Red Hat absorbs CoreOS

The Red Hat company announced the purchase of CoreOS, a well-known to many habravchanam, and occupies a worthy place in the market of container insulation systems and associated software. The announced amount of the transaction - $ 250 million.

Among the projects developing in CoreOS that competed with Docker and Red Hat Atomic solutions are the atomically updated Linux-environment CoreOS Container Linux (which appeared on the market in 2014 under the name CoreOS). Container Linux introduced the logic of having in OS only the minimum set of components necessary to launch containers.

In addition, among CoreOS products:

• Quay Container Image Registry (with means to ensure high reliability and availability of the registry)
• rkt container management tools (which is positioned as a safer, portable and server-friendly alternative to the Docker toolkit),
• distributed storage system configurations etcd , unified configuration storage engine and information about working services for isolated containers with typical fillings.
• Tectonic container orchestration platform (based on Kubernetes),
• a distributed storage system coordinated via etcd, called Torus ,
• tools for the initial configuration of the Ignition system (providing tools similar to Cloud Init to system configuration at the initial boot stage),
• Flannel network configurator,
• dex identification service
• A system for analyzing vulnerabilities in the stuffing of the containers Clair (an interesting solution that allows for routine inspection of the contents of the containers; CVE (Common Vulnerabilities and Exposures) and Red Hat Enterprise Linux , Ubuntu, and Debian distributions are used as the data source).

Total CoreOS supports and develops more than 90 projects, many of which are presented on github . Most CoreOS products have evolved as free software, missing source code, as promised, will be open in the coming months. After completion of the transaction, Red Hat intends to integrate CoreOS technologies into its OpenShift and Red Hat Atomic products, and also to offer users a number of new products based on CoreOS developments. A plan for creating combined products and migrating existing CoreOS customers to them, including eBay and Salesforce, will be published later.

The Tectonic project, which overlaps with Red Hat's own developments related to the OpenShift and Kubernetes platforms, is planned to be used to extend the functionality of OpenShift in the field of automation of operations and management. The Quay registry is planned to continue to be used as a separate component, as well as to use related developments to improve the Red Hat Container Catalog and registry tools integrated into OpenShift.

Because Container Linux, as well as the rkt and etcd toolkits, intersect with the Red Hat Enterprise Linux Atomic Host product, platform management tools and runtime integrated for containers in RHEL. Red Hat intends to create a joint development team for reviewing, integrating, and combining Container Linux technologies with the Atomic project. Container Linux, etcd, and rkt projects have been transferred to the CNCF (Cloud Native Computing Foundation) organization, which is developing the Open Container Initiative (OCI) standard, Kubernetes platform , and runtime containerd .
