# WhatTheHack039
This project contains the reference solutin.
## Requirements
* Azure subscription
* Contributor permissions on this subscription
* The following tools
* az (Azure CLI)
* terraform
* kubectl
* helm
* kubelogin
## Installation
The infrastructure is defined in Terraform, a descriptive Infrastructure-as-Code technology. The infrastructure is provisioned in two stages
* Azure
* Kubernetes
Azure contains the whole Azure parts and includes a Azure Kubernetes Service (AKS). The second stage provisions resources in the AKS.
### Install the Azure part
Go to the Azure directory. Login to Azure, either
```shell
az login
```
for human login or
```shell
az login --service-principal -u -p
```
in case you have a service principal. Switch to the right subscription using
```shell
az account set --subscription
```
And then run
```shell
terraform init
```
to install all Terraform providers and modules. After that create the infrastructure running
```shell
terraform apply
```
Terraform will create a plan that you can confirm by typing "yes" upon question. You will find the following resource groups in the subscription
* hackXXXX
* hackXXXX-aks-resources
In the subscription hackXXX you will find the following:
Terraform automatically loads the credentials to your local kubectl environment. So this command should work:
```
$ kubectl version ✔ hack8661 ⎈
Client Version: v1.28.2
Kustomize Version: v5.0.4-0.20230601165947-6ce0bf390ce3
Server Version: v1.27.3
```
and
```bash
$ kubectl get nodes ✔ hack8661 ⎈
NAME STATUS ROLES AGE VERSION
aks-exnodepool-29187889-vmss000000 Ready agent 2d17h v1.27.3
```
### Install the Kubernetes part
Go to the Kubernetes directory. We need to define the value for the variable email_adress like so
```bash
echo email_address= >terraform.auto.tfvars
```
This file is picked automatically and is ignored by git. Run
```shell
terraform init
```
and then
```shell
terraform apply
```
again, confirm with "yes" when asked.
### Verify the result
You should be able to see the following
* ingress-nginx is installed
* The ingress-nginx has a public IP address
* cert-manager is installed
* Clusterissuer "letsencrypt-prod" (with your email address)
* kube-prometheus-stack installed
* Namespace "hack"
* Deployment "api"
* Reading the secrets for SQL_SERVER_PASSWORD from the KeyVault
* Horizonal Pod Autoscaler
* Persitent Volume Claim of type RWX which uses a file share on a storage account
* Ingress using traefik.me
* Certificate issued by Let's Encrypt
* Deployment "web"
* Horizional Pod Autoscaler
* Ingress using traefik.me
* Certificate issued by Let's Encrypt
### Tearing down
Run the command
```shell
terraform destroy
```
first in the Kubernetes, then Azure parts (reverse order)
