It allows you to start, stop, restart and inspect containers. Docker Clientĭocker Client is how we interact with and view our images & containers. It also includes VirtualBox under the hood for Windows and Mac installations, Docker only runs natively on Linux and Windows Server. The toolbox includes: Docker Client, Docker Machine, Docker Compose and Docker Kitematic. The Docker Toolboxĭocker Toolbox provides image and container tools which allow you to write images and build containers. Shipping softwareĪll of the above contribute to making it easier and faster to ship code, using containers increases the reliability of your application. Environment consistencyĪnother issue many of us have faced in the working world is thinking we've got parallel tracks for the development/staging/production environments and then being surprised by the fact that they were not!ĭocker can alleviate this issue because it packages environmental dependencies within the container, meaning you can start on the same base OS and then just swap out the container you're using in all environments.

With Docker you can only upgrade the applications that are ready.

This means that you could have two apps both running Node.js, one of them is ready to update to the latest version but the other will break if you update Node. With Docker this isn't a problem because all containers are isolated from one another and therefore won't impact each other. Many developers have had an experience of wanting to upgrade to the latest version of a language or framework but have been told to wait a while, because of the impact it could have on other running applications.

Docker can eliminate a lot of this pain, because all you do is install docker and run the container! You could literally just follow a step-by-step guide to get the app running on a new machine in minutes. Getting new developers on projects is usually a long and arduous process and this is because of the time it takes to set-up the development environment on their machine, getting all of the frameworks, source files etc that is required for an application and then sorting out permissions and installation issues. There are a variety of benefits, some of which are: It's a lot faster to skip the whole turning on the pc! The benefits of Docker It's kind of like the difference between starting an application vs starting your computer and then the application. Containers vs Virtual Machines, courtesy of Docker Inc. With containers, all running containers share a common kernal all sitting on top of the Docker Engine.įigure 1. The major difference between Virtual Machines (VMs) and containers is that VMs are bigger, because they package the OS with each VM and each VM sits on top of a hypervisor (cite).

What's the difference between containers and Virtual Machines?

The container contains the actual application as opposed to an image, which is the instructions on how to run the application.

ContainersĪ container is an isolated and secure container created from an image that can be run. Images are used to build Docker containers. It is a read-only template, comprised of layered filesystems that allow sharing of common files. It contains instructions on how to run your application, including all the dependencies and set-up work. What are they? ImagesĪn image is the blueprint to running your application. Docker containerises your code, making it easier to transport and more reliable to use.ĭocker relies on images and containers, they are your fundamental building blocks in Docker. Docker is a tool that simplifies building, shipping and running applications.
