Custom App help please? MAKEMKV

[akaVintz]

Hi All,
I am trying to deploy a custom app to my Truenas Scale device.
The url for the app is https://github.com/jlesage/docker-makemkv
If you look at the discussion page you will see me reaching out for help there.
Ive managed to get the app to a "Running" state but I have not added and "CMD" or "Arguments" and when I do it breaks.
The developer has provided this

Launch the MakeMKV docker container with the following command:

docker run -d \
--name=makemkv \
-p 5800:5800 \
-v /docker/appdata/makemkv:/config:rw \
-v /home/user:/storage:ro \
-v /home/user/MakeMKV/output:/output:rw \
--device /dev/sr0 \
--device /dev/sg2 \
jlesage/makemkv

Where:

• /docker/appdata/makemkv: This is where the application stores its configuration, states, log and any files needing persistency.
• /home/user: This location contains files from your host that need to be accessible to the application.
• /home/user/MakeMKV/output: This is where extracted videos are written.
• /dev/sr0: This is the first Linux device file representing the optical drive.
• /dev/sg2: This is the second Linux device file representing the optical drive.

Browse to http://your-host-ip:5800 to access the MakeMKV GUI. Files from the host appear under the /storage folder in the container.

My question is how do I input this into the custom app?
Docker is not a command on truenas so I imagine "docker run -d" will never work!
Do the back slashes just denote the end of the line and can they be deleted?
Would i put "-p 5800:5800" in an argument?

Sorry I am a newby with this stuff, I really like makemkv and when I saw this individual had created a docker image I couldnt ignore it but if it will newer work I will move over to the handbrake app published in the catalog.

Thanks for reading all of my ramblings
