Redis Docker - 无法从C#客户端连接

Question

我是docker和redis的新手,我使用以下命令在docker上运行redis 3.0:

docker run --name redisDev -d redis

它似乎启动与端口6379连接正常:

docker ps
CONTAINER ID        IMAGE               COMMAND                CREATED             STATUS              PORTS               NAMES
b95c9402dd42        redis:3             "/entrypoint.sh redi   47 minutes ago      Up 47 minutes       6379/tcp            redisDev

我正在尝试连接以下代码:

        var sb = new StringBuilder();
        var tw = new StringWriter(sb);
        ConnectionMultiplexer redis;
        try
        {
            redis = ConnectionMultiplexer.Connect("vb-haproxy01.verify.local", tw);
        }
        catch (Exception ex)
        {
            //Console.WriteLine(ex.Message);
            tw.Flush();

            Console.WriteLine(sb.ToString());
            return;
        }

我收到以下错误:

vb-haproxy01.verify.local:6379

我错过了什么？

问题是主机上的端口6379没有将端口6379转发到docker.以下命令的"-p 6379:6379"修复了该问题:

docker run -d --name redisDev -p 6379:6379 redis
