RKE2 vs MicroK8s
Both are alternatives to Red Hat OpenShift. Here's how they stack up — verified facts, no spin.
RKE2
The hardened one — FIPS 140-2 and CIS defaults out of the box.
SUSE/Rancher's security-focused distribution: a more traditional Kubernetes footprint than k3s with FIPS 140-2 compliance and CIS-hardened defaults from the first boot. The natural step up when compliance paperwork enters the room and the natural OpenShift exit for government-adjacent shops.
MicroK8s
Canonical's batteries-included Kubernetes — one snap install.
Ubuntu's answer: a snap-installed Kubernetes with add-ons (DNS, ingress, observability, GPU) enabled by single commands. Great developer-to-small-production path, with Ubuntu Pro support available if you want a vendor. The snap packaging is beloved and resented in roughly equal measure.
Side by side
| RKE2 | MicroK8s | |
|---|---|---|
| Sovereignty Score | 92 | 88 |
| Open source | Yes | Yes |
| Self-hostable | Yes | Yes |

RKE2 edges it on the Sovereignty Score, but the right pick depends on the trade-offs below.
RKE2
Strengths
- +FIPS 140-2 compliant out of the box
- +CIS-hardened defaults
- +Shares tooling and lineage with k3s — easy to adopt both
Trade-offs
- −Heavier footprint than k3s
- −Commercial support pricing isn't public
MicroK8s
Strengths
- +One-command install and add-on system
- +Smooth developer-to-production path on Ubuntu
- +Vendor support available from Canonical
Trade-offs
- −Snap dependency polarizes operators
- −Most at home in Ubuntu-centric environments
