(Update) We’ve released new training material on Docker, including the Cloud Academy’s Docker in Depth Learning Path. This learning path is designed to teach you all about Docker starting from the individual container and progressing to the continuous deployment of an application in AWS. The Learning Path comprises of video Courses, Hands-on Labs, and Quizzes to test your skills. Visit the Cloud Academy’s Training Library for all our latest content on Docker.
Docker has been acclaimed as a revolution for the IT world. This open source project is already making a lot of changes on how developers and system administrators set up a new server and web environments. If you never heard about Docker, I’ll try to explain it in a couple of lines with Wikipedia’s help:
Docker is an open-source project that automates the deployment of applications inside software containers, providing that way an additional layer of abstraction and automatization of operating system–level virtualization on Linux.Docker uses resource isolation features of the Linux kernel such as cgroups and kernel namespaces to allow independent “containers” to run within a single Linux instance, avoiding the overhead of starting virtual machines.
Docker is based on Linux Containers (LXC) and it’s actually not a substitute of your virtual machine but a way to create and manage different environments inside a server, with lightweight containers that are totally isolated from the operating system of the host machine and can be easily moved to other physical machines or VM.
We just published an online course dedicated to Docker. Our author, David Clinton, is now working on a second course that will be titled “Advanced Docker” and we’ll show how to use Docker with a public cloud environment like Amazon Web Services.
At CloudAcademy.com we do our best to teach our members’ new cloud computing skills. Docker is not a formal cloud computing topic but it’s a real revolution and something that companies and organizations worldwide are using to speed up their development process and management of their virtual infrastructures. Docker itself is not a new paradigm, and you don’t have to think about Docker as a substitute for your cloud computing platform (public or private) or for your virtualization strategy.
By the way, Janakiram did a great job describing, in details, how Docker works.
There are 3 reasons that come to my mind about why Docker will be important skills:
We are going to release our next course on Docker in a few weeks.
Stay tuned!
