  • When using the AWS EFS CSI Driver Operator, files on EFS are created using an unexpected User (UID) and group (GID), in the following example 50002 instead of 1002180000:

    $ id
uid=1002180000(1002180000) gid=0(root) groups=0(root),1002180000

$ ls /mount -al
total 8
drwx------.  3 50002 50002 6144 May  3 13:38 .
drwxr-xr-x.  3 root  root    18 May  4 10:06 ..
drwx------. 19 50002 50002 6144 May  3 13:39 example
