dial tcp: lookup xxx.xxx.xxx.xxx: no such host

Editing the DNS nameserver in /etc/resolv.conf file helped me.

Change your existing nameserver to google nameserver i.e., x.x.x.x to 8.8.8.8

Comment your nameserver IP and add something like this :

#nameserver x.x.x.x
nameserver 8.8.8.8  

should work.

If you are behind a proxy, this could be your issue. In this case, you need to configure the Docker daemon (not the client) proxy settings. You can do that by:

1. Create a systemd drop-in directory for the docker service:
   • sudo mkdir -p /etc/systemd/system/docker.service.d
2. Create a file called /etc/systemd/system/docker.service.d/http-proxy.conf that adds the HTTP_PROXY environment variable:
   • [Service] Environment="HTTP_PROXY=http://proxy.example.com:80/"
3. Flush changes
   • sudo systemctl daemon-reload
4. Restart docker daemon
   • sudo systemctl restart docker
