Google Cloud Fundamentals: Getting Started with GKE
In this lab, you create a Google Kubernetes Engine cluster containing several containers, each containing a web server. You place a load balancer in front of the cluster and view its contents.
- In the Google Cloud Console, on the Navigation menu (
), click APIs & Services.
- Scroll down in the list of enabled APIs, and confirm that both of these APIs are enabled:
- Kubernetes Engine API
- Container Registry API
If either API is missing, click Enable APIs and Services at the top. Search for the above APIs by name and enable each for your current project.
Use “gcloud config set project [PROJECT_ID]” to change to a different project.

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` flagDefault 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). Creating cluster webfrontend in us-east5-c...

In this lab, we configured a Kubernetes cluster in Kubernetes Engine. We populated the cluster with several pods containing an application, exposed the application, and scaled the application.
