Challenge 0: Setup your System

Here is what you will learn 🎯

In this challenge you will learn:

  • What prerequisites are needed for dealing with Kubernetes and Azure Kubernetes Service
  • How to install them

Table Of Contents

  1. Git Version Control
  2. Azure CLI
  3. Kubectl
  4. Helm
  5. Terraform

Git Version Control

The repository is located at GitHub, so - obviously - we'll need a local Git client to interact with the repository. Download and install the appropriate version of Git for you here: https://git-scm.com/download

Azure CLI

We will be using the Azure command line interface to create and interact with resources running in Azure.

To install it, go to https://docs.microsoft.com/cli/azure/install-azure-cli?view=azure-cli-latest and choose your platform.

When finished, login to your Azure account from the command line:

$ az login
You have logged in. Now let us find all the subscriptions to which you have access...

A browser window will open, login to Azure and go back to the command prompt. Your active subscription will be shown as JSON, e.g.:

{
  "cloudName": "AzureCloud",
  "id": "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx",
  "isDefault": false,
  "name": "Your Subscription Name",
  "state": "Enabled",
  "tenantId": "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx",
  "user": {
    "name": "xxx@example.com",
    "type": "user"
  }
}

If you have multiple subscriptions, make sure your are working with the correct one!

$ az account show
{
  "cloudName": "AzureCloud",
  "id": "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx",
  "isDefault": false,
  "name": "Your Subscription Name",
  "state": "Enabled",
  "tenantId": "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx",
  "user": {
    "name": "xxx@example.com",
    "type": "user"
  }
}

If that is not the correct one, follow these steps below:

$ az account list -o table
[the list of available subscriptions is printed]

$ az account set -s <SUBSCRIPTIONID_YOU_WANT_TO_USE>

Kubectl

kubectl is the command line interface for Kubernetes. You will need the tool to interact with the cluster, e.g. to create a pod, a deployment or a service.

If you already have the Azure CLI on your machine, you can just install it using the following command:

az aks install-cli

or refer to the documentation for you specific platform.

Install kubectl on Linux

Install kubectl on macOS

Install kubectl on Windows

Helm

Helm is the package manager for Kubernetes. We will need it for installing several 3rd party components for our solution:

https://helm.sh/docs/intro/install/

Terraform

Terraform is an open-source "infrastructure as code" software tool created by HashiCorp. It is a tool for building, changing, and versioning infrastructure safely and efficiently. We will use terraform to create several PaaS services like Azure SQL Db, CosmosDB etc. in this workshop.
