How does Docker 🐬work?


🔢. Docker Client: This is the interface where users interact with Docker using commands like:
• Docker build: Creates a Docker image based on the configurations defined in a Dockerfile.
• Docker push: Pushes the created image to a remote Docker registry for storage and sharing.
• Docker pull: Pulls an image from the Docker registry to the local environment.
• Docker run: Runs a container from an image on the Docker host.

🔢. Docker Host:
• Contains the Docker Daemon (or Docker Engine), which manages Docker objects like images, containers, networks, and volumes.
• It communicates with the Docker client to execute commands and manages the lifecycle of containers.

🔢. Containers and Images:
• Images: Immutable templates (like MySQL, Redis, NGINX) that contain the application code, runtime, libraries, and dependencies.
• Containers: Instances of images that run the application. Each container is an isolated environment where the application functions independently.

🔢. Docker Registry:
• Stores images and allows them to be shared between different environments.
• The Docker client can push and pull images to/from the registry, enabling distributed deployment of applications.

🔢. Workflow:
• Build: The Docker client builds an image and stores it locally or in the registry.
• Push: The built image can be pushed to a remote registry for easy access.
• Pull: Images from the registry can be pulled to the local environment as needed.
• Run: The Docker host runs containers from these images, creating isolated environments for each instance.

You're using Linux 🐧wrong!

Most people dive into Linux without truly understanding its file system hierarchy, leading to confusion and inefficiency.

Ever wondered why system files are scattered across /bin, /sbin, and /usr/bin? Or why logs are in /var/log instead of /log?

Here’s a breakdown of the Linux File System Hierarchy to clear up the confusion:

╰ / - Root directory (everything starts here)
╰ /bin - Essential binaries (ls, cp, mv)
╰ /boot - Boot loader files (kernel, GRUB)
╰ /dev - Device files (USB, HDD, tty)
╰ /etc - Configuration files
╰ /home - User home directories
╰ /lib - Essential system libraries
╰ /media - Auto-mounted media (USB, CD)
╰ /mnt - Temporary mount point
╰ /opt - Third-party software packages
╰ /proc - Virtual filesystem for processes
╰ /root - Root user’s home directory
╰ /run - Runtime process data
╰ /sbin - System binaries (fsck, reboot)
╰ /srv - Server-specific data
╰ /sys - Kernel system information
╰ /tmp - Temporary files (cleared on reboot)
╰ /usr - User applications and tools
╰ /usr/bin - Non-essential user binaries
╰ /usr/lib - Libraries for /usr/bin
╰ /usr/local - Locally installed software
╰ /usr/share - Shared data (icons, docs)
╰ /var - Variable data (logs, cache, mail)
╰ /var/log - System logs
╰ /var/spool - Queued jobs (print, mail)

Understanding this structure helps you -

🔠 Locate files efficiently
🔠 Troubleshoot system issues faster
🔠 Optimize performance & security

🚨 Azure DevOps Scenario Based Interview Questions 🚨


1. In your current project, could you describe the overall architecture of your CI/CD pipeline that you have designed for cloud applications in Azure DevOps?

2. Can you explain how you handled the integration of infrastructure-as-code (IaC) into your Azure DevOps pipeline? Did you use tools like Azure Resource Manager templates, Terraform, or others to manage resources, and how did it integrate with your CI/CD pipeline?

3. How do you manage different deployment strategies like Blue-Green Deployment or Canary Releases using Azure DevOps and Azure Cloud?

4. In your project, how do you handle the automation of your build pipelines using Azure DevOps?

5. Can you provide examples of scripts or commands you’ve used in the release pipeline for deploying to multiple environments

6. You mentioned using GitHub Actions for CI/CD automation. Can you provide a practical example of a custom script you created using GitHub Actions for automated testing or build tasks?

7. In Azure DevOps, you can use Azure CLI or PowerShell commands to automate tasks. Can you give an example of how you utilized these tools in your CI/CD pipeline to interact with Azure resources, such as creating or updating Azure VMs, storage accounts, or App Services?

8. In the context of your deployment pipeline, can you explain how you wrote a script that triggers the deployment process after successful completion of build steps? How do you implement a rollback strategy if something goes wrong during deployment?

9. Tell me the deployment process of a web application to Azure App Services using Azure DevOps pipelines. What steps and commands do you include in the pipeline, from building the artifact to testing and deploying to production?

10. How did you implement continuous monitoring during the deployment process? Could you give an example of how you track deployments in real-time, and how do you handle failed deployments?

11. In your current project, how did you handle the containerization of applications using Docker? Can you walk us through the process of creating a Dockerfile for a web application and how you integrated it into your Azure DevOps pipeline?

12. Once you containerized an application, how did you manage the deployment to Azure Kubernetes Service (AKS)? What steps did you follow to push your Docker images to Azure Container Registry (ACR), and how did you create and deploy Kubernetes manifests (YAML)?

13. Let’s say during a deployment, your build pipeline has passed successfully, but the deployment to a pre-prod environment fails. What steps would you take to debug the issue, and which logs or commands would you check first in Azure DevOps?

14. In your CI/CD pipeline, how do you handle automated testing? Can you explain how you integrated unit tests, into your pipeline using Azure DevOps?

🚨 Terraform Directory Structure – The Right Way! 🚨

Are you managing your Terraform projects correctly?
A well-structured Terraform directory ensures scalability, reusability, and efficient infrastructure management. Let’s dive into best practices!

1️⃣ Environments – Separate Configs for Dev, Staging & Prod
Managing multiple environments? Here’s how to structure them:
📂 Development/
📂 Staging/
📂 Production/

Each contains:
✅ main.tf – Defines cloud resources.
✅ variables.tf – Declares variables without values.
✅ outputs.tf – Stores Terraform outputs for dependencies.
✅ terraform.tfvars – Provides values for variables.

🔹 Why?
Isolates Dev, Staging, and Production setups.
Avoids accidental production changes.
Makes configurations modular & reusable.

2️⃣ Modules – Reusable Infrastructure Components
Instead of repeating code, Terraform Modules help reuse configurations.
📌 VPC Module – Handles Virtual Private Cloud creation.
📌 EC2 Module – Manages EC2 instances efficiently.

🔹 Why?
🚀 Eliminates duplicate code – Define once, use everywhere!
🔄 Ensures consistency across environments.
⚙️ Faster deployment – Just call the module!

3️⃣ Scripts – Automate Terraform Workflows
Automation is key in DevOps & IaC. These scripts help:
⚙️ init.sh – Initializes Terraform.
🛑 teardown.sh – Destroys infrastructure to save costs.
🔹 Why?
Saves time by automating Terraform operations.
Reduces manual errors while setting up infrastructure.

4️⃣ Core Terraform Files – The Brains of Your Infrastructure
These files are the foundation of your Terraform project:
✅ provider.tf – Specifies the cloud provider (AWS, Azure, GCP).
✅ backend.tf – Defines state management (e.g., AWS S3, Terraform Cloud).

🔹 Why?
Keeps Terraform state secure instead of local files.
Prevents conflicts in team environments.

🔍 Why This Directory Structure Matters?
✅ Organized, modular, and scalable Terraform projects.
✅ Prevents accidental changes in production.
✅ Reusable infrastructure with Terraform Modules.
✅ Automated setup & cleanup with scripts.
