Any disadvantage running Ghost off of the official docker image?

Using Unraid with Cloudflare. Got the docker running, was able to make some change to the config, and it seems running smoothly, but haven’t done anything advanced yet.

Any disadvantage to using this method vs running a full blown VM on Ubuntu (which incidentally the official documentation is broken)?

I personally like to run ghost on docker. The thing I noticed is that the official docker image doesn’t get updated immediately after a new ghost release. But I am happy with that. It actually avoids the bugs on the latest release if any
