We're proud to announce that etcd v3.3.0 is now public! This release includes backend database improvements, data corruption checking, a new client that's more tolerant of network partitions, v2 API emulation, and many more changes.

Red Hat and CoreOS logos

 

CoreOS has agreed to become a part of the Red Hat family.

Red Hat and CoreOS’s relationship began many years ago as open source collaborators developing some of the key innovations in containers and distributed systems, making automated operations a reality. Since that time, we have both become leaders in the communities that are driving these innovations, including Kubernetes, the Open Container Initiative (OCI) and the Cloud Native Computing Foundation (CNCF). Today Red Hat announced it has signed a definitive agreement to acquire CoreOS. By joining Red Hat, I believe we will make these important technologies ubiquitous in business and the world.

The ability to autoscale workloads based on metrics such as CPU and memory usage is one of the most powerful features of Kubernetes. Of course, to enable this feature we first need a method of gathering and storing these metrics. Today this is most often accomplished using Heapster, but this method can be cumbersome and support from the various contributors to the project has been inconsistent – and in fact it may soon be phased out.

New releases of Container Linux addressing the Meltdown attack, caused by vulnerabilities in many modern processors, are now available in all three Container Linux release channels: Alpha 1649.0.0, Beta 1632.1.0, and Stable 1576.5.0. Updates are rolling out to the Alpha and Beta channels now, and should complete over the next 24-48 hours. By default, Container Linux will apply these updates automatically, but systems with non-default configurations should be manually updated as soon as possible.

A recent information disclosure vulnerability (CVE-2018-5256) was found and addressed in Tectonic, which affects versions 1.7 through 1.8. Unauthenticated users were able to list all Namespaces through the Console. In 1.8, which finalized the transition from Third Party Resources (TPRs) to Custom Resource Definitions (CRDs), the ability to list all CRDs was affected by the same bug. The intention of this API endpoint is to enable listing all namespaces by logged-in users.

Today we're proud to announce Tectonic 1.8, the latest release of our enterprise-ready Kubernetes platform, is now available. This version, which we announced ahead of KubeCon + CloudNativeCon North America earlier this month, is the first to ship with a catalog of industry-first Open Cloud Services that enable users to deploy key infrastructure components with the ease of managed cloud vendor offerings but without cloud vendor lock-in.

Kubernetes is the highest velocity cloud-related open source project, and its pace of development isn't slowing down. This week the project will ship Kubernetes 1.9, its latest release, coming three months after Kubernetes 1.8. The new version includes a number of updates, fixes, and new features, as you can see in the release notes. Many of these changes are "under the hood," however – so rather than diving into a feature checklist here, it's worth looking at the overarching goals driving the next phase of Kubernetes development.

It was a jam-packed and eventful week at KubeCon + CloudNativeCon North America 2017 last week. In all, 4,100 attendees descended on Austin to talk all things Kubernetes and cloud-native, and CoreOS was front and center as a Diamond Sponsor of the event. Check out our blog post from Wednesday where we recap some of the Day 1 highlights.

KubeCon + CloudNativeCon North America 2017 is underway this week in Austin, and the CoreOS team is on the scene to participate. As a Diamond Sponsor of this year's event, we couldn't be more thrilled with the turnout of attendees and their vibrant energy.
