CRI-O
Lightweight Container Runtime for Kubernetes.

open source alternatives and stats
on LibHunt.
Lightweight
CRI-O is designed to be a minimal container runtime, which means it has a smaller footprint compared to other runtimes like Docker. This can result in lower memory and CPU usage, contributing to better performance and efficiency.
Kubernetes Integration
CRI-O is built specifically to integrate seamlessly with Kubernetes, implementing the Kubernetes Container Runtime Interface (CRI). This ensures better compatibility and more tailored features for Kubernetes environments.
Security
CRI-O is designed with security in mind and minimizes the attack surface by strictly following the principle of least privilege. It also supports compatibility with various security frameworks, such as SELinux and AppArmor.
Vendor Neutral
CRI-O is an open-source project under the Cloud Native Computing Foundation (CNCF), meaning it is vendor-neutral and has a diverse community contributing to its development. This decentralization helps in avoiding vendor lock-in.
Pluggable CNI
CRI-O supports Container Network Interface (CNI) plugins out of the box, providing flexibility in choosing different network providers based on specific use-case requirements.
CRI-O is considered a good choice for users who are running Kubernetes and prefer a streamlined, Kubernetes-native container runtime. Its compatibility with Kubernetes standards and its focus on using lightweight components make it a reliable option for a Kubernetes environment.
We have collected here some useful links to help you find out if CRI-O is good.
Check the traffic stats of CRI-O on SimilarWeb. The key metrics to look for are: monthly visits, average visit duration, pages per visit, and traffic by country. Moreoever, check the traffic sources. For example "Direct" traffic is a good sign.
Check the "Domain Rating" of CRI-O on Ahrefs. The domain rating is a measure of the strength of a website's backlink profile on a scale from 0 to 100. It shows the strength of CRI-O's backlink profile compared to the other websites. In most cases a domain rating of 60+ is considered good and 70+ is considered very good.
Check the "Domain Authority" of CRI-O on MOZ. A website's domain authority (DA) is a search engine ranking score that predicts how well a website will rank on search engine result pages (SERPs). It is based on a 100-point logarithmic scale, with higher scores corresponding to a greater likelihood of ranking. This is another useful metric to check if a website is good.

CRI-O provides a lightweight container runtime specifically designed for Kubernetes, implementing the Container Runtime Interface (CRI) with optimized performance. - Source: dev.to / over 1 year ago
Container engine security focuses on the underlying runtime system that manages and executes containers, such as Docker, containerd, or CRI-O. These container engines are responsible for interfacing with the operating system kernel to provide the isolated environments that containers run within. - Source: dev.to / almost 2 years ago
Minikube supports various container runtimes, including Docker, containerd, and CRI-O, allowing flexibility in the development environment. - Source: dev.to / almost 2 years ago
Kubernetes on the backend used to utilize docker for much of its container runtime solutions. One of the modular features of Kubernetes is the ability to utilize a Container Runtime Interface or CRI. The problem was that Docker didn't really meet the spec properly and they had to maintain a shim to translate properly. Instead users could utilize the popular containerd or cri-o runtimes. These follow the Open... - Source: dev.to / over 2 years ago
Multiple container runtimes are supported, like conatinerd, cri-o, or other CRI compliant runtimes. - Source: dev.to / over 2 years ago
Install container runtime on all nodes. We will use cri-o. - Source: dev.to / over 2 years ago
Container Runtime Interface (CRI) is one of the important parts of the Kubernetes cluster. It is a plugin interface allowing kubelet to use different container runtimes. And recently CRI-O container runtime has been announced as a CNCF Graduated project. I thought of writing a blog on CRI-O and how to set up a single-node Kubernetes cluster with Kubeadm and CRI-O. - Source: dev.to / almost 3 years ago
CRI-O: This is an open-source container runtime designed for use with Kubernetes. It is a lightweight and stable environment for containers. It also complies with the Kubernetes Container Runtime Interface (CRI), making it easy to integrate with Kubernetes. - Source: dev.to / about 3 years ago
Alternatives like Podman and CRI-O continue to gain traction and may replace Docker in various places. For example, Kubernetes used to use Docker, then moved to containerd, and now also support CRI-O. Generally speaking, the core features of "Docker" are such a commodity now that no one was the wiser when Kubernetes stopped using it. Source: over 3 years ago
The CRI-O container engine provides a stable, more secure, and performant platform for running Open Container Initiative (OCI) compatible runtimes. CRI-Os purpose is to be the container engine that implements the Kubernetes Container Runtime Interface (CRI) for OpenShift Container Platform and Kubernetes, replacing the Docker service.

The main difference is that Podman uses CRI-O while Finch uses containerd. At AWS we have chosen containerd for operation at scale, and run incredibly large numbers of containerd tasks for customers of AWS Fargate. So we build Finch to use containerd based on the trust we've built around seeing it function at scale inside AWS and for AWS customers. Source: over 3 years ago
So it's not for running production application containers. The libpod ecosystem component that does that is CRI-O (or Kubernetes for the orchestration. Source: almost 4 years ago

They're moving to OCI compatible runtimes but AFAIK docker actually has some issues getting users nowadays and I'm not aware of a Kubernetes distribution that uses Docker as the rutnime anymore. OpenShift for instance uses CRI-O which is a libpod implementation like podman but is a different stack. Source: about 4 years ago
Docker is one container environment, but it's not the only one, and you don't have to use Docker Desktop. It's ok and possibly even nice to have when you use Window, but containers are supported by CRI-O and containerd as run-times too. Kubernetes runs your containers too, so I fail to see any lock-in potential even. Source: over 4 years ago
Also make sure that you have cri-o, crictl, containernetworking-plugins, and buildah or docker installed. - Source: dev.to / about 5 years ago
Containerization, certainly, but you can run kubernetes just fine without Docker (I was under the impression most large-scale deployments now use Cri-O - https://cri-o.io/#what-is-cri-o). - Source: Hacker News / about 5 years ago
The docker utility isn't the only way to build and run containers. There's also cri-o, podman, and crun among others for running containers. For building there is podman again, Jib for Java applications, and bazel plus many others. The docker approach of using a client to connect to a daemon required to run as root has turned out to be slow and insecure. Source: about 5 years ago
Simply put, Docker is heavy. We get better performance with a lightweight container runtime like containerd or CRI-O. As a recent example, Google benchmarks have shown that containerd consumes less memory and CPU, and that pods start in less time than on Docker. - Source: dev.to / about 5 years ago
