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.

Using ECR as a mirror to transparently proxy docker-hub when rate limited
I’m trying out spegel, so far, it’s been great
-
Constantly re-pulling the same image(s)?
As other stated, check disk space, PullPolicy etc. However, local caching can be done using tools like Spegel that makes sure each node gets all images used in the cluster for faster restarts.
-
Pull through cache, like AWS just announced
I also recently found spegel, where each Cluster Node provides its images to the other nodes: https://github.com/XenitAB/spegel

Docker's deleting Open Source images and here's what you need to know
https://github.com/xenitAB/spegel
I have avoided a couple of incidents caused by images being removed or momentarily not reachable with it. It would at least mitigate any immediate issues caused by images being removed from Docker Hub.
- I created Spegel to enable nodes in a cluster to pull images from each other

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.

Container Engine: A runtime that executes and manages containers. Docker and containerd are popular container engines.

Complexity by Simplicity - A Deep Dive Into Kubernetes Components
Multiple container runtimes are supported, like conatinerd, cri-o, or other CRI compliant runtimes.

macOS Containers v0.0.1
This is a failed attempt to upstream part of containerd changes: https://github.com/containerd/containerd/pull/8789
Other part of containerd changes waits for gods-know-what: https://github.com/containerd/containerd/pull/9054
But I haven't gave up yet.
- Latest versions of Docker cause memory leak in MySQL 5.7

Kubernetes Setup With WSL Control Plane and Raspberry Pi Workers
containerd is required by kubernetes to handle containers on its behalf. A big thanks to the HostAfrica blog for the information on setting containerd up for debain. So the containerd install will need to happen on both the WSL2 instance and the Raspberry Pis. For WSL2 you can just install containerd directly:

Bingo of the Kubernetes problems I found myself debugging over the past weeks. AMA :p
The context deadline exceeded: unknown is also in containerd, and is a known problem.

Hi peeps, I am getting error installing docker. Now let me give you some context. I was trying to install docker on the google colab notebook. As google colab is ubuntu under the hood. So I just followed the docker linux terminal installation commands.

Docker Explained - Again
Docker Desktop adds a bunch of stuff to simplify local development and that’s why it has a larger memory footprint. You don’t use that when deploying but something like https://containerd.io/.
What are some alternatives?
Harbor - An open source trusted cloud native registry project that stores, signs, and scans content.
podman - Podman: A tool for managing OCI containers and pods.
crow-registry
cri-o - Open Container Initiative-based implementation of Kubernetes Container Runtime Interface
bottlerocket - An operating system designed for hosting containers
Moby - The Moby Project - a collaborative project for the container ecosystem to assemble container-based systems
ipcs - containerd meets ipfs to distribute content
podman-compose - a script to run docker-compose.yml using podman
lmctfy - lmctfy is the open source version of Google’s container stack, which provides Linux application containers.
colima - Container runtimes on macOS (and Linux) with minimal setup
distribution-spec - OCI Distribution Specification
sysbox - An open-source, next-generation "runc" that empowers rootless containers to run workloads such as Systemd, Docker, Kubernetes, just like VMs.
