Create dedicated datasets

Login to your Truenas server via SSH. Run the following command ls /mnt share the results.
Startup the Truenas CLI by running cli
Copy and paste the following commands into the TrueNAS CLI: # Replace 'tank' with your Apps' pool name
Create docker dataset storage dataset create name=tank/docker share_type=APPS
Create dockge dataset storage dataset create name=tank/docker/dockge share_type=APPS
Create dockge/stacks dataset storage dataset create name=tank/docker/dockge/stacks share_type=APPS
Create dockge/data dataset storage dataset create name=tank/docker/dockge/data share_type=APPS

Create crafty datasets:

storage dataset create name=tank/docker/crafty/backups share_type=APPS
storage dataset create name=tank/docker/crafty/logs share_type=APPS
storage dataset create name=tank/docker/crafty/config share_type=APPS
storage dataset create name=tank/docker/crafty/import share_type=APPS
storage dataset create name=tank/docker/crafty/servers share_type=APPS

Exit CLI exit

Configure ZFS Record Sizes

Ensure that the record sizes are optimized for each dataset based on its specific workload: # Adjusting the 'recordsize' helps improve performance

Navigate to "System > Shell" in the TrueNAS interface.
Copy and paste the following commands into the TrueNAS shell: # Replace 'tank' with your Apps' pool name

sudo zfs set recordsize=16K tank/docker

sudo zfs set recordsize=16K tank/incus

Deploy and configure Dockge as a Truenas application

Use Dockge to manage all your Docker stacks. To install it:

Navigate to "Apps > Discover Apps" in the TrueNAS interface.
Search for "dockge" and click to install.
Navigate to "Network Configuration" in the installation interface.
Keep the default "WebUI Port": 31014
Navigate to "Storage Configuration" in the installation interface.
Choose the following type in "Dockge Stacks Storage":

Host Path (Path that already exists on the system)
Insert the following path in "Host Path": # Replace 'tank' with your Apps' pool name

/mnt/tank/docker/dockge/stacks
Choose the following type in "Dockge Data Storage":

Host Path (Path that already exists on the system)
Insert the following path in "Host Path": # Replace 'tank' with your Apps' pool name

/mnt/tank/docker/dockge/data
Click "Install" and wait for the green "Running" status indicator.
Click on the "Web UI" button in the "Application Info" section to open Dockge.
Change the URL to "https://" and press Enter. # Add this page to your browser's bookmark bar
Set your "Username" and "Password". # Confirm password
Click "Create".
