Lab Exercise: Automating Network Deployment with Terraform

Lab Overview

In this final lab, you will use Terraform to automate the creation of a VNet and subnet as IaC, building on previous concepts for repeatable deployments.

GitOps with ArgoCD

Argo CD is an open-source GitOps continuous delivery tool. It monitors your cluster and your declaratively-defined infrastructure stored in a Git repository and resolves differences between the two — effectively automating an application deployment.

In this lab you will:

Create an all-in-one Kubernetes cluster on the Ubuntu VM
Install kubectl
Deploy Argo CD
Configure Argo to monitor a GitHub project

Creating a GitHub Personal Access Token

Go to your GitHub profile and click on Settings.
In the left sidebar, click on Developer settings.
Click on Personal access tokens.
Click on Generate new token.
Give the token a descriptive name.
Select the scopes you need for the token (e.g., repo, read:user, user:email).
Click on Generate token.
Copy the token to your clipboard.

To create a Kops cluster

Install AWSCLI

pip install awscli

Add to path

export PATH=~/.local/bin:$PATH

Kubeadm expose Dashboard

Deploy dashboard

kubectl apply -f https://raw.githubusercontent.com/kubernetes/dashboard/v1.10.1/src/deploy/recommended/kubernetes-dashboard.yaml

List tokens

Confirm a kubernetes-dashboard service account token was created
