I would like to migrate the docker to the truenas. But I would like to run the docker which pull from docker hub and using the cli on previous system but found that not working in the truenas.

docker pull fizzymatt/nessus-7-ubuntu

docker run -d --name nessus-7-ubuntu 8834:8834 fizzymatt/nessus-7-ubuntu
