Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

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 Container Initiative or OCI's guidelines on container formats.

Multiple container runtimes are supported, like conatinerd, cri-o, or other CRI compliant runtimes.

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.

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.

How are they doing it?
With CRI-O I believe you can configure registry mirror locations…. Similar to this: https://github.com/cri-o/cri-o/issues/4941

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.

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. Source

A gopher’s journey to the center of container images
For the task of building the graph image, my first idea was to rely on buildah. In fact, our design was already heavily relying on containers/image for all things regarding copying images from one registry to the other, or from one registry to an archive. The obvious choice was to use the same suite of modules in order to keep dependencies to a minimum.

Podman Desktop for Java Development
I appreciate that podman can run daemonless, but I've gotten tired of waiting for them to implement heredoc support and have continued to use docker.

Podman v4.4, Buildah v1.29 released!
Last week, Buildah version 1.29 was also released. The prune command has been added to clean intermediate images as well as the build and mount cache. Support for the –group-add option to the from and build commands was added. One useful feature of this, it to use the –group-add keep-groups option, which allows rootless users to take advantage of their group access to file and devices mounted into the build containers. And the –cache-from and –cache-to options for the build command now allow for multiple sources. This can be used to improve the speed of builds, especially in CI/CD environments.

Rails on Docker · Fly
Unfortunately this syntax is not generally supported yet - it's only supported with the buildkit backend and only landed in the 1.3 "labs" release. It was moved to stable in early 2022 (see https://github.com/moby/buildkit/issues/2574), so that seems to be better, but I think may still require a syntax directive to enable.
Many other dockerfile build tools still don't support it, e.g. buildah (see https://github.com/containers/buildah/issues/3474)
Useful now if you have control over the environment your images are being built in, but I'm excited to the future where it's commonplace!
