我是 Kubernetes 新手。

所以我有我构建的这个 .NET Core 控制台应用程序 Docker 映像：

FROM mcr.microsoft.com/dotnet/core/runtime:3.0-buster-slim AS base
WORKDIR /app

FROM mcr.microsoft.com/dotnet/core/sdk:3.0-buster AS build
WORKDIR /src
COPY ["DataSync.Entry/DataSync.Entry.csproj", "DataSync.Entry/"]
RUN dotnet restore "DataSync.Entry/DataSync.Entry.csproj"
COPY . .
WORKDIR "/src/DataSync.Entry"
RUN dotnet build "DataSync.Entry.csproj" -c Release -o /app/build

FROM build AS publish
RUN dotnet publish "DataSync.Entry.csproj" -c Release -o /app/publish

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

此图像在我的机器上完美运行。但是，当我尝试将其部署为 Kubernetes 中的 CronJob 时，它失败了。

这是 YAML：

apiVersion: batch/v1beta1
kind: CronJob
metadata:
  name: netcore-cronjob
  namespace: aim-ns
  labels:
    app: netcore-cronjob
spec:
  schedule: "*/2 * * * *"
  jobTemplate:
    spec: #JOB
      backoffLimit: 1
      template: 
        spec: #POD
          containers:
            - name: netcore-job
              image: <ACR>.azurecr.io/aim/test-data-sync-netcore:v1 #my docker image above pushed to ACR
              command: ["dotnet", "DataSync.Entry.dll"]
              args: []
              resources:
                requests:
                  memory: "64Mi"
                  cpu: "100m"
                limits:
                  memory: "128Mi"
                  cpu: "150m"
          restartPolicy: Never

我在查看 Pod 上的日志时得到的错误消息：

NAME                                        READY   STATUS    RESTARTS   AGE
netcore-cronjob-1582854120-scwfb            0/1     Error     0          19s

当我跑步时，kubectl logs -n aim-ns netcore-cronjob-1582854120-scwfb我得到：

  It was not possible to find any installed .NET Core SDKs
  Did you mean to run .NET Core SDK commands? Install a .NET Core SDK from:
      https://aka.ms/dotnet-download

我在这里想念什么？

我遇到了同样的问题，我需要将“FROM mcr.microsoft.com/dotnet/core/runtime:3.0-buster-slim AS base”（用于运行应用程序）更改为“FROM mcr.microsoft。 com/dotnet/core/sdk:3.0-buster AS 基础”。我认为运行时间必须足够，但是......
