docker how to connect to external DNS
I have docker container (lets say A) running on a host (lets say X). I would like the container to be able to have outbound connectivity to a DNS (ie ELB) that host X already has access to.
ie
container A ---> want to be able to curl an external ELB DNS endpoint...problem is container unable to resolve it!
host X ---> is able to curl the external ELB DNS endpoint already

Do either of these work for you?
$ docker run --dns 10.0.0.2 busybox nslookup google.com
Or edit your /etc/docker/daemon.json similar to:
{
"dns": ["10.0.0.2", "8.8.8.8"]
}
and restart the docker service
$ sudo systemctl docker restart
For more information, please see Fix Docker's networking DNS config and Container networking.
