Pluggability is part of the success story of Kubernetes, and as a community we have ensured that many layers – including storage, networking, and schedulers – can be replaced and improved without changing the Kubernetes user experience. Earlier this year, the Kubernetes project created an API called the Container Runtime Interface (CRI) to make the way a container is run on Kubernetes pluggable.

Tectonic 1.7.5 has arrived, and this release is all about monitoring. Container-based infrastructure is highly dynamic, which is great for agility, but enterprise-ready Kubernetes means having the right tools in place to monitor your clusters and respond quickly when problems arise. That's what Tectonic delivers.

With the release of Kubernetes 1.8, role-based access control (RBAC) has been promoted from beta to general availability. CoreOS, through our participation in the Kubernetes SIG Auth group, played a significant role in getting RBAC implemented in upstream Kubernetes. With its graduation to general availability, the feature and its core APIs can be considered stable.

October is a big month to celebrate open source! Meet us at Grace Hopper Celebration, All Systems Go, All Things Open, and Open Source Summit EU to learn about container orchestration with Kubernetes, monitoring with Prometheus, and more.

 

Security researchers have recently discovered multiple remotely exploitable vulnerabilities affecting all users of Kubernetes 1.5.0 through 1.7.6. While the risk of an attacker successfully exploiting these flaws is relatively low, the vulnerabilities could potentially allow arbitrary code execution or DoS attacks and thus demand immediate attention. CoreOS Tectonic users can be assured, however, that patches are now available and can be applied with a single click or automatically, if configured.

Today, along with the rest of the Kubernetes community, we’re cheering the release of Kubernetes 1.8. The momentum within the community continues to grow as organizations embrace Kubernetes as the leading platform for container orchestration, and this release continues the Kubernetes community's commitment to security and extensibility with work on stabilizing existing features, even as new ones are added.

A reliable key-value store gives distributed systems a common substrate for consistent configuration and coordination. One such system is the etcd project, an open source key-value store created by CoreOS. It is the heart of many production distributed systems and is the data store for Kubernetes, among other projects.

Trying CoreOS Tectonic is now as easy as downloading and installing it to your laptop. Today we are introducing the Tectonic Sandbox, a new way to see for yourself what CoreOS's enterprise-ready Kubernetes platform can do for your business. This new Sandbox joins our existing Tectonic trial experience designed for production use on multiple clouds and environments including AWS, Azure, bare metal, and more.

I'm often asked why we started CoreOS. I've written before about our mission to secure the internet. Recently, I was challenged further: Why do you care about securing the internet? This question gets at the heart of CoreOS, and deserves a well articulated answer. Securing the internet is key to preserving our privacy, and ultimately our freedoms.

Today's fast-moving enterprises have an urgent need to modernize their IT operations, and increasingly they are choosing Kubernetes as a tool to help them meet that challenge.
