我正试图为它的这个示例项目结构创建一个坞映像，如下所示
- 两个模块-公共模块和围棋模块
以下是我的码头文件
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文件如下所示
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如下所示
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))
}当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

通过再次更新WORKDIR ( Dockerfile )到go-modules (基本上是做一个CD更改目录)并构建整个模块，解决了问题。
将docker文件更改为此解决了问题。
FROM golang as builder
ENV GO111MODULE=on
WORKDIR /go-modules-docker
COPY . .
WORKDIR /go-modules-docker/go-modules
RUN go mod download
RUN CGO_ENABLED=0 GOOS=linux go build -o /go-modules-docker/app
FROM alpine:3.8
WORKDIR /root/
COPY --from=builder /go-modules-docker/app .
