As the Kubernetes ecosystem grows, new technologies are being developed that enable a wider range of applications and use cases. The growth of edge computing has driven a need for some of these technologies to enable the deployment of Kubernetes to low-resource infrastructure to the network edge. In this blog post, we are going to introduce you to one method of deploying k3OS to the edge. You can use this method to automatically register your edge machine to a Rancher instance as a control plane.

MicroK8s was first released in late 2018 and has seen significant adoption rates from developers and enterprises alike ever since. Taking increasing demand and curiosity around the topic, we have already given an introduction to MicroK8s as well as covered how to deploy MicroK8s locally in previous blog posts. This time, we’ll take a look at MicroK8s’ applied value, by examining common MicroK8s use cases. Among others, this includes AI/ML workflows.

Kubernetes has a lot of features and deployment options for running containers. One of these is the StatefulSet. In this blog post, we’ll discuss what a StatefulSet is, what it can be used for, and how to create and update them.

A new vulnerability, CVE-2020-8557, has been detected in kubelet. It can be exploited by writing into /etc/hosts to cause a denial of service. The source of the issue is that the /etc/hosts file mounted in a pod by kubelet is not included by the kubelet eviction manager, so it’s not taken into account when calculating ephemeral storage usage by a pod.

Rancher has helped thousands of organizations manage their transitions to containerized applications and Kubernetes. With its innovative distribution and suite of services, Rancher has given IT and DevOps teams the roadmap they needed to drive Kubernetes success. Given the complexity of Kubernetes and the shortage of engineers with Kubernetes-specific skills, Rancher’s offerings meet a critical and growing market need.
