Replacements

Listings that take over the same core job as RKE2.

  • K3s

    Certified lightweight Kubernetes distribution packaged as a single binary.

    FreeOpen sourceLinuxSelf-hostedCommand line

    K3s is Rancher's lightweight single-binary Kubernetes for small ARM boards and low-memory hosts, with bundled Traefik and ServiceLB instead of a compliance-focused setup.

  • Kubernetes

    An open-source system for automating deployment, scaling and management of containerized applications across machines.

    FreeOpen sourceLinuxSelf-hostedCommand line

    An opinionated community Kubernetes distribution that bundles operators for a complete self-managed container platform.

    FreeOpen sourceLinuxSelf-hosted

    OKD is a heavier, opinionated OpenShift-style distribution with over 100 preinstalled operators and hardened defaults, needing significant infrastructure to run.

  • Kubespray

    Ansible playbooks and roles for deploying production-ready Kubernetes clusters on your own machines.

    FreeOpen sourceSelf-hostedCommand line

    Kubespray installs production Kubernetes on your own servers through Ansible inventories, requiring Ansible familiarity and offering no built-in CIS or FIPS focus.

  • k0s

    Zero-dependency Kubernetes distribution shipped as one self-contained binary.

    k0s is a zero-dependency single-binary Kubernetes distribution that installs the same way on any distribution, with fewer third-party guides and no stated compliance focus.

    Canonical's low-footprint Kubernetes for workstations, edge sites and CI.

    FreeOpen sourceWindowsmacOSLinuxSelf-hosted

    MicroK8s is Canonical's low-footprint Kubernetes with one-command add-ons and automatic high availability, installed through snap and without a compliance-focused design.

    An immutable, API-managed Linux operating system built only to run Kubernetes clusters.
