This document provides an overview of working with Docker containers on Azure. It begins with an introduction to Docker and containers. It then covers installing Docker, basic Docker commands, building images with Dockerfiles, and deploying containers to Azure services. Specifically, it discusses using Azure Container Registry to store images, Azure Container Instances to deploy standalone containers, and Azure App Service to deploy containerized apps. Examples are provided for common Docker commands and building a sample Node.js app into a container.

- 3. What is Docker? Docker is a company that provides software (also called Docker) that allows you to build, run and manage software containers.
- 4. What is a container? Containers provide a standard way to package your application's code, configurations, and dependencies into a single object. Image source : https://aws.amazon.com/containers/
- 5. Install Docker for Windows • Download the installer from https://docker.com • Follow the install wizard to accept the license, authorize the installer, and proceed with the install. • Click Finish on the setup complete dialog to launch Docker. • Double click on Docker Desktop icon https://docs.docker.com/docker-for- windows/install/
- 6. Basic Terminologies of Docker Images - The file system and configuration of our application which are used to create containers. Containers - Running instances of Docker images — containers run the actual applications. A container includes an application and all of its dependencies. It shares the kernel with other containers, and runs as an isolated process in user space on the host OS. Docker daemon - The background service running on the host that manages building, running and distributing Docker containers.
- 7. Basic Terminologies of Docker Docker client - The command line tool that allows the user to interact with the Docker daemon. Docker Store - Store is a registry of Docker images. You can think of the registry as a directory of all available Docker images.
- 8. Docker commands • docker run – Runs a command in a new container. • docker start – Starts one or more stopped containers • docker stop – Stops one or more running containers • docker pull – Pulls an image or a repository from a registry
- 9. Docker commands • docker push – Pushes an image or a repository to a registry • docker exec – Runs a command in a run-time container • docker build – Builds an image from a Docker file • docker search – Searches the Docker Hub for images
- 10. Dockerfile A Dockerfile is a text document that contains all the commands a user could call on the command line to assemble an image. Using docker build users can create an automated build that executes several command-line instructions in succession. https://docs.docker.com/engine/reference/builder/
