Docker and Kubernetes - Day-2

The smallest execution unit in Kubernetes is:

• Deployment

• Container

• Pod

• Node

Kubernetes was originally designed and developed by:

• RedHat

• Amazon

• Cloud Native Computing Foundation

• Google

Is the Dockerfile's ENV directive present during the build process?

• No

• Yes

• It depends

Which Kubernetes cluster component stores cluster configuration?

• API Server

• etcd

• kubelet

• Configuration Controller

What is responsible of managing the state of PODs in Kubernetes?

• API Server

• Control Plane

• kubelet

• Container runtime

With new FROM directive in Dockerfile, everything what was done in previous FROM section is:

• copied to final docker image

• discarded completely

• it depends

• only compiled binary is automatically copied to final image

What happens when a control/master node in Kubernetes fails?

• All existing PODs will be terminated

• You can not schedule new PODs

• You can still schedule new PODs because the kubelet still works on all nodes

• All existing PODs will go to hung state

The short for of Kubernetes name is:

• kubernet

• kubelet

• k8s

• kubectl

In a multi-container Pod, what will be the IP addresses of individual Containers?

• The same for all containers

• Each container will get individual IP address

• Only containers which listen on certain port will get individual IP address

• You have to specify which container will get the first IP address

How are Pod names created by Deployment?

• <ReplicaSet>-<Deployment>-<randomString>

• <Deployment>-<ReplicaSet>-<randomString>

• <Deployment>-<randomString>

• <ReplicaSet>-<randomString>
