Re: [Wikitech-l] eqiad kubernetes cluster upgrade on 2021-03-23

Hello everyone, TL;DR if you are not deploying services to the eqiad kubernetes cluster, you can safely skip this. Long version: After having tested thrice our cluster reinitialization procedure, next week, on Tuesday 2021-03-23 we will be reinitializing our eqiad kubernetes cluster. All traffic will be drained from it beforehand and we expect no user visible impact. However, for the duration of the process, the kubernetes eqiad cluster will be unavailable to deployers and thus efforts to deploy to it will fail or worse, not have the expected outcomes. This is normal until SRE serviceops announces that the cluster is fully operational again. SRE service-ops will be deploying all services before marking the cluster as usable and pooling traffic back to it, so there will be no need for deployers to re-deploy their services. For your convenience the list of services that are currently deployed on that cluster is: apertium api-gateway blubberoid changeprop changeprop-jobqueue citoid cxserver echostore eventgate-analytics eventgate-analytics-external eventgate-logging-external eventgate-main eventstreams eventstreams-internal linkrecommendation mathoid mobileapps proton push-notifications recommendation-api sessionstore similar-users termbox wikifeeds zotero Regards, -- Alexandros Kosiaris Principal Site Reliability Engineer Wikimedia Foundation
