Today CVE-2019-5736 was announced which impacts all known versions of runc. Runc is the underlying component that creates containers in Docker, Kubernetes, and many other container systems. The full details of this vulnerability are available in the Openwall oss-security mailing. Due to the severity of this issue, exploits will not be published for another week, giving people time to patch.

Serverless has, for the last year or so, felt like an easy term to define: code run in a highly managed environment with (almost) no configuration of the underlying computer layer done by your team. Fair enough, but what is is a serverless application? A Lambda isn’t an app by itself, heck, it can’t even communicate with the world outside of Amazon Web Services (AWS) by itself, so there must be more to a serverless app than that.

The open source revolution is back in full swing with the rise of Kubernetes. Flexibility and agility are the key factors to making the most of the cloud, multicloud, or hybrid cloud era. Kubernetes makes that easier by granting DevOps teams greater control across their infrastructure. But easier does not necessarily mean easy — there are still hurdles to overcome.

There’s no shortage of providers willing to host your containers. Many of the world’s biggest cloud platforms offer Kubernetes as a service, including features such as automatic scalability and high availability. However, Google Cloud Platform (GCP) stands out as perhaps the best tool for building and hosting a Kubernetes cluster for a number of reasons. In this article, we’ll present these reasons and why GCP offers a better Kubernetes experience than other providers.

I’m excited to announce the release of Rancher 2.2 Preview 2, which contains a number of powerful features for day two operations on Kubernetes clusters. Please visit our release page or the release notes to learn more about all of the features we shipped today. In this article I introduce one of the features: multi-cluster applications. Read on to learn how this will dramatically reduce your workload and increase the reliability of multi-cluster operations.

In a previous post, we explained the concept of configuration management and presented three of the most popular tools: Chef, Puppet, and Ansible. We also briefly explored the impact that containerization is having on configuration management, and how the two can be used in combination. This article takes a more in-depth look at this relationship by presenting different techniques for using Chef, Puppet, and Ansible to deploy and manage a Kubernetes cluster.
