I - Newbie to all this Unraid Stuff - had the same problems, and thanks to this simple but awesome guide on YouTube (https://www.youtube.com/watch?v=NxgMjv2IgIU - Protect Your Unraid Setup from Disaster 🔥 | Docker Auto-Backup with Config Guardian by AlienTech42), I realized that I hadn't created a custom network for DockerSocket and UnraidGuardian to communicate with each other. I had managed to connect UnraidGuardian to DockerSocket without creating a custom network, but the container list only showed templates instead of my Docker containers. I also had to change the setting from tcp://dockersocket-ip:2375 to tcp://dockersocket:2375. It would be good if this information were included alongside the information that you have to create the IMAGE variable.
