Have you ever wanted to try K3s high availability cluster “mode,” and you either did not have the minimum three “spare nodes” or the time required to set up the same amount of VMs? Then you are in for a good treat: meet k3d! If you’re not familiar with k3d, its name gives you a hint to what it’s all about: K3s in Docker.

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.

As companies adopt container technologies, they face a significant challenge - how do we secure this new attack surface? It’s an issue that you often see backlogged in favor of solving storage, networking and monitoring issues. Add on the challenge of educating the workforce on one of the fastest-growing open source projects to date, and it’s no wonder security has lagged as the primary focus for teams.

Are you or your team currently looking for your next-generation architecture? Or perhaps are you already there, but looking for the best way to automate and manage it. In this blog, we’re going to talk about deploying Rancher environments using the power of env0. Rancher is a complete software stack for teams adopting containers.
