Hello,
The Data Platform SRE team needs to carry out an upgrade of our
*dse-k8s-eqiad* Kubernetes cluster, which will require some downtime for
services hosted on this cluster.
If you don't use any of these services, you can ignore the rest of this
message.
* Airflow
* DataHub
* GrowthBook
* Flink
* Spark History
* Superset
* Test Kitchen
These services will, unfortunately, require downtime while the
Kubernetes upgrade is in progress.
The maintenance window, during which we will carry out the upgrade is
this *Thursday March 26th, between 10:30 and 15:00 UTC*.
Some of our dse-k8s workload is already available in a multi-dc capacity
on the *dse-k8s-codfw* cluster, so will *not* require downtime.
Specifically, these are our OpenSearch on Kubernetes clusters for:
* opensearch-ipoid
* opensearch-semantic-search
We will be keeping this ticket updated throughout the maintenance
window, on our progress:
T414484 Upgrade DSE clusters to kubernetes 1.31
<https://phabricator.wikimedia.org/T414484>
Once the Airflow services are running again, we will be working with
representatives from the Data Engineering team to ensure that all data
pipeline tasks have been addressed.
If you have any queries, comments, or concerns, please don't hesitate to
share them with us.
You can get in touch with us by reply to this message, or via
#data-platform-sre on Slack, or #wikimedia-data-platform on IRC.
Kind regards,
Ben
