How Terraform Works?

1. Write configuration
2. Initialize
3. Plan
4. Apply
5. Manage State
6. Destroy

What are the top 5 terraform commands
Top 5 Terraform commands are:

1. init – initializes the working directory that containing Terraform configuration file and download the necessary provider plugins
2. plan – Generates an execution plan. Show what actions Terraform will take to create, update or delete resources. Useful for understanding changes before applying them.
3. apply – apply the changes to reach desire state of the configuration. Creates, updates or deletes resources based on execution plan.
4. destroy – deletes all the resources defined in the configuration. useful for cleaning up environments when they are no longer needed
5. fmt – format the configuration files to follow the canonical format and style. Ensure consistency and readability in configuration files.

Write a Sample Terraform code for your fav providers.

provider “aws” {
 access_key = “var.access_key”
 secret_key = “var.secret_key”
 region = var.region
}

resource “ami_instance” “webserver” {
 ami = var.ami
 instance_type = var.instance_type
}

How Terraform Works?
Terraform’s workflow involves writing declarative configuration files, initializing the environment, planning changes, applying changes, and maintaining state

What are the top 5 terraform commands

terraform init
terraform plan
terraform apply
terraform destroy
terraform state

Write a Sample Terraform code for your fav providers.

For VMware provider

terraform {

 required_providers {

   vsphere = {

     source = "hashicorp/vsphere"

     version = "2.8.1"

   }

 }

}




provider "vsphere" {

 # Configuration options

}

• It is a very useful and simple tool which can be used to build any infrastructure

How Terraform Works?

• Terraform uses the APIs of supported cloud platforms to connect with them and interract (create new or change existing objects)

What are the top 5 terraform commands

• plan
• apply
• destroy
• show
• init

Write a Sample Terraform code for your fav providers.

• sample code

# Configure the Azure provider
terraform { 
required_providers {   
azurerm = {     
source = “hashicorp/azurerm”     
version = “~> 3.0.2”   
} 
}
required_version = “>= 1.1.0”
}

  username            = "changemeusername"
  password            = "changeme_password"
  skip_final_snapshot = true
}

How Terraform Works:
Terraform work with below steps
Write Configuration
Initialize
Plan: 
Apply
Destroy

Top 5 Terraform Commands:

terraform init
terraform plan
terraform apply
terraform show
terraform destroy

How Terraform Works?
Is a opencode tool using a simple syntax, Terraform provisions infrastructure across multiple data centers (providers) in the cloud and on-premises. Additionally, it securely and efficiently re-provisions infrastructure in response to configuration changes.

What are the top 5 terraform commands
-Init
-Destroy
-Validate
-Plan
-Apply

Write a Sample Terraform code for your fav providers.
 
terraform {
 required_providers {
   azurerm = {
     source = “hashicorp/azurerm”
     version = “3.107.0”
   }
 }
}
 
provider “azurerm” {
 # Configuration options
}

 [
  {
    "cloudName": "AzureCloud",
    "id": "IDDETENTANT",
    "isDefault": true,
    "name": "CLIENT Subscription",
    "state": "Enabled",
    "tenantId": "TENTANTID",
    "user": {
      "name": "user@example.com",
      "type": "user"
    }
  }
]

1. Terraform it is a “GO” language which allow you to Create/Update/Destroy objects.
2. Run code located in current directory, connect by the provider to the infrastructure and then C/U/D something and give you output.
3. plan/apply/init/get/validate

resource “aws_instance” “web” {
ami = “linux8.8”
instance_type = “something”
key_name = “Kyndryl_training”

tags = {
Name = “Hi_all”

2. Terraform creates and manages resources on cloud platforms and other services through their application programming interfaces (APIs).

3.init, validate, plan, apply, destroy

4. terraform {
 required_providers {
  github = {
   source = “integrations/github”
   version = “~> 6.0”
  }
 }
}

# Configure the GitHub Provider
provider “github” {}

Terraform manages resources with the help of providers or APIs on end points.

Commands – Init, plan, destroy, validate, and show.

provider “Azure” {
region = “us-east”
}

Terraform work as a code which communicate to an infrastructure

This is being used by DevOps team to automate various task in the infrastructure

The top Terraform command
Init
validate
plan
apply
destroy

2) How Terraform Works?
It reads a terraform code, and send to different providers to create, update or delete resources using API.

3) What are the top 5 terraform commands
init, plan, apply, destroy, validate

4) Write a Sample Terraform code for your fav providers.
resource “aws_instance” “web” {
 ami      = ami.289416498369649
 instance_type = “t2.micro”

 tags = {
  Name = “MyNewInstance”
 }
}
