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

# Installing Helm
Run the following commands to install Helm on your system:


curl https://baltocdn.com/helm/signing.asc | sudo apt-key add -
sudo apt-get install apt-transport-https --yes
echo "deb https://baltocdn.com/helm/stable/debian/ all main" | sudo tee /etc/apt/sources.list.d/helm-stable-debian.list
sudo apt-get update
sudo apt-get install helm

You can try out these commands in the terminal below.

# How to use Helm repository

A Helm repository stores information on Helm charts. We can configure Helm repositories with the Helm client for it to install charts from a repository using the `helm repo add` command. Run the command `helm repo add azure-marketplace https://marketplace.azurecr.io/helm/v1/repo`.

We need to manually update the cache periodically in order to fetch the repository’s latest information. We can update using the command `helm repo update`. To search for charts on all locally added Helm repositories, we can run the command `helm search repo`.
