 A short hint: Docker rootless uses Sub(g)uids, which is a feature of Linux. That means each user has a range of userids (quite a huge range) and groupid which the user may use. Those will be exclusive reserved for that user. But it does not mean, that the User can acces the Files created by those Subuids! Also the UIDs are onyl a number - not a real user in Linux having a username- They cannot be used to logon or to work with. Docker manages internally which Host-Subuserid is assigned to which caontainer and to which userid inside the running container/service. Inside the Container, you may become that user having a real username and a (different) uid.
+===== Which Devices / Raid- Level =====
+I strongly do not advise to use Raid5 with classical harddrives to run docker on it. If you plan to have large Data in /home/docker and you want to use xfs + Raid5 to better use your drive- space, than you should use another disc for the overlays of docker.
+For me, i switched to RAID1 on SSD an mounted that to /home/docker/.local - where all Docker files will be stored. Large Data is than stored somewhere else if needed.

+===== Find the latest Commit in git =====
+Sometimes the Repository does not offer a latest Tatg, so its hard to find the right Tag to use. Maybe this coding helps (not testet wheter to get the right commitid for the Image):
