Google HOWTO for GKE k8s cluster creation
Create GKE cluster in GCP
Enable Google Kubernetes Engine in a Cloud project
For access to Google Kubernetes Engine, select or create a Cloud project to work in, then enable the required APIs:
- to ensure that you have the permissions you need, or select an existing project in which you have the
relevant permissions. - The necessary APIs are enabled:
- Kubernetes Engine API
- Artifact Registry API
Create a GKE cluster
Click the Navigation menu
icon, then Kubernetes Engine. You can see where it is by clicking the following button:
Click
Clusters Click
Create Choose Standard mode and click
Configure In the
Name hello-cluster.Under Location type, select
Zonal Zone us-west1-a.Click
Create
Deploy the sample app to GKE
Click
Workloads Click
Deploy In the Edit container section, select
Existing container image In the Image path field, click
Select In the
Select container image hello-appimage you pushed to Artifact Registry.Click
Select Click
Done Click
Continue In the Configuration section, under Labels, enter
appfor Key
andhello-appfor Value.Under the Configuration section, click the
View YAML Click
Close Click
Deploy When the Deployment Pods are ready, the Deployment details page opens.
Under
Managed pods hello-appDeployment.
Expose a sample app to the internet
Click
Workloads Click on hello-app in the
Name From the Deployment details page, click the
Actions > Expose In the Expose dialog, under the
Port Mapping Target port 8080.Service type
Click
Expose hello-app.When the Load Balancer is ready, the Service details page opens.
Scroll down to the Exposing services secion and copy the external IP from the
Endpoints - Note that Endpoints are used as External IP addresses for the next sections.
Click Next to learn how to deploy a new version of your app.
🎉 Success
You have successfully deployed a containerized web application!
Clean up
To avoid incurring charges to your Google Cloud account for the resources used in this tutorial, delete your project if you're not going to use it again. If you intend to use it again, you can delete the individual resources.
Delete the project
To delete the Cloud project:
Delete individual resources
Delete the Service: This deallocates the Cloud Load Balancer created for your Service:
Delete the cluster: This deletes the resources that make up the cluster. Replace COMPUTE_ZONE in the command below with your own zone:
Delete your container images: This deletes the Docker images you pushed to Artifact Registry. Replace PROJECT-ID with your own:
