alt Hacker NewsYeah, but it does not have to.
There are for example products like keycloak. OpenID/OAuth2/Token/Security IdP in a box.
Why there is not ticket system in a box? Yeah, we all know Jira and friends, but these are products not building blocks.
Another angle is: Why the hack does everyone rewrite their microservice foundation. Inbox/Outbox/Worker Queue/Throtteling/tracing/..... What happened to the application servers of the past?
I am a big supporter of that narrative. Why do I need to write more than my dedicated business logic and wire up some UI (and do not get me started on UI space).
IMHO, this can be a real differentiator for the language platforms. Ruby has parts of it, but is still far of.

There exist stable solutions for all of this, at least in the java world. Spring Boot and the exhaustive Spring Boot auto configurations are all about this…

It‘s no called kubernetes. With the caveat of it not having first class integration for any language, but second class integration for all languages.
One reason might be that microservice foundations tend to become frameworks rather than building blocks.
Auth is a building block you can slot into your system and the shape of the hole isn't all that complex. A framework is something you need to slot your system into, and it has a lot of twists and turns so it ends up restricting how you do all the other things.
There are lots of microservice-foundation-related building blocks. E.g. I use a library somewhere that just does circuit-breaking. I slot that into my app rather than the other way around, and if I wanted to replace it, it's a fairly isolated thing. I don't use any frameworks for it though
Frameworks also tend to grow more and more complex as they evolve. If I as a user want a different auth for example, that needs to be supported by the framework. Over time, all things become pluggable and configurable, until at some point it's complex enough that someone restarts the process, or makes an opinionated spin of the framework.
