Enroll Now What is kubernetes? – Kubernetes is a tool developed by google to manage a high availablity of a application  – its is developed on a same genetics as borg and omega on which Google runs its higly scalable application – in days when there is an intro to contanerised world and we were to spin up our infra / app using containers in a matter of sec for DEV & QA environments,   there was a question to manage these containers in a complex environment like PROD – Kubernetes comes in picture then and perfectly fits in this secenerio and manages the containers in a efficient manner including networking, securities aspects Why Kubernetes?– There is a time when its difficult to manage a containers in a complex environment like PROD – here comes the kubernetes which ease the infra complexity. – it help to provide a highly scalable environment with a minimum downtime – it also makes easier to establish the effective networking communications between the different nodes & pods. How Kubernetes works? Kubernetes has below main components in its architecture. MASTER :   a. Apiserver : It is the main front end component of kubernetes.We can say its a bridge that is connecting all components within kubernetes it has many or all services of kubernetes which makes an API call according to the service type to get & send requests.  b. ETCD      : its a database which stores all data in the form of key value pair.it has all the informations stored related to the kubernetes cluster       c. Controller: it is the component in master node which always keeps an eye for all services.it runs in a loop and always keeps track of service like nodes, endpoints, replicas etc .if anything is not up to date as per the required desired state it sends those infor to api server which inturns talks to etcd and scheduler.  d. Schedular:  this component basically schedule all the required service as per the desired state .Apiserver when recieve anything from controller then it sends requests to schedular to schedule the jobs to the worker nodes. WORKER NODES:   a. Kubelet:    its is the agent running on worker nodes to register them with the cluster.it serves the requests coming from scheduler via apiserver  b. container runtime: any contanerised tool like docker to run containers    c. kube-proxy :  to estabilish a networking within kubernetes cluster What is POD?– Pod is a tiny atomic object running on master/worker nodes to have running container  – it is instantiated when scheduler schedules anything – each pod will get a unique IP and containers inside a pod may have different IP’s but in truth will have same IP of that pod- all containers inside a POD shares the same IP – all containers within a pod can communicate via localhost How certifcations based auth works ??  Write a diff between Create vs Apply and Put Vs Post and define IDEOMPOTENCY? Kubernetes create will allow us to create objects in kubernetes and will throw error if the object is already present. Kubernetes apply allow us to create a object if not present
