CI/CD

Automated testing is one of the hardest, but also the most important thing to get right when doing Continuous Delivery or DevOps. Recently Aslak Knutsen and I hosted a webinar with the title "Continuous Development with Automated Testing". The webinar had quite a few viewers (and maybe that was one of the reasons that the demo in the webinar didn't exactly go as planned.) Aslak did a great job trying to talk through a demo that played at 1/3 of...

So you finally surrendered to containers and discovered that they solve a lot of problems and have a lot of advantages : First: Containers are immutable - The OS, library versions, configurations, folders, and application are all wrapped inside the container. You guarantee that the same image that was tested in QA will reach the production environment with the same behaviour. Second: Containers are lightweight - The memory footprint of a container is small. Instead of hundreds or thousands of...

Andrew Block of Red Hat will be speaking on this topic at DevOps Enterprise on 21 October - below is a primer from him on what he'll cover: Although the DevOps movement clearly and correctly centers around culture and the processes that guide or derail our success, the root of this shift often gets overlooked in favor of the symptoms. Sure, we all want our teams better aligned and more consistent, our processes streamlined and automated, our release cycles as...

So here's are deal: We've created what we're calling "PaaS-Containers" in our IT production environment. It consists of core technologies like RHEL Atomic Host, Kubernetes, and Docker along with supporting CI/CD components like Jenkins together as part of an offering that supports the end-to-end automated deployments of applications from a code-commit event through automated testing and roll-out through multiple environments (dev, QA, stage, prod). Oh, did I mention that it's also integrated with our enterprise logging and monitoring as well...

"DevOps". If you're like me, you may be suffering a bit of buzzword fatigue , especially relating to how this word is used (or misused ) within the IT community. But for those of us who have been a part of the community for a while, it holds deeper meaning than the oft-repeated platitude of "Software Developers and Sysadmins working together, riding unicorns over rainbows ". Okay, while I may have gotten slightly carried away, you get the point. What...
