Recommendations for GKE (GCP)

20 March 2023 · Read time 1 min

Machine Types

NOTE: Depending on machine types & number of instances you plan to use, you may need to request GCE quota increase.

• Quota page link https://console.cloud.google.com/iam-admin/quotas?project=your-project-name-here

From the table, filter on the Quota (example: persistent Disk SSD) and Dimensions (example: specify the region name us-west1) columns, select EDIT QUOTAS then change the Limit value (example: change 500 GB to 600 GB).

Property name filter example

• Persistent Disk SSD (GB)
• N2 CPUs
• us-west1

Altinity recommends setting up each node pool except the default one in at least 3 zones.

If you plan on sharing Kubernetes cluster with other workloads, it’s recommended you label Kubernetes Nodes intended for Altinity.Cloud Anywhere with altinity.cloud/use=anywhere & taint with dedicated=anywhere:NoSchedule.

for Zookeeper and infrastructure nodes

• e2-standard-2

for ClickHouse nodes

It’s recommended to taint node pools below with dedicated=clickhouse:NoSchedule (in addition to altinity.cloud/use=anywhere).

• n2d-standard-2
• n2d-standard-4
• n2d-standard-8
• n2d-standard-16
• n2d-standard-32

If GCP is out of n2d-standard-* instances in the region of your choice, we recommend substituting them with n2-standard-*.

Storage Classes

• standard-rwo
• premium-rwo

GKE comes pre-configured with both.
