[openstack-dev] [Zun][Glare][Glance] Building Docker images

Hello to All.
I’d like to get initial feedback on the idea of building Docker images
through Zun involving Glare as artifactory for all static components
required for image.
So, the idea here is in being capable to build a Docker image through Zun
API with storing all static data required for docker image building in
Glare or Swift. In order to keep the same UX from using Docker it would be
better to use Dockerfile as description format for image building.
In image creation process Glare could take role of artifactory, where users
stores, let’s say source code of his applications that would run in
containers, static data, etc. And those artifacts will be pulled during
image creation and used to inject into image (similar process of context
creation during Docker image building using native CLI). Please note that
artifacts are completely optional for images, but would give a capability
to keep artifacts in dedicated storage instead of transferring all data
through Zun API (the opposite concept to Docker build context).
Once image is created, it can be stored in underlying Docker in Zun or can
be published into Glance or Swift for further consumption (if user will
need to save image, he’ll use Glance image download API). I’ve mentioned
Swift VS Glance because Swift has concept of temp URLs that can be accessed
without being authorized. Such feature allows to use Swift as storage from
where possible to export image to Docker using Import API .
Any feedback on the idea is appreciated.
