Rationale
The ONAP developer community and early adopters have expressed concern with the size of the images. A strong rationale is to optimize ONAP image sizes.
Images contained the in official repositories have clear documentation, promote best practices and support common use cases.
Using the base images provided here, users could still build a custom images with just the necessary pre-compiled libraries to save space.
Guidelines
- Use images from the Official Repository available here:
ONAP projects are encouraged to use the images listed below.
These images can be sourced from official, curated repositories, for example https://hub.docker.com/explore/?page=1
