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

Design documents for Glance

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 Pike Features

➡ 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)

OpenStack 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

Beyond Queens

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

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
