It would be easier to understand what is Docker if we have a basic understanding of virtualization and virtual machines (also known as 'VMs'). What we know today as 'Cloud Computing' is nothing but a bunch of virtual machines running on a server. Each of these Vms (virtual machines) have their own CPU(s), memory & hard disk allocated from the host server and may be running different operating systems. However, in Docker, there are no Virtual Machines. Instead, we refer to what is known as a 'container'. Unlike virtual machines, which need a full Operating System to start up and run, Docker containers share a common kernel and only need those components that are not commonly available in the Operating Systems. Docker containers help developers to create, deploy and run different applications. All they need to do is to set up a container with the right environment for the application to run properly which may include supporting applications, files, libraries etc. Bundle all this in a container and you will not have to worry abot setting it up again - in any other location or environment. Docker runs on Linux as well as Windows.
Docker is open source. There are a number of Docker editions. While the Community Edition is free, the Enterprise Edition (EE) is not free. Understandably, the Enterprise Edition comes with support and certification as well. A number of companies are engaged in comparing virtual machines (vms) and docker containers in order to take a decision to move to Docker containers as against virtual machines. Docker, being open source allows you to add your own features if the standard out of the box functionalities do not fully meet your virtualizaton needs. Another feature that needs to be considered is security. Are Docker containers really secure? Are Docker containers more secure than virtual machines? This article by Daniel J Walsh that will answer this question about container security.
Docker containers have become popular among software developers because they are lightweight, portable, flexible and can be deployed in any environment. A good example would be one where a developer develops an application and sets it up in a Docker container. The Docker container would contain supporting applicaions, files, libraries that are needed to run the application. The set up is done just once and thereafter the container can be run anywere. A Docker container image is a snapshot of a container. Docker images are created using the build command and when run, they will reproduce the container. Docker container images almost function like executable files. Docker containers are based on "LXC" or just "Linux Containers". Docker made a number of changes to the original LXC technology and eventually made it more portable, flexible and easier to use. To be more specific, with Docker containers, it is a lot easier to develop, deploy, replicate, move and back up applications. Thanks to Docker, containers have almost become more popular than virtual machines.
Docker comes with containers whereas VMs are virtual machines which function as individual computers, each with its own operating system and hardware environment like CPU, RAM, HDD etc. VMs are based on virtualiation, which is made possible by Hypervisor technology. To keep it very simple, lets just say that Hypervisor is a software for managing virtual machines in a virtual (cloud) environment. A virtual machine has access to all physical devices on the host server. There are a number of products that allow you to create and deploy virtual machines. Some of them are Oracle Virtualbox, VMWare player, Hyper-v, Citrix Xenclient, Parallels Desktop etc.
On the other hand, Docker works on the idea of containers. These containers do not need a separate instance of the operating system. They just need the stuff that is not present in the common operating system kernel. Some applications are designed to run from multiple containes. A Docker compose file is used to configure the multi-container application's services. Then, you can start up your multi-container application with one single command, by starting the services from the compose file.
Play with Docker or just PWD is the name of a website called play-with-docker.com. Created by two Docker captains, Marcos Nils and Jonathan Leibiusky, Play with Docker is a 'fun and interactive' Docker training site or 'playground' which has a number of free labs where you can run Docker commands and get a feel of how exactly Docker works. Users can create and manage their own PWD hosts to run their own applications and training workshops. PWD also allows you to upload your own Docker files directly into your PWD windows with simple drag and drop functionality. PWD comes with a number of other interesting features which you can check out on their website.
