Cluster orchestration with Google Kubernetes Engine
List of advanced cluster management features that Google Cloud provides:
Load balancing for Compute Engine instances
Node pools to designate subsets of nodes within a cluster for additional flexibility
Automatic scaling of your cluster's node instance count
Automatic upgrades for your cluster's node software
Node auto-repair to maintain node health and availability
Logging and Monitoring with Cloud Monitoring for visibility into your cluster
Activate Cloud Shell
Cloud Shell is a virtual machine that is loaded with development tools. It offers a persistent 5GB home directory and runs on the Google Cloud. Cloud Shell provides command-line access to your Google Cloud resources.
Welcome to Cloud Shell! Type "help" to get started.
Your Cloud Platform project in this session is set to qwiklabs-gcp-02-40d87254d20c.
Use “gcloud config set project [PROJECT_ID]” to change to a different project.

Create a GKE cluster

Default change: VPC-native is the default mode during cluster creation for versions greater than 1.21.0-gke.1500. To create advanced routes based clusters, please pass the `--no-enable-ip-alias` flag
Default change: During creation of nodepools or autoscaling configuration changes for cluster versions greater than 1.24.1-gke.800 a default location policy is applied. For Spot and PVM it defaults to ANY, and for all other VM kinds a BALANCED policy is used. To change the default values use the `--location-policy` flag.
Note: Your Pod address range (`--cluster-ipv4-cidr`) can accommodate at most 1008 node(s).
