For Docker Online Training : +91-999 123 502 Agenda • Multi-Dimensional Evolution of Computing • What is Container? • Container Platforms • Why Containers? • Virtual Machines vs Containers • Containers and VMs together • Docker Basics • Docker for .NET Applications • Docker Engine Architecture

  3. For Docker Online Training : +91-999 123 502 Evolution of Computing

  4. For Docker Online Training : +91-999 123 502 What is Container? • A container is a software that contains an application code and all its dependencies. • Enables an application to run quickly in an isolated environment. • Provide smooth migration from one computing environment to another. • Share the same OS kernel • Works with all major Linux & Windows Server Source : www.docker.com

  5. For Docker Online Training : +91-999 123 502 Container Platforms Linux Containers (LXC) Docker (Docker Swarm) Kubernetes DC/OS RedHat OpenShift

  6. For Docker Online Training : +91-999 123 502 Why Containers? For Administrator For Developers •Quickly create ready-to-run packaged applications, low cost deployment •Automate testing, integration and packaging •Reduce/eliminate platform compatibility issues •Supports microservices development •Improve speed and frequency of releases, reliability of deployments •Makes app lifecycle efficient, consistent and repeatable-configure once, run many times •Eliminate environment inconsistencies between dev, test, and production •Provide Scalability on demand

  7. For Docker Online Training : +91-999 123 502 Virtual Machines vs. Containers Containers VMs Source : www.docker.com Source : www.docker.com

  8. For Docker Online Training : +91-999 123 502 Virtual Machine vs. Containers • Hardware-level virtualization • Fully isolated • Isolated OS • Having its own kernel • Slower in start-up • Many startup process • Upfront resource allocation • OS-level virtualization • Process-level isolation • Isolated processes/filesystems • Host machine kernel is used • Faster in start-up • Single Start-up process • No upfront resource allocation

  9. For Docker Online Training : +91-999 123 502 Containers and VMs together Source : www.docker.com

  10. For Docker Online Training : +91-999 123 502 Introduction to Docker • A light weight, open and secure platform for developing, shipping and running applications using container technology. • Provides Container solutions for developers, architects, DevOps, and IT People. • Run on most Linux distributions, Windows and Mac OS. • Supported by most of cloud providers like AWS, Azure, Google etc. • Provide Dev/Test, CI and DevOps platform for many use cases.

  11. For Docker Online Training : +91-999 123 502 Docker Benefits • Infrastructure Cost Savings • Standardization and Productivity • Isolation • Security • Makes app lifecycle efficient and consistent • Continuous Deployment and Testing • On Demand Scaling • Multi-Cloud Platforms Support

  12. For Docker Online Training : +91-999 123 502 Docker Desktop • An application for Mac and Windows to build production-ready container applications • Enables to build and test Linux & Windows based applications at local machine • Available in two editions: • Desktop Community • Desktop Enterprise

  13. For Docker Online Training : +91-999 123 502 Docker For Developers Windows Server Applications (.NET Core, Java, JS etc.) Linux

  14. For Docker Online Training : +91-999 123 502 Docker For .NET Applications .NET 3.5 & .NET 4.x Windows Server Core Legacy Applications Windows Nano Server .NET Core Linux

  15. For Docker Online Training : +91-999 123 502 Docker Basics • Docker File • Docker Image • Docker Container • Docker Registry

  16. For Docker Online Training : +91-999 123 502 Docker File • A simple text file that contains commands to build a docker image. • This file doesn’t have any extension. docker build Dockerfile

  17. For Docker Online Training : +91-999 123 502 Docker Image • A lightweight, standalone and executable package of software. • Includes everything which is needed to run an application like code, runtime, system tools, system libraries and settings. • An image is stack of multiple read only layers referencing another images. • Created by docker build command. • Stored in Docker registry (eg. Docker Hub). … .NET Core SDK Base Image (Ubuntu) Image = Layered File System

  18. For Docker Online Training : +91-999 123 502 Docker Container • Container is an running instance of a docker image • An isolated and secured shipping container • Run by docker run command docker run Operating System Software Application Code

  19. For Docker Online Training : +91-999 123 502 Docker Registry • A Service to host Docker images • Multiple options are available: • Docker Hub - (Free for public images and Paid for private images) • Docker Trusted Registry - (on-prem or on-cloud) docker push docker pull Docker Registry

  20. For Docker Online Training : +91-999 123 502 Docker Container Life Cycle Docker Registry Pull Push Stop Start Restart Run Build Commit Dockerfile Docker Local Instance

  21. For Docker Online Training : +91-999 123 502 Docker Engine • A runtime to build and run container based applications which can run anywhere consistently on any infrastructure. • Runs on various Linux (CentOS, Debian, Fedora, Oracle Linux, RHEL, SUSE, and Ubuntu) and Windows Server OS. • Provides built in orchestration, container networking, out of the box security, volume and plugins.
