Allan Hirt looks at contained SQL Server Agent Jobs:
I previously wrote about Contained AGs in SQL Server 2022 and demonstrated how to create a contained login. In this blog post, I’m going to talk about contained SQL Server Agent jobs because just like logins, they are a bit confusing from an administative standpoint in their current pre-release implementation (this blog post was written using SQL Server 2022 RC0 using SSMS 19 Preview 3).
It sounds like there’s still a ways to go on the tooling side of things.
