What is Azure DevOps?

Free Course Azure DevOps is a set of tools from Microsoft that helps software teams manage their projects, write and test code, and deploy applications. It brings together several key services to streamline the entire development process. Here's an example to show how it works: Project: Building a New Website Planning with Azure Boards: Your team starts by using Azure Boards to organize and track tasks. They create a list of features, bugs, and other tasks, and use a Kanban board to see what's in progress, what's done, and what's coming up next. This helps everyone stay on the same page and prioritize work effectively. Code Management with Azure Repos: As developers write code for the website, they save it to a Git repository in Azure Repos. This version control system allows multiple developers to work together, keeping track of changes and making sure nothing gets lost. Building and Deploying with Azure Pipelines: Whenever new code is pushed to the repository, Azure P...

How to Install Minikube

 Minikube is a great tool for running Kubernetes locally on your machine. Let’s walk through the setup step by step. What You Need First Hypervisor : Minikube needs a virtual machine (VM) to run Kubernetes. You can use VirtualBox, VMware, Hyper-V (for Windows), or Docker. Make sure you’ve got one of these installed. kubectl : This is the command-line tool for Kubernetes. You can get it from the Kubernetes website . Installation Steps Get Minikube On Windows : Download the Minikube executable from the Minikube GitHub releases page . Look for minikube-windows-amd64.exe . Rename the file to minikube.exe and put it in a folder that's in your system’s PATH , like C:\Program Files\ . On macOS : The easiest way is to use Homebrew. Open a terminal and run: brew install minikube On Linux : Download the Minikube binary: curl -LO https://storage.googleapis.com/minikube/releases/latest/minikube-linux-amd64 Make it executable: chmod +x minikube-linux-amd64 Move it to a directory in your PATH...

Scenario-Based interview DevOps - 2

7. Handling Configuration Drift Scenario: You’ve noticed that the configurations of your production servers have drifted from the configuration defined in your Infrastructure as Code (IaC) scripts. How would you address this issue? Answer: I would: Identify Drift : Use configuration management tools (e.g., Terraform, Ansible) to detect and compare the current configurations against the desired state. Reconcile Drift : Apply the IaC scripts or configuration management tool to bring the servers back in line with the defined configurations. Investigate Cause : Investigate why the drift occurred (e.g., manual changes, untracked modifications) and address the root cause to prevent future drifts. Implement Policies : Enforce policies or controls that prevent unauthorized changes to configurations, such as using version control and restricting direct access to servers. Automate : Automate the reconciliation process to regularly check and correct configuration drift. 8. Managing Dependency C...
