September 2020 Online Meetup - What's New with K3s?

If you haven't heard, Rancher's K3s was accepted last month as a Sandbox Project by the CNCF! Exciting things have been underway with K3s and in this September's meetup we will bring you up to speed on all of them. We’ll discuss the donation of K3s to the CNCF and talk about the changes you can expect to see as part of this move. Rancher experts will also cover the features and enhancements available in the 1.19 release. The focus of the 1.19 release has been improved configurability and operations for K3s clusters.

Rancher Online Meetup - December 2020: Open Source Hyperconverged Infrastructure

Learn about a new project we’ve been working on at Rancher Labs! Harvester is a virtualization and HCI platform that uses open-source hypervisors and other CNCF technologies to produce a seamless experience for administrators of complex environments that depend on Virtual Machines. Join Harvester’s principal engineer Sheng Yang and product manager William Jimenez as they walk you through the new tech.

Mitigating Kubernetes Security Vulnerability when using ExternalIP Services (CVE-2020-8554)

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.

Application Modernization

Application modernization is an inevitable transition for enterprises with a futuristic business plan. It begets new capabilities and scalability with its new flexible environment. ZiniosEdge helps enterprises to modernize their infrastructure and legacy application with advanced cloud technologies. ZiniosEdge offers application modernization process guide, architecture assessment, design, and execution plan. Plus we will help to facilitate application cloud deployment using #Containers #Microservices #Kubernetes.

Announcing Harvester: Open Source Hyperconverged Infrastructure (HCI) Software

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.

An Open Source Prometheus Tutorial for System and Docker Monitoring

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.

Automated, Simplified DNS Troubleshooting for Kubernetes: Only in Calico Enterprise

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.

Simplifying Storage in Kubernetes

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

Use Amazon ECR Public and EKS-D to deploy LTS Docker Images

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.
