A Site Reliability Engineer (SRE) is a person that operates an application by writing software. They are an engineer, a developer, who knows how to develop software specifically for a particular application domain. The resulting piece of software has an application's operational domain knowledge programmed into it.

Our team has been busy in the Kubernetes community designing and implementing this concept to reliably create, configure, and manage complex application instances atop Kubernetes.

KubeCon is on our minds in November, but it won't be the only show this month! Come see us at the following events:

Today we announce the release of version 1.4 of CoreOS Tectonic, our enterprise distribution of Kubernetes. Tectonic v1.4 incorporates self-hosted cluster technology, fixes a critical security vulnerability, and streamlines the user experience with our bare metal Installer, Console, and Identity services.

CoreOS is going to KubeCon! KubeCon / CloudNativeCon is the conference with Kubernetes leaders, users, and community members taking place November 7-8 in Seattle. Come see our talks, visit our booth, and join us for our evening events. We have six speakers giving 10+ talks, so you'll have plenty of opportunities to learn more from our experts. If you are interested in meeting 1:1 with someone on our team, submit a request.

During OpenStack Summit Austin, we partnered with Intel in an initiative aiming to automate and orchestrate the deployment and management of OpenStack with Kubernetes. Today, we are pleased to announce a technical preview of the project affectionately called "Stackanetes", available with the latest OpenStack release, "Newton". This tech preview of OpenStack on Kubernetes provides high availability with simple scaling and control plane self-healing, virtual machine live migration, and the full complement of OpenStack IaaS features – deployed, managed, and scaled with Kubernetes automation.

A critical security bug has been found and fixed in Kubernetes TLS client authentication. This vulnerability affects Kubernetes v1.4.2 and older, and has been fixed in Kubernetes v1.4.3 and higher.

Identifying Affected Systems

To determine if a Kubernetes cluster is currently running a vulnerable version, run:

The "Dirty COW" privilege escalation vulnerability in the Linux kernel, as reported in CVE-2016-5195, has been patched in CoreOS Linux. The update is currently rolling out to the Alpha (1192.2.0), Beta (1185.2.0) and Stable (1122.3.0) channels.

Today we are announcing our first round of speakers and sponsors for Tectonic Summit, the premier event for enterprise Kubernetes. Happening in New York on December 12 and 13 at the Conrad Hotel, the conference gathers leaders in cloud computing, engineering, infrastructure, operations and DevOps to explore the business implications of adopting Kubernetes in an enterprise environment. Speakers will share their stories of evaluating and using container management systems like Kubernetes.

Earlier today, we announced that Redspread has joined the CoreOS team.

CoreOS Tectonic enables everyone to operate their server systems like Google does; we call this GIFEE (Google’s Infrastructure For Everyone). Built on Kubernetes, the production-grade container orchestration system, Tectonic enables you to manage complex containerized application infrastructure from application source code to live load balancer.
