CoreOS Launches Rkt Container Runtime 1.0

A new open source container runtime for Linux is on the way, courtesy of the CoreOS team. The company, which aims to help improve the security and reliability of the Internet by developing open source server infrastructure, says the new runtime promises to be more secure and more efficient than other Linux container runtimes.
