In Part 1, we created a working BIND container with local data storage. We can make changes on the local system that will get picked up in the running container. In this part, we’ll explore how we can manage the service from the host with

As a follow-up to my introduction of simple signing, I’m excited to announce that Red Hat is now serving signatures for Red Hat Container Catalog Images!
In May, Red Hat announced the Container Health Index, providing an aggregate safety rating for container images in our public registry. As part of our commitment to delivering trusted content, we are now serving signed images. This means that customers can now configure a Red Hat Enterprise Linux host to cryptographically verify that images have come from Red Hat when they are pulled onto the system. This is a significant step in advancing the security of container hosts, providing assurance of provenance and integrity and enabling non-repudiation. Non-repudiation simply means that the signer cannot deny their signature—a key security principle for digital transactions.

At the 2017 Red Hat Summit, several people asked me “We normally use full VMs to separate network services like DNS and DHCP, can we use containers instead?”. The answer is

Last week, Intel launched the new family of Intel® Xeon® scalable processors with new features such as Intel Advanced Vector Extensions 512 (Intel AVX-512), which boost performance of computationally intensive tasks, a new Intel Mesh Architecture for reduced system latency, Intel QuickAssist Technology for hardware acceleration of cryptography and data compression operations and integrated high-speed fabric with Intel Omni-Path Architecture. According to Intel,

It has been over five years since the release of Red Hat Enterprise Virtualization 3.0. In just under 3 months (September 30) it will hit the end of it’s support lifecycle, and we will retire the 3.x version. At that same time, Red Hat Virtualization 4.0 will have been out for 13 months, and 4.1 for 5 months.
If you have not yet started the upgrade plan and process from version 3 to version 4, now is the time.

Twice a year the most prominent supercomputing sites in the world get to showcase their capabilities and compete for a Top500 spot. With Linux dominating the list, Red Hat is paying close attention to the latest changes that will be announced at International Supercomputing (ISC) show in Frankfurt, Germany between June 18 to June 22, 2017.
While supercomputers of the past were often proprietary, the trend of building them out of commodity components has dominated the landscape in the past two decades. But recently the definition of “commodity“ in HPC has been morphing. Traditional solutions are routinely augmented by various acceleration technologies, cache-coherent interconnects are becoming mainstream and boutique hardware and software technologies previously reserved for highly specialized solutions are being adopted by major HPC sites at scale.
Developing new and adapting existing highly scalable applications to take advantage of the new technological advances across multiple deployment domains is the greatest challenge facing HPC sites. This is where the operating system can provide

As predicted in one of my earlier posts, more and more customers are starting to seriously evaluate and move off of third party Active Directory integration solutions. They want to use or at least consider leveraging identity management technologies available in Red Hat Enterprise Linux.
In the calls and face to face meetings as well as during customer presentations at Red Hat Customer Convergence events, Red Hat Summit, Defence in Depth and other conferences I get a lot of questions about such migration. As it is becoming a common theme, I decided to consolidate some of the thoughts, ideas, and best practices on the matter in a single blog post.

As Red Hat engineers, we are always looking to incorporate features that empower administrators and decision makers. Our goal is to enable them to be proactive, efficient, and to help them maximize value from their infrastructure.
To this end, we are currently working on how to significantly improve the reporting and metrics API in Red Hat Virtualization Manager, our management platform for virtualized resources. Until recently, Red Hat Virtualization relied on native reports and data warehouse engines to provide

Recently, I spotted a question on a mailing list asking how to move container images from an internal/build registry to a production one. To put it another way: how would you copy images from registry A to registry B? I’m going to show you a really easy way to do this with skopeo.
