goland远程调试k8s上容器的实现

# 选用go1.19的alpine版本
FROM golang:1.19-alpine
# 设置go代理并下载dlv源码并编译安装
RUN go env -w GOPROXY="https://goproxy.cn,direct" && go mod download github.com/go-delve/delve@v1.9.1
WORKDIR /go/pkg/mod/github.com/go-delve/delve@v1.9.1/
RUN go mod tidy 
RUN go mod vendor
RUN go install ./cmd/dlv/
# 替换源并下载gcc，非必须，看编译是否依赖
RUN sed -i 's/dl-cdn.alpinelinux.org/mirrors.aliyun.com/g' /etc/apk/repositories
RUN apk --no-cache add gcc
