With the release of Docker 1.8, Docker has replaced Boot2Docker with Docker Toolbox. Docker Toolbox provides an ideal platform environment to learn Docker without having to manually install and configure a virtual machine and Docker on your desktop.
A question I am often asked, is will containers replace virtual machines? With containers being lightweight, portable and with fast startup time, it would seem to be a no brainer. While containers are not all that entirely new, the technology has been evolving rapidly in the past few years, especially with Docker and recently with Microsoft entering the marketplace.
Plenty of new announcements at the recent DockerCon 2015, it looks to be an interesting year using containers. Below are some good articles, videos and other information on new features such as Docker 1.7, Open Containers, Security and networking improvements.
