The best of Tectonic combined with OpenShift

Red Hat recognizes that CoreOS has worked tirelessly over the last four years to deliver one of the best enterprise Kubernetes distributions available on the market in Tectonic. Today, both teams are working hard to incorporate the best components of Tectonic into Red Hat OpenShift® Container Platform.

As our new, converged product roadmap takes shape, our primary focus will be bringing to market the most powerful, secure and manageable enterprise Kubernetes platform. The defining features you have come to associate with Tectonic—automated operations, Open Cloud Services, built-in Prometheus monitoring, an administrator-centric infrastructure, and more—will join OpenShift’s rich services and application- and developer-centric platform.

Throughout this ongoing integration process, we promise to leave no customer or community behind.

We believe Red Hat and CoreOS are a natural fit. CoreOS’s expertise expands Red Hat’s technology leadership in containers and Kubernetes and we expect to enhance core platform capabilities in OpenShift, Red Hat Enterprise Linux and Red Hat’s integrated container portfolio. Bringing CoreOS’s technologies to the Red Hat portfolio can help further automate and extend operational management capabilities for OpenShift administrators and drive greater ease of use for end users building and managing applications on the OpenShift platform. Our focus is on improving security and enabling application portability across the hybrid cloud. We plan to share more specifics for our plans for CoreOS’s integration into the Red Hat portfolio, including OpenShift, in the coming months.

CoreOS’s products are a natural addition to Red Hat’s container solutions in a number of ways:

  • Tectonic and its investment in the Kubernetes project that it is based on are complementary to Red Hat OpenShift and Red Hat’s own investments in Kubernetes. CoreOS can further extend Red Hat’s leadership and influence in the Kubernetes upstream community and also bring new enhancements to Red Hat OpenShift around automated operations and management.
  • Container Linux and its investment in container-optimized Linux and automated “over the air” software updates are complementary to Red Hat Enterprise Linux, Red Hat Enterprise Linux Atomic Host and Red Hat’s integrated container runtime and platform management capabilities. Red Hat Enterprise Linux’s content, the foundation of our application ecosystem, will remain our primary Linux offering. Whereas, some of the delivery mechanisms pioneered by Container Linux will be reviewed by a joint integration team and reconciled with Atomic.
  • Quay brings expanded registry capabilities that can both enhance OpenShift’s integrated registry component and the Red Hat Container Catalog and be used as a standalone component.
Both Red Hat and CoreOS have been part of the Kubernetes community since Google launched the project in mid-2014. Red Hat standardized on Kubernetes for OpenShift Container Platform, Red Hat’s enterprise-grade Kubernetes container application platform, which launched in 2015. While Google and Red Hat are the top two overall corporate contributors to Kubernetes, CoreOS is also a major contributor, contributing core components like etcd, the distributed key-value store for Kubernetes, and leading multiple Kubernetes Special Interest Groups (SIGs). CoreOS also contributes to other Cloud Native Computing Foundation (CNCF) projects such as Prometheus and rkt and is part of the the CNCF governance board with Red Hat. CoreOS and Red Hat are also founding members of the Open Container Initiative (OCI) and helped drive the OCI container runtime and image format 1.0 specifications. CoreOS also created rkt, an application container engine, donated to the CNCF, that helped influence the current OCI standard.
Most of CoreOS’s offerings are already open source today. Red Hat has long shown its commitment to open-sourcing the technology it acquires when it is not open source, and we have no reason to expect a change in this approach. Our specific plans and timeline will be determined over the coming months.
Yes. Red Hat has a long history of successfully guiding open source communities for the benefit of all members. CoreOS contributes to Kubernetes and leads multiple other communities and community members can feel confident that Red Hat will continue to foster CoreOS’s vibrant ecosystem. As we open source any other technologies in the future, we plan to support those communities as well.

CoreOS will continue to honor subscriptions and provide service and support as required through and following the closing of the acquisition. We believe that CoreOS customers will benefit from industry-leading container and Kubernetes solutions, a broad portfolio of enterprise open source software, world-class support and an extended partner network.

Customers should continue to contact CoreOS support via CoreOS's support page and as that changes in the future, they will be notified ahead of time.

CoreOS and Red Hat share a deep commitment to their partners and the belief that partners are vital to our success. Red Hat looks forward to the opportunity to collaborate with CoreOS’s partners.
