现象
➜ ~ docker psCONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES3b45b6a8d0fc elasticsearch:latest "/bin/bash" 2 hours ago Up About an hour 0.0.0.0:9200->9200/tcp, 0.0.0.0:9300->9300/tcp ela-slave
端口是已经映射的
➜ ~ curl 127.0.0.1:9200curl: (52) Empty reply from server
但是无法访问
原因：
docker里面的host不能配置127.0.0.1 或者192.168.0.1 或则宿主机器将无法访问端口
解决方案
修改 /usr/local/elasticsearch-2.4.1/config 参数
# network.host: 192.168.0.1
network.host: 0.0.0.0将其改成0.0.0.0
启动后的效果如下

同理，我在docker里面配置了redis ，里面默认也是127.0.0.1 ，结果宿主机器无法访问docker端口
。这里根据上面的情况也将redis 配置成0.0.0.0
## Examples:## bind 192.168.1.100 10.0.0.1#bind 127.0.0.1bind 0.0.0.0# Specify the path for the Unix socket that will be used to listen for# incoming connections. There is no default, so Redis will not listen# on a unix socket when not specified.#
后来重启redis ，宿主机器也可以访问了
