连接被拒绝 - 用于 ASP.Net Core 2.1 中的数据保护密钥的 Redis

Question

I'm going through this article from Microsoft: https://docs.microsoft.com/en-us/aspnet/core/security/data-protection/implementation/key-storage-providers?view=aspnetcore-2.1

I am trying to do the following:

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

Error Stack:

app    | Unhandled Exception: System.AggregateException: One or more errors occurred. (Connection refused) ---> System.Net.Sockets.SocketException: Connection refused

I am using Docker:

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

Any ideas?

Answer 1

You need to reference the container and port

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

I also added abortConnect=false" to configuration

REDIS_CONNECTION_STRING = "redis:6379,abortConnect=false"


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