我有一個用go和gin寫的應用程序，這個檔案分割如下：
main.go
controller
controllers.go
database
database.go
middleware
middleware.go
models
models.go
routes
routes.go
go.mod
go.sum
dockerfile在每個資料夾中，我都有一個呼叫另一個套件的套件，例如：
package controller
import (
"log"
"net/http"
"os"
gomail "gopkg.in/mail.v2"
"github.com/dgrijalva/jwt-go"
"github.com/gin-gonic/gin"
models "github.com/guilherm5/login-user/models"
)
package routes
import (
"github.com/gin-gonic/gin"
controller "github.com/guilherm5/login-user/controller"
middleware "github.com/guilherm5/login-user/middleware"
)我的 go.mod 是這樣的：
module github.com/guilherm5/login-user
go 1.20
require (

github.com/gin-gonic/gin v1.9.0

)所以它遵循我的應用程式流程..
我想製作這個應用程式的 docker 映像（出於學習目的，我想學習 docker 的基礎知識，所以我製作了這個 api 進行測試）
docker 映像：
from golang:1.20 as build workdir /mail copy go.sum ./ copy go.mod ./ copy main.go ./ run go mod download run go build -o /appmail from gcr.io/distroless/base-debian10 workdir / copy --from=build /mail /mail expose 4000/ user nonroot:nonroot entrypoint ["/appmail"]
嘗試建立映像時出現錯誤：
=> error [build 7/7] run go build -o /appmail 0.7s ------ > [build 7/7] run go build -o /appmail: #13 0.680 main.go:5:2: no required module provides package github.com/guilherm5/login-user/routes; to add it: #13 0.680 go get github.com/guilherm5/login-user/routes ------ executor failed running [/bin/sh -c go build -o /appmail]: exit code: 1
有人知道為什麼嗎？我真的不知道該怎麼解決這個問題，如何將我的套件匯入到 docker 映像中？
--編輯
我按照建議更新了我的 dockerfile：
from golang:1.20 as build workdir /mail copy go.sum ./ copy go.mod ./ copy main.go ./ run go mod tidy run go mod download run go build -o /appmail from gcr.io/distroless/base-debian10 workdir / copy --from=build /mail /mail expose 4000/ user nonroot:nonroot entrypoint ["/appmail"]
錯誤：
github.com/guilherm5/login-user imports #12 9.121 github.com/guilherm5/login-user/routes: cannot find module providing package github.com/guilherm5/login-user/routes: module github.com/guilherm5/login-user/routes: git ls-remote -q origin in /go/pkg/mod/cache/vcs/a7be81f5c5695c6941aa1b7f5a49aa0800b2d648c4d72609eb5feae6f51cf505: exit status 128: #12 9.121 fatal: could not read Username for 'https://github.com': terminal prompts disabled #12 9.121 Confirm the import path was entered correctly. #12 9.121 If this is a private repository, see https://golang.org/doc/faq#git_https for additional information. ------ executor failed running [/bin/sh -c go mod tidy]: exit code: 1
問題發生在 copy main.go ./ this 上。
golang 將如何查看依賴項/套件？
models 的目錄是否存在。）在您的情況下，您的專案模組根目錄中已經有套件（目錄），但僅將 main.go 複製到容器系統。
因此，當 go mod tidy 運行時，它無法在快取或根目錄中看到套件。然後它嘗試從遠端拉取它。
我在遠端倉庫中有程式碼，那麼為什麼它沒有拉動？ 因為存儲庫是私有的。
解決方案
將所有檔案和資料夾複製到容器系統
copy . .
問題將會解決。您已經有了多階段構建，其中只有最終生產構建中必需的文件。
