Docker container issues

If you run varys-cli inside a docker container and you get the following error:

...
Driver:warn Timed out waiting for page load. Checking if page is hung...
Driver:warn Page appears to be hung, killing JavaScript...
status Disconnecting from browser...
ChromeLauncher Killing Chrome instance 58
Runtime error encountered: Waiting for DevTools protocol response has exceeded the allotted time. (Method: Emulation.setScriptExecutionDisabled)

LHError: PROTOCOL_TIMEOUT

you may need to increase shm when running the container by adding --shm-size=256m

docker run <build id/build tag> --shm-size=256m
