#Knative has graduated!

https://www.cncf.io/announcements/2025/10/08/cloud-native-computing-foundation-announces-knatives-graduation/

The problem of having knowledge is knowing when to use. 😅

Case in point, right now thinking either #systemd activation socket or #knative on #kubernetes for home stuff. 🫠 The goal here is HTTP requests turn on service, does some stuff, and gracefully drains down on idle.

Well as of today I’m officially laid off...

If anyone is looking for a Senior Platform Engineer with a lot of #Kubernetes, #Crossplane, #Terraform, and #Knative, please send them my way! 💜

Data center emissions are surging. Every millisecond counts. Can native #Java with #Knative tilt the balance? Marius Stein & Vishal Shanbhag explore how new builds bring old stacks into a greener future.

#GraalVM #Cloud #JVM @graalvm

Somehow I can't get #knative to work properly with contour ontop of #cilium as cni.
Always routes itself into some kind of loop holes.

Currently trying to get #knative in my homelab going. Stumbling into issues with getting kourier running. Somehow the envoy keep crashing due to now reachable upstreams. Using the knative operator for getting the knative-serving up an running. Does someone else ran into the same issue?

config-wise its pretty easy currently
```
apiVersion: operator.knative.dev/v1beta1
kind: KnativeServing
metadata:
name: knative-serving
spec:
ingress:
kourier:
enabled: true
service-type: "ClusterIP"
```

An interesting talk here at #KubeCon by @terrytangyuan from #RedHat and Adam Tetelman from #NVIDIA on the many pitfalls of using LLMs in production.

#KServe and #Knative come to the rescue of many Day 2 problems, but there's still a lot to do.

And, as Adam Teleman said so well, this year's KubeCon could easily be called RAGCon, given how many talks there are about #RAG 😀

#KubeCon24 #AI #LLM

Dávid Šimanský talks about an event-driven approach in moderating offensive words in discussions and comments using #Kafka and #Knative.

I use Kafka, but the cloud world is still unexplored for me in terms of technology.

#DevConf_CZ

What a way to finish my week! I just finished talking with my friends from @[email protected] @[email protected] and @[email protected] about all things #kubernetes #knative #dapr #tekton #kcp #kubebind and what is coming in 2023!! 🤯🤯

Playing around with #knative ... Added an helloworld app using #axum instead of the default #actix ... https://github.com/timvw/knative-rust-axum

If you weren't able to join our session about power monitoring Serverless apps with #Kepler and #Knative at #KubeCon #CloudNativeCon, we're happy to report the recording is already available! 😀

From the ADMIN Update newsletter: @madkiss shows you how to transfer serverless workloads to Kubernetes with Knative https://www.admin-magazine.com/Archive/2023/78/Native-serverless-computing-in-Kubernetes #Knative #Kubernetes #serverless #application #PaaS #FaaS #K8s #containers #CNCF

#CloudEvents open specification has reached graduation at the #CNCF 👏
The spec has been adopted by #Adobe I/O Events, #AlibabaCloud EventBridge, #Azure Event Grid, #GoogleCloud Eventarc, #IBMCloud Code Engine, the European Commission and more.
And of course it's been adopted by CNCF projects, such as #Argo, #Falco, #Harbor, and #Knative.
The beauty is that it fits in nicely with existing eventing infrastructure, so I expect more adopters to follow

@samir what's the use case? If low startup latency on #kubernetes is required then I'm thinking you would might want to look into #FaaS options like #knative, where you can keep a warm worker pod ready and preemptively scale up more pods based on demand.

Yesterday, we released vscode-openshift 1.8.0. The main feature is creating #Knative serverless functions from templates in custom template repositories. We also improved the documentation and removed many unused dependencies. See the full changelog here: https://github.com/redhat-developer/vscode-openshift-tools/blob/main/CHANGELOG.md#180-september-14-2023

@jonskeet didn't know you are working for #CloudEvents but you answered my question about #knative functions in 5 minutes.
Slightly off topic, so not about functions but just about knative eventing and serving:
what about #dotnet (c#) cold startup times for serverless pods scaling to zero?
Is that a resolved issue nowadays?

Played with #Knative on #Kubernetes today, it's pretty nifty

I used `oha` to stress-test a basic health-check service, and it's cool that #KnativeServing can scale from 0 service pods, to 1 pod, and eventually up to 10 pods, all without dropping any requests (the requests are queued if there aren't enough service pods)

It's like having my very own AWS Lambda at home (and honestly easier for me to use than AWS Lambda)

These are the results for running `oha -c 1000 -z 30sec` against my cluster which has 3x Raspberry Pi 4B nodes (all nodes are control-plane nodes but with pod-scheduling enabled):
