CBT Nuggets trainer Garth Schulte walks through everything you need to know about Docker, an open-source container-based technology that separates applications from their underlying operating system. Find out what Docker is and how it is used in DevOps with this MicroNugget video.
The concept of containers themselves aren't completely novel: Linux containers have been around for a while.
With those, a developer can package up an application and all its parts. That includes the stack it runs on and the dependencies associated with it.
The package becomes an isolated environment, containing everything the app needs to run. What that means is that the underlying system - the host - is abstracted from the application itself.
This is important because it circumvents dependency nightmares. If you develop an application on one machine and deploy it to a QA machine, if there are any differences in their dependencies, your application might not function in that environment, despite being a perfectly workable app.
Watch to understand exactly why so many huge companies and enterprises depend on containerized applications every day and Docker specifically. See how Docker provides continuous integration, continuous delivery, portability, scalability, density, and more.
