Deployment pipeline/FAQ

From Wikitech
This page describes the previous deployment pipeline mechanism based on PipelineLib. For information about the current deployment pipeline, which uses GitLab, Blubber, and Kokkuri, see the deployment pipeline documentation on mediawiki.org.

What does this mean for me?

  • If you are currently running a service in production, we'll talk to you about migration to kubernetes.
  • If you are building a new service to go into production, please contact us to make sure your service is "born kubernetes", rather than having to migrate a month after deployment.
  • If you don't have or plan to have a service, don't worry about things for now. Changes to non-services will take a while.

How can I view application logs from my service in production Kubernetes?

These logs are available in Logstash#Kibana. This dashboard should allow you to select your service (and optionally Kubernetes cluster) to view logs.
