#k3d — Public Fediverse posts

#k3s or #k3d? Is there even a difference - and also, what are they useful for? Is it really only good for a quick 'throw-away' #kubernetes cluster for testing, or something? coming from something like #rke2 (which i know is prolly not a good comparison, but still curious how they could be useful to me)

As a longtime fan of local #k8s clusters for fast feedback (especially #k3d),I've just faced my first real challenge: deploying LDAP 😅
(caused by #apparmor and nested containerization)

A short story for the seasoned container engineer 👇️

Having fun with #Nix, #k3d and #CERN's QuarkDB: Run it on a (local) Kubernetes cluster! https://codeberg.org/carletes/quarkdb-container-image

Hello #Mastodon! And hello everybody on it, my name is John Kaskets and I'm happy to be of service! Feel free to take a look at my recent project released into the wild! The K3D Catapult Dice Tower 3D modeled and 3D printed by me and available by direct purchase in custom color choices or by download ONLY on Cults3D!!! #dnd #dicetower #K3D #K3Ddesignandfunction #dungeonsanddragons #Warhammer40k

I'm unable to create a local #K3s instance with #K3d on my #ArchLinux with Rootless #Podman - Does anyone have a hint how I could make that work? https://github.com/k3d-io/k3d/issues/1429

With Kind I would be able to spin up a local Kubernetes instance and Rootless Podman, but without support for ephemeral storage, which breaks countless workloads.

https://dev.to/iamunnip/building-a-local-kubernetes-cluster-using-k3d-2p3d - on #Linux and want a simple #Kubernetes cluster? Getting started with #k3d, a nice CLI around #k3s. Nice tutorial https://github.com/iamunnip.

Me before today: #k3d and #k3s are basically the same.

Today: let's add an external node to this on demand so I can do big things!

Me today: dang, k3s and k3d are different in important ways 😥
#kubernetes

I just published a post about using #K3D to create lightweight local #kubernetes clusters. Check it out:

#selfhosted #linux #devops

Been playing with #k3d and #tilt recently. K3d deploys lightweight #kubernetes cluster on top of #docker with local storage, load balancing, and an ingress controller in under 2 minutes. Pretty freaking awesome.

And Tilt is basically a local #CI loop which can rebuild and deploy your containers and helm charts. For the project I was playing with, it would deploy rebuild and deploy my changes in about 15s.

@geekgonecrazy @jorge I have gotten #k3d to work in #Kinoite with podman-docker.

Last but not least, if you need a path-local PersistentVolumeClaim across multiple pods (such as for #Mastodon) in #k3d that is read/write for all, then those pods all need to live on the same node as per k8s specs.

I couldn't find this documented anywhere, but if you use nodeName (the simplest solution) to lock the pods to a node, then this will break the PVC! You must use nodeAffinity instead.

On #k3d and #k3s

Make sure you have your cluster setup right with k3d. Changing things is nigh impossible without recreating the entire cluster!

If you have services running in docker you want to expose to k3s (such as your main PostgreSQL), connect that container to k3d's docker network, then add that IP to k3d's CoreDNS ConfigMap NodeHost section. I've not found any other reliable way to do this.

Docker and ufw still do not play nicely together without ufw-docker. nmap every change!

✋🏻 @dhoppe ✋🏻thank you for reaching out with #k3s and #k3d I had a go with the first and will definitely check the second.

@giuseppe I was never a big fan of Minikube. Depending on your requirements, you might want to look into K3s / K3d.

Ever wondered what we would have if we didn't have #Blender?
The answer is a scattered mess of FLOSS projects, each tailored for a specific task, not the least of which being #K3D, the only one that does 3D animation, although I have yet to see a single piece of art or animation made with it.
I can't predict alternate realities and of course more effort and developers would've gone into these other projects but man, would things be different without Ton Roosendaal. 🧡 💙 🧡
#b3d

Stumbled over #k3d today. Pretty handy to spin-up a #kubernetes for CI environments like #droneci or #woodpecker to run automated deployment tests #devops #sysadmin

I also got a #Kubernetes cluster going with #rancher #k3d as well and it was admittedly a little easier since it could grok podman's Docker emulation.
