To run a container in a Kubernetes environment, you should define a YAML manifest for the container and its resources2. YAML manifests are used to define Kubernetes objects, such as pods or services.These manifests describe the desired state of the system2.

The default container runtime engine used by OpenShift is cri-o. CRI-O is an open source, community-driven container engine.Its primary goal is to replace the Docker service as the container engine for Kubernetes implementations, such as OpenShift Container Platform3.

Juniper Cloud-Native Contrail Networking (CN2) can be integrated with Kubernetes.CN2 is optimized for Kubernetes-orchestrated environments and can be used to connect, isolate, and secure cloud workloads and services seamlessly across private, public, and hybrid clouds.

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

Keystone is an OpenStack service that provides API client authentication3456.It provides API client authentication, service discovery, and distributed multi-tenant authorization by implementing OpenStack's Identity API

The Kubernetes object definition file is in YAML format789.Kubernetes objects are represented in the Kubernetes API, and you can express them in .yaml format7.You can executekubectl get deployment <deployment-name> -o yamlto get the deployment definition in a yaml format8.

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 cloud computing feature that automatically increases or decreases the resources based on the demand is known as rapid elasticity1112.In cloud computing, scaling is the process of adding or removing compute, storage, and network services to meet the demands a workload makes for resources in order to maintain availability and performance as utilization increases11.

The openstack user list command uses the Keystone service, which is the identity service for OpenStack. Keystone provides authentication, authorization, and service discovery for OpenStack.It also manages projects, users, roles, and endpoints for the OpenStack services
