Red Hat OpenShift

One of the greatest advantages of using docker containers is the fact that you can move them between environments. A promotion from Development to a Production environment, shouldn’t take more than some few seconds. This is one aspect of “Continuous Delivery” Because Microservices Architectures are “independently replaceable and upgradeable”, they are the best scenario to show a “Deployment Pipeline”. Red Hat Developers has produced a sample and free application called “Red Hat Helloworlds MSA” that demonstrates different aspects of microservices...

Running .NET on Linux, using the Red Hat Container Development Kit (CDK), means your Linux VM is running "headless" -- you don't have a desktop UI. You have a command line, and that's it. Note: If you aren't running .NET on Linux, hop over to the Red Hat Developer's web page and download the CDK to get started. Red Hat Enterprise Linux's built-in editor, VIM, which is launched by the command vi, is not a full-featured development environment. Not even...

Ansible serves as a great tool for those system administrators who are trying to automate the task of system administration. From automating the task of configuration management to provisioning and managing containers for application deployments, Ansible makes it easy. In this article, we will see how we can use Ansible to provision Vagrant boxes. So, what exactly is a Vagrant box? In simple terms, we can think of a vagrant box as a virtual machine prepackaged with the development tools...

The Red Hat Developer Program was introduced to make it easier for any developer to create quality software. The program began with great developer tools and content provided through our developers.redhat.com website, which allows developers to download and use our enterprise products for development purposes through a free membership. This enables you to develop, prototype, test, and demo your software on the enterprise products that can be trusted to run the most demanding of enterprise production environments. Here are the...

https://www.youtube.com/watch?v=MrV0DqTqpFU The challenge of data with microservices Of the reasons we attempt a microservices architecture, chief among them is allowing your teams to be able to work on different parts of the system at different speeds with minimal impact across teams. So we want teams to be autonomous, capable of making decisions about how to best implement and operate their services, and free to make changes as quickly as the business may desire. If we have our teams organized to...

In a previous post, where-have-all-my-subscriptions-gone, I mentioned that you can access the Red Hat Content Delivery Network (CDN) using its API --- allowing you to query CDN for subscriptions and their usage, registered hosts, and more as well as unregistering hosts, and more. I wanted to do some analysis for my own subscription usage, so I wrote some scripts that let me more easily tell where my subscriptions are being used. Since Python scripting is still fairly new to me...

As you may recall, Red Hat recently announced support for a common language server protocol. Furthermore, we demoed our initial implementation for a Java language server during the DevNation keynote. I posted an earlier blog covering these topics, and I would like to do an update in this post on the progress we've made since DevNation. While preparing for DevNation, we had the idea that it would be a good feature boost if the engineering teams from Red Hat, Microsoft...

One of my favourite books is Antifragile by Nassim Taleb where the author talks about things that gain from disorder. Nacim introduces the concept of antifragility which is similar to hormesis in biology or creative destruction in economics and analyses it charecteristics in great details. If you find this topic interesting, there are also other authors who have examined the same phenomenon in different industries such as Gary Hamel, C. S. Holling, Jan Husdal. The concept of antifragile is the...

The recent WG21 meeting in Oulu, Finland, was an especially busy one for the Library Working Group. Every day was spent working through the list of proposals intended for inclusion in C++17, and we also had three "evening" sessions that ran well past the evening (until nearly midnight, although the sun was still up to trick us into working late). This post describes what I think are the most important library features that were reviewed and approved for inclusion in...

It was quite a trek to get to Oulu, Finland for the June 2016 C++ Standards Committee meeting, but we were warmly received and the meeting went well once we arrived. We had very pleasant weather most of the week, and it was fun to experience the midnight sun, even though it played havoc with my sleep schedule. The main order of business at this meeting was to vote on a first Committee Draft (CD) of the (expected) C++17 standard...

There’s a whole host of GUI tools to connect to MongoDB databases and browse, however despite a steeper learning curve, I’ve always found myself more productive using a command line interface (CLI). Then, there’s that moment when something has gone wrong on the database server, and we need to SSH 4-levels deep in order to debug a problem with a database. Sometimes, there’s no other option available, and this makes familiarity with the CLI invaluable. I learn best by example...

Following my introduction blog about why microservices should be event-driven, I’d like to take another few steps and blog about it. (Hopefully I saw you at jBCNconf and Red Hat Summit in San Francisco, where I spoke about some of these topics). Follow me on twitter @christianposta for updates on this project. In this article we discuss the first parts of carving up a monolith. The monolith I’m exploring in depth for these articles will be from the Ticket Monster...

As a systems engineer, I enjoy building deploying production and pre-production services. These production services tend to be built at scale in a highly redundant architecture. The problem has always been how do we give developers a sandbox that matches production in all the ways that matters-- but without the pain (and love), overhead, compute and networks resources actual production environments require. Moreover, how does one snapshot this environment so it can be recreated at will. This has been a...

Those looking to ascertain the ubiquitous nature of open source need look no further than the trajectory of .NET, Microsoft’s widely-adopted general development platform. In November 2014, Microsoft announced the open sourcing of .NET with .NET Core, a just-in-time (JIT) compiler and runtime for .NET. Then, in November 2015, Red Hat and Microsoft announced a landmark relationship, which established our collaboration with and promised access to .NET on the world’s leading enterprise Linux platform: Red Hat Enterprise Linux and Red...

"There is already a command line for it, why can't my favorite editor support this language?" As a developer, you're probably familiar with this sentiment, and in reality t here has never been a better time to be a software developer. Developers have access to a growing list of languages, frameworks, libraries, and technologies that can help them solve the problems they are tasked to tackle. However, the abundance of choices often hinders the ability of Integrated Development Environments (IDEs)...

http://www.youtube.com/watch?v=0qQ1bGoNcEs From May 10th to May 14th we arrived at Florianópolis (with a short travel to Campinas) to do what we love the most: talk to developers. We from Red Hat Developers had an amazing time with the developer community gathered together at both The Developer's Conference (TDC) Florianópolis and DevCamp. Red Hat delivered a lot of great content to the audience, with speakers presenting dozens of talks in the Java EE, Java, Cloud Computing, Architecture, DevOps and .NET tracks...

I recently had an interesting problem which served as a great learning experience. It involves hair-pulling levels of frustration, vicious finger-pointing, and an unexpected ending --- not a TV Soap opera episode, just a day in the life of a developer. It all started with a REST API I had built for a customer proof of concept that started refusing requests after an arbitrary period of time. Nothing was unusual in the codebase of the REST API --- it was...

Jenkins is great, and it has done a lot to make our lives easier. It seems like not so long ago when the idea of continuous integration tools was a daunting task. Jenkins came to the rescue, and I (and many others) use it a lot... A LOT. Given that my day to day work is in consulting, I'm constantly working in different development environments with different technologies - and a common thread among all those environments is Jenkins. It...

I've been working with some of our teams recently on microservices and how we can assist our customers and communities with best practices and recommendations, whether they're Java EE developers, Vert.x coders, writing Node.js applications or something else. If you've read any of my previous articles then you'll know I have a few thoughts on microservices, and yet there are many things I still feel I need to get straight in my own head. That's why I love talking with...
