The latest News and Information on Containers, Kubernetes, Docker and related technologies.
Earlier this month the Kubernetes project discovered a security issue affecting multitenant clusters: If a potential attacker can already create or edit services and pods, then they may be able to intercept traffic from other pods (or nodes) in the cluster. An attacker that is able to create a ClusterIP service and set the spec.externalIPs field can intercept traffic to that IP.
Today, I am excited to announce project Harvester, open source hyperconverged infrastructure (HCI) software built using Kubernetes. Harvester provides fully integrated virtualization and storage capabilities on bare-metal servers. No Kubernetes knowledge is required to use Harvester. In the past few years, we’ve seen many attempts to bring VM management into container platforms, including our own RancherVM, and other solutions like KubeVirt and Virtlet.
Prometheus is an essential element in DevOps. It has one of the largest contributor communities in the open source world and is the favorite database for time-series metrics data. It is also part of Logz.io’s complete observability package, which integrates open source grafana, Jaeger, and ELK Stack into one platform. It’s a favorite for system and container monitoring. This tutorial will show you how Prometheus works with Docker and your local machine.
The Domain Name System (DNS) is a naming system for computers, services, or other resources connected to the Internet or a private network. DNS translates domain names to the numerical IP addresses needed for locating and identifying computer services and devices. For decades It’s been an essential component of the Internet. It’s an essential part of Kubernetes as well, and is used to determine how workloads connect to Kubernetes services as well as resources outside the cluster.
On December 9th, 2020, I had the pleasure of speaking with two great minds on the topic of simplifying storage in Kubernetes. Alex Chircop is the Founder and CEO at StorageOS (https://storageos.com), and Bruno Andrade is the Founder and CEO at Shipa (https://www.shipa.io). The full recording of this discussion is below. Here is a summary of what we discussed: Simplify Deploying and Operating Stateful Applications within Kubernetes
It’s re:invent season already, and we had exciting news to announce with Amazon this year. With all these remote sessions, what’s better than a quick lab to play with the new stuff? It’s starting to feel like Christmas already! We’re going to kill two birds with one stone (just an idiom, keep reading) and experiment with two of our latest announcements.
