Memsqlctl cannot find lock file /var/lib/memsql/nodes.hcl.lock

I’m trying to install a new MemSQL dockerized version with the following command:
docker run -i --init --name memsql
-p 3308:3306
-p 8080:8080
-v /app/database/memsql:/var/lib/memsql

The /app/database/memsql is totally empty before run.

I got the following error message:
memsqlctl cannot find lock file /var/lib/memsql/nodes.hcl.lock. To fix this, please run
· touch /var/lib/memsql/nodes.hcl.lock
· chmod 640 /var/lib/memsql/nodes.hcl.lock
· chown memsql:memsql /var/lib/memsql/nodes.hcl.lock (memsql:memsql are the owner and group of the node metadata file at /var/lib/memsql/nodes.hcl)
Traceback (most recent call last):

raise CalledProcessError(retcode, cmd, output=output)
subprocess.CalledProcessError: Command ‘[‘memsqlctl’, ‘-yj’, ‘list-nodes’]’ returned non-zero exit status 1

I’ve not idea what’s wrong…Could anybody help?
