ava tests run ok on windows & linux, but not ok inside docker.

according to elgalu/docker-selenium#20 (comment) , this is due to /dev/shm memory size too small.

$ df -h
shm              64M  3.2M   61M   5% /dev/shm

it's only 64M

Solution

1. increase shm size with --shm-size param with build & run Addition of "--shm-size" to which size of /dev/shm is changed moby/moby#16168 (comment)
2. use --privileged when run docker, then mount /dev/shm -o remount,size=1g bigger /dev/shm moby/moby#2606 (comment)
3. use -v /dev/shm:/dev/shm when run docker. node-chome tab crash in docker only SeleniumHQ/docker-selenium#79 (comment)
