Docker容器上无互联网访问

Question

I've just installed docker on a virtual machine and created a ubuntu container. When I run "apt update" I get the following errors.

Err:1 http://archive.ubuntu.com/ubuntu xenial InRelease
Temporary failure resolving 'archive.ubuntu.com'
Err:2 http://archive.ubuntu.com/ubuntu xenial-updates InRelease
Temporary failure resolving 'archive.ubuntu.com'
Err:3 http://archive.ubuntu.com/ubuntu xenial-security InRelease
Temporary failure resolving 'archive.ubuntu.com'

All packages are up to date.

W: Some index files failed to download. They have been ignored, or old ones used instead.

I already tried to enable the DOCKER_OPTS in /etc/default/docker to use Google's DNS and restarted docker, but it didn't work.

I also tried this:

pkill docker
iptables -t nat -F
ifconfig docker0 down
brctl delbr docker0
docker -d

How can I solve this problem?

Answer 1

Already solved it. What I had to do was comment out the

dns=dnsmasq

entry located in /etc/NetworkManager/NetworkManager.conf .
