• The Road To Kubernetes: How Older Technologies Add Up

  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 / 3 months ago

  Multiple container runtimes are supported, like conatinerd, cri-o, or other CRI compliant runtimes. - Source: dev.to / 5 months ago

  Install container runtime on all nodes. We will use cri-o. - Source: dev.to / 5 months ago

• Creating Kubernetes Cluster With CRI-O

  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 / 9 months ago

• Understanding Docker Architecture: A Beginner's Guide to How Docker Works

  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 / 11 months ago

• Docker is deleting Open Source organisations - what you need to know

  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: about 1 year ago

• Container Deep Dive 2: Container Engines

  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.

• Introducing Finch: An Open Source Client for Container Development

  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 1 year 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: over 1 year ago

• Containers.

  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: almost 2 years ago

• In an on-premise, non containerized context, what is the best way to deploy a Node.js app (artifact) to a server?

  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 2 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 / almost 3 years ago

• Is Docker Dead in the Water?

  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: almost 3 years ago

• Kubernetes vs Docker: Understanding Containers in 2021

  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 3 years ago
