无法从外部docker连接到dockerized redis实例
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。 你能告诉我在这里做错了吗？
创build了docker，映射端口6379到127.0.0.1:6379
bash-3.2$ docker run -p 127.0.0.1:6379:6379 --name webmonitor-redis -d redis 3291541d58ab16c362f9e0cd7017d179c0bc9aef3a1323e79f1e1ca075e171c9 dockerps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（但容器运行在同一主机）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
它工作，如果我尝试从另一个容器连接虽然..
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>
这里是docker检查容器：
bash-3.2$ docker inspect 3291541d58ab [ { "Id": "3291541d58ab16c362f9e0cd7017d179c0bc9aef3a1323e79f1e1ca075e171c9", "Created": "2015-10-03T15:48:17.818355794Z", "Path": "/entrypoint.sh", "Args": [ "redis-server" ], "State": { "Running": true, "Paused": false, "Restarting": false, "OOMKilled": false, "Dead": false, "Pid": 7769, "ExitCode": 0, "Error": "", "StartedAt": "2015-10-03T15:48:17.954436198Z", "FinishedAt": "0001-01-01T00:00:00Z" }, "Image": "2f2578ff984f013c9a5d6cbb6fe061ed3f73a17380a4c9b53b76d4b8da3eda7d", "NetworkSettings": { "Bridge": "", "EndpointID": "b787e46d1219f36d4f1b1ea35c5f750f7174221137fb01889a26a3bc1e1c6aee", "Gateway": "172.17.42.1", "GlobalIPv6Address": "", "GlobalIPv6PrefixLen": 0, "HairpinMode": false, "IPAddress": "172.17.0.8", "IPPrefixLen": 16, "IPv6Gateway": "", "LinkLocalIPv6Address": "", "LinkLocalIPv6PrefixLen": 0, "MacAddress": "02:42:ac:11:00:08", "NetworkID": "30176c9c7c14a6a052af784014832a0c52b5966089d7bcfe535041569e6bb1c9", "PortMapping": null, "Ports": { "6379/tcp": [ { "HostIp": "127.0.0.1", "HostPort": "6379" } ] }, "SandboxKey": "/var/run/docker/netns/3291541d58ab", "SecondaryIPAddresses": null, "SecondaryIPv6Addresses": null }, "ResolvConfPath": "/mnt/sda1/var/lib/docker/containers/3291541d58ab16c362f9e0cd7017d179c0bc9aef3a1323e79f1e1ca075e171c9/resolv.conf", "HostnamePath": "/mnt/sda1/var/lib/docker/containers/3291541d58ab16c362f9e0cd7017d179c0bc9aef3a1323e79f1e1ca075e171c9/hostname", "HostsPath": "/mnt/sda1/var/lib/docker/containers/3291541d58ab16c362f9e0cd7017d179c0bc9aef3a1323e79f1e1ca075e171c9/hosts", "LogPath": "/mnt/sda1/var/lib/docker/containers/3291541d58ab16c362f9e0cd7017d179c0bc9aef3a1323e79f1e1ca075e171c9/3291541d58ab16c362f9e0cd7017d179c0bc9aef3a1323e79f1e1ca075e171c9-json.log", "Name": "/webmonitor-redis", "RestartCount": 0, "Driver": "aufs", "ExecDriver": "native-0.2", "MountLabel": "", "ProcessLabel": "", "AppArmorProfile": "", "ExecIDs": null, "HostConfig": { "Binds": null, "ContainerIDFile": "", "LxcConf": [], "Memory": 0, "MemorySwap": 0, "CpuShares": 0, "CpuPeriod": 0, "CpusetCpus": "", "CpusetMems": "", "CpuQuota": 0, "BlkioWeight": 0, "OomKillDisable": false, "MemorySwappiness": -1, "Privileged": false, "PortBindings": { "6379/tcp": [ { "HostIp": "127.0.0.1", "HostPort": "6379" } ] }, "Links": null, "PublishAllPorts": false, "Dns": null, "DnsSearch": null, "ExtraHosts": null, "VolumesFrom": null, "Devices": [], "NetworkMode": "default", "IpcMode": "", "PidMode": "", "UTSMode": "", "CapAdd": null, "CapDrop": null, "GroupAdd": null, "RestartPolicy": { "Name": "no", "MaximumRetryCount": 0 }, "SecurityOpt": null, "ReadonlyRootfs": false, "Ulimits": null, "LogConfig": { "Type": "json-file", "Config": {} }, "CgroupParent": "", "ConsoleSize": [ 0, 0 ] }, "GraphDriver": { "Name": "aufs", "Data": null }, "Mounts": [ { "Name": "643a80cbd7a50cfd481acc48721b34030c8ce55ba64ac3bc161d5b330c9374d2", "Source": "/mnt/sda1/var/lib/docker/volumes/643a80cbd7a50cfd481acc48721b34030c8ce55ba64ac3bc161d5b330c9374d2/_data", "Destination": "/data", "Driver": "local", "Mode": "", "RW": true } ], "Config": { "Hostname": "3291541d58ab", "Domainname": "", "User": "", "AttachStdin": false, "AttachStdout": false, "AttachStderr": false, "ExposedPorts": { "6379/tcp": {} }, "PublishService": "", "Tty": false, "OpenStdin": false, "StdinOnce": false, "Env": [ "PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin", "REDIS_VERSION=3.0.3", "REDIS_DOWNLOAD_URL=http://download.redis.io/releases/redis-3.0.3.tar.gz", "REDIS_DOWNLOAD_SHA1=0e2d7707327986ae652df717059354b358b83358" ], "Cmd": [ "redis-server" ], "Image": "redis", "Volumes": { "/data": {} }, "VolumeDriver": "", "WorkingDir": "/data", "Entrypoint": [ "/entrypoint.sh" ], "NetworkDisabled": false, "MacAddress": "", "OnBuild": null, "Labels": {} } } ]
我在这里错过了什么？
确保主机上的端口6379被转发到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
虚拟机有自己的IP 192.168.99.100所以我可以通过绑定连接到192.168.99.100:6379:6379，然后连接如下。
0c4de9a25467:redis-stable electron$ ./src/redis-cli -h 192.168.99.100 192.168.99.100:6379>
docker run -p 6379:6379 -host 0.0.0.0 --name webmonitor-redis -d redis
