If everything you’re running is in a Docker container, you can see if the underlying NAS OS has or can support Docker. If so, you could consider migrating some apps since that kind of migration should be pretty straightforward depending on how you setup your containers.

I have a Synology NAS and I went from managing my containers through Synology apps to just running everything through the command line directly.

More recently I stumbled onto Homepage (https://gethomepage.dev/) to keep an eye on my apps, and I started using the free edition of Portainer (CE, https://github.com/portainer/portainer) to manage my containers. I even have two Portainer containers running on different servers and I can manage them directly from one Portainer instance.

Individually Homepage and Portainer were game changers for me since they solved specific gaps I had in my manual processes.

If you’re in the mood to rethink your entire setup, I would recommend looking into Homepage and / or Portainer.

I progressively migrated containers into Portainer stacks while also putting everything into Homepage, so I just moved along at my own pace.
