uWSGI: Using emperor mode, register internal routing rules for vassals

Question

I am using uWSGI to deploy python wsgi microservices.

My architecture looks like :

• Emperor => handles routing of all request starting by /api
• Vassal "users" => handles request on /api/users
• Vassal "payments" => handles request on /api/payments
• etc.

The routing is handled by the emperor using internal routing rules.

My problem is that routing rules are statically defined in the emperor configuration file.

1/ Is there any way for a vassal to "dynamically" (= on startup) add rules to the emperor internal routing table ?

2/ If not, is there any way for an emperor to "get" routing rules from the vassal when starting it ?

Answer 1

Emperor's purpose is managing processes (vassals), the 'routing' concept is the job of 'corerouters' (fastrouter, httprouter, sslrouter, rawrouter). For your case the subscription system could be the best solution:

in 2.1 (current github master) there is the possibility to subscribe 'by mountpoint'
