Docker Unknown flag --mount

问题

I want to mount a directory from the host to a container using the mount flag over volume but I am getting ` This is only experienced when using mount flag and not with volume

*Command:*
    docker run -d  -it  --name devtest --mount type=bind,source="$(pwd)",target=/home/  httpd

Error unknown flag: --mount

docker run support for the --mount option was only introduced in Docker 17.06. You are using Docker 1.13.1. You have two choices:

1. Update to Docker 17.06 or later if you can;
2. Use the -v approach to bind mount the volume you require e.g. docker run -v $(pwd):/home
