TrueNAS-Compose | Your Docker Stacks for TrueNAS

WARNING: If you installed anything before May 1, 2025, you'll need to start over due to major changes in the dataset and network structure!

Setting Up TrueNAS Before Using Docker Stacks

Before you use this Docker stacks, make sure you have completed the following steps to properly configure TrueNAS:

[ Click to Expand ]

Step 1: Install TrueNAS Community Edition - Follow the official instructions from the TrueNAS website to install it on your hardware.

4. Click "Save".
Step 4: Configure Location - Ensure that your regional settings are properly configured:
1. Navigate to "System > General Settings > Location" in the TrueNAS interface.
2. Click "Settings".
3. Change the default settings to match your regional settings and formats.
4. Click "Save".
5. If needed, change the date/time settings in your TrueNAS system's BIOS to match your local date/time. # Correct date/time is crucial for logs and network services to work properly
Step 5: Configure Network - Ensure that your network settings are properly configured:
1. Navigate to "Network > Interfaces" in the TrueNAS interface.
2. Click on the "Edit" button of your network interface to access the interface settings.

Step 6: Create ZFS Pools - You'll need to create at least one ZFS pool to store your System/Apps data:
1. Navigate to "Storage" in the TrueNAS interface.
2. Click on the "Create Pool" button near the top right.
3. Type "tank" on the "Name" field. # This is the default name used in ZFS documentation and in this guide

12. Click "Save And Go To Review".
13. Click on the "Create Pool" button to create your System/Apps pool.
14. Confirm that "The contents of all added disks will be erased" and click "Continue".

7. Select your source location: # Replace 'tank' with your Apps' pool name
8. Select your target location: # Replace 'backups' with your Backups' pool name
9. Check "Recursive".
10. Type "tank_backup" in the "Task Name" field.
11. Click "Next".

16. Click "Save".
17. In the future, configure replication tasks on the datasets associated with your Docker volumes instead.

Step 13: Create ZFS Datasets - You'll need to create datasets within your ZFS pools to organize and manage your data:

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

5. Check "Apply permissions recursively" and confirm.
6. Check "Apply permissions to child datasets".
7. Click "Save Access Control List".
8. Repeat steps 1-7 for the "media" and "downloads" datasets (instead of the "docker" dataset), which are located at the root of your Media/Downloads' pool.
9. Repeat steps 1-7 for the "data" and "games" datasets (instead of the "docker" dataset), which are located at the root of your Data/Games' pool.
Step 16: Configure Users - You'll need to create a user account to access and manage your TrueNAS system:
1. Copy and paste the following command into your terminal (on your local computer): # Ed25519 is a public-key signature system, more secure than RSA
2. Press "Enter" to accept the default location:
3. Enter a passphrase for extra security. # This will secure your private key
