这两个场景推荐使用 Docker。

以下是一个 Dockerfile 示例：

# 使用 1.14.15 镜像
FROM golang:1.14.15 as builder

# 下载 delve-1.6.1 源码到 当前项目，记得加到项目的 .gitignore
ADD delve-1.6.1 /go/delve
WORKDIR /go/delve/delve-1.6.1
# 开启代理编译安装 dlv
RUN https_proxy=http://192.168.31.2:1087 http_proxy=http://192.168.31.2:1087 \
 go install github.com/go-delve/delve/cmd/dlv

# 拷贝代码
COPY . /build
WORKDIR /build/web
# 开始编译
RUN https_proxy=http://192.168.31.2:1087 http_proxy=http://192.168.31.2:1087 \
	GO111MODULE=on GOPROXY="https://goproxy.cn,direct" \
	GOPRIVATE="codeup.aliyun.com" \
  go build -o bin/web \
    # 必须加上下面一行编译参数
		-gcflags "all=-N -l" \
    -tags=jsoniter,prototype main.go


FROM debian:buster

EXPOSE 8080 40001

WORKDIR /
COPY --from=builder /build/web /web
RUN ls /
COPY --from=builder /go/bin/dlv /web/
RUN ls /web
COPY --from=builder /build/web/bin/web /web/bin/web

WORKDIR /web

#ENTRYPOINT [ "/bookadv-cmd" ]
CMD ["/web/dlv", \

## 需要注意，如果使用项目自身的参数，需要加上 "--"，否则会认为是 dlv 的参数进而发生错误。
