hello

With the huge shift in the technological world, from running servers on local premises to the cloud, the need for containerization has increased. Kubernetes is a powerful open-source platform to manage containers and their services. This course provides an understanding of Docker and Kubernetes.

You will start with the basics of Docker and an introduction to containers and images. Next, you'll learn to create Dockerfile for building images. Then, you’ll learn about Kubernetes, Kubernetes clusters, nodes, and their working. You will finish this course by setting up your own Kubernetes cluster on top of Azure and using the Helm chart to manage it.

In the 4 years (2015-2019), Kubernetes job searches grew by 2,125% and are continuing to grow. Therefore, understanding the basics of Kubernetes, its architecture, and its working would help you land roles like that of a DevOps engineer and a cloud architect.

Running Kubernetes Cluster using Azure Kubernetes Service

The following steps can be used to enable network access to an application on the AKS cluster.

# Create the service manifest file

We first need to create a server manifest file. The steps involved are described below.

## Step 1: Create a YAML file
Create a YAML file using the command `touch service.yaml`.

## Step 2: Specify the `apiVersion` and `kind`

We need to specify the `apiVersion` and `kind` attributes for the manifest that we create. The `name` is the name of the service.

#service.yaml
apiVersion: v1
kind: Service
metadata:
  name: static-edu-website

## Step 3: Specify the service type and selectors

Using the `type` key, we need to specify the Kubernetes service we want to use. We can also add some labels using the `selector` key. In this case, we are adding the label `static-edu-website`.
