Thanks to everyone who has contributed to this solution, and especially to @HuSoS for all of the detail. I used the info in your post but took a different route, since my dockers all have unique IP addresses on a custom network and I wanted to use Unraid's GUI rather than the compose plugin. Here's the write-up: Follow these steps from HuSoS's post above, replacing the internal IP address for signature_server in Step 6 with the custom address I would be assigning to the helper: Create a new container for the helper via the GUI: Docker > Add Container Switch to Advanced View Populate the following field values (icon is borrowed from Invidious docker, and optional): Name: inv-sig-helper Repository: quay.io/invidious/inv-sig-helper Icon URL: https://raw.githubusercontent.com/Joshndroid/joshndroid-unraid-docker-templates/main/icons/invidious.png Post Arguments: --tcp 0.0.0.0:12999 Network Type: [YOUR CHOSEN NETWORK | e.g.- Custom : br0] Fixed IP address (optional): [STATIC IP ADDRESS | e.g. - 10.0.1.111] Add another Path, Port, Variable, Label or Device Config Type: Variable Name: RUST_LOG Key: RUST_LOG Value: info Done Verify that the inv-sig-helper docker has successfully started (last line in the log should end with "Successfully fetched player") Start the invidious container, verify that the logs show no errors, and enjoy!

You're seeing this because you don't have any formatted partitions to install to (the folder you see is the install media, not a target disk). Reboot the VM and select "Disk Utility" from the recovery screen. There you will see multiple disks, including the one you allocated in the Macinabox parameters. Select that disk, the click the "Erase" button to format it. Once complete, you can return to the recovery screen and proceed with the install.
