Bash on windows : ERRORS

I am actually trying to install docker in bash for windows but the docker daemon won’t start …

$ dockerd

Error starting daemon: Devices cgroup isn’t mounted

then

I TRIED SOMETHING LIKE THIS :

I added in /etc/fstab the line :
cgroup /sys/fs/cgroup cgroup defaults 0 0

then I tried : “$ mount /sys/fs/cgroup”

but … ==> error : unrecognised cgroup…

and finally :
$ sudo dockerd

same errors :

Error starting daemon: Devices cgroup isn’t mounted

can someone help please ?
