I am on nomad version 1.10.2

Volume definition

namespace = "default"
name      = "static"
type      = "host"

# mkdir is the default built-in plugin
plugin_id = "mkdir"


parameters = {
  mode = "0777"
  uid  = 1000
  gid  = 1000
}

Created folder

drwxr-xr-x  2 1000 1000 4096 Jul  3 08:35 a0d676eb-3912-9738-2023-4e952acdd781

The UID and GID is set allays correct.

But setting of mode ="777" is not applicated (some containers like postgres need 777 voume at start).
