This article describes how to configure MongoDB’s WiredTiger memory cache in Red Hat Mobile Application Platform (RHMAP) to prevent high-usage memory issues and Nagios alerts. If the WiredTiger cache consumes all the memory available for a container, memory issues and Nagios alerts will occur. The WiredTiger storage engine is the default storage engine starting in […]
Kubernetes Container Management
Learn how Kubernetes, a powerful open-source tool, helps you develop and manage components across containers in any environment.
This DevNation Live session will provide you with a basic understanding of what Kubernetes is and how it can help you run your Linux containers at scale.
What is Kubernetes?
Kubernetes is an open-source system for managing containerized applications. Technologies like Docker deliver a container framework, but they don't deliver the scalability, deployment, and management features provided by Kubernetes. With Kubernetes, it's trivial to accomplish tasks such as "keep at least two and no more than ten copies of this container running," "start a new container if one fails," and "balance all of the traffic headed to these containers." Kubernetes makes it easy to make containers scale.

Podcast: 2018 Kubernetes Trends
In this podcast, we look ahead at what the trends will be in Kubernetes for 2018. Some of these are the new shiny things – like Service Mesh (e.g. Istio) or Serverless. Others topics look at how the Kubernetes community is evolving to deliver more manageable services (e.g. automating Operations). Finally we look the breadth of activities that are starting to evolve around the developer experience with OpenShift – lots of projects at various levels of maturity.
