Hello, I have a problem with Ghost posts, every time I upload a post, it disappears after a while and only the first post I wrote remains. Ghost works on a friend’s web hosting and I did it via a Docker image. Is there a bug in the Docker image or in the hosting itself? Thanks for the answer.

As an alternative, you can also use bind mounts:
