C# 连接被拒绝-ASP.Net Core 2.1中数据保护密钥的Redis

我正在浏览Microsoft的这篇文章：

我正在努力做到以下几点：

    services.AddDataProtection()
        .PersistKeysToRedis(ConnectionMultiplexer.Connect("localhost"));

错误堆栈：

我正在使用Docker：

redis:
    image: redis:alpine
    container_name: redis
    ports:
      - "6379:6379"

---

有什么想法吗？

您需要参考集装箱和港口

services.AddDataProtection()
        .PersistKeysToRedis(ConnectionMultiplexer.Connect("redis:6379"));

我还在配置中添加了abortConnect=false

REDIS_CONNECTION_STRING = "redis:6379,abortConnect=false"


var redis = ConnectionMultiplexer.Connect(Environment.GetEnvironmentVariable("REDIS_CONNECTION_STRING"));
services.AddDataProtection().PersistKeysToRedis(redis, "DataProtection-Keys");
