MediaWiki On Kubernetes
MediaWiki-on-Kubernetes (or mw-on-k8s for short) is an initiative to transition the MediaWiki at WMF deployment from dedicated Application servers to Kubernetes. This page contains information about what is changing as part of this transition.
"This migration will unleash the ability to deploy multiple versions of code simultaneously. Also, this will help enhance platform capabilities to build dockerized isolated environments for coding, testing and even production debugging.
MediaWiki on Kubernetes will allow us to deprecate and eventually remove a lot of our in-house developed code. Another benefit is that we will be able to react to sudden traffic spikes, like newsworthy events better, as the flexing up and down is a matter of configuration change. This enables efficient placement of workloads, packing workloads in a more environmentally friendly way, increasing hardware utilization."[1]
MediaWiki on Kubernetes is deployed to both the main Eqiad and Codfw datacenters, in the wikikube kubernetes clusters. While the situation is in constant evolution, we currently have the following server groups:
