DevOps(Day-85): Create a security group using terraform

 

  • Understanding Terraform Resources

  • Task 1: Create a security group

Yesterday, we saw how to create a Terraform script with Blocks and Resources. Today, we will dive deeper into Terraform resources.

A resource in Terraform represents a component of your infrastructure, such as a physical server, a virtual machine, a DNS record, or an S3 bucket. Resources have attributes that define their properties and behaviours, such as the size and location of a virtual machine or the domain name of a DNS record.

When you define a resource in Terraform, you specify the type of resource, a unique name for the resource, and the attributes that define the resource. Terraform uses the resource block to define resources in your Terraform configuration.

To allow traffic to the EC2 instance, you need to create a security group. Follow these steps:

In your main.tf file, add the following code to create a security group:

  • Create the terraform.tf file to define the providers

  • Create the provider.tf file to define the region.

  • Run terraform init to initialize the Terraform project.

  • Run terraform apply to create the security group.

  • Verify the console for the created security group by terraform.


Thanks for reading my article. Have a nice day.

DevOps(Day-97): Meta-Arguments in Terraform

  TABLE OF CONTENTS Write about meta-arguments and their use in Terraform. Task-01: Meta-Arguments HandsOn Count for-each When you define a resource block in Terraform, by default, this specifies one resource that will be created. To manage several of the same resources, you can use either count or for_each, which removes the need to write a separate block of code for each one. Using these options reduces overhead and makes your code neater. count is what is known as a ‘meta-argument’ defined by the Terraform language. Meta-arguments help achieve certain requirements within the resource block. Write about meta-arguments and their use in Terraform. Meta-arguments in Terraform refer to a set of special arguments that can be used to define how a particular resource or module behaves within a Terraform configuration. These arguments provide additional configuration options and enable fine-grained control over the behaviour of resources or modules. Meta-arguments are prefixed with the...

DevOps(Day-95): Auto Scaling with Terraform

Image
  TABLE OF CONTENTS Understanding Scaling Pre-requisites Task 1: Create an Auto Scaling Group Task 2: Test Scaling Yesterday, we learned how to AWS S3 Bucket with Terraform. Today, we will see how to scale our infrastructure with Terraform. Understanding Scaling Scaling is the process of adding or removing resources to match the changing demands of your application. As your application grows, you will need to add more resources to handle the increased load. And as the load decreases, you can remove the extra resources to save costs. Terraform makes it easy to scale your infrastructure by providing a declarative way to define your resources. You can define the number of resources you need and Terraform will automatically create or destroy the resources as needed. Pre-requisites Create a  terraform.tf  file declaring the providers to be installed in the system according to the resources required. Create a  provider.tf  file to declare the region. Create a  vp...

DevOps (Day-1) Introduction

Image
  TABLE OF CONTENTS Infrastructure Automation Why DevOps is Important? What is DevOps? As the name indicates:- Dev + Ops = Development + Operations. Development i) Backend Developers ii) Front-end Developers iii) QA Operations i) System admins ii) Network admins iii) Database admins The practice of operations and development engineers participating together in the entire service lifecycle through a pipeline from design through the development process to production support. This process is known as DevOps. This is a process of automating the whole infrastructure. Now here comes a query, what are we automating? We are automating the whole team's work from the code-building stage to code deployment. Scenario 1:- In a company, there is a project in which developers are writing the code and deploying it to the QA environment frequently for each sprint. This code is then tested by the testing team. Suppose there is a situation of mishap happens where the testing team used the older code ...
