Question

需要一點幫助來解決我在構建 ASP.NET 項目時遇到的問題，該項目引用 docker 容器內的本地 class 庫。

我在用着：

• ASP.NET 6.0
• Docker 版本 20.10.21，構建 baeda1f
• do.net sdk 6.0

當我嘗試運行docker build.

我收到以下錯誤：

我正在使用的dockerfile

關於我讓dockerfile獲取構建中的 package .dll有什么想法嗎？ 還是 go 關於獲得我想要的東西的錯誤方式？

我願意在 nuget 上托管 package，但目前這個dockerfile僅用於開發目的。

請記住，package 在本地的正確位置，因為使用以下方法構建項目：

do.net build ProjectName.csproj

工作正常

PS 我用“PackageName”替換了 package 名稱，用“ProjectName”替換了項目名稱。

我嘗試為 ASP.NET 6.0 構建 dockerfile，我希望它能通過，但我得到了一個錯誤。

Answer 1

所以我幾乎立即解決了這個問題，我將 class 庫構建到我的 asp.net 項目所在的位置，清除了 docker 緩存，然后再次構建。

Answer 2

Id項目位於您的計算機上，您需要在定義后復制xxx.dll

SWORKDIR /src COPY ["Xxx.csproj", "."] COPY ["output/Debug.net6.0/xxx.dll", "."]

否則你必須創建 nuget package dll 然后你從 nuget 安裝
