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.
