The service that stores the virtual machine (VM) image in OpenStack is Glance91011.Glance is the image service in OpenStack that allows you to discover, register, retrieve, and store virtual machine images

The two primary ways used to manage objects by kubectl are imperative commands and declarative object configuration10. Imperative commands operate directly on live objects in a cluster.The user provides operations to the kubectl command as arguments or flags10. Declarative object configuration specifies the operation (create, replace, etc.), optional flags and at least one file name.The file specified must contain a full definition of the object in YAML or JSON format10.

The name of the Docker container runtime is containerd, which is a daemon that manages the complete container lifecycle of its host system, from image transfer and storage to container execution and supervision to low-level storage to network attachments and beyond. Dockerd is the Docker daemon that acts as the primary user interface for Docker. Docker cl is not a valid name for any Docker component.Cri-o is another container runtime that implements the Kubernetes Container Runtime Interface (CRI) to enable using OCI (Open Container Initiative) compatible runtimes

This manifest is used to create a deployment, which is a Kubernetes resource that manages a set of pods with the same configuration. A deployment can also provide declarative updates, scaling, and rolling back for the pods. The created pods are not receiving traffic on port 80, because the manifest does not specify a service or a selector for the deployment. A service is another Kubernetes resource that defines a logical set of pods and a policy to access them. A selector is a label query that matches the pods that belong to the service.Four pods are created as a result of applying this manifest, because the manifest specifies replicas: 4 in the spec section of the deployment
