Possibly a noob question here but… When I create a volume it includes a “_data” folder, which is where data goes if I pass the volume directly into a container. If I create a folder inside the volume and pass that folder into the container, then the data lives there, outside the _data folder. What is the intended purpose of the _data folder in the volume if it’s just an extra storage layer for 100% of the volume contents to go in?
More importantly, if I want to create subfolders in the volume (and pass those individually to the container) it appears to work the same if I place them into the _data folder versus in the root of the volume, so is there some reason it’s better to stay in the _data folder versus a minimal bit of decluttering my Docker run command?
Edit: Just in case this doesn’t apply to all versions of Docker… I am working in Docker in the Photon OS 3.0 VM by VMWare.
