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.

Migrating from dockershim to containerd
Installing crictl (https://github.com/kubernetes-sigs/cri-tools/blob/master/docs/crictl.md) was helpful, as well as journalctl -u containerd.
- kubectl get nodes -o wide shows containerd runtime, but sudo ctr containers list doesn't return any containers on host
-
Debugging containerd, A "new" container runtime means new debugging techniques are required
crictl: Uses the CRI interface to fetch data about containers, agnostic of CRIs. Maintained by Kubernetes at https://github.com/kubernetes-sigs/cri-tools
-
Quick question: Can you run crictl commands from within a running container?
FROM alpine:latest RUN wget -O - https://github.com/kubernetes-sigs/cri-tools/releases/download/v1.23.0/crictl-v1.23.0-linux-amd64.tar.gz | gunzip | tar xvf - && mv crictl /usr/bin

A Window into Docker, minikube, and containerd
We are in the endgame now. I promise. From the README, crictl provides a CLI for CRI-compatible container runtimes. The following snippet performs the following:
-
😎 Manage WebAssembly Apps in WasmEdge Using Docker Tools
Also make sure that you have cri-o, crictl, containernetworking-plugins, and buildah or docker installed.

i must be the only guy that understands certificates
cfssl is kinda outright better version of that.

SSL certificate problem: unhandled critical extension
The Cloudflare SSL tools at https://github.com/cloudflare/cfssl might help. Here's what it shows for one of the example Snake Oil certs:
-
Private CA management
I've used this in the past and it worked great. https://github.com/cloudflare/cfssl
- Linux Certificate Authority root stores have a too simple view of 'trust'
- Creating an internal Certificate Authority in 2022 that is accepted by modern web browsers.

How to create users in Kubernetes
The first step is to create the source key that represents our user. This key is created using a tool like openssl but another popular tool to use is cfssl, created by Cloudflare. Some folks think cfssl is easier to use, and it definitely looks easier to script. But for this example we will use openssl. You can also choose to create the key using a number of different algorithms. For this example we will use ED25519.

[Legal notice] IoT Core will be discontinued on Aug. 16, 2023
TLS/SSL worked well with client certificates generated by the CFSSL API.
