DevOps and Automation

Here is a step-by-step tutorial on setting up a Jenkins CI/CD pipeline to automate the creation, testing, and distribution of your apps. Also, we'll connect it with GitLab so that code pushes will start automatic builds. We will also show how using VS Code and this CI/CD pipeline enables more rapid and dependable software delivery. Prerequisites: Jenkins  installed and set up on your server or local machine. GitLab  repository with your application's source code. A sample  application  (e.g., a simple web app) that you want to deploy using this CI/CD pipeline. VS Code  installed on your development machine.

1. AUTOMATING VIRTUAL MACHINE DEPLOYMENT - Create a Terraform Script to work in GCP/Azure such that it creates a specified number of VM(s)  In this scenario,  You can specify the instance types, OS images, networking configurations, and any additional settings required. BEST PRACTISE  TO FOLLOW FOR THIS SCENARIO Use Version Control: Store your Terraform code in a version control system like Git. This allows you to track changes, collaborate with others, and roll back to previous configurations if needed. Organize Your Code: Structure your Terraform code into modules, each responsible for specific resources or components. This promotes code reusability and makes it easier to manage complex infrastructures. Keep Secrets Secure: Avoid hardcoding sensitive information like passwords or API keys directly in your Terraform code. Instead, use environment variables, external data sources, or cloud provider-specific secret management tools to store and retrieve secrets securel...
