Migrate internal traffic to k8s
Closed, ResolvedPublic
Actions

Description

We need to progressively migrate traffic from our services to call the api in the mw-api-int cluster on k8s.

Right now we have (via this thanos query:

  • Mobileapps making 3k rps to the mediawiki API (!!!) <- Moved in 2nd stage
  • restbase making 600 rps <- Moved in 2nd stage
  • ores making 75-100 rps <- Deprecated
  • wikifeeds making ~ 70 rps <- Moved in 2nd stage
  • flink making ~ 40 rps <- Moved in 2nd stage

Everything else is basically marginal.

I propose we start moving all services on kubernetes to use mw-api-int now, with the exception of the ones named above.

Looks like this is now done except for "some straggling traffic" for the api-gateway?

Yes, but I will close it when I'm sure I have zero internal traffic on the bare metal clusters.

hnowlan subscribed.EditedJun 13 2024, 3:56 PM

I believe the straggling traffic here is a misnomer/a graph misunderstanding - the API gateway's envoy config refers to traffic to the mediawiki API as "mwapi_cluster" internally before and after the hostname was changed. I believe these requests are normal and are being routed to k8s already - drop mwapi_cluster from the graph and we're at zero! 🎉

All internal traffic has been migrated.
