@heitor me and @jamesbeedy has been requesting that we develop a visualization that accurately reflect the exakt state machine and its transitions which also contains information about what data is available to the units and relations in various states.
The image above I fear is not 100%, but rather something I’ve recreated with help från @Dmitrii and some own discoveries.
This a really fundamental flaw in the general teaching/learning material which I would love to get an accurate version of in the official docs.
This visualization helped me (and still does) alot when I was trying to learn, not only, relations with Juju.
This has also been discussed in other threads: Ubuntu OnAir - Community Office Hours - 1st July 2021
