Running an Origin Trail node with docker

Hallo. I have this error and when i point on the decker logo it says, docker is running.
but it gives me this error.

error during connect: Get http://%2F%2F.%2Fpipe%2Fdocker_engine/v1.37/version: open //./pipe/docker_engine: The system cannot find the file specified. In the default daemon configuration on Windows, the docker client must be run elevated to connect. This error may also indicate that the docker daemon is not running.

I am trying to run the node on the testnet for origin trail.

docker run -it --name=otnode -p 8900:8900 -p 5278:5278 -p 5279:5279 -p 4043:4043 -p 8529:8529 -p 3000:3000 -p 3010:3010 --mount source=otnode-vol,destination=/ot-node --mount source=arango-vol,destination=/var/lib/arangodb -e INSTALLATION=local origintrail/ot-node

But it keeps giving me this error

docker: error during connect: Post http://%2F%2F.%2Fpipe%2Fdocker_engine/v1.37/containers/create?name=otnode: open //./pipe/docker_engine: The system cannot find the file specified. In the default daemon configuration on Windows, the docker client must be run elevated to connect. This error may also indicate that the docker daemon is not running.
See ‘docker run --help’.

What do I need to do to run the node?
