问题 I cannot reach external network from docker-compose containers. Consider the following docker-compose file: version: '2' services: nginx: image: nginx Using the simple docker run -it nginx bash I manage to reach external IPs or Internet IPs ( ping www.google.com ). On the other hand if I use docker-compose and attach to the container, I cannot reach external IP addresses / DNS. docker info: Containers: 0 Running: 0 Paused: 0 Stopped: 0 Images: 1 Server Version: 1.12.1 Storage Driver: aufs
