Как работать с CAPY

Привет, Хабр! Я Данил Трещев, работаю в T-Банке в команде Spirit Compute, которая отвечает за runtime-инфраструктуру. Сегодня я хочу рассказать, как работать с Cluster API Provider Yandex (CAPY). Мы разработали собственное решение, которое позволяет разворачивать k8s-кластеры в инфраструктуре Yandex Cloud. Разберем, как развернуть Management Cluster и Workload Cluster с помощью инструментов управления кластерами. Материал подходит для обучения и тестирования. Итоговое окружение не будет готово к продакшену — для этого понадобятся дополнительные настройки безопасности и отказоустойчивости. Добро пожаловать под кат все, кому интересно познакомиться с темой!

The Cluster API Visualizer is an open-source tool designed to simplify the management and understanding of multicluster Kubernetes environments using CAPI. It offers a comprehensive overview of multicluster architectures, visualizing all Cluster API custom resources for each cluster and providing quick access to their specifications and statuses. This makes it easier for both new and experienced users to navigate complex cluster setups: https://github.com/Jont828/cluster-api-visualizer #clusterapi #OpenSourceSunday

We here at Sidero Labs are not capable of time travel.

If we were, we would send you back in time to KubeCon so you could watch Clément Nussbaumer tell his story of migrating 25 clusters in an air-gapped environment.

But if you have a few minutes, you can watch his talk on YouTube. Check it out for a live migration demo and a look at how Post Finance manages its fleet. It's a great watch. https://www.youtube.com/watch?v=uQ_WN1kuDo0

with the recent demo and alpha release of the karpenter provider cluster api, i've taken the opportunity to write a brief retrospective on the engineering process so far. hopefully it will be helpful to others who are investigating karpenter integrations.

#kubernetes #Karpenter #ClusterAPI

quick follow up, i have created a pull request to migrate this repo from my personal github to the kubernetes-sigs org. happy for any comments and feedback on the pr.

we will discuss adopting the project into kubernetes-sigs at the sig cluster lifecycle meeting on 20 august. if there are no objections or corrections needed, we will plan to migrate the repo after that meeting.

#Karpenter #ClusterAPI #kubernetes

excited to share the first demo of the proof-of-concept #Karpenter #ClusterAPI provider for #Kubernetes. there is still a ton to do, but the next steps will involve contributing the repo to the kubernetes-sigs org on github.

video is up, if you the missed the meeting yesterday you can now watch my screen sharing fail in glorious recorded fashion, lol

shoutout to Fabrizio for really saving my guanciale XD

#kubernetes #clusterapi #karpenter

had a great discussion at the cluster-api office hours today. here is the link to the slides i presented, will post a video link when it's posted.

I feel dirty with the amount of yaml and crd hacks I had to do today to restore a working system after a failed upgrade. At least I know enough to actually fix stuff but *ugh* #kubernetes #clusterapi

going to give an architecture preview of the karpenter cluster-api provider proof-of-concept tomorrow at the cluster api office hours. in preparation for that i am sharing the code i have been hacking on so far.

it's nowhere near ready for use as i am still implementing the provider interfaces, but in the spirit of open i feel better having this in the public.

Looking for SREs for one of our Cluster API teams: https://giant-swarm.jobs.personio.de/job/180887?display=en

#giantswarm #sre #clusterapi #kubernetes

After 10 years of wrangling Kubernetes in the trenches, we've supercharged our platform by going all-in on #ClusterAPI. So I'm happy to announce our third generation platform right on time for #kubecon.

I dislike how so many tools add magic without a good opt-out mechanism or even an indication where the magic is added. Ie. using clusterapi and capt (tinkerbell) your control plane nodes get the label "node.kubernetes.io/exclude-from-external-load-balancers", but I have no idea which component adds the label nor how to disable it, as I don't want it for my particular setup.

@tormath1 And we're live! The room is bursting!

#CAPI #ClusterAPI #kubernetes #Flatcar

Deloying #Kubernetes ... from Kubernetes?

Check out #Flatcar maintainer @tormath1 's #ClusterAPI talk in the virtualization and cloud infrastructure Devroom at #fosdem2024 , 2:30pm CET: https://fosdem.org/2024/schedule/event/fosdem-2024-2943-deploy-kubernetes-from-kubernetes-an-overview-of-cluster-api/

Live stream will be available from that page for remote participants.

The cluster-api experiment was a bust. After building the nodes with Terraform, and getting the management cluster online, the BYOH nodes failed to join with an error I can't find anywhere other than the source. Too alpha, will try again in a year...

Would be nice if CAPI had a Proxmox provider but Proxmox tooling support is.... Bad.

#clusterapi #kuberbetes #proxmox #terraform

Great to see the @OpenStack community embracing Flatcar and #ClusterAPI... in addition to the existing OpenStack CAPI provider, there's now a Magnum provider for all your container workloads. Nice! 👍

Is there a Matrix channel to ask questions like: "Is it possible to setup a #ClusterAPI #k8s cluster in a airgabed environment?"

My mood this morning trying to get some flaky CI tests to pass and a flaky CD system to actually deploy... I can't wait until we finish the rewrite and migration to #ArgoCD and #ClusterAPI

hey #kubernetes massive, hot off the virtual presses, we've just released version 0.6.0 of the kubemark provider for #clusterapi , check it out!
