Create APFS RAM disk on macOS High Sierra

Question

usually creating RAM disks works with the following commands

hdid -nomount ram://

Returns e.g. /dev/disk2 Then I would format

Answer 1

Also, info to delete/destroy the RAM disk needs to be corrected. ramdisk will be created at path /Volumes/'ramdisk', so the command is:

diskutil eject /Volumes/'ramdisk'
