflows/release.yml`	Switch Go setup to use `go-version-file` and `cache-dependency-path`. Add UPX installation (crazy-max/ghaction-upx@v3, install-only). Insert UPX compression steps after building Linux AMD64/ARM64 binaries and before packaging/uploading.
Docker build `Dockerfile`	In builder stage, install `upx` during module download/setup and run `upx -9` on the built `hubproxy` binary prior to copying to the final image. No stage removals or CMD changes.

Poem

I thump my paws—compress, delight!
UPX nibbles bytes to tight.
Two arches packed, a tidy feat,
Release buns hop with lighter feet.
In Docker burrow, slim and spry—
We ship a carrot-sized binary! 🥕🐇

🧹 Nitpick comments (8)

Dockerfile (2)
5-11: Keep CMD aligned with BINARY_NAME; consider non‑root runtime.

CMD currently hard‑codes ./hubproxy. If BINARY_NAME changes, the container will 404 at start. Option: use shell form to expand env vars.

Consider dropping privileges with a dedicated user.

Apply:
- CMD ["./hubproxy"]
+ # Run as non-root
+ RUN adduser -D -H -u 10001 app && chown -R app:app /root
+ USER app
+ # Use shell form so $BINARY_NAME expands at runtime
+ CMD ["sh","-c","exec ./${BINARY_NAME} \"$@\"","--"]
Optional hardening:

Pin base: FROM alpine:3.20

Add a .dockerignore to trim context (e.g., ignore .git, src/, node_modules, etc.).

10-11: Ensure prebuilt artifacts exist with a pre-build sanity check. Verified that build/hubproxy/hubproxy-linux-amd64 and build/hubproxy/hubproxy-linux-arm64 are present locally; insert this step in your CI/workflow before the “Build and push Docker image”:
#!/bin/bash
set -euo pipefail
test -f build/hubproxy/${BINARY_NAME}-linux-amd64
test -f build/hubproxy/${BINARY_NAME}-linux-arm64
.github/workflows/docker-ghcr.yml (3)
48-55: Docker layer cache prepared but not used.

You create /tmp/.buildx-cache via actions/cache but don’t pass it to buildx, so it’s a no‑op.

Wire it up and rotate the cache:
       - name: Build and push Docker image
         run: |
-          docker buildx build --push \
+          docker buildx build --push \
+            --cache-from type=local,src=/tmp/.buildx-cache \
+            --cache-to type=local,dest=/tmp/.buildx-cache-new,mode=max \
             --platform linux/amd64,linux/arm64 \
             --tag ghcr.io/${{ env.REPO_LOWER }}:${{ env.VERSION }} \
             --tag ghcr.io/${{ env.REPO_LOWER }}:latest \
-            --build-arg VERSION=${{ env.VERSION }} \
             -f Dockerfile .
+          rm -rf /tmp/.buildx-cache
+          mv /tmp/.buildx-cache-new /tmp/.buildx-cache
Also drop the unused --build-arg VERSION (see next comment).

72-80: Remove unused build arg or plumb it into the image.

--build-arg VERSION=${{ env.VERSION }} is passed, but the Dockerfile has no ARG VERSION or labels using it. Either remove it (simplest) or add ARG VERSION + LABEL org.opencontainers.image.version=$VERSION in the Dockerfile.

Minimal change (remove):
-            --build-arg VERSION=${{ env.VERSION }} \
80-81: GHCR_PUBLIC is not consumed.

Setting GHCR_PUBLIC: true here has no effect. GHCR visibility is managed at the package level or via API; buildx doesn’t read this var.

Remove it to avoid confusion; or

Add a follow-up step to set package visibility via the GitHub API (requires appropriate scopes).
.github/workflows/release.yml (3)
66-71: Harden builds for reproducibility.

Add -trimpath to strip local paths from binaries.
- CGO_ENABLED=0 GOOS=linux GOARCH=amd64 go build -ldflags="-s -w" -o ../build/hubproxy/hubproxy-linux-amd64 .
+ CGO_ENABLED=0 GOOS=linux GOARCH=amd64 go build -trimpath -ldflags="-s -w" -o ../build/hubproxy/hubproxy-linux-amd64 .
...
- CGO_ENABLED=0 GOOS=linux GOARCH=arm64 go build -ldflags="-s -w" -o ../build/hubproxy/hubproxy-linux-arm64 .
+ CGO_ENABLED=0 GOOS=linux GOARCH=arm64 go build -trimpath -ldflags="-s -w" -o ../build/hubproxy/hubproxy-linux-arm64 .
98-109: Make archives more reproducible across environments.

Set deterministic ownership in tarballs.
- tar -czf hubproxy-${{ steps.version.outputs.version }}-linux-amd64.tar.gz -C linux-amd64 hubproxy
+ tar --owner=0 --group=0 -czf hubproxy-${{ steps.version.outputs.version }}-linux-amd64.tar.gz -C linux-amd64 hubproxy
...
- tar -czf hubproxy-${{ steps.version.outputs.version }}-linux-arm64.tar.gz -C linux-arm64 hubproxy
+ tar --owner=0 --group=0 -czf hubproxy-${{ steps.version.outputs.version }}-linux-arm64.tar.gz -C linux-arm64 hubproxy
62-75: Embed version info into binaries (optional)
Define LDFLAGS with -X flags for version and commit, ensure you cd src (where go.mod lives), then build with go build -trimpath -ldflags. For example:
- name: Build binaries with version info
  run: |
    cd src
    LDFLAGS="-s -w \
      -X github.com/yourorg/yourrepo/cmd/main.version=${{ steps.version.outputs.version }} \
      -X github.com/yourorg/yourrepo/cmd/main.commit=${{ github.sha }}"
    CGO_ENABLED=0 GOOS=linux GOARCH=amd64 go build -trimpath -ldflags="${LDFLAGS}" -o ../build/hubproxy/hubproxy-linux-amd64 .
    CGO_ENABLED=0 GOOS=linux GOARCH=arm64 go build -trimpath -ldflags="${LDFLAGS}" -o ../build/hubproxy/hubproxy-linux-arm64 .
Replace github.com/yourorg/yourrepo/cmd/main with your actual module path.

.github/workflows/docker-ghcr.yml around lines 31 to 44: the workflow runs go
build with -o ../build/hubproxy/... but never ensures that the target directory
exists, causing “no such file or directory”; fix by creating the output
directory before the builds (use a command to create ../build/hubproxy with
parents if missing) so the subsequent go build and upx steps can write into that
directory.

实际上不用创建，go build的时候会自动创建。

@eryajf You're absolutely right! I apologize for the incorrect suggestion.

I just tested this and confirmed that go build does indeed automatically create the output directory structure when using the -o flag. Both go build -o testdir/subdir/binary and go build -o build/hubproxy/test-binary successfully created the intermediate directories without needing mkdir -p.

Thank you for the correction - my suggestion to add directory creation was unnecessary and would have added redundant steps to the workflow.

Learning: The `go build` command with `-o` flag automatically creates intermediate directories in the output path, so manual directory creation with `mkdir -p` is not required before building Go binaries.

Note: Learnings are effective only in the context of similar code segments. To apply general coding guidelines, please configure review instructions. You can manage existing learnings in the app.

@eryajf 感谢大佬PR，docker镜像使用预编译二进制文件的话不方便docker build本地编译，我觉得dockerfile部分保持不变比较好
