允许docker容器访问Internet

Question

I would like my app inside docker to have access to the whole internet via host-machine.

I know that I can add particular ip --add-host=docker:10.6.210.32 But how can I add everything?

Answer 1

You can use --net=host in docker run command

docker run --net=host -it ubuntu

Else add dns in config file in /etc/default/docker

DOCKER_OPTS="--dns 208.67.222.222 --dns 208.67.220.220"
