README example not working, getting `Error: SessionNotCreated, Unable to create new service: ChromeDriverService` about thirtyfour

I was also unable to run the examples with the docker selenium startup in the README, but I did get it working with this version that isn't using the host network.
docker run --rm -d -p 4444:4444 --name selenium-server -v /dev/shm:/dev/shm selenium/standalone-chrome:3.141.59-zinc

FWIW, I was also able to reproduce the output from @d1618033 using a the firefox version of the container. I started the firefox container version like this:
docker run --rm -d -p 4444:4444 --name selenium-server -v /dev/shm:/dev/shm selenium/standalone-firefox:3.141.59-zinc

OS: MacOS 10.14
Docker: 19.03
Cargo: 1.40

I forgot that OSX does not work with host networking. I suspect that is the issue. I chose to use host networking for the example to avoid issues with DNS lookups in docker (which requires some config on OSX and possibly Ubuntu / other distros depending on how DNS is configured on the host).

This would probably work for you by using -p 4444:4444 instead of --network host. If it complains of not being able to reach wikipedia (or whatever url you put in), you may need to also specify --dns <your_dns_server_ip> so that the container can resolve external DNS lookups.

There is a way to make the DNS setting permanent in the docker config. If you're on OSX, Docker desktop has a GUI for editing the config. On Linux, it's at /etc/docker/daemon.json.

Thanks @tjtelan, I'll check it out

@d1618033 I've merged in changes from @tjtelan that should fix your issue.

Let me know if this works for you now.

Works great, thank you!
