there seems to be a bug somewhere between #tomcat session replication (tribes), #k8s headless service and #istio ...
excluding inbound and outbound port 4000 seems to fix it.
my bet is that istio does not correctly updates it's knowledge about headless service ipv4 addresses if there are changes in the membership...

@SerhiyMakarenko #cilium. It's actually awesome. I’ve tried all the major ones over the years and I’m pretty happy with what cilium provides (it's like a good chunk of #istio service mesh but purely within your CNI)

Glad to see
@istiomesh aligning with Gateway API, replacing the native routing rules.
@boredabdel with #Istio updates at #KCDMunich

The convergence of ingress in the #kubernetes #cloudnative community is a great example of standardization I discussed with the CNCF'S CTO @Cra

#istio

Got me wondering why did I put a #caddy in front of #lemmy if I already have a whole #istio.

That match block makes me nervous, somehow.

Check out #DevOpsDaysBham2023 Jim Barton's interactive workshop, "Getting Started with Istio Ambient Mesh". Where he dives into Istio's latest innovation - Ambient Mesh, which simplifies service mesh usage by eliminating sidecars.

#eBPF carries a GPL copyleft license baggage from Linux, and this makes trouble to Apache2 #opensource, whether ones centered around eBPF like #cilium or an experimental side feature like in #Istio. The community and #CNCF are crunching it https://github.com/cncf/toc/pull/1000#issuecomment-1564662488

Curious on how your service mesh works?

Check out my deep dive into Istio, and learn about:

- Which APIs does Istio use?
- How to inspect the running Istio configuration using istioctl

RT by @linuxfoundation: Hope to see you at Open Source Summit North America 2023 next week in Vancouver. Excited to discuss and demo #Istio #AmbientMesh https://ossna2023.sched.com/event/fd99f239cf822b4e579c0ac44738acd3 #OSSUMMIT @sched

@jpetazzo Got it!

All your problems are related to the implementation of the `terraform` module IIUC, no?

For the #Istio workshop (same strategy as you), we used `tf` and had some problems too. I tried the same thing with #ConfigConnector, it was better (fully declarative) but too young when we needed it.

So, I understand more your feedback now and it a shame a good product like this can be perceived bad because of the intermediate tooling.

I'll try to share that internally 😇

Is #Istio the perfect foundation for running your #microservices❓

Watch this #InfoQ video by Eitan Suez to understand how Istio functions, its design & its architecture, in order to critically evaluate how astute it is as a foundation for running microservices or distributed applications in general: https://bit.ly/3UPVZPC

#transcript & Q&A included

#SoftwareArchitecture

Istio ambient mesh introduces a new sidecar-less data plane option for #Istio #ServiceMesh.

This #InfoQ article by Lin Sun discusses the advantages of that approach and the work that went into making it a reality: http://bit.ly/3FpfqIP

Looks like I'm going to #voxxeddaysbucharest in a few weeks😀

@natalevinto and I will be doing a talk/demo about Progressive Delivery with #ArgoCD, #Istio, #Prometheus and #ArgoRollouts 🚀🚀🚀

#Ansible and #Kubernetes was the topic today. I cover using #AWX with some playbooks to respin on-prem #k3s multi-node cluster without #traefik. We will create #Istio and #CertManager playbooks then tackle using #AzureDNS in a new #ClusterIssuer. See the video at the end of a full end-to-end demo. https://freshbrewed.science/2023/02/24/k3s-ansible-azuredns.html
