How can you make the Docker container use the host machine's '/etc/hosts' file?

Question

I want to make it so that the Docker container I spin up use the same /etc/hosts settings as on the host machine I run from. Is there a way to do this?

Answer 1

Also you can install dnsmasq to the host machine, by the command:

sudo apt-get install dnsmasq

And then you need to add the file /etc/docker/daemon.json with content:

{
    "dns": ["host_ip_address", "8.8.8.8"],
}

After that, you need to restart the Docker service by command sudo service docker restart

This option forces to use the host DNS options for every Docker container. Or you can use it for a single container, and the command-line options are explained by this link. Also docker-compose options are supported (you can read about it by this link).
