CoreOS

Container Linux is an open-source lightweight operating system based on the Linux kernel and designed for providing infrastructure to clustered deployments, while focusing on automation, ease of application deployment, security, reliability and scalability.

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.

FAQ

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.

Bringing CoreOS technology to Red Hat OpenShift to deliver a next-generation automated Kubernetes platform

In the months since CoreOS was acquired by Red Hat, we’ve been building on our vision of helping companies achieve greater operational efficiency through automation. Today at Red Hat Summit we’ve outlined our roadmap for how we plan to integrate the projects and technologies started at CoreOS with Red Hat’s, bringing software automation expertise to customers and the community.

Enterprise Kubernetes users can greatly benefit from the planned addition of many popular Tectonic features to Red Hat OpenShift Container Platform, the industry’s most comprehensive enterprise Kubernetes platform. Quay, the leading container registry, is now backed by Red Hat as Red Hat Quay. Container Linux will continue to provide a free, fast-moving, and automated container host, and is expected to provide the basis for new operating system projects and offerings from Red Hat. And open source projects including etcd, Ignition, dex, Clair, Operators and more will continue to thrive as part of Red Hat’s commitment to driving community innovation around containers and Kubernetes.

Essentially, CoreOS technologies are being woven into the very fabric of Red Hat’s container-native products and projects and we are excited to continue delivering on the vision to make automated operations a reality.

The original container-native Linux

Since Red Hat’s acquisition of CoreOS was announced, we received questions on the fate of Container Linux. CoreOS’s first project, and initially its namesake, pioneered the lightweight, “over-the-air” automatically updated container native operating system that fast rose in popularity running the world’s containers.

With the acquisition, Container Linux will be reborn as Red Hat CoreOS, a new entry into the Red Hat ecosystem. Red Hat CoreOS will be based on Fedora and Red Hat Enterprise Linux sources and is expected to ultimately supersede Atomic Host as Red Hat’s immutable, container-centric operating system.

Red Hat CoreOS will provide the Foundation for Red Hat OpenShift Container Platform, Red Hat OpenShift Online, and Red Hat OpenShift Dedicated. Red Hat OpenShift Container Platform will also, of course, continue to support Red Hat Enterprise Linux for those who prefer its lifecycle and packaging as the Foundation for their Kubernetes deployments.

Current Container Linux users can rest easy that Red Hat plans continue investing in the operating system and community. The project is an important base for container-based environments by delivering automated updates with strong security capabilities, and as a part of our commitment and vision we plan to support Container Linux as you know it today for the community and Tectonic users alike.

Integrating Tectonic Automated Operations Into OpenShift

CoreOS Tectonic was created with a vision of a fully automated container platform that would relieve many of the burdens of day-to-day IT operations. This vision will now help craft the next generation of Red Hat OpenShift Container Platform, providing an advanced container experience for operators and developers alike.

With automated operations coming to OpenShift, IT teams will be able to use the automated upgrades of Tectonic paired with the reliability, support, and extensive application development capabilities of Red Hat OpenShift Container Platform. This makes managing large Kubernetes deployments easier without sacrificing other enterprise needs, including platform stability or continued support for existing IT assets.

We believe this future integrated platform will help to truly change the way IT teams deliver applications by providing speed to market through consistent deployment methods and automated operations throughout the Stack.

In the meantime, current Tectonic customers will continue to receive support and updates for the platform. They can also have confidence that they will be able to transition to Red Hat OpenShift Container Platform in the future with little to no disruption, as almost all Tectonic features will be retained in Red Hat OpenShift Container Platform.

Automated Applications via the Operator Framework

We are also focusing on automating the application layer of the Stack. At KubeCon we introduced and open sourced the Operator Framework. Today we are showing how we plan to put Operators into practice. Red Hat is working on a future enhancement that will enable software partners to test and validate their Operators for Red Hat OpenShift Container Platform. More than 60 software partners have committed to supporting the Kubernetes Operator Framework initiative introduced by Red Hat, including Couchbase, Dynatrace, Black Duck Software and Crunchy Data, among others.

Our aim is to make it easier for ISVs to bring cloud services, including messaging, big data, analytics, and more, to the hybrid cloud and to address a broader set of enterprise deployment models while avoiding cloud lock-in. Eventually, Red Hat plans to extend the Red Hat Container Certification with support for Operators as tested and validated Kubernetes applications on Red Hat OpenShift. With the Operator Framework in place, software partners have a more consistent, common experience for delivering services on Red Hat OpenShift, enabling ISVs to bring their offerings to market more quickly on any cloud infrastructure where Red Hat OpenShift runs.

The Quay container registry becomes Red Hat Quay

Quay, the container registry, will also continue to live on in the Red Hat container portfolio.

While OpenShift provides an integrated container registry, customers who require more comprehensive enterprise grade registry capabilities now have the option to consume Quay Enterprise and Quay.io from Red Hat. Quay includes automated geographic replication, integrated security scanning with Clair, image time machine for viewing history, rollbacks and automated pruning, and more. Red Hat Quay is available both as an enterprise software solution and as a hosted service at Red Hat Quay.io, with plans for future enhancements and continued integration with Red Hat OpenShift in future releases.

With CoreOS now part of the Red Hat family, we’ve been busy working together to bring more capabilities to enterprise customers, and more muscle to community open source projects. We’re excited to work alongside you with our Red Hat fedoras on to help automate your infrastructure, all the way from the Stack to the application layer.
