EKS D Release process detailed activity diagram

[danbudris]

The EKS Distro release process is a fairly involved sequence of events spanning multiple systems. By documenting the flow of events across systems in a visual manner we can better understand the system as a team, have better common language about the system, and more effectively plan our improvmeents to the system.

The outcome of this ticket is an activity diagram or flow chart which displays the EKS D release process, ideally as code (e.g. UML), which can be updated as the process evolves.
