What it means

--user takes USER or USER:GROUP, each a name or a number, and replaces the user the image says it runs as. Names are looked up in the image's own /etc/passwd and /etc/group, so --user needs an image (a name that zbx pull made); a --rootfs directory or a bare tree has no image configuration to replace. The value is at most 256 bytes, with no space or control character and no empty part.
