When I run my build command, I will always get an error... (28, 'Resolving timed out after 5000 milliseconds' )   ... due to the lack of network access. I have compared my host and container /etc/resolv.conf , and noticed they were different. Example (Host) # Generated by expressvpn
search expressvpn
nameserver 10.53.0.1   Example (Container) search expressvpn
nameserver 10.1.2.3
nameserver 8.8.8.8   I attempted copying the host /etc/resolv.conf and overwriting the container /etc/resolv.conf as follows $ echo "# Generated by expressvpn
> search expressvpn
> nameserver 10.53.0.1" > "/etc/resolv.conf"   Then immediately gained network access again and was able to use yum . However, if I try reading the Dockerfile with a build command, it does not seem to work anymore. How do I make docker use the host resolv.conf on build or resolve this issue correctly? It seemed to not have an issue with my VPN before. Is that the issue now?

I was able to at least get my docker to build the containers by taking the same naming conventions used in the (https://docs.docker.com/engine/reference/commandline/dockerd/) Docker Daemon CLI options and applying them to a /etc/docker/daemon.json manually, then restarting the Docker Daemon. Read the host /etc/resolv.config (Yours will likely be different)  $ cat /etc/resolv.config # Generated by expressvpn search expressvpn
nameserver 10.53.0.1   Make a new, or use the /etc/docker/daemon.json (I had to use Super User to write the file)  $ sudo touch /etc/docker/daemon.json   Use the Daemon file to manually set the Virtual Network to the host /etc/resolv.conf output as described in #1 (Again yours is likely to be different). You can find the different options (https://docs.docker.com/engine/reference/commandline/dockerd/) here just use the CLI options as keys and arrays with strings as values.  { "dns" : [ "10.53.0.1" ] , "dns-search" : [ "expressvpn" ] }   Hard stop all docker processing  $ sudo ps axf | grep docker | grep -v grep | awk '{print "kill -9 " $1}' | sudo sh   Restart Docker Daemon  $ sudo dockerd   This is not the most elegant solution, but I was able to at least get my Docker to build the Container and continue on with my work.

Docker overrides the resolve.conf file so it matches the virtual network it is setting up. You may have an atypical network setup for your container that is screwing up Docker. There are two ways to automate the fix you came up with above: The --dns (https://docs.docker.com/config/containers/container-networking/) option in the command line should tell Docker how to properly create the resolve file how you want it. (https://unix.stackexchange.com/a/348406/234861) You can overwrite the resolve file at start.   You can also try to figure out why Docker is getting screwed up, but that is a potentially much more complicated problem.
