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.

How to use Cloudflare 1.1.1.1 with Kubernetes DNS
I'd like to use Cloudflare's 1.1.1.1 and 1.0.0.1 nameservers in Kubernetes, alongside DNS over TLS. It looks like I can do it using core-dns. I need to setup the following somehow:
-
Dockerize Bind9 DNS with custom image
Shamless plug for CoreDNS. Much better DNS server than classic bind9. And of course there's already a nice container image for it.
-
Kubernetes traffic discovery
But another approach that could work in Kubernetes, because the DNS servers are within the cluster itself, would be to work directly with the DNS server pods. In most Kubernetes clusters, whether standalone or managed (GKE, AKS, EKS), the cluster DNS is either coredns or kube-dns. That was great to minimize how much configuration options we’d need to support. We realized we could edit the coredns or kube-dns configmap resources to enable their log option, which would make them log all the queries they handle. We’ll cover exactly how it’s done in more detail below.
-
Self hosted DNS server that responds to queries with data from web API?
CoreDNS has an ectd plugin, so your service could add entries to a database, which is used as record source. Not the same mechanism as you have described, but it will get the job done. Also this is what Kubetnetes does for incluster dns records.

Upgrade CoreDNS without downtime and without kubernetes
nevermind there's caddy builtin upgrade method https://github.com/coredns/coredns/issues/6034

Guide for using DNS with home lab servers?
Coredns can be spun up in a docker container, just starting to get into it myself

What would you rewrite in Golang?
CoreDNS is a pretty good DNS server.

How to securely reverse-proxy ASP.NET Core web apps
However, it's very unlikely that .NET developers will directly expose their Kestrel-based web apps to the internet. Typically, we use other popular web servers like Nginx, Traefik, and Caddy to act as a reverse-proxy in front of Kestrel for various reasons:

Deploying Web Apps with Caddy: A Beginner's Guide Caddy
Not as good though. Case in point: https://github.com/traefik/traefik/issues/5472#issuecomment-... (that's just from this morning)
I'm speak objectively here. Of course, any built-in auto HTTPS that works (more or less) is better than none. Traefik uses an ACME library that was originally written for Caddy. After the original author left that project, Traefik team started maintaining it. Caddy's users' requirements exceeded what the library was capable of, but unfortunately there was friction in getting it to achieve our requirements. So I ended up writing a new ACME client library in Go and, together with upgrades in CertMagic (Caddy's auto-TLS lib), Caddy has the more flexible, robust, and capable auto-HTTPS functionality.
That is to say, not all auto-HTTPS functionalities are the same.

Security Workshop Part 1 - Put up a gate
We'll use Traefik, an open source cloud native gateway that can plug into a Kubernetes cluster. It has the concept of "middleware" that can process API requests before passing them through to a backend. We can configuring a rate limit for all of our API endpoints by matching on the request path:

Install plugin in k8s cluster running in Kind
I did the same question here and here
- The Tailscale Universal Docker Mod
-
Set Default Config in traefik.toml and overwrite with specific container config
Sadly there is currently no way of doing so. https://github.com/traefik/traefik/issues/6999
- Istio moved to CNCF Graduation stage
-
Docker Services question
Traefik is another widely used system that has automatic configuration and offers support for more things like swarm/kubernetes/etc.

nginx alternatives
I have a webapp which I currently have deployed by running nginx in a container. Works as it should, however I am intersted in adding more observability to the webapp and found this reverse-proxy https://github.com/traefik/traefik which seems to expose some nice metrics which can be useful for observability.
