Unable to access the Internet via HTTP container within Docker

phenomenon

• Internal / external IP network domain and can ping
• Unable to access the container within the host where the network and external network of Web services (404)
• View header information returned by curl feeling is that all Web requests are relayed to a fixed server Nginx
• All containers (including newly created) all the above problems

analysis

• By  docker run --net host the above-mentioned problem does not exist to create container
• docker run Default  bridge bridged networking, the initial judgment was  bridge set problem
• By  custom bridge  also not solve the problem
• The final suspect is bridging the network card on the host  docker0 issues

solve

By rebuilding  docker0 solve network problems

$ sudo service docker stop
$ sudo pkill docker
$ sudo iptables -t nat -F
$ sudo ifconfig docker0 down
$ sudo brctl delbr docker0
$ sudo service docker start

Temporarily solved the problem.
