Episode 234: Getting Started with OpenShift
Ask Noah Show
Fedora Core OS: A Linux Distribution for Containers
Fedora Core OS is a distribution specifically designed to run containers. The idea is that in this type of operating system, you will run everything in containers. So there's nothing else needed if I just download Fedora Core OS I have everything on my host operating system to get started with containers.
Containers are amazing but managing them one by one can be a nightmare! Steve Ovens joins us as we discuss the best way to manage container workloads with tools like OpenShift and OKD.
