docker - Docker群节点失败 'non-zero exit'

Question

我正在研究一个入门示例，但是在尝试将镜像部署到群集时遇到了问题。具体来说，所有节点最终都失败，并显示以下错误消息:

"task: non-zero exit (2147516553)"

该图像在单个容器中加载时可以工作-但不会成群运行。

dockerfile:

FROM microsoft/aspnetcore-build:2.0 AS build-env
WORKDIR /app

COPY *.csproj ./
RUN dotnet restore

COPY . ./
RUN dotnet publish -c Release -o out

FROM microsoft/aspnetcore:2.0
WORKDIR /app
COPY --from=build-env /app/out .

ENTRYPOINT ["dotnet", "dotNetCore.dll"]

docker-compose.yml:

version: "3"
services:
  web:
    image: [repo]/get-started
    deploy:
      replicas: 5
      resources:
        limits:
          memory: 50M
      restart_policy:
        condition: on-failure
    ports:
      - "8080:5000"
    networks:
      - webnet
networks:
  webnet:

看起来所有节点都正常启动(进入运行状态)。但是然后失败并显示错误消息。

50Mb的内存限制对于您的服务而言绝对太低
