The CoreOS rkt container engine is designed for security and production deployment scenarios.

This video shows how to use rkt’s modular stage1 isolation mechanism to choose the process isolation model that makes the most sense for your application. By executing alternate stage1s, you can either expose more host resources to your application, or segment it away from your host further by running it inside of a rkt-managed virtual machine.

At CoreOS, we believe strongly that open standards are key to the success of the container ecosystem. We are excited about the amount of work going into standards and foundations around containers and cloud native computing, including today’s announcement of the Open Container Initiative’s (OCI) formalized technical governance structure.

Today we’re pleased to announce that CoreOS, Docker, and a large group of industry leaders are working together on a standard container format through the formation of the Open Container Project (OCP). OCP is housed under the Linux Foundation, and is chartered to establish common standards for software containers. This announcement means we are starting to see the concepts behind the App Container spec and Docker converge. This is a win for both users of containers and our industry at large.

Today is the inaugural CoreOS Fest, the community event for distributed systems and application containers. We at CoreOS are here to celebrate you – those who want to join us on a journey to secure the backend of the Internet and build distributed systems technologies to bring web scale architecture to any organization.

Today VMware shipped rkt, the application container runtime, and made it available to VMware customers in Project Photon. VMware also announced their support of the App Container spec, of which rkt is the first implementation.

A core principle of the App Container (appc) specification is that it is open: multiple implementations of the spec should exist and be developed independently. Even though the spec is young and pre-1.0, it has already seen a number of implementations.

Today we're announcing the next release of Rocket and the App Container (appc) spec, v0.3.1.

rkt Updates

This release of rkt includes new user-facing features and some important changes under the hood which further make progress towards our goals of security and composability.

First, the rkt CLI has a couple of new commands:

Last week we announced an initial version of the "App Container Spec", a proposed standard for building and running application containers, along with a prototype implementation called Rocket.
