Docker容器访问本地DNS

Question

Due to company restrictions I'm having to run docker inside a VMware Workstation VM with Ubuntu installed from a Windows host.

From the Ubuntu terminal I'm able to ping by domain to both, Internet servers and servers from the local network. When I run a docker container I can't resolve any domain even though I can ping to both IPs.

docker run -t mycontainer

If I run the docker container setting the local DNS using the --dns LOCALDNS option, I'm only able to resolve domains servers on Internet but not from the local network. I'm now running the containers like this:

docker run --dns XX.XX.1.1 -t mycontainer

Is there a way to configure the docker network so that the containers can resolve local AND Internet servers?

Thank you

I just found out a solution to the problem. Additionally to the --dns option I had to add the --dns-search option with the domain name. The command I'm using is as follows:

docker run --dns XX.XX.1.1 --dns-search companydomain -t mycontainer
