Users and Directories
By default this image runs as a non-root user named etcd with a uid of 65532.
The default data directory for this image is /var/lib/etcd, and that directory is write-able by the etcd user.
If you change the user, UID, or data directory, you'll need to ensure the user running the etcd process has permissions to that
directory.
