What is Glance? Glance is the OpenStack Image Service. Glance provides services and associated libraries to store , browse , share , distribute and manage bootable disk images, other data closely associated with initializing compute resources … and metadata definitions.

What is Glance? Glance has been around since the Bexar release of OpenStack. Latest survey results indicate that Glance is deployed in 95% of clouds in production or test phases.

What is Glance? Glance is … ● A project (i.e., a community of contributors) ● A service (provides an implementation of the Image Service and associated software) ● An API (defines a means of interacting with the service)

Wait … An API? Yes, singular. In Queens, the v2 API will be the only one. ● User survey: 37 responses ○ already migrated: 19 ○ planning: 5 ○ inertia: 3 ○ ambiguous: 8 ○ problems: 2

The Glance Project Pike Reviews ● ○ 104 contributors from 36 companies Commits ● ○ 79 contributors from 31 companies Queens Reviews ● ○ 41 contributors from 19 companies Commits ● ○ 24 contributors from 16 companies

The Glance Service The Glance project is responsible for the following code repositories: openstack/glance ● ○ The glance server ○ The glance registry (deprecated!) ○ Most of the Glance documentation openstack/glance_store ● ○ A library that facilitates access to the supported storage backends openstack/python-glanceclient ● ○ A python client library and CLI openstack/glance-specs ● ○ Design documents for Glance

OpenStack Pike Features The Pike release is Glance 15.0.0 Primary feature is the MVP of interoperable image import (not enabled by default) ➡ There’s a full session on image import later today (4:30-5:10 pm, Level 3, Cockle Bay Room 2)

OpenStack Pike Features Interoperable Image Import ➡ EXPERIMENTAL API v. 2.6 ➡ Configuration information is available in the Glance documentation docs.openstack.org/glance/latest/admin/ (Look for “interoperable image import”)

OpenStack Pike Features See the release notes for some other features docs.openstack.org/releasenotes/glance/ (Pick the Pike Series Release Notes)

OpenStack Queens ➡ Complete Interoperable Image Import ➡ Automatic Metadata Injection ➡ Secure Hash Algorithm Support (“multihash”) ➡ Fix OSSN-0075 … and more (though not much more) Priorities list: specs.openstack.org/openstack/glance-specs/ (Look for Queens Priorities)

Beyond Queens We held a “strategic planning session” at the Denver PTG for releases Q through U etherpad.openstack.org/p/glance-queens-ptg-strategic-plan (Of course, it’s very speculative, but here are some highlights)

Beyond Queens R (Spring 2018) ➡ image lifecycle management part 1 • “Hidden images”, please provide feedback: • https://review.openstack.org/#/c/508133/ ➡ quotas -- at least figure out what we're going to do and what the scope is • Need a driver for this ➡ swift store feature complete ➡ multiple store support complete ➡ Interoperable image import testing fully covered

Beyond Queens S (Fall 2018) ➡ image lifecycle management part 2 ➡ better metadefs integration (value enforcement) ➡ image export ➡ ceph store enhancements ➡ glance registry removal ➡ multi-region support part 1

Beyond Queens T (Spring 2019) ➡ Task worker separation from glance-api U (Fall 2019) ➡ multi-region support complete

Contributors Needed Glance is currently on the OpenStack “Top 5” list ➡ We need more contributors, particularly if the features people want are going to be implemented

How to contribute There are lots of opportunities depending on your interests. ➡ Coding, fixing bugs ➡ Reviewing code ➡ Documentation and docs publishing ➡ Topic driver ➡ Reviewing specs, developing specs More info: etherpad.openstack.org/p/SYD-forum-glance-onboarding

How to give feedback Well, you could have attended yesterday’s Forum session :) You can still leave feedback on the etherpad: https://etherpad.openstack.org/p/SYD-forum-glance-feedback

How to give feedback More ways to give feedback: ➡ Open discussion at the weekly Glance meeting (Thursdays at 14:00 UTC in #openstack-meeting-4) ➡ Discussion in the #openstack-glance channel (I’m usually in there weekdays; I’m in the New York time zone) ➡ Glance operator surveys (announced on the operators’ list with [glance-survey] in the subject line) ➡ Openstack-dev mailing list, with [glance] in the subject
