Advanced Linux Commands Cheat Sheet is Here

Before I came to Red Hat, I used to work for a Red Hat partner as a consultant and architect. During that time, I was involved in quite a few situations where I had to help people move from one platform to another, most often from some flavor of Unix to Red Hat Enterprise Linux. As Linux is the de facto standard platform for many development teams, it seemed to make sense to translate some of that experience into a document that can help others make the switch to Linux as a development platform. After the team got many requests for a more advanced version of our original Linux Commands Cheat Sheet we set off to create this document a couple of weeks ago and today we present the result: the Advanced Linux Command Cheat Sheet.

No cost. No hassle. Plenty of RHEL Developer Benefits

A year ago Red Hat announced the availability of a no-cost Red Hat Enterprise Linux developer subscription available as part of the Red Hat Developer Program. Offered as a self-supported, development-only subscription, this developer subscriptions provides you with a stable development platform for building enterprise applications – across cloud, physical, virtual, and container-centric infrastructures.

Adoption has been excellent since then, but I was prompted (aka nudged, voluntold) to remind “non users” (yes, some of you are still out there) what it is and how to get it. But I’ll also explain to “users” how to easily re-subscribe (it’s still free) if your 12-month subscription is up.  First, here’s what you “non-users” can get if you become “users”:

Containerizing open-vm-tools – Part 1: The Dockerfile and constructing a systemd unit file

While validating OpenShift Container Platform on a VMware platform the usage of Atomic OS was also a requirement. In the initial reference architecture, the decision was made to use Red Hat Enterprise Linux as the platform. This platform was then customized and the same packages as in Atomic were installed via Ansible and Red Hat Network.

Preparing CentOS 6.8 for Work

I came across Linux in 2005, it was Debian. Then followed a love affair with Ubuntu, for which in March 2009 I purchased a netbook Asus EeePC 1000. In 2010, I began to contribute to ALT Linux participating in the “School Project” and even became a basic256 package maintainer.

The last few years my EeePC with Ubuntu peacefully rested deep in my cupboard. Then there was a chance to clean off the dust. There was a task to get acquainted with CentOS Linux and test examples for my webinar “Apache Ant – quick start”.

One of the best features of Visual Studio is the ability to launch and debug an application from within the IDE. This is not an uncommon feature nowadays. When running .NET on Linux, however, you can’t use Visual Studio as your IDE. What to do?

Find what capabilities an application requires to successful run in a container

Many developers would like to run their existing applications in a container with restricted capabilities to improve security. However, it may not be clear which capabilities the application uses because the code uses libraries or other code developed elsewhere. The developer could run the application in an unrestricted container that allows all syscalls and capabilities to be used to avoid possible hard to diagnose failures caused by the application’s use of forbidden capabilities or syscalls. Of course, this eliminates the enhanced security of restricted containers. At Red Hat, we have developed a SystemTap script (container_check.stp) to provide information about the capabilities that an application uses. Read the SystemTap Beginners Guide for information on how to setup SystemTap.

How to build a containerized IoT solution with OpenShift

For businesses looking to build scalable Internet of Things (IoT) solutions using containers, here is a sample project built on the Red Hat OpenShift Container Platform. This project implements an intelligent IoT gateway on the OpenShift Container platform. The IoT Gateway is critical for enterprise IoT as it brings intelligence, and enables key services, at the edge. In this project, the gateway application is deployed as a set of microservices inside containers on OpenShift.
