Docker Standard Tag Format

Description

As a community we need a consistent way to tag the Docker images so that we can sort them chronologically.

 

The need is also documented in the wiki.

Current status within Docker

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

What do we Need standardized 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-KEYWORD-yyyymmddThhmmssZ

X.Y.Z follows the Semantic Versionning

KEYWORD: SNAPSHOT or STAGING

Example

1.1.2-SNAPSHOT-20181231T234559Z

Sorry I meant  x.y.z-STAGING-yyyymmddThhmmssZ . The releases need to come from a  x.y.z-STAGING-yyyymmddThhmmssZ tag

Former user April 4, 2018 at 8:51 PM

Releases will be done with x.y.z-STAGING images right? Since the jobs that create the staging images should be using already released/signed java artifacts, while the snapshot docker images will probably contain unreleased snapshot java code.

Done
