We introduced highly available masters for Google Kubernetes Engine earlier this fall with our alpha launch of regional clusters. Today, regional clusters are in beta and ready to use at scale in Kubernetes Engine.
Regional clusters allow you to create a Kubernetes Engine cluster with a multi-master, highly available control plane that helps ensure higher cluster uptime. With regional clusters in Kubernetes Engine, you gain:
When you create a regional cluster, Kubernetes Engine spreads your masters and nodes across three zones in a region, ensuring that you can experience a zonal failure and still remain online.
By default, Kubernetes Engine creates three nodes in each zone (giving you nine total nodes), but you can change the number of nodes in your cluster with the
Creating a Kubernetes Engine regional cluster is simple. Let’s create a regional cluster with two nodes in each zone.
$ gcloud beta container clusters create my-regional-cluster --region=us-central1 --num-nodes=2
Or you can use the Cloud Console to create a regional cluster:
For a more detailed explanation of the regional clusters feature along with additional flags you can use, check out the documentation.
Kubernetes Engine regional clusters are offered at no additional charge during the beta period. We will announce pricing as part of general availability. Until then, please send any feedback to firstname.lastname@example.org.
This week the Kubernetes community gathers in Austin for the annual #KubeCon conference. The Google Cloud team will host various activities throughout the week. Join us for parties, workshops, and more than a dozen talks by experts. More info and ways to RSVP at g.co/kubecon.
