I'm trying to create a node pool with machines booting from a SSD with gcloud. If I tried creating a compute instance I would use the --boot-disk-type option to specify that, yet there seems to be no such option when creating a node pool.
I've checked the documentation on creating node-pools and tried to specify the --boot-disk-type option anyway like so:
gcloud container node-pools create test-pool --cluster=my-cluster --machine-type=n1-highcpu-4 --disk-size=50 --num-nodes=2 --boot-disk-type=pd-ssdBoth without success. So my question is, whether it is even possible to create a node pool with machines booting from SSD. Maybe I'm trying to do it the wrong way. If this is not supported, what could be a possible workaround to get a node pool with machines booting from SSD?
I'm aware that I can add local SSDs to the machines using the --local-ssd-count option. Yet this does not seem to solve my problem.
This option is supported now. You can specify boot disk type and size for node pools.
--disk-type=DISK_TYPE
Type of the node VM boot disk. Defaults to pd-standard. DISK_TYPE must be one of: pd-standard, pd-ssd.
--disk-size=DISK_SIZE
Size for node VM boot disks. Defaults to 100GB.https://cloud.google.com/sdk/gcloud/reference/container/node-pools/create
There isn't currently an option to specify the boot disk type for a node pool. The options you can specify about nodes are documented in the NodeConfig struct in the Google Container Engine API.
As an aside, for fields that exist in a managed instance group but not in the Google Container Engine API you can use the workaround posted here but beware that your changes will not be "sticky" across node version upgrades.
