File 0001-SECRETS-daemon-allow-directory-creation-in-run-secre.patch of Package docker
From ec53ee338835c4c1dc583695ac166f36bf3bac5c Mon Sep 17 00:00:00 2001 From: Aleksa Sarai <asarai@suse.de> Date: Wed, 8 Mar 2017 12:41:54 +1100 Subject: [PATCH 1/7] SECRETS: daemon: allow directory creation in /run/secrets Since FileMode can have the directory bit set, allow a SecretStore implementation to return secrets that are actually directories. This is useful for creating directories and subdirectories of secrets.
