k3s vs Rancher: What are the differences?

k3s: Lightweight Kubernetes. 5 less than k8s (by Rancher Labs). Certified Kubernetes distribution designed for production workloads in unattended, resource-constrained, remote locations or inside IoT appliances. Supports something as small as a Raspberry Pi or as large as an AWS a1.4xlarge 32GiB server; Rancher: Open Source Platform for Running a Private Container Service. Rancher is an open source container management platform that includes full distributions of Kubernetes, Apache Mesos and Docker Swarm, and makes it simple to operate container clusters on any cloud or infrastructure platform.

k3s and Rancher can be primarily classified as "Container" tools.

Some of the features offered by k3s are:

  • ARM64 and ARMv7 support
  • Simplified installation
  • SQLite3 support

On the other hand, Rancher provides the following key features:

  • Manage Hosts, Deploy Containers, Monitor Resources
  • User Management & Collaboration
  • Native Docker APIs & Tools

k3s and Rancher are both open source tools. It seems that Rancher with 11.9K GitHub stars and 1.34K forks on GitHub has more adoption than k3s with 7.81K GitHub stars and 483 GitHub forks.

    What are some alternatives to k3s and Rancher?
    Kind
    It is a tool for running local Kubernetes clusters using Docker container “nodes”. It was primarily designed for testing Kubernetes itself, but may be used for local development or CI.
    Docker Swarm
    Swarm serves the standard Docker API, so any tool which already communicates with a Docker daemon can use Swarm to transparently scale to multiple hosts: Dokku, Compose, Krane, Deis, DockerUI, Shipyard, Drone, Jenkins... and, of course, the Docker client itself.
    Docker
    The Docker Platform is the industry-leading container platform for continuous, high-velocity innovation, enabling organizations to seamlessly build and share any application — from legacy to what comes next — and securely run them anywhere
    Kubernetes
    Kubernetes is an open source orchestration system for Docker containers. It handles scheduling onto nodes in a compute cluster and actively manages workloads to ensure that their state matches the users declared intentions.
    Docker Compose
    With Compose, you define a multi-container application in a single file, then spin your application up in a single command which does everything that needs to be done to get it running.
