Question

temp <- read_sheet(url, sheet = "DATA", range = cell_cols("A:N"), col_types = 'c')

我得到的错误是这个。因此，我一直在尝试为Golang应用程序首次编写Dockerfile，这就是我遇到的问题。

RUN mkdir /app
WORKDIR /app

# We want to populate the module cache based on the go.{mod,sum} files.
COPY go.mod .
COPY go.sum .

RUN go mod download

COPY . .

# Build the Go app
RUN go build -o ./out/go-sample-app .
RUN CGO_ENABLED=0 GOOS=linux GOARCH=amd64 go build -a -installsuffix cgo -o main app/server.go

# This container exposes port 8080 to the outside world
EXPOSE 8080

# Run the binary program produced by `go install`
CMD ["go", "run, "server.go"]

文件结构就像

Answer 1

@divan_cyph确保您正在运行docker。您可以通过从cli执行docker info进行检查。

旁注，只需在COPY . .调用上方添加go mod download，然后同时删除COPY go.mod .和COPY go.sum .

，就可以节省几行
