我有最新的docker安装（没有boot2docker），我无法连接到本地运行的dockerized redis实例。你能告诉我这里我做错了吗？
创建了docker，将端口6379映射到127.0.0.1:6379
bash-3.2$ docker run -p 127.0.0.1:6379:6379 --name webmonitor-redis -d redis
3291541d58ab16c362f9e0cd7017d179c0bc9aef3a1323e79f1e1ca075e171c9
docker ps输出：
bash-3.2$ docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
3291541d58ab redis "/entrypoint.sh redis" 14 seconds ago Up 6 seconds 127.0.0.1:6379->6379/tcp webmonitor-redis
尝试从外部容器（但运行容器的主机）连接，连接失败：
bash-3.2$ ./src/redis-cli
Could not connect to Redis at 127.0.0.1:6379: Connection refused
not connected> exit
如果我尝试从另一个容器连接，它可以工作..
bash-3.2$ docker run -it --link webmonitor-redis:redis --rm redis sh -c 'exec redis-cli -h "$REDIS_PORT_6379_TCP_ADDR" -p "$REDIS_PORT_6379_TCP_PORT"'
172.17.0.8:6379>
这是docker检查容器：
bash-3.2$ docker inspect 3291541d58ab

我在这里错过了什么吗？
答案 0 :(得分：8)
确保主机上的端口6379转发到docker上的端口6379
使用-p 6379:6379来解决问题：
docker run -d --name redisDev -p 6379:6379 redis
答案 1 :(得分：4)
虚拟机拥有自己的IP 192.168.99.100，因此我可以通过绑定到192.168.99.100:6379:6379进行连接，然后按以下方式连接。
0c4de9a25467:redis-stable electron$ ./src/redis-cli -h 192.168.99.100
192.168.99.100:6379>
答案 2 :(得分：-2)
docker run -p 6379:6379 -host 0.0.0.0 --name webmonitor-redis -d redis
