Have you ever wanted to automate Docker container deployment on an EC2 instance. That was exactly what I wanted to do last week and instead of doing it the old-fashioned way with SSH and manual scripts, I decided to automate it using Ansible and run it through GitHub Actions (CI/CD). The result? A super clean…
If you’ve been managing your Terraform state in AWS S3, you’ve probably been using DynamoDB to enable state locking. Well, here’s some great news: Terraform 1.10 lets you ditch DynamoDB and handle state locking directly in S3! No extra tables, no extra costs, and no more unnecessary complexity. So, how does it work? Let me…
Imagine a scenario where you might prefer to provision the resources manually in Cloud because it’s quick and easy. Maybe you needed a Cloud resource such as security group in a hurry, or someone on the team just created it without thinking about Terraform. Fast forward a few weeks, and now you’ve ended with a…
I have sometimes seen some people feel confused in choosing between count and for_each in Terraform. Both constructs help to dynamically create multiple resources, yet their use cases and behavior differ significantly. Let me break it down in simple terms and demonstrate their differences with an example: provisioning AWS Security Groups. Note: Since creating Security…
In modern IT, automation and efficiency are crucial. Terraform and Ansible are leading Infrastructure as Code (IaC) tools, each with unique strengths. Terraform excels at provisioning cloud infrastructure across multiple providers using a declarative language, while Ansible focuses on configuration management and application deployment through agentless automation. Terraform Overview Terraform, developed by HashiCorp, allows…
In this article, I will guide you with the steps on how to provision an instance (VM) in AWS Cloud by using Terraform code and a CICD pipeline that is GitHub Action. But before proceeding further, let me give you a brief overview of Terraform and GitHub Action. Terraform Terraform is an open-source Infrastructure…
Variables or Vars are used to store the data which is further used by ansible playbook. These variables can either take input from user or it can also be stored in YAML or INI file as well like main.yml or inventory. Variables stored in either playbook or in separate YAML or INI format file can…
Red Hat Ansible Automation Platform (AAP) or Ansible Tower has become de facto Automation Tool for deploying the Automation projects to automate the System Administration tasks such as configuration management, application deployment, provisioning, orchestration, and continuous delivery. Although AAP and Ansible Tower are designed to run on large scale Infrastructure environment but sometime running complex…
