【问题描述】：
我正在尝试为它的这个示例项目结构创建一个 docker 映像，如下所示
- 两个模块 - common 和 go-modules
以下是我的 Docker 文件
FROM golang as builder
ENV GO111MODULE=on
WORKDIR /go-modules-docker
COPY . .
COPY ./go-modules/go.mod .
COPY ./go-modules/go.sum .
RUN go mod download
RUN CGO_ENABLED=0 GOOS=linux go build -o app ./go-modules/main.go
FROM alpine:3.8
WORKDIR /root/
COPY --from=builder /go-modules/app .
CMD ["./app"]
go.mod文件如下
module go-modules
go 1.15
replace common => /go-modules-docker/common
require (
common v0.0.0-00010101000000-000000000000
github.com/julienschmidt/httprouter v1.3.0
)
Main.go如下
package main
import (
"fmt"
"log"
"net/http"
"go-modules/greet" // go-modules is our project namespace
"common/deps"
"github.com/julienschmidt/httprouter"
)
func main() {
r := httprouter.New()
r.GET("/", func(w http.ResponseWriter, r *http.Request, _ httprouter.Params) {
fmt.Fprintf(w, "hello world, v%v %v", greet.Version, deps.Version2)
})
log.Println("listening to port *:8080. press ctrl + c to cancel.")
log.Fatal(http.ListenAndServe(":8080", r))
}
从父目录运行此命令时 - go-modules-docker
docker build -t go-mod-docker -f go-modules/Dockerfile .
我收到以下错误

谁能建议可以做什么以及如何解决这个问题？
【问题讨论】：
-
它是打印出您附加的图像文件，还是一些文本格式错误？你能用错误消息的实际文本替换屏幕截图吗？
-
请不要发布文字图片。您正在使用单个文件名运行
go build，它不会使用模块。使用模块内的包运行go build。 -
@DavidMaze 已编辑问题以用错误文本替换错误图像。
-
@JimB 正如您所提到的，我认为问题在于构建命令是从模块外部运行的。由于它是一个多模块并且在主模块中使用了公共模块。我必须从模块外部运行构建命令（复制 Dockerfile 中的公共文件夹）。
