I'm trying to run docker image on MacOS with VPN turned on (TUN device). Docker container can access internet, but is not able to access resources behind vpn. What is the right way to make Docker go to VPN network?
I've tried
docker run --net host to make docker share host network, it didn't help.
Host can access VPN resources, docker container can't resolve their names..
Not sure if it's best solution.
I took DNS that appears on my host after connecting to VPN
scutil --dns | grep 'nameserver\[[0-9]*\]'
nameserver[0] : xxx.xxx.xxx.xxx
Modified docker run command:
docker run --cidfile="docker.pid" --dns=xxx.xxx.xxx.xxx --publish-all
Now docker container can access resources behind VPN... It works, but I have no idea if it's good or bad...
Had a similar problem. OP's solution worked, but so did simply restarting my docker vm:
docker-machine restart $host
