From 3018043fc2b405e42070b49e965bc7a0a38ecf2a Mon Sep 17 00:00:00 2001 From: Patrick Figel Date: Mon, 11 Sep 2017 15:11:13 +0200 Subject: [PATCH] Add OpenStack Keystone V3 support (#4889) Keystone V2 is deprecated in favour of V3. This adds the necessary connection parameters for establishing a V3 connection. Connections to V2 endpoints are still possible and the configuration should remain compatible. This also introduces a SWIFT_REGION variable for multi-region OpenStack environments and a SWIFT_CACHE_TTL that controls how long tokens and other meta-data is cached for. Caching tokens avoids rate-limiting errors that would result in media uploads becoming unavailable during high load or when using tasks like media:remove_remote. fog-openstack only supports token caching for V3 endpoints, so a recommendation for using V3 was added. --- .env.production.sample | 8 ++++++++ config/initializers/paperclip.rb | 5 ++++- 2 files changed, 12 insertions(+), 1 deletion(-) diff --git a/.env.production.sample b/.env.production.sample index 3e054db84..e022a8405 100644 --- a/.env.production.sample +++ b/.env.production.sample @@ -101,11 +101,19 @@ SMTP_FROM_ADDRESS=notifications@example.com # Swift (optional) # SWIFT_ENABLED=true # SWIFT_USERNAME= +# For Keystone V3, the value for SWIFT_TENANT should be the project name # SWIFT_TENANT= # SWIFT_PASSWORD= +# Keystone V2 and V3 URLs are supported.
