docker啓動容器發現端口是tcp6，致使沒法訪問

1. 問題背景

[root@dc02 ~]# sudo docker run -p 5601:5601 -p 9200:9200 -p 5044:5044 -it --name elk elk:v2 WARNING: IPv4 forwarding is disabled. Networking will not work.  * Starting periodic command scheduler cron [ OK ] * Starting Elasticsearch Server                                                                                  [ OK ]

在瀏覽器中沒法訪問

2. 解決辦法

[root@dc02 log]# vim  /usr/lib/sysctl.d/00-system.conf 加入一行 net.ipv4.ip_forward=1 重啓網絡 [root@dc02 log]# systemctl restart network 測試網絡連通性 [root@dc02 log]# ping baidu.com PING baidu.com (123.125.115.110) 56(84) bytes of data. 64 bytes from 123.125.115.110: icmp_seq=1 ttl=128 time=3.61 ms 64 bytes from 123.125.115.110: icmp_seq=2 ttl=128 time=2.73 ms 重啓docker [root@dc02 log]# systemctl restart docker.service
