.Net Core与EC2教程中的Docker问题
我正在通过本教程尝试在EC2容器服务上安装一个简单的ASP.Net核心应用程序。 我得到的结束，但不能让我的容器启动。 当我input：
docker run 171329494690.dkr.ecr.us-west-2.amazonaws.com/ecsdemo-redisgeo:latest 手动运行容器我得到以下错误：

任何帮助将不胜感激，我是AWS的新手，所以请让我知道，如果我可以提供任何更多的信息。
这是我的docker文件：
FROM microsoft/dotnet:1.1-sdk-projectjson COPY src /app WORKDIR /app RUN ["dotnet", "restore"] WORKDIR /app/RedisGeo RUN ["dotnet", "build"] EXPOSE 5000/tcp ENV ASPNETCORE_URLS https://*:5000 ENTRYPOINT ["dotnet", "run", "--server.urls", "http://*:5000"]
当我运行以下命令docker ps --format "{{.ID}}: {{.Status}} {{.Command}} {{.Ports}}"当前正在运行的docker容器
8285b5479401: Up 22 hours "/agent" ba110a5f14ef: Up 46 hours "/app/docker-entrypoi" 0.0.0.0:80->80/tcp, 443/tcp
ecsdemo-redisgeo任务容器定义
Connection refused 127.0.0.1:6379
此错误表示127.0.0.1:6379上没有可用的Redis服务器实例。
确保你的task-definition.json与ECS task-definition.json相同，其中包含${IMAGE_NAME}-redis容器定义，它将告诉ECS同时在你的App中部署一个Redis服务器的Docker实例。 您可以在redis-geo / scripts中find用于部署redis-geo App的脚本 。
redis服务器实例的主机名可以从REDIS_HOST环境variables中访问，您应该在应用程序中使用它，例如：
container.Register<IRedisClientsManager>(c => new RedisManagerPool(AppSettings.Get("REDIS_HOST", defaultValue:"localhost")));
当我尝试开发教程时遇到了同样的问题，经过几次尝试和失败之后，我终于通过从我的task-definition.json文件中删除以下条目来设法使其工作。
{ "name": "SERVICESTACK_LICENSE", "value": "${SERVICESTACK_LICENSE}" },
它失败的原因是因为我在travis中没有这个入口，所以我想它在这之后不能读取REDIS_HOST。
