DNS issue with docker image
What worked for me was this guide.
from https://stackoverflow.com/a/40516974 (YOUR_DNS_IP_HERE is my addition)
Put this in /etc/docker/daemon.json:
{ "dns": ["YOUR_DNS_IP_HERE", "YOUR_DNS_IP_HERE"] }
Exit from root:
exit
Now restart docker:
sudo service docker restart
VERIFICATION:
Now check that adding the /etc/docker/daemon.json file allows you to resolve 'google.com' into an IP address:
docker run busybox nslookup google.com
