Brief description of POD creation and deletion

The process of creating a Pod can be divided into the following steps: Users send a request to create a Pod to the API server using the kubectl create command or a YAML file. The API server converts the request into an internal Kubernetes object and sets the Pod’s status to Pending. The scheduler schedules […]
