How certificate based Authentication works? explain in kubernetes context A: User/administrator generates a certificate signing request (CSR). Administrator approves the request and signs it with their CA. Administrator provides the resulting certificate back to the user. User presents their key and certificate pair to prove their identity. Admin creates private key –> which is later converts into csr–> Admin later take this csr file and create .crt file. .crt file can be downloaded by user using csr api to confirm identity.

How certificates are used by your cluster– Kubernetes uses client certificates, bearer tokens, an authenticating proxy, or HTTP basic auth to authenticate API requests through authentication plugins– Client certificates generated by kubeadm expire after 1 year.– By default, kubeadm generates all the certificates needed for a cluster to run. You can override this behavior by providing your own certificates.– you must place them in whatever directory is specified by the –cert-dir flag or the certificatesDir field of kubeadm’s ClusterConfiguration. By

What is programming Languages …? programming languages are the tools that we use to write instructions for computer to follow. Computers can think in binary strings of 1s and 0s. Programming languages allow to translate the 1s and 0s into simple language that humans can understand and write. A programming language is made up of a series of symbols that serves as a bridge that allow humans to translate our thoughts into instructions computers can understand. Use of Programming Language…?

What is kubernetes Service?

How to work with ReplicasSets?ReplicaSet helps bring up a new instance of a Pod when the existing one fails,scale it

Assignment – 1 What is ReplicasSets? A: A ReplicaSet ensures that a specified number of pod replicas are running at any given time. How to work with ReplicasSets? A: A ReplicaSet is linked to its Pods via the Pods’ metadata.ownerReferences field, which specifies what resource the current object is owned by. All Pods acquired by a ReplicaSet have their owning ReplicaSet’s identifying information within their ownerReferences field. It’s through this link that the ReplicaSet knows of the state of the Pods it is

What is ReplicaSets ? A ReplicaSets is a bug fixed version of replica controller and it’s purpose is to maintain a stable set of replica Pods running at any given time. Working with ReplicaSets with example : A ReplicaSet is defined with fields, including a selector that specifies how to identify Pods it can acquire, a number of replicas indicating how many Pods it should be maintaining, and a pod template specifying the data of new Pods it should create
