【问题描述】：

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

连接了端口 6379 后似乎可以正常启动：

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

我正在尝试使用以下代码进行连接：

        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

Linux 防火墙设置：

sudo iptables -L
Chain INPUT (policy ACCEPT)
target     prot opt source               destination

ACCEPT     all  --  anywhere             anywhere

Chain OUTPUT (policy ACCEPT)

我错过了什么？

【参考方案1】：

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”修复了问题：

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