docker容器中不能上网的一种解决方法

After A LOT of time trying to solve this issue I think I finally found a solution in an ebook I found on the internet. Here's the steps I took to solve the issue: $ sudo service docker stop $ sudo nano /etc/default/docker Edit the file and uncomment the DOCKER_OPTS option modifying it to somthing like this: DOCKER_OPTS="--dns 8.8.8.8 --dns 8.8.4.4 --iptables=false --ip-forward=false" $ sudo su $ echo 1 > /proc/sys/net/ipv4/ip_forward // Add the IP range you want to have access to the internet $ iptables -t nat -A POSTROUTING -s 172.17.0.0/16 -j MASQUERADE $ service docker restart $ exit Now hopefully your containers have access to the internet again. I hope to help someone :) 转载自github: https://github.com/moby/moby/issues/36151#issuecomment-630548256
