Dockerfile：计算缓存键失败：“/nginx.conf”未找到：未找到

Question

我正在开发一个 Blazor Wasm（ASP.Net 核心托管，由通常的 3 个项目客户端、服务器和共享组成）应用程序，我想使用 [=22= 将其部署到 Linux ]. 我正在将 nginx.conf 文件复制到服务器项目根文件夹，但在尝试发布到 Azure 应用服务容器时，我得到：

failed to compute cache key: "/nginx.conf" not found: not found

这是我的 Dockerfile：

FROM mcr.microsoft.com/dotnet/aspnet:3.1 AS base
WORKDIR /app
EXPOSE 80
EXPOSE 443

FROM mcr.microsoft.com/dotnet/sdk:3.1 AS build
WORKDIR /src
COPY ["MyLocalShop/Server/MyLocalShop.Server.csproj", "MyLocalShop/Server/"]
COPY ["MyLocalShop.Services.MongoDb/MyLocalShop.Services.MongoDb.csproj", "MyLocalShop.Services.MongoDb/"]
COPY ["MyLocalShop.Server.Contracts/MyLocalShop.Server.Contracts.csproj", "MyLocalShop.Server.Contracts/"]
COPY ["MyLocalShop/Shared/MyLocalShop.Shared.csproj", "MyLocalShop/Shared/"]
COPY ["MyLocalShop/Client/MyLocalShop.Client.csproj", "MyLocalShop/Client/"]
RUN dotnet restore "MyLocalShop/Server/MyLocalShop.Server.csproj"
COPY . .
WORKDIR "/src/MyLocalShop/Server"
RUN dotnet build "MyLocalShop.Server.csproj" -c Release -o /app/build

FROM build AS publish
RUN dotnet publish "MyLocalShop.Server.csproj" -c Release -o /app/publish

FROM nginx:alpine AS final
WORKDIR /app
COPY --from=publish /app/publish .
COPY nginx.conf /etc/nginx/nginx.conf
ENTRYPOINT ["dotnet", "MyLocalShop.Server.dll"]

如果我运行 dotnet publish 命令检查 app/publish 中的输出目录，我可以看到该文件确实存在。我错过了什么？

Answer 1

当您要复制的文件也在 .dockerignore

中时，可能会发生这种情况

Answer 2

可能你的项目中缺少nginx.conf文件。

Answer 3

您是否将 docker 构建的上下文设置为包含 nginx.conf 的目录而不是其下方的目录？

例如 nginx.conf |-MyLocalShop

不好：docker build -t something:latest -f ./DockerFile ./MyLocalShop

好：docker build -t something:latest -f ./DockerFile .
