CoreOS joins Red Hat

Copiar URL

Red Hat and CoreOS share the same vision for our users: greater security and operational efficiency for Kubernetes workloads through automation. Together, we’re delivering open source, cloud-native innovation and a leading hybrid cloud, enterprise Kubernetes platform.


Projects and community

CoreOS and Red Hat have long worked to extend the capabilities of Linux® containers and Kubernetes, leading development of open source projects to help users build and operate more secure applications through automation. Open source projects started as part of CoreOS will continue to develop, in collaboration with the wider cloud-native community.

Operators + Operator Framework

Use the Kubernetes API to create, configure, and automatically manage applications.


Public registry for finding Kubernetes Operator backed services.


Distributed, reliable key-value store for the most critical data of a distributed system. Now part of the CNCF.


First boot installer and configuration tool designed for Container Linux.


Network fabric for containers, designed for Kubernetes.


Automatic container vulnerability and container scanning for containers.


OpenID Connect Identity (OIDC) and OAuth 2.0 Provider with Pluggable Connectors.

Container Networking Interface (CNI)

Networking for Linux containers. Now part of the CNCF.


CoreOS has joined Red Hat to build leading enterprise container platform and solutions:


CoreOS Container Linux, the pioneering lightweight container host, has merged with Project Atomic to become Red Hat Enterprise Linux CoreOS. Red Hat Enterprise Linux CoreOS combines the ease of over-the-air updates from Container Linux with the Linux kernel to deliver a more secure, easily managed container host. Red Hat Enterprise Linux CoreOS is available as part of Red Hat OpenShift.


CoreOS Tectonic, envisioned as a fully-automated container platform, is merging with Red Hat OpenShift. The streamlined installation and automatic, over-the-air updates that originated with Tectonic are now paired with the reliability, support, and developer experience in OpenShift in a leading, hybrid cloud enterprise Kubernetes platform.


Container registry

The Quay container registry is now Red Hat Quay, and available as a self-hosted and managed service offering. While Red Hat OpenShift includes an integrated container registry, Quay offers customers more comprehensive capabilities, such as geographic replication, image rollback, and automated image pruning.


Frequently asked questions

Where can I find documentation for CoreOS products?

Quay documentation has been migrated to the Red Hat customer portal. Documentation for CoreOS Tectonic and Container Linux will continue to live on coreos.com until end of life for commercial support for these products, at which point documentation will be archived and publicly accessible at their respective GitHub repositories.


How can I continue to get security notifications for CoreOS products and projects?

Please follow @CoreOSSecurity on Twitter for updates. Community users may report any security matters related to CoreOS projects via email or at coreos.com/security/disclosure.


How can I remain involved with projects that originated from CoreOS?

Red Hat and CoreOS are proud to support container and Kubernetes technology projects. These projects will continue to be hosted at their existing repositories on GitHub, and Red Hat will continue its development in key, upstream projects such as etcd, Container Linux, and the Operator Framework.


What happened to the CoreOS blog and press releases?

The CoreOS blog will remain at coreos.com/blog for the time being, but will later be archived on the openshift.com site. No new content will be published to the CoreOS blog.  Similarly, CoreOS press releases will continue to be publicly available at coreos.com/press/ until they are also migrated to the openshift.com site.
