What Were All Those Project Names on the KubeCon Europe 2023 Page?

Posted by on | Featured

When checking out this year’s KubeCon in Amsterdam, the following text snippet caught my attention:

“Join containerd, CoreDNS, Envoy, etcd, Fluentd, Harbor, Helm, Jaeger, Kubernetes, Linkerd, Open Policy Agent, Prometheus, Rook, TiKV, TUF, Vitess, Argo, Backstage, Buildpacks, Chaos Mesh, Cilium, CloudEvents, CNI, Contour, Cortex, CRI-O, Crossplane, CubeFS, dapr, Dragonfly, Emissary Ingress, Falco, Flagger, Flux, gRPC, Hubble, in-toto, KEDA, Keptn, Knativec, KubeEdge, KubeVirt, Kyverno, Litmus, Longhorn, NATS, Notary, OpenMetrics, OpenTelemetry, Operator Framework, SPIFFE, SPIRE, Tetragon, Thanos, and Volcano (…)”

A lot of project names! Some I did know, some which were completely new to me.

“What Is All This?”

It turns out, that those are CNCF Projects which are graduated or currently incubating.

The conference page got updated (2023-01-25) shortly after I stumbled upon it, and now contains the following text (emphasis mine):

Join our CNCF Graduated and Incubating Projects as the community gathers for five days to further the education and advancement of cloud native computing.

Instead of (‘opens python REPL and types furiously’) 55 different project names, the text now simply says “CNCF Graduated and Incubating Projects“. In case you didn’t click, it’s the official CNCF page, listing the biggest projects.

Note: I didn’t find this page back then, for better of worse. It’s a decent overview of course, with 1-4 (yes, I counted) words about each project!

While keeping up with Kubernetes was, and still is a full-time job, I like to make sure that I have at least an overview of all the parts that I don’t use day-to-day. It can’t hurt to spend some time and…

Dive Deeper

If you want to familiarize yourself with all of those projects, the CNCF page offers an interactive page to filter and browse all graduated projects and more if you adjust the filters.

There are also cool and large infographics, conveying an overview of those projects (and, once again, more) in a single image. Take this one for example.

If you want a mix of the infographic view and the filtered card, the main page is the place you should check out.

It’s fun to look over it, and try to spot some more obscure entries.

A much beloved project I spotted right away in that graphic is kube-rs for example – “it’s in “Orchestration & Management”, below Volcano.

Note: kube-rs is a Rust crate, which provides a way to communicate with the Kubernetes API. It’s at the core of all of our operators here at Stackable.

All of those ways to get more information are fine, but I like to compile info for later use. So I took some time to make my own humble overview in a familiar format.

An Overview Of All Mentioned Projects

I’m a firm believer in sharing intermediate work, and curiosity-driven research whenever possible.

While it’s an option to go to the official CNCF page and click each project to get what it’s about, I enjoy browsing around and only investigating what sparks my interest.

Here’s a compiled list of every project, with a small blurb of text from each page and a link to their site or GitHub page. The chosen text snippets are simply the first concise thing I spotted on those pages. I hope this list can invite you to browse and maybe click a link or two of your choice. All text blurbs are quoted and unchanged because there are 55 of them, holy moly.

That’s as Deep as We Will Go

Just listing out those 55 projects results in a pretty long list. And those entries are only the most visible and prominent ones.

The kube-rs project mentioned above for example, is not on that list. It is merely a CNCF Sandbox project, but it’s essential for working with k8s from Rust and at the core of day-to-day development here at Stackable. Imagine how much more activity happens around Kubernetes, which most people will not have the time or energy to explore.

I hope that this brief exploration has been useful to you, and that you have discovered one or two projects which you haven’t known about so far.
