Question

我正在尝试在 docker 构建过程中嵌入测试构建，并在任一测试失败时中止它。我的 docker 文件如下所示：

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

FROM mcr.microsoft.com/dotnet/core/sdk:3.1-buster AS build
WORKDIR /src
COPY ["WebApplication1/WebApplication1.csproj", "WebApplication1/"]
COPY ["WebApplication1.Tests/WebApplication1.Tests.csproj", "WebApplication1.Tests/"]
RUN dotnet restore "WebApplication1/WebApplication1.csproj"
COPY . .
WORKDIR /src/WebApplication1
RUN dotnet build "WebApplication1.csproj" -c Release -o /app/build

FROM build AS test
WORKDIR /src/WebApplication1.Tests
RUN dotnet test --logger:trx

FROM build AS publish
WORKDIR /src/WebApplication1
RUN dotnet publish "WebApplication1.csproj" -c Release -o /app/publish

FROM base AS final
WORKDIR /app
COPY --from=publish /app/publish .
ENTRYPOINT ["dotnet", "WebApplication1.dll"]

有没有人知道如何处理它？谢谢你

Answer 1

Docker build 仅从您的 docker 文件生成 docker 镜像。它不运行它。

您需要在构建镜像后使用“docker run”才能将镜像作为容器实际启动（然后将执行您的入口点命令）

https://docs.docker.com/engine/reference/run/

Answer 2

您有一个多级 docker 文件，https://docs.docker.com/develop/develop-images/multistage-build/

对于您的情况，这将起作用

docker build --target test -t test-tag .
docker build -t webapp-image .
docker run -ti test-tag # will run tests and give you results

如果你想看到其他阶段的输出，你需要做同样的事情

Docker 镜像拒绝运行 dotnet test 命令
