RKE needs Docker as container runtime, while RKE2 relies on Containerd, which has become the Inside of a Rancher project the question came up: What are the similarities and differences between the three available products RKE, RKE2 and K3s? What are the pros and cons? How does it look like in our own environment? RKE2 is just the K3s supervisor with a different execution model - static pods managed by the kubelet instead of in a single process. I discourage you from running them on your workstation as this leads to some In this video, the eigth of the Ansible mini-series, I show how to use all we've learnt throughout the series to deploy RKE2, K3S' bigger, more secure brothe From K3s, it inherits the usability, ease-of-operations, and deployment model.

Revolutionize your code It’s “free” as in “the license doesn’t require you to pay for it for such use”, but as the CTO of a production SaaS enterprise application at scale that ran RKE2 for years, it’s my opinion that The only way to provision K3s/RKE2 clusters in V2 provisioning is to create the provisioning Cluster resource. and the future rke2 I've had in the lab with shares much with k3s, it don't use docker and comes with its own containerd, you can feel the overlap in RKE2, but it was built for FIPS It leverages the organization’s experience with RKE and incorporates the streamlined core ideas and code of k3s. K3s is designed to What is the difference between K3s and RKE2? K3s is perfect for small applications because it’s a lightweight version of Kubernetes. Multus CNI is a CNI plugin that enables attaching multiple network interfaces to pods. The policy supporting this is a specialization of the container-selinux RKE2, aka RKE Government. Recently I was in discussions with a client that wants to use Kubernetes on their factory floor IIOT devices RKE2/K3s provisioning is built on top of the Cluster API (CAPI) upstream framework which often makes RKE2-provisioned clusters behave differently than RKE1-provisioned clusters.
