Manage Kubernetes Cluster with Terraform and Web APP Example

In this project I'm demonstrating you how to use Terraform together to create and manage the Kubernetes cluster on Kind.

Prerequisites

Terraform CLI installed
Docker

Getting Started

These commands will get a Cluster with 3 nodes

First, clone the repo:

$ git clone https://github.com/mateusclira/challenge-cloud-engineer.git
$ cd challenge-cloud-engineer

Then initialize Terraform config:

terraform init

Review the actions plan:

terraform plan

Run the Terraform actions:

terraform apply

https://artifacthub.io/packages/helm/ingress-nginx/ingress-nginx

You have to install the ingress-nginx controler

kubectl apply -f https://raw.githubusercontent.com/kubernetes/ingress-nginx/controller-v1.9.4/deploy/static/provider/cloud/deploy.yaml

Run this to install the cert-manager

https://artifacthub.io/packages/helm/cert-manager/cert-manager

First install the CRDs:

kubectl apply -f https://github.com/cert-manager/cert-manager/releases/download/v1.13.2/cert-manager.crds.yaml

Add the helm repo

helm repo add jetstack https://charts.jetstack.io

Then install the cert-manager:

helm install cert-manager jetstack/cert-manager --namespace cert-manager --create-namespace --version v1.13.2 --set prometheus.enabled=false --set webhook.timeoutSeconds=4

You are going to need to indicate that the your cluster's IP is addressed to your Hostname. To do so, you are going to need a DNS Provider service

Now, apply the Issuer, so it can provide the environment for the Certificate

kubectl apply -f .\kubernetes\issuer.yaml

Deploy the application and the service

kubectl apply -f .\kubernetes\deployment.yaml

kubectl apply -f .\kubernetes\service.yaml

We can now create our Certificate, which will be the last requisite for the Ingress

kubectl apply -f .\kubernetes\certificate.yaml

Make sure your certificate ran correctly and created the tls. You should be able to see a recently created kubernetes.io/tls's TYPE

kubectl get secrets

Finally, create the ingress, and the HTTPS will be available.

kubectl apply -f .\kubernetes\ingress.yaml
