Azure Infrastructure Operations Project: Deploying a scalable IaaS Web Server in Azure

Submitter: Quyet Nguyen

Introduction

For this project, you will write a Packer template and a Terraform template to deploy a customizable, scalable web server in Azure.

Getting Started

1. Clone this repository

2. Create your infrastructure as code

3. Update this README to reflect how someone would use your code.

Dependencies

1. Create an Azure Account
2. Install the Azure command line interface
3. Install Packer
4. Install Terraform

Instructions

2.1. ✔️ Navigate to your repository

2.2. ✔️ Authenticate to Azure the open Azure portal Bash Cloud Shell to upload project1-tagging-policy.json

2.3. ✔️ Deploy a policy

Create the Policy Definition:

az policy definition create --name 'tagging-policy' --display-name 'deny-creation-untagged-resources' --description 'This policy ensures all indexed resources in your subscription have tags and deny deployment if they do not' --rules ./project1-tagging-policy.json  --mode All

2.4. ✔️ Create the Policy Assignment

az policy assignment create --name 'tagging-policy' --display-name 'deny-creation-untagged-resources' --policy tagging-policy

2.5. ✔️ List the policy assignments to verify

az policy assignment list

2.6. ✔️ Create a Server Image with Packer

✔️ Open Azure portal Bash Cloud Shell then upload server.json

✔️ Create a Server Image using below packer command

packer build server.json

✔️ View Images

az image list

2.7. ✔️ Create the infrastructure with Terraform Template

Go to folder cd project1-IaC/

Our Terraform template will allow us to reliably create, update, and destroy our infrastructure

Customize vars.tf

Variables from vars.tf are called from mains.tf, for example the variable prefix is called as:

${var.prefix}

In vars.tf, the description and value is assigned in the following manner:

variable "prefix" {
  description = "The prefix which should be used for all resources in this example"
  default = "quyetnn-project1"
}

See all variable in vars.tf

2.8. ✔️ Deploy infrastructure

1. Initializing Working Directories

terraform init

2. Create infrastructure plan

terraform plan -out solution.plan

3. Deploy the infrastructure plan

terraform apply "solution.plan"

4. View infrastructure

terraform show

Azure Portal Azuredevops resource created by terraform ✔️ View in Azure Portal

5. Destroy infrastructure (when completed) using clean_resources.sh to delete all resources except Azuredevops resource group

terraform state list | while read line
do 
if [[ $line == azurerm_resource_group* ]]; then
echo $line " is a resource group and will not be deleted!"
else
echo "deleting: " $line
terraform destroy -target $line -auto-approve
fi
done

Using terraform state list command to skip destroying azurerm_resource_group which lab user can not delete it.

6. Delete images(when completed)

az image delete -g Azuredevops -n MyPackerImage

✔️ Output

We will show all of logs for the command below

az policy assignment list
az image list
terraform plan -out solution.plan
terraform apply "solution.plan"
terraform show
