2. This project will deliver re-usable artifacts & tooling to help ONAP projects simplify the development of vendor-agnostic container images using build templates that implement industry best practices.

3. CONTAINER IMAGE
A vehicle to pack, ship, store, and deliver applications. Immutable, self-contained piece of software. Can be built by commands contained in a file.

4. 149
Dockerfiles

5. Opportunities to simplify image builds and save time.
Variability.
Low re-usability.

10. LARGE IMAGES WASTE TIME AND RESOURCES
Take longer to build and debug.
Take longer to pull.
Consume more disk space bandwidth and memory.

11. BASE IMAGES IMPACT DEPLOYABILITY*
Operators should choose their infrastructure/cloud provider.
Container image specification supports multi-cpu architecture layers.
ONAP images do not support multi-cpu architecture (yet).

12. Architecture Principles
ONAP IS VENDOR-AGNOSTIC
Charter
1.b. ONAP will include product / service / resource agnostic platform modules for lifecycle management
Architecture Principles
All components should be software-based with no dependency on hardware platform.
..the cloud platform implementation should be pluggable and transparent to the ONAP components.
The ability for ONAP to be used by various users worldwide dictates the need to avoid dependency on any single supplier(s).
