What is this running container on my storagenode?

Loooking my running container I have the last container in the pic named TKzxfZNCfUgpcHfiOuVtAFylXiDREppJ running, anyone can tell me what is this one ?

This is duplicated watchtower, You can tell by command. You can easily do:
docker stop 897a8dc...
docker rm 897a8dc...

To be sure that container of ID watchtower isn’t older than the duplicate, you can stop, remove watchtower container and start fresh, up to date watchtower by running

docker pull storjlabs/watchtower
docker run -d --restart=always --name watchtower -v /var/run/docker.sock:/var/run/docker.sock storjlabs/watchtower storagenode watchtower --stop-timeout 300s --interval 21600

I also got duplicated watchtower previously that is why I end up using bash script which keeps node in order.
