We are back again with some quick tips including Q/A and blog posts on the topics that we covered in the
Live sessions which will help you to clear Kubernetes Certifications [CKA/D] and get a better-paid job in the field of Microservices, Containers, DevOps & Kubernetes.Ingress Controller
A Kubernetes Ingress controller is a load balancer designed specifically for Kubernetes environments. For managing containerized systems, Kubernetes has become the de-facto standard. Moving production workloads to Kubernetes adds new obstacles and complexities to application traffic management for many businesses.
The ingress controller will accept traffic from outside the Kubernetes network and distribute it to pods (containers) running on the platform. It can handle egress traffic within a cluster for services that need to talk to other services outside of the cluster. Ingress controllers are used to deploying artifacts known as “Ingress Resources” using the Kubernetes API.
To Know More on Ingress controller
Q1) How does the ingress controller work?
Ans: Ingress Controller is an intelligent Load Balancer. Ingress is a high-level abstraction responsible for allowing a simple host or URL-based HTTP routing. It is always implemented using a third-party proxy. These implementations are nothing but Ingress Controller. It is a Layer-7 load balancer.

Q8) What are the main terminologies for Helm?
Ans:
- A Chart is a Helm package. It contains all of the resource definitions necessary to run an application, tool, or service inside of a
Kubernetes cluster. - A Repository is a place where charts can be collected and shared.
- A Release is an instance of a chart running in a Kubernetes cluster.
Q9) Explain Helm Architecture?
Ans: Helm Kubernetes has two parts, the client(CLI) and the server(Tiller), it works on a client-server model.
- Tiller: Helm manages the Kubernetes application through a component called Tiller, a Server installed within the Kubernetes cluster. Tiller interacts with the Kubernetes API server to install, upgrade, query, and remove Kubernetes resources. But for development, it can also be run locally and configured to talk to a remote Kubernetes cluster.
- Client(CLI): So, the client lives on the local workstation and the server on the Kubernetes cluster to execute what is needed. Think of CLI is used to push the resources you need and the Tiller runs inside of the Kubernetes cluster and manages (creating/updating/deleting) resources of the helm charts.
