Building a docker image to run go applications
问题
我正在构建一个在 macOS（Monterrey）上的 Docker 镜像，使用以下 Dockerfile：
FROM golang:latest
WORKDIR /src
COPY go.* ./
RUN go mod download
COPY . /src
RUN go build -o /main
ENTRYPOINT ["/main"]
在第三行之前都正常工作，但在第四行时出现以下错误：
=> ERROR [4/6] RUN go mod download 0.2s
------
> [4/6] RUN go mod download:
#8 0.206 go mod download: no modules specified (see 'go help mod download')
------
executor failed running [/bin/sh -c go mod download]: exit code: 1
请问在下载依赖项时我做错了什么？

FROM golang:latest
WORKDIR /src
COPY go.* ./
RUN go mod download
COPY . /src
RUN go build -o /main
ENTRYPOINT ["/main"]
It works fine til the 3rd line and on the 4th it complains of
=> ERROR [4/6] RUN go mod download 0.2s
------
> [4/6] RUN go mod download:
#8 0.206 go mod download: no modules specified (see 'go help mod download')
------
executor failed running [/bin/sh -c go mod download]: exit code: 1
Any clues what I am doing wrong while the dependencies are being downloaded?

我在工作目录中缺少以下列出的几个文件。这些文件是下载依赖项所需的。
Dockerfile //这个文件已经在文件夹中了。
go.sum
go.mod
main.go
英文:
I was missing couple of files from the Working directory as listed below. These are needed to download the dependencies.
Dockerfile //this was already in the folder.
go.sum
go.mod
main.go

使用download命令时，需要指定要下载的包，而不是使用go mod tidy && go mod vendor命令。
英文:
Instead of using download do :
go mod tidy && go mod vendor
You need to specify which package to download when you use "mod download"
