Happy 2nd Epoch CoreOS Linux

Today we rolled out the 735.0.0 release of CoreOS Linux to the alpha channel. Our CoreOS Linux version numbers are counted from our epoch on July 1, 2013, which means this month marks the end of our second year working on CoreOS Linux.

Two years ago we started this journey with a vision of improving the consistency, deployment speed and security of server infrastructure. In this time we have kicked off a rethinking of how server OSes are designed and used. In a recent article InfoWorld said:

CoreOS Linux “was the first influential micro operating system designed for today’s cloud environments.”

Last year, we celebrated our first stable channel release and since then we have been hard at work pushing important bug fixes and feature releases to that channel every 2.5 weeks on average.

CoreOS Second Epoch

CoreOS Year 1 Highlights

In the post for that first stable release we highlighted our progress to date:

  • CoreOS engineers contributed features and fixes to open source projects including Docker, the Linux kernel, networkd, systemd and more
  • Official CoreOS image added to Google Compute Engine, Rackspace, Amazon
  • Joined the Docker Governance Board as a Contributing Member
  • Today’s most respected technology companies and many Fortune 500 companies are using and testing CoreOS in their environments

CoreOS Year 2 Highlights

In the tradition of that post one year ago, let’s take a look at some of the highlights from the last year of CoreOS.

  • Announced Tectonic, a commercial Kubernetes platform that combines the CoreOS stack with Kubernetes to bring companies Google-style infrastructure
  • Worked with community partners to create App Container (appc), a specification defining a container image format, runtime environment and discovery protocol, to work towards the goal of a standard, portable shipping container for applications
  • Created rkt, a container runtime designed for composability, security and speed and the first implementation of appc
  • joined CoreOS to provide Enterprise Registry, delivering secured hosting of your container repositories behind the firewall
  • Released etcd 2.0, which powers important projects in the container and distributed systems ecosystem including the flannel, locksmith, fleet and Kubernetes projects. etcd also supports community projects like HashiCorp’s Vault, and Docker 1.7s networking backend.
  • Joined forces with industry leaders to launch the Open Container Project, chartered to establish common standards for software containers

Our ability to build and ship innovative and high-quality projects is due in large part to the feedback and interest from our community. Thank you for all of your help in contributing, bug testing, promoting and learning more about what we are doing here at CoreOS.
