我是 golang 新手，我想构建我的第一个简单的 Web 应用程序。每次我想构建源代码时，都会收到错误locale import "./controllers" in non-local package".
这是我的文件夹结构：
goTest
├── Dockerfile
├── controllers
│ └── IndexController.go
└── main.go
The main.go file:
package main
import (
"github.com/julienschmidt/httprouter"
"net/http"
"log"
"./controllers"
)
func main() {
router := httprouter.New()
router.GET("/", IndexController)
log.Fatal(http.ListenAndServe(":8080", router))
}
The IndexController.go file:
package controllers
import (
"fmt"
)
func IndexController(w http.ResponseWriter, r *http.Request, ps httprouter.Params) error {
fmt.Fprintf(w, "Hi %s!", r.URL.Path[1:])
}
My Dockerfile文件（复制自https://hub.docker.com/_/golang/ https://hub.docker.com/_/golang/):
FROM golang:1.8
WORKDIR /go/src/app
COPY . .
RUN go-wrapper download # "go get -d -v ./..."
RUN go-wrapper install # "go install -v ./..."
EXPOSE 8080
CMD ["app"]
docker 和 go 构建命令：
docker build -t my-golang-app .
至少控制台输出：
Sending build context to Docker daemon 4.608kB
