bash: VOLUME: command not found

hello, i'm getting this error while build ...

Rocket.Chat.Embedded.armhf/docker/rocketchat# docker build -t rc .

The command '/bin/sh -c groupadd -r rocketchat && useradd -r -g rocketchat rocketchat && mkdir -p /app/uploads && chown rocketchat.rocketchat /app/uploads VOLUME /app/uploads' returned a non-zero code: 139

so i tried manually typing one command at a time .. it works but this command hits error:
VOLUME /app/uploads
bash: VOLUME: command not found

it might be docker version compatibility problem. @jepunband did you ever get past it?
