Excerpts from the original article: "Now that Red Hat Enterprise Linux 7 is generally available , we are re-casting the Red Hat Enterprise Linux High Touch Beta program into a series of Red Hat Enterprise Linux 7 special interest groups (SIGs), the first of which is focused on application containers. The Red Hat Enterprise Linux Atomic Host SIG encompasses technologies that are required to create, deploy, and manage application containers. "We also announced today that Red Hat and Google are...

Excerpts from the original announcement: "Red Hat and Google are both committed to open source and we were both early proponents of Docker as well as key contributors to the Docker project. We are now joining forces to drive a new open standard around orchestrating Docker containers at scale for the management of cloud application deployments. "Today, Red Hat is announcing that as part of Project Atomic, we are collaborating with Google to tackle the challenge of how to manage...

Excerpts from the original article: "Red Hat announced the general availability of Red Hat Enterprise Linux OpenStack Platform 5, the third enterprise release of Red Hat's OpenStack offering, designed to serve as the foundation for building OpenStack-powered clouds for advanced cloud users, telecommunications companies, Internet service providers (ISPs), and public cloud hosting providers. "Red Hat Enterprise Linux OpenStack Platform 5 is based on the OpenStack Icehouse release and includes several new features aimed at easing enterprise adoption of OpenStack technology...

Reposted in its entirety from rhelblog.redhat.com . When Red Hat Enterprise Linux 5 was first introduced in 2007, it was done so with an expected seven year lifecycle. Five years later, in 2012, we saw the continued strong adoption of Red Hat Enterprise Linux 5 and decided to extend its seven year lifecycle to 10 years. Now, in 2014, the original retirement year for Red Hat Enterprise Linux 5, we still see an active, dedicated customer base that has come...

Red Hat Enterprise Linux 7 is now GA and so it's time to write some code and/or port your applications. So let's take a quick inventory of development tools, shall we? With RHEL, there are 2 primary sets of toolchains for you to use. First, there's base RHEL 7 tools (like RHEL 6) that will be supported with RHEL 7 for 10 years (more below). Second, there are complementary tools in Red Hat Software Collections (RHSCL) and Red Hat Developer...

Yes, you may have heard that Red Hat Enterprise Linux 7 is now generally available . ;) But here is more good news: RHEL 7 is now available in all Amazon Web Services (AWS) regions including GovCloud (US)! Here's what Amazon's Terry Wise (head of Worldwide Partner Ecosystem, Amazon Web Services) had to say in a Red Hat press release this week: “Red Hat and Amazon Web Services have worked closely together since 2007 to make Red Hat Enterprise Linux...

With April showers, comes talk about containers. (Well, not exactly, but there's a lot of container discussion going on these days.) Bhavna has produced this excellent article to summarize Red Hat's efforts on them. Here's an excerpt: "Let’s dive into world of containers. Red Hat customers often desire for their applications to run in a secure environment and have been seeking, whether they actually know it or not, a fully supported light weight application isolation solution. At the other end...

Please take a moment to give us your input and feedback on Red Hat Enterprise Linux 7 Beta. Thank you!

As Software Collections are getting popular, there are more and more people asking how they can build their own collections and/or extend collections in RHSCL. In this article, I will demonstrate how to extend python27 collection from RHSCL 1.1 (Beta), adding a simple Python extension library. I'm going to work on a RHEL 6 machine throughout this whole tutorial. I'm assuming that readers have basic knowledge of RPM building and Software Collections concept . General Notes This tutorial uses a...

Apologies that this has been so long in coming, but I was certain that we had already written a post on this subject. What subject you ask? How does one set one or more software collections as automatically enabled for your login. Some of you may consider this obvious, but there are a number of ways to accomplish this goal. First, you just "source" the enable script from your .bashrc. For example source /opt/rh/python33/enable However, as this Red Hat kbase...

Announcement: "Hortonworks and Red Hat Deepen Strategic Alliance" Here are some highlights from Monday's announcement: "Immediate initiatives that are included in the expanded Hortonworks and Red Hat strategic alliance include "Data architects will be able to combine data in a single, scalable open source repository. Available in beta software version, the Hortonworks Data Platform (HDP) combined with Red Hat Storage provides a secure and resilient general-purpose storage pool with multiple interfaces, including Hadoop, POSIX and OpenStack Object Storage (Swift). This...

Be sure to follow this new addition to the Red Hat blogosphere at: rhelblog.redhat.com . You can expect to see a great series of technical articles here.

So, yeah, it was in beta testing, but now it's generally available! See the recent Red Hat press release . If you use virtualization in your development (e.g. spinning up VMs for projects), you might find the ability to change proc counts while the guest is running useful. RHEL 6.5 virtualization also adds direct integration with GlusterFS / Red Hat Storage in case you want to play with that in a virtualized test environment. Dynamic storage is definitely getting interesting...

One of the new features for the Developer Toolset (DTS) 2.0 is Eclipse 4.3.0 (Kepler). Aside from various performance improvements to the base platform since Eclipse 4.2 (Juno) a lot of other plugins are being shipped to make life easier for development. The C/C++ Developer Tooling (CDT) is a plugin used to develop, build, run, and debug C/C++ applications in Eclipse. It has support for various toolchains, Makefile/Autotools projects, static analysis, and easy navigation of a code-base thanks to a...

Red Hat intended for developers to integrate Developer Toolset 2.0 (DTS) and Red Hat Software Collections 1.0 (RHSCL). As you may not realize, inside the DTS is a copy of Eclipse and you can use that with any software collection. In other words, you can use PyDev, with the Python 2.7 Software Collection from RHSCL in the Eclipse from DTS. Let's find out how. First, let's make sure you have the right repos, [lwhite@lwhite-laptop ~]$ sudo yum repolist Loaded plugins...

Some months ago, I developed and released a small Puppet module for tuned-adm . As this tool is a nice feature of RHEL , I think it is only fair from me to advertise about it here, on the Red Hat developer blog. Quick overview of 'tuned-adm' (Photo credit: Accretion Disc ) To make this brief, this command will take care of tuning the operating system for you, based on the usage you want to make of it. For instance...

If you have ever worked as a system administrator, you are familiar with developers constantly wanting to use the latest toolchains even to the point of wanting to roll their own packages. Of course, the challenge is, if you are running a production environment, introducing change is always risky. If the change being introduced is from an unknown source, the risk is even higher. As a result, many admins rely on companies like Red Hat to provide them some assurances...

As I discussed in an article entitled Red Enterprise Linux Release Speed , developers sometimes have a problem with how slow Red Hat's Enterprise Linux releases new versions of software. Well, the good news is, Software Collections are here. Software Collections provide Red Hat Enterprise Linux users with newer versions of programming languages and server daemons like python, perl, ruby, php, mysql, mariadb, etc. This is a quick start guide to help you get comfortable with both programming languages and...
