Introduction to Terraform - Terraform is an open-source infrastructure as code software tool created by HashiCorp. - It allows users to define and provision data center infrastructure using a declarative configuration language. ### 2. Installation - **Download**: Go to the [Terraform downloads page](https://www.terraform.io/downloads.html) to download the zip file for your operating system. - **Installation**: Extract the zip file and move the `terraform` executable to a directory included in your system's `PATH`. - **Verify Installation**: Run the following command to ensure Terraform is installed correctly: ```bash terraform -v ``` ### 3. Basic Concepts - **Providers**: Plugins that Terraform uses to interact with APIs. Examples include AWS, Azure, Google Cloud, etc. - **Resources**: The components that Terraform manages, such as virtual machines, storage accounts, etc. ### 4. Providers - To use a provider, you need to declare it in your Terraform configuration. Example: ```hcl provider "aws" { region = "us-west-2" } ``` ### 5. Resources - Resources define the components of your infrastructure. Here’s an example of an AWS EC2 instance: ```hcl resource "aws_instance" "example" { ami = "ami-0c55b159cbfafe1f0" instance_type = "t2.micro" } ``` ### 6. Variables - Variables allow you to customize your configurations. Example of defining a variable: ```hcl variable "instance_type" { type = string default = "t2.micro" } ``` ### 7. State Management - Terraform maintains a state file to keep track of resources and their metadata. By default, the state file is named `terraform.tfstate`. - **Command** to view the current state: ```bash tf state list ``` ### 8. Modules - Modules are containers for multiple resources that are used together. You can define modules within your configuration file: ```hcl module "vpc" { source = "./modules/vpc" cidr_block = "10.0.0.0/16" } ``` ### 9. Output Values - Outputs allow you to extract information from your configurations. Example: ```hcl output "instance_ip" { value = aws_instance.example.public_ip } ``` ### 10. Intermediate Concepts - **Terraform Workspaces**: Allow managing different environments (e.g., dev, prod) within the same configuration. - **Terraform Cloud**: A service for versioning, collaboration, and execution of Terraform scripts. --- ### Conclusion - These notes provide a foundation on which you can build and learn more advanced topics in Terraform.

### 1. Introduction to Terraform
- Terraform is an open-source infrastructure as code software tool created by HashiCorp.
- It allows users to define and provision data center infrastructure using a declarative configuration language.
### 2. Installation
- **Download**: Go to the [Terraform downloads page](https://www.terraform.io/downloads.html) to download the zip file for your operating system.
- **Installation**: Extract the zip file and move the `terraform` executable to a directory included in your system's `PATH`.
- **Verify Installation**: Run the following command to ensure Terraform is installed correctly:
```bash
terraform -v
```
### 3. Basic Concepts
- **Providers**: Plugins that Terraform uses to interact with APIs. Examples include AWS, Azure, Google Cloud, etc.
- **Resources**: The components that Terraform manages, such as virtual machines, storage accounts, etc.
### 4. Providers
- To use a provider, you need to declare it in your Terraform configuration. Example:
```hcl
provider "aws" {
region = "us-west-2"
}
```
### 5. Resources
- Resources define the components of your infrastructure. Here’s an example of an AWS EC2 instance:
```hcl
resource "aws_instance" "example" {
ami = "ami-0c55b159cbfafe1f0"
instance_type = "t2.micro"
}
```
### 6. Variables
- Variables allow you to customize your configurations. Example of defining a variable:
```hcl
variable "instance_type" {
type = string
default = "t2.micro"
}
```
### 7. State Management
- Terraform maintains a state file to keep track of resources and their metadata. By default, the state file is named `terraform.tfstate`.
- **Command** to view the current state:
```bash
tf state list
```
### 8. Modules
- Modules are containers for multiple resources that are used together. You can define modules within your configuration file:
```hcl
module "vpc" {
source = "./modules/vpc"
cidr_block = "10.0.0.0/16"
}
```
### 9. Output Values
- Outputs allow you to extract information from your configurations. Example:
```hcl
output "instance_ip" {
value = aws_instance.example.public_ip
}
```
### 10. Intermediate Concepts
- **Terraform Workspaces**: Allow managing different environments (e.g., dev, prod) within the same configuration.
- **Terraform Cloud**: A service for versioning, collaboration, and execution of Terraform scripts.
