  OP's version: > UIDs below 10,000 are a security risk on several systems, because if someone does manage to escalate privileges outside the Docker container their Docker container UID may overlap with a more privileged system user's UID granting them additional permissions. > [...] there may sometimes be reasons to not do what is described here, but if you don't know then this is probably what you should be doing. Your version: > Use what you like. > UID=1000

    I should probably also mention this example is for docker images that I use for local development with a shared file mount having the same UID/GID as your host, so you don't have to `chown` all the time while developing.

  > more like random practices somebody prefers Surely, if "X" has posed a security flaw in the past, and "Y" achieves the same as "X" without being vulnerable to the exploits (e.g. the UID advice), then "Y" is objectively better and not a matter of style, is it not?
