Caution
You're viewing documentation for an unstable version of ScyllaDB Operator. Switch to the latest stable version.
Deploying ScyllaDB on GKE¶
This is a quickstart guide to help you set up a basic GKE cluster quickly with local NVMes and solid performance.
This is by no means a complete guide, and you should always consult your Kubernetes provider’s documentation.
Creating a GKE cluster¶
First, we need to create a kubelet config to configure static CPU policy:
cat > systemconfig.yaml <<EOF
kubeletConfig:
cpuManagerPolicy: static
EOF
Then we’ll create a GKE cluster with the following:
gcloud container \
clusters create 'my-k8s-cluster' \
--zone='us-central1' \
--cluster-version="latest" \
--machine-type='n2-standard-8' \
--num-nodes='2' \
--disk-type='pd-ssd' --disk-size='20' \
--image-type='UBUNTU_CONTAINERD' \
--enable-stackdriver-kubernetes \
--no-enable-autoupgrade \
--no-enable-autorepair
and then we’ll create a dedicated pool with NVMes for ScyllaDB
gcloud container \
node-pools create 'scyllaclusters' \
--zone='us-central1' \
--cluster='my-k8s-cluster' \
--node-version="latest" \
--machine-type='n2-standard-16' \
--num-nodes='4' \
--disk-type='pd-ssd' --disk-size='20' \
--local-nvme-ssd-block='count=4' \
--image-type='UBUNTU_CONTAINERD' \
--system-config-from-file='systemconfig.yaml' \
--no-enable-autoupgrade \
--no-enable-autorepair \
--node-labels='scylla.scylladb.com/node-type=scylla' \
--node-taints='scylla-operator.scylladb.com/dedicated=scyllaclusters:NoSchedule'
Installing Kubernetes prerequisites¶
xfsprogs¶
Beginning with GKE version 1.32.1-gke.1002000, the Ubuntu image used by GKE clusters no longer provides the xfsprogs package by default.
This package is required to format the local NVMe disks used by ScyllaDB. Please refer to the xfsprogs section of the Kubernetes prerequisites page for more details.
Deploying ScyllaDB Operator¶
To deploy ScyllaDB Operator follow the installation guide.
Creating ScyllaDB¶
To deploy a ScyllaDB cluster please head to our dedicated section on the topic.
Accessing ScyllaDB¶
We also have a whole section dedicated to how you can access the ScyllaDB cluster you’ve just created.
Deleting a GKE cluster¶
Once you are done with your experiments you can delete your cluster using the following command:
gcloud container clusters delete --zone='us-central1' 'my-k8s-cluster'
