Terraform Infrastructure Practice by Dibakar Patro

This repository contains multiple practice projects and Terraform configuration files to automate and manage infrastructure on AWS. Each folder represents a different Terraform topic, exercise, or task, progressing from basic to more advanced concepts like EC2 instances, S3 buckets, modules, provisioners, and clusters.

Repository Structure

1. day01_create_ec2&s3

• Basic Terraform script to create an EC2 instance and S3 bucket.
• Demonstrates the foundational skills of launching resources using Terraform.

2. day02_create_ec2_by_variable

• Terraform configuration to create an EC2 instance using variables.
• Shows how to make infrastructure more dynamic by defining and using variables.

3. day03_create_custom_NW

• Creates a custom VPC with subnets, route tables, and a gateway.
• Learn how to configure your own network in AWS using Terraform.

4. day04_remote_statefile_configure

• Configures a remote backend for storing Terraform state files.
• Important for collaboration and tracking infrastructure state.

5. day04_statefile_creates3

• Creates an S3 bucket for storing the Terraform state file.
• Shows the process of keeping state files secure and centralized.

6. day05_life_cycle_rule

• Introduces the lifecycle rules in Terraform to manage resources.
• Learn how to control resource creation, updates, and destruction.

7. day06_dependency_block

• Demonstrates how to set dependencies between resources in Terraform.
• Ensures that resources are created in the correct order.

8. day07_multiproviders

• Uses multiple providers within a single Terraform configuration.
• Learn to manage infrastructure in different regions or clouds.

9. day08_module_practice

• Implements reusable Terraform modules.
• Shows how to organize and reuse code efficiently.

10. day09_ec2_new_keypair

• Creates an EC2 instance with a new SSH key pair for secure access.

11. day09_ec2_userdata

• Configures EC2 instances using user data scripts.
• Automates software installation and configuration during instance launch.

12. day10_provisioners

• Practice using provisioners to run scripts on EC2 instances.
• Helps in bootstrapping instances with required configurations.

13. day11_count

• Demonstrates the count feature to create multiple instances of a resource.

14. day11_locals

• Use of local values in Terraform for cleaner, more maintainable code.

15. day12_foreach

• Demonstrates the for_each meta-argument to loop through resources dynamically.

16. hit_apply_to_the_target_one

• Targets a specific resource in Terraform to apply changes to that resource only.

17. null_resource

• Experimenting with null resources and local provisioners for custom workflows.

18. something_new

• Cluster creation: Set up a new cluster, demonstrating advanced Terraform usage.

19. Update terraform.tf

• Updates and changes to the base terraform.tf files.

How to Use

1. Clone the repository:

   git clone https://github.com/dibakarpatro/Terraform-cloud-automation.git

2. Navigate to the directory of the day/topic you want to practice:

   cd day01_create_ec2&s3

3. Initialize Terraform:

   terraform init

4. Run a Terraform plan to see the infrastructure changes:

   terraform plan

5. Apply the Terraform configuration to deploy infrastructure:

   terraform apply

6. Destroy resources once you're done:

   terraform destroy

Notes

• Make sure you have AWS credentials configured for Terraform to interact with your AWS account.
• Each day or folder contains its own separate configuration file and infrastructure setup.
• Some folders, like something_new, contain more complex examples such as cluster setups.

Requirements

• Terraform
• AWS account with proper IAM permissions.
