Understand kubectl to manage Kubernetes objects

kubernetesresourcesUse kubectlto interact with Kubernetes resources, such as Pod, Services, Volumes, and more. When you use kubectl commands, you are querying or setting the desired state of the cluster. kubectlis calling into the API and manipulating or getting status from the primitives.

In this post, learn about the important resources that developers use and how you go about getting information about and creating a resource using kubectl.

Read and write Kubernetes objects using kubernetes.io API reference documentation

Once you have deployed your Kubernetes infrastructure, you have a control plane and a worker plane. You define how you want Kubernetes to manage your Kubernetes objects through tools that interact with the API. Kubernetes objects are all those persistent entities in the Kubernetes system, such as your Pods, Nodes, Services, Namespaces, ConfigMaps, Events.

Most operations can be performed through the kubectl command-line interface or other command-line tools, such as kubeadm, which in turn use the API.

kubectl is the command-line tool where you run most of the commands to manage the Kubernetes clusters. Use kubectl to deploy applications, inspect and manage cluster resources, and view logs.

In this post, learn how to use the Kubernetes documentation to discover the objects, how to figure out to describe the state you want for your Kubernetes objects. In particular, you will want to know the fields to use in your .yaml files and how to determine what the default values are. You will also learn the basic kubectl commands.
