You should not have to hand over a 30 page document to a new developer to teach them how to set up your application so they can run it locally. It will work properly in all environments and on all machines capable of running Docker. Cross Environment ConsistencyДocker allows you to encapsulate your application in such a way that you can easily move it between environments. If youвЂ™re constantly looking for ways to improve your productivity and make the overall software development experience better, youвЂ™ll appreciate the following 5 key benefits Docker offers: 1. What if you wanted to share your project on GitHub and other developers only had to run a single command to get everything running in minutes?ДЄll of this and much more is possible thanks to Docker. What if you could spin up your Rails, PostgreSQL, Redis, and Sidekiq stack in about 5 seconds? What if as a consultant or freelancer with 10 Rails projects, you had everything you needed isolated for each project without needing to waste precious SSD disk space?

What if you could develop your Rails application in isolation on your work station without using RVM or chruby, and changing Ruby versions were super easy? Docker is very lightweight-it typically takes a few milliseconds for a container to start, and running a container doesnвЂ™t use much disk space at all. It also takes many seconds to boot-up a virtual machine, and each VM can potentially be gigabytes in size.Дocker containers share your hostвЂ™s kernel, and isolation is done using cgroups and other linux kernel libraries. They allow you to isolate services, but there are a few major differences that make virtual machines much less efficient.ДЇor starters, you need to have an entire guest operating system for each application you want to isolate. You may have used Vagrant, VirtualBox, or VMWare to run a virtual machine. What Makes Docker Different from a Virtual Machine

The Docker image contains the code, runtime, system libraries and anything else you would install on a server to make it run if you werenвЂ™t using Docker. This unit is typically labeled as a Docker image.Д®verything the application needs to run is included. TomFern / dockerizing-ruby What is Docker?Дocker allows you to package up an application or service with all of its dependencies into a standardized unit.
