docker plugin set seaweedfs-csi:swarm FILER=<IP>:8888,<IP>:8888
docker plugin set seaweedfs-csi:swarm CACHE_SIZE=512
docker plugin enable seaweedfs-csi:swarm
docker volume create --driver seaweedfs-csi:swarm --availability active --scope single --sharing none  --type mount --opt path="/docker/volumes/teste1" test-volume

docker volume create \
  --driver seaweedfs-csi:swarm \
  --availability active \
  --scope multi \
  --sharing all \
  --type mount \
  testVolume

  docker service create   --name testService   --mount type=cluster,src=testVolume,dst=/usr/share/nginx/html   --publish 2080:80   nginx
```

Volumes are store in the "/buckets" folder on the Seaweed server.
