Container Tidbits: Adding Capabilities to a Container

A few weeks ago, I wrote a blog on removing capabilities from a container. But what if you want to add capabilities?

While I recommend that people remove capabilities, in certain situations users need to add capabilities in order to get their container to run.

One example is when you have a app that needs a single capability, like an Network Time Protocol (NTP) daemon container that resets the system time on a machine. So if you wanted to run a container for an ntp daemon, you would need to do a --cap-add SYS_TIME. Sadly, many users don’t think this through, or understand what it means to add a capability.

PCI Series: Requirement 7 – Restrict Access to Cardholder Data by Business Need to Know

This is my sixth post dedicated to the use of Identity Management (IdM) and related technologies to address the Payment Card Industry Data Security Standard (PCI DSS).  This specific post is related to requirement seven (i.e. the requirement to restrict access to cardholder data by business need to know).  The outline and mapping of individual articles to the requirements can be found in the overarching post that started the series.

Section 7 of the PCI DSS standard talks about access control and limiting the privileges of administrative accounts.  IdM can play a big role in addressing these requirements.  IdM provides several key features that are related to access control and privileged account management.  The first one is

Red Hat IT runs OpenShift Container Platform on Red Hat Virtualization and Ansible

Red Hat IT makes extensive use of our own product offerings to effectively manage and to scale our large IT infrastructure. Red Hat Virtualization plays a key role in Red Hat’s overall IT infrastructure, as mentioned in a recent blog by the head of our IT Platform Operations team, Anderson Silva: Red Hat Keeps the Lights on with Red Hat Virtualization

Observations from ARM TechCon 2016

Two weeks ago, I attended ARM TechCon, the annual developer conference showcasing the latest offerings from ARM and its partners.  There were a lot of new products (new and improved processor cores, radios and other IP), announcements with key themes around IoT (Internet of Things), mobile, security, automotive functional safety, and embedded software development.  This was the first TechCon after ARM was acquired by Softbank for $32B this summer, so there was great interest in hearing what Masayoshi Son (Chairman & CEO of Softbank) would say in his first public appearance with ARM.  Masayoshi Son talked about

Now Available: Red Hat Certificate System 9.1 & Red Hat Directory Server 10.1

Today we are pleased to announce the release of Red Hat Certificate System 9.1 and Red Hat Directory Server 10.1, both supported on Red Hat Enterprise Linux 7.3.

Red Hat Certificate System, based on the open source PKI capabilities of the Dogtag Certificate System, is designed to provide Certificate Life Cycle Management (i.e. to issue, renew, suspend, revoke, archive/recover, and manage the single and dual-key X.509v3 certificates needed to handle strong authentication, single sign-on, and secure communications).

Red Hat Directory Server is an open source LDAP-compliant server that centralizes application settings, user profiles, group data, policies, and access control information in a network-based registry based on the 389 Directory Server project. The Red Hat Directory Server simplifies user management by eliminating data redundancy and automating data maintenance. Red Hat Directory Server also improves security, enabling administrators to store policies and access control information in the directory for a single authentication source across enterprise or extranet applications.

Red Hat Virtualization: Bridging the Gap with the Cloud and Hyperconverged Infrastructure

Red Hat Virtualization offers a flexible technology for high-intensive performance and secure workloads. Red Hat Virtualization 4.0 introduced new features that enable customers to further extend the use case of traditional virtualization in hybrid cloud environments. The platform now easily incorporates third party network providers into the existing environment along with other technologies found in next generation cloud platforms such as Red Hat OpenStack Platform and Red Hat Enterprise Linux Atomic Host. Additionally, new infrastructure models are now supported including selected support for hyperconverged infrastructure; the native integration of compute and storage across a cluster of hosts in a Red Hat Virtualization environment.

Container Tidbits: Understanding the docker-latest Package

Does your team want to move as quickly as possible? Are you and your development team looking for the latest features and not necessarily optimizing on stability? Are you just beginning with the docker runtime and not quite ready for container orchestration? Well, we have the answer, and it’s called the docker-latest package.

Background

About 6 months ago, Red Hat added a package called docker-latest. The idea is to have two packages in Red Hat Enterprise Linux and Red Hat Enterprise Linux Atomic Host. A very fast moving docker-latest package and a slower, but more stable package called, well of course, docker.

The reasoning is, the larger and more sophisticated your container infrastructure becomes, a more stable version is often what people want – but when split into small agile teams, or when just starting out, many teams will optimize on the latest features in a piece of software. Either way, we have you covered with Red Hat Enterprise Linux and Red Hat Enterprise Linux Atomic Host.

Arm in Arm: Explore Enterprise Server Options at ARM’s Annual Technical Conference

If you have ever wanted to learn about Red Hat’s involvement in the ARM server ecosystem, and are in the San Francisco Bay Area, this week may be a perfect opportunity. Red Hat will be exhibiting at ARM TechCon, ARM Holdings’ premier yearly show at the Santa Clara Convention center. Attendees will be presented with a variety of great technical sessions and training topics, along with expert keynotes, solutions-based Expo Theater sessions and an expo floor filled with new and emerging technologies for the datacenter.  Note that the expo floor can be accessed with the free

Red Hat Virtualization and Security

The usage of open source technologies has grown significantly in the public sector. In fact, according to a published memo, open source technologies allow the Department of Defense to “develop and update its software-based capabilities faster than ever, to anticipate new threats and respond to continuously changing requirements”. Cybersecurity threats are on the rise and organizations need to ensure that the software they use in their environments is safe. IT teams need the ability to quickly identify and mitigate breaches. They also need to deploy preventative measures and ensure that all stakeholders are protected.
