COPY . .

RUN go build -o hello .

FROM alpine:latest

WORKDIR /app

COPY --from=builder /app/hello /app

ENTRYPOINT ["./hello"]

构建镜像：

docker build -t hello .
docker run hello
>> sh: ./hello: not found #输出如下错误

重新编译，进入容器进行调试

/app # ./hello
>> sh: ./hello: not found
/app # ldd hello

/app # ls /lib64/ld-linux-x86-64.so.2

我们将文件创建出来

mkdir /lib64
ln -s /lib/libc.musl-x86_64.so.1 /lib64/ld-linux-x86-64.so.2

重新执行正常运行

./hello
