DI 1: Standard Tag Format

Current status within Docker

ONAP Nexus 3 which contains ONAP Docker images is structured as below:

• Docker Release: ONAP released Images
• Docker Staging: currently empty
• Docker Snapshot: the big pile

What do we Need stanardardized Docker format

As Docker Snapshot is a cumulative repository, given a version, a keyword and the name of an image, the need is a systematic method to sort chronologically images based on Nexus version field.

This will help to community in providing an automated deployment using tag sets on a standard format.

Proposal

The proposed docker tag format to align across all the teams is the following:

X.Y.Z follows the Semantic Versionning

Example

See similar examples of the current tag structure by browsing the links below. Unfortunaltly there is no consistency among projects. Note these examples have additional keyword (such as SNAPSHOT) that are currently not deemed necessary.
