Docker - The Complete Guide

🌟 Course Title: Docker - The Complete Guide

Course Description

Unlock the Power of Containerization with Docker!

Understanding Virtual Machines and Containers

• What is a Virtual Machine? 🛠️

  • A virtual machine (VM) is a computer file that acts as a complete computer system, running its own operating system.
  • It operates within a window, identical to any other application on your host OS.
  • Multiple VMs can coexist on the same physical server.

• Introducing Docker 🐳

  • Docker is an open-source platform revolutionizing the way applications are built, shipped, and run.
  • It isolates your application from the underlying infrastructure for faster deployment cycles.
  • Managing software becomes as easy as managing your applications, thanks to Docker.

The Docker Platform Explained

• Docker Engine: The Core

  • Docker Engine is a client-server application with a server daemon that handles the management of containers and a client which builds request.

• Docker Images: Building Blocks

  • Docker images are templates used for creating Docker containers, defined in Dockerfiles using instructions written in a simple text format.

Benefits of Docker 🚀

• Resource Efficiency: Docker is incredibly lightweight and performs better than traditional VMs due to process level isolation and shared kernel resources.

Docker Architecture and its Taxonomy

• The architecture of Docker is built around the Docker Engine, which includes a REST API for interacting with containers.

Create an Image Manually 🖌️

Step 1: Update the Code

1. Initiate a New Project: dotnet new MVC -n HelloWebApp
2. Add Dockerfile: Write a Dockerfile to define the environment for your application.

Azure Pipeline for Build and Publish Docker Image to Docker Hub 🤖

Azure Pipelines can be leveraged to build images for any repository containing a Dockerfile, supporting both Linux and Windows containers depending on the agent platform used.

Deploying to Web App �ploy

• Automate the deployment of your application to an Azure Web App for Linux Containers after every successful build, enabling seamless continuous integration and continuous deployment (CI/CD) workflows.

By the end of this comprehensive course, you'll have a robust understanding of Docker and containerization, enabling you to optimize your development pipeline with powerful CI/CD practices. Join us on this journey to master Docker and transform your approach to application deployment! 🛠️🚀🔧
