Below is a non-exhaustive list of CRI-O adopters in production environments:
- Red Hat's Openshift Container Platform uses CRI-O as the only supported CRI implementation starting with the release of OpenShift 4. CRI-O was chosen because it provides a lean, stable, simple and complete container runtime that moves in lock-step with Kubernetes, while also simplifying the support and configuration of clusters.
- Oracle Linux Cloud Native Environment has used CRI-O since release due to its tight focus on the Kubernetes CRI and its ability to manage both the runc and Kata Containers runtime engines.
- SUSE CaaS Platform uses CRI-O since version 3. It has been initially supported as technology preview in version 3 and moved to the default Kubernetes container runtime since version 4 as a replacement for Docker.
- openSUSE Kubic is a Certified Kubernetes distribution based on openSUSE MicroOS. It uses CRI-O as a supported container runtime for Kubernetes.
- Digital Science is using CRI-O as the runtime in data processing clusters behind Dimensions due to it being just enough runtime for Kubernetes, and the flexibility to use more than runc.
- HERE Technologies uses CRI-O as the runtime for our home grown Kubernetes clusters. We like that it is purpose built for Kubernetes and has a strong community backing it.
- Particule uses CRI-O as part of our bare metal solution Symplegma to deploy Kubernetes with Ansible. We aim to be as vanilla and up to date with community standards as possible.
