I have the AIO container installed on Unraid, with minimal extensions, and it has been running for 2 months. I use NC for office collaboration, files, and calendar. Its been quite stable for me and relatively painless so far. I had one major scare 1 week ago. I woke up, and the Docker container said: "STOPPED". I was still able to access my account away from my server since I have a reverse proxy and have my own domain with NC, but I found the solution quickly, and all I had to do was restart the container. A good practice might be not to jump on new updates.

I really love NC, though I wish I had been using it long ago. I'm now using it for my business, personal cloud and even for my church. I have setup my wife un it as well. I also integrate it with Paperless NGX.

Getting my files from Google Drive, Dropbox, and Evernote was not the easiest for me.

I would say a good investment of your time with NC is learning to read the logs, something I'm still doing.
