Google Kubernetes Engine is an enterprise-grade platform for containerized applications, including stateful and stateless, AI and ML, Linux and Windows, complex and simple web apps, API, and backend services. It aids you in providing automatic application deployment, scaling and management of Nodes, Pods and Containers.
Go to the Monitors Category View by clicking the Monitors tab. Click on the Kubernetes Engine instance available under Google Cloud in the Cloud Apps section. Displayed is the Google Kubernetes Engine bulk configuration view distributed into three tabs:
By clicking a monitor from the list, you'll be taken to the Google Kubernetes Engine dashboard. It has 4 tabs:
