How do I configure my GKE cluster to use a SSD boot disk instead of the default one

Question

How to specify a GKE cluster to use SSD boot disk instead of the standard?

Answer 1

You can specify the boot disk type, standard or SSD, when you create a new cluster or node pool.

You cannot change the boot disk type of an existing cluster or node pool.

To create a cluster with a custom boot disk, run the following command.

[DISK-TYPE] can be either:

• pd-standard, a standard persistent disk (the default)

• pd-ssd, an SSD persistent disk

gcloud container clusters create [CLUSTER_NAME] --disk-type [DISK_TYPE]

To create a node pool in an existing cluster:

gcloud container node-pools create [POOL_NAME] --disk-type [DISK_TYPE]

For example, the following command creates a cluster, example-cluster, with the SSD persistent disk type, pd-ssd:

gcloud container clusters create example-cluster --disk-type pd-ssd
