Was Service Catalog Redundant After All?

Kubernetes logo

tl;dr - Service Catalog might ahve been a redundant concept after all… Was it just the hobby-horse of large integration-happy stakeholders?

I’ve always been sort of confused by the concept of the Service Catalog – so much so I’ve posted about it before to get a feel for public consensus.

For those who don’t know what service catalog was – here’s a great post from WeaveWorks on it

People have put hard work into supporting this concept, chairing the SIG, and pushing it forward, but I have to say that I don’t think I ever squared why it was necessary in a world with operators present.

Ever since I first saw it I thought it was a bad idea/duplication of the operator pattern in general. I must have been feeling particularly conspiratorial those days because it seemed like an enterprise roadmap “plant”. Nevertheless, smart people worked on it, and I can’t help but think that it was always a bit of an over-complicated and over-engineered. This is the exact kind of thing that sounds good in a conference room – I can just HEAR it being pitched.

OK but is it actually gone?

Yeah I guess I should have mentioned that earlier. What spawned this whole post was reading through changelogs and release blogs and wondering “whatever happened to Service Catalog?” I was unable to find the usual docs page – they disappeared suddenly from the with no mention in the Changelogs/releases as far as I saw:

The site is gone

One of the first things that tipped me off was which was linked in some places being no longer protected by HTTPS (!).

Looks like Microsoft also likes to re-use certificates for lots of dynamic properties:

Websites prove their identity via certificates. Firefox Developer Edition does not trust this site because it uses a certificate that is not valid for The certificate is only valid for the following names: *, *, *, *, *, *,, *, *, *, *, *, *, *, *, *, *, *, *, *, *, *,,,,,,,,,,,,,,, *,,,,,,, *, *,,,,,,, *, *, *, *, *, *,, *, *,,, *,,, *, *,,,,,, *,,,,,,, *, *, *, *,, *,,, *, *,,,

I don’t know if that’s best practice but that’s neither here nor there I guess, but I sure was surprised to see this many very unrelated domains under one cert!

The repo is retired

The Service Catalog (service-catalog) repo has moved to kubernetes-retired.

The SIG Service Catalog Google Group has gone dark-ish

And this is the sadder part, sometimes you forget the people who put in hard work and drove consensus around an idea – I found the dissolution message regarding SIG Service Catalog by Bob Illen, and it looks like there’s been no activity in the Google Group since April 2022.

Digging a bit more, it looks like this became a somewhat sure thing when Jonathan ran out of time to devote to the project in November 2021.


Well, I can’t say I’m sad to see it go, but I do hope the people who invested time and effort into SIG Serivce Catalog are finding their needs met (with operators, I assume!) and are doing well these days.

I can’t help feeling like I just missed this being announced somewhere (other than the Google Group), but I guess the internet will tell me, wth great fury, if I have.

“All aboard the operator hype train” to the rest of the corporate Kubernetes landscape!
