Create a GKE cluster

Goal: Create a GKE cluster.

This workshop uses GKE cluster with most of the default configuration settings. To create an GKE cluster with a regional cluster with a multi-zone node pool, please refer to GKE doc

Prerequisite Tasks

  • Ensure that you have enabled the Google Kubernetes Engine API.

api engine

https://cloud.google.com/kubernetes-engine/docs/quickstart

  • Ensure you have installed the Cloud SDK

  • Ensure you set up default gcloud settings using one of the following methods:

    Using gcloud init, if you want to be walked through setting defaults. Using gcloud config, to individually set your project ID, zone, and region.

    gcloud init                                                                    
Welcome! This command will take you through the configuration of gcloud.

    Then be sure to authorize gcloud to access the Cloud Platform with your Google user credentials:

    gcloud auth login

    Next set a default compute region and compute zone:

    gcloud config set compute/region us-east1

    Set a default compute zone:

    gcloud config set compute/zone us-east1-b

  • Export your gcloud settings for next steps:

    REGION=us-east1
# Persist for Later Sessions in Case of Timeout
echo export REGION=us-east1 >> ~/.bashrc

LOCATION=us-east1-b
# Persist for Later Sessions in Case of Timeout
echo export LOCATION=us-east1-b >> ~/.bashrc

CLUSTERNAME=gke-calicocloud-workshop
# Persist for Later Sessions in Case of Timeout
echo export CLUSTERNAME=gke-calicocloud-workshop >> ~/.bashrc

Steps

  1. Create a GKE cluster for this workshop.
gcloud container clusters create $CLUSTERNAME \
--region $REGION \
--node-locations $LOCATION \
--addons HorizontalPodAutoscaling,HttpLoadBalancing,GcePersistentDiskCsiDriver \
--num-nodes 3 \
--enable-intra-node-visibility \
--machine-type e2-standard-4

  1. Getting credentials for your new cluster.

    gcloud container clusters get-credentials $CLUSTERNAME --region $REGION

  2. Confirm nodes are ready status in your cluster.

    kubectl get nodes

  3. Download this repo into your environment:

    git clone https://github.com/tigera-solutions/calicocloud-kaas-workshop-demo.git

cd calicocloud-kaas-workshop-demo

  4. [Optional] scale your node group as desired count.

    gcloud container clusters resize $CLUSTERNAME --zone=$LOCATION --num-nodes=3

Next steps

You should now have a Kubernetes cluster running with 3 nodes. You do not see the master servers for the cluster because these are managed by GCP. The Control Plane services which manage the Kubernetes cluster such as scheduling, API access, configuration data store and object controllers are all provided as services to the nodes.
