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

## What is a service principal?

**Service principals** are service accounts. They’re different from user accounts. We can create a service principal and give it permissions and roles just like we do for user accounts.

## Creating a service principal

The steps to create a service principal are as follows:

1. Log in to the Azure account.
2. Within the portal, navigate to “Home” > “Directory” > “Azure Active Directory” > “App registrations.”

We are redirected to the “App registration” page.

3. Click the “New registration” tab.
4. Fill in the required details and click “Create.”
5. Copy the application ID and tenant ID for future use.
6. Next, click “Add a certificate or secret.”

We are redirected to the “Client secrets” page.

7. Click “New client secret.”
8. Fill in the required details and click “Add.”

This creates a secret ID. We need to save the secret value because we’ll use it as a password to log in to our Azure account using the CLI.
