Cloud_Automation_With_Terraform

Practice and Project to Automation Infrastructure (IAC) or (IaaS) using Terraform & Python

STEP: 1

Pre-requisite

• Create AWS free tire account using this link: https://signin.aws.amazon.com/signup?request_type=register

• Install chocolatly on windows (which helps install any software on windows)

• Install Git & VS Code Editor

• Install Terraform

• Install aws CLI

  • To Install git

    choco install -y git 

  

  • To Install VS Code Editor

    choco install -y vscode

  

  • To Install Terraform

    choco install -y terraform

  

  • To Install AWS CLI

    choco install -y awscli

  

Install Chocolatey for Individual Use:

1. First, ensure that you are using an administrativeshell - you can also install as a non-admin, check out Non-Administrative Installation.
2. Install with powershell.exe

NOTE
Please inspect https://community.chocolatey.org/install.ps1 prior to running any of these scripts to ensure safety. We already know it's safe, but you should verify the security and contents of any script from the internet you are not familiar with. All of these scripts download a remote PowerShell script and execute it on your machine. We take security very seriously. Learn more about our security protocols.

With PowerShell, you must ensure Get-ExecutionPolicy is not Restricted. We suggest using Bypass to bypass the policy to get things installed:

• Run Get-ExecutionPolicy. If it returns Restricted, then run Set-ExecutionPolicy AllSigned or Set-ExecutionPolicy Bypass -Scope Process.

Now run the following command:

Set-ExecutionPolicy Bypass -Scope Process -Force; [System.Net.ServicePointManager]::SecurityProtocol = [System.Net.ServicePointManager]::SecurityProtocol -bor 3072; iex ((New-Object System.Net.WebClient).DownloadString('https://community.chocolatey.org/install.ps1'))

3. Paste the copied text into your shell and press Enter.**
4. Wait a few seconds for the command to complete.
5. If you don't see any errors, you are ready to use Chocolatey! Type choco or choco -? now, or see Getting Started for usage instructions.

STEP: 2

1. Create Project Folder (with you desired folder name eg. Terraform_Automation)
2. Open VS editor code
3. Open the Folder which you created.
4. Now go to plugins and add below plugins.
   • HashiCorp Terraform
   • Terraform

6. Choose Create user.

To Sign In as the New IAM User

1. Sign out of the AWS Management Console.
2. Use the following URL format to sign in to the console: https://aws_account_number.signin.aws.amazon.com/console/ Replace aws_account_number with your AWS account ID (without any hyphens).
   For example, if your AWS account ID is 1234-5678-9012, replace aws_account_number with 123456789012.
   For information about how to find your account number, see Your AWS Account ID and Its Alias in the IAM User Guide.
3. Enter the IAM user name and password that you just created.
4. When you're signed in, the navigation bar displays: your_user_name @ your_aws_account_id

How To Generate Access Key

1. Go to the AWS management console, click on your Profile name, and then click on My Security Credentials.
2. Go to Access Keys and select Create New Access Key

STEP: 5

Configure Credentials from command prompts (CLI)

To pass the credentials dynamically to void exposing secrate key and token to the other users

• Setup all your access key, Secret Key, Region, output format, running below command in powershell terminal.

aws configure

STEP: 6

Terraform Support Scripting Lanaguage

• HashiCorp (HCL) Also be known as DSL (Domain Specific Language)

Different types of terraform blocks

• Terraform Block
• Provider Block
• Data Block
• Resource Block
• Module Block
• Variable Block
• Output Block
• Locals Block.

Read this for more info : Terraform_Blocks

STEP: 7

Create Provider Block using HCL in provider.tf file

• Please refer the file provider.tf

This provider block needs to be executed using below command to install all the plug-ins and dependencies related to aws to work on

terraform init

Now Let's Jump into Small tasks to automate and practice
