21+
mkdir /Users/<YOUR-USER>/Documents/terraform-install
22+
COPY Package to "terraform-install" folder
23+
24+
# Unzip
25+
unzip <PACKAGE-NAME>
26+
unzip terraform_0.15.4_darwin_amd64.zip
27+
28+
# Copy terraform binary to /usr/local/bin
29+
echo $PATH
30+
mv terraform /usr/local/bin
31+
32+
# Verify Version
33+
terraform version
34+
35+
# To Uninstall Terraform (NOT REQUIRED)
36+
rm -rf /usr/local/bin/terraform
37+
```
38+
39+
## Step-03: MACOS: IDE for Terraform - VS Code Editor
40+
- [Microsoft Visual Studio Code Editor](https://code.visualstudio.com/download)
41+
- [Hashicorp Terraform Plugin for VS Code](https://marketplace.visualstudio.com/items?itemName=HashiCorp.terraform)
42+
- Configure [Course Github Repository](https://github.com/stacksimplify/hashicorp-certified-terraform-associate-on-azure) using VS Code Editor

48+
```t
49+
# Install XCode
50+
brew update
51+
xcode-select --install
52+
Observation: Verify images for reference in "image-reference" folder
53+
54+
# Sample Error (Without Xcode if we try az cli install it will through this error)
55+
Error: python@3.8: the bottle needs the Apple Command Line Tools to be installed.
56+
You can install them, if desired, with:
57+
xcode-select --install
58+
59+
60+
# AZ CLI Current Version (if installed)

82+
83+
84+
## Step-05: Terraform - Authenticating using the Azure CLI
85+
- [Azure Provider: Authenticating using the Azure CLI](https://registry.terraform.io/providers/hashicorp/azurerm/latest/docs/guides/azure_cli)
86+
```t
87+
# Azure CLI Login
88+
az login
89+
90+
# List Subscriptions
91+
az account list
92+
93+
# Set Specific Subscription (if we have multiple subscriptions)
94+
az account set --subscription="SUBSCRIPTION_ID"
95+
```
96+
97+
## Step-06: Install Git Client
98+
- [Download Git Client](https://git-scm.com/downloads)
99+
- This is required when we are working with `Terraform Modules`
100+
101+
## Step-07: WindowsOS: Terraform & Azure CLI Install
102+
### Step-07-01: Install Git Client
103+
- [Download Git Client](https://git-scm.com/downloads)
104+

108+
- `Step-05:Terraform - Authenticating using the Azure CLI` is going to be same for WindowsOS too.
109+
```t
110+
# Azure CLI Login
111+
az login
112+
113+
# List Subscriptions
114+
az account list
115+
116+
# Set Specific Subscription (if we have multiple subscriptions)
117+
az account set --subscription="SUBSCRIPTION_ID"
118+
```
119+
120+

122+
- [Install CLI](https://learn.hashicorp.com/tutorials/terraform/install-cli)
123+
- Unzip the package
124+
- Create new folder `terraform-bins`
125+
- Copy the `terraform.exe` to a `terraformbins`
126+
- Set PATH in windows
127+
128+
### Step-07-04: Configure Course Git Repo
129+
- [Course Git Repo](https://github.com/stacksimplify/hashicorp-certified-terraform-associate-on-azure)
130+
- Shorten Course folder name to smaller one. Put it in C:\ Drive root path
131+
132+
### Step-07-05: Install Visual Studio Code and Terraform Plugin
133+

136+
137+
### Step-07-06: WindowsOS: Long Path Issues for Terraform CLI
138+
- [Windows10 Long File Name or Path](https://github.com/hashicorp/terraform/issues/21173)
139+
- [Microsoft fix](https://answers.microsoft.com/en-us/windows/forum/all/windows-10-commands-with-long-path-name-are-not/13f0f7c7-d55c-4c6c-b19d-9dfec099dd45)
140+
- Our fix is to shorten our git repo names to see if that helps
141+

5+
6+
## Step-01: Introduction
7+
- Understand basic Terraform Commands
8+
1. terraform init
9+
2. terraform validate
10+
3. terraform plan
11+
4. terraform apply
12+
5. terraform destroy

17+
18+
## Step-02: Review terraform manifests
19+
- **Pre-Conditions-1:** Get Azure Regions and decide the region where you want to create resources
20+
```t
21+
# Get Azure Regions
22+
az account list-locations -o table
23+
```
24+
- **Pre-Conditions-2:** If not done earlier, complete `az login` via Azure CLI. We are going to use Azure CLI Authentication for Terraform when we use Terraform Commands.
25+
```t
26+
# Azure CLI Login
27+
az login
28+
29+
# List Subscriptions
30+
az account list
31+
32+
# Set Specific Subscription (if we have multiple subscriptions)
33+
az account set --subscription="SUBSCRIPTION_ID"
34+
```
35+
- [Azure Regions](https://docs.microsoft.com/en-us/azure/virtual-machines/regions)
36+
- [Azure Regions Detailed](https://docs.microsoft.com/en-us/azure/best-practices-availability-paired-regions#what-are-paired-regions)
37+
```t
38+
# Terraform Settings Block
39+
terraform {
40+
required_version = ">= 1.0.0"
41+
required_providers {
42+
azurerm = {
43+
source = "hashicorp/azurerm"
44+
version = ">= 2.0" # Optional but recommended in production
45+
}
46+
}
47+
}
48+
# Configure the Microsoft Azure Provider
49+
provider "azurerm" {
50+
features {}
51+
}
52+
# Create Resource Group
53+
resource "azurerm_resource_group" "my_demo_rg1" {
54+
location = "eastus"
55+
name = "my-demo-rg1"
56+
}
57+
```
58+
59+
## Step-03: Terraform Core Commands
60+
```t
61+
# Terraform Initialize
62+
terraform init
63+
64+
# Terraform Validate
65+
terraform validate
66+
67+
# Terraform Plan to Verify what it is going to create / update / destroy
68+
terraform plan
69+
70+
# Terraform Apply to Create Resources
71+
terraform apply
72+
```
73+
74+
## Step-04: Verify Azure Resource Group in Azure Management Console
75+
- Go to Azure Management Console -> Resource Groups
76+
- Verify newly created Resource Group
77+
- Review `terraform.tfstate` file
78+
79+
## Step-05: Destroy Infrastructure
80+
```t
81+
# Destroy Azure Resource Group
82+
terraform destroy
83+
Observation:
84+
1. Verify if the resource group got deleted in Azure Management Console
85+
2. Verify terraform.tfstate file and resource group info should be removed
86+
3. Verify terraform.tfstate.backup, it should have the resource group info here stored as backup.
87+
88+
# Delete Terraform files
89+
rm -rf .terraform*
90+
rm -rf terraform.tfstate*
91+
```
92+
93+
## Step-08: Conclusion
94+
- Re-iterate what we have learned in this section
95+
- Learned about Important Terraform Commands
96+
1. terraform init
97+
2. terraform validate
98+
3. terraform plan
99+
4. terraform apply
100+
5. terraform destroy

title: Terraform Configuration Language Syntax

description: Learn Terraform Configuration Language Syntax like Blocks, Arguments, Comments etc
4+
---
5+
6+
## Step-01: Introduction
7+
- Understand Terraform Language Basics
8+
1. Understand Blocks
9+
2. Understand Arguments, Attributes & Meta-Arguments
10+
3. Understand Identifiers
11+
4. Understand Comments
12+
13+
14+
## Step-02: Terraform Configuration Language Syntax
15+
- Understand Blocks
16+
- Understand Arguments
17+
- Understand Identifiers
18+
- Understand Comments
19+
- [Terraform Configuration](https://www.terraform.io/docs/configuration/index.html)
20+
- [Terraform Configuration Syntax](https://www.terraform.io/docs/configuration/syntax.html)
21+
```t
22+
# Template
23+
<BLOCK TYPE> "<BLOCK LABEL>" "<BLOCK LABEL>" {
24+
# Block body
25+
<IDENTIFIER> = <EXPRESSION> # Argument
26+
}
27+
28+
# Azure Example
29+
# Create a resource group
30+
resource "azurerm_resource_group" "myrg" { # Resource BLOCK
31+
name = "myrg-1" # Argument
32+
location = "East US" # Argument
33+
}
34+
# Create Virtual Network
35+
resource "azurerm_virtual_network" "myvnet" { # Resource BLOCK
36+
name = "myvnet-1" # Argument
37+
address_space = ["10.0.0.0/16"]
38+
location = azurerm_resource_group.myrg.location # Argument with value as expression
39+
resource_group_name = azurerm_resource_group.myrg.name # Argument with value as expression
40+
}
41+
```
42+
43+
## Step-03: Understand about Arguments, Attributes and Meta-Arguments.
44+
- Arguments can be `required` or `optional`
45+
- Attribues format looks like `resource_type.resource_name.attribute_name`
46+
- Meta-Arguments change a resource type's behavior (Example: count, for_each)

- [Resource: Meta-Arguments](https://www.terraform.io/docs/language/meta-arguments/depends_on.html)
52+
53+
## Step-04: Understand about Terraform Top-Level Blocks
54+
- Discuss about Terraform Top-Level blocks
55+
1. Terraform Settings Block
56+
2. Provider Block
57+
3. Resource Block
58+
4. Input Variables Block
59+
5. Output Values Block
60+
6. Local Values Block
61+
7. Data Sources Block
62+
8. Modules Block
