KubeLetter #14

Hey everyone, welcome to the first Kubeletter of 2023. How was your 2022? We hope it was full of learning and achievements. If not, make 2023 your year.

In this edition, we've included some exciting news from the world of cloud-native, along with tons of great resources and more importantly, lots of CFPs.

What's new with cloud-native

  • The software supply chain security has a lot of moving parts and it can become difficult to stay up to date with them. Join the Software Supply Chain Security community to stay up to date with all things SSCS.

  • Argo has become a CNCF graduated project. The Argo Project enables organizations to declaratively deploy and run cloud-native applications and workflows on Kubernetes using GitOps.

  • Flux has become a CNCF graduated project. Flux is multitenant, multicluster, and multi-cloud, and natively supports Kustomize, Helm, and HashiCorp Vault

  • Istio 1.16 is out and comes with a ton of improvements including HTTP-Based Overlay Network Environment support in sidecars and ingress and much more.

  • The KubeCon event strategy has received some major updates. Read about all the new changes to the structure of KubeCon.

  • The CNCF has made some changes to the health and safety policies for in-person events. Check out the changes.

  • The LFX mentees of the fall term have graduated. Check out all the successful mentees and what they have achieved through the LFX mentorship program.


  • Score envisions a developer and workload-centric approach to improving developer productivity and experience. In this article, let's take a deeper look at the “why” and see this as a starting point to discuss and shape a product vision we can work towards as a community.

  • GitHub Actions has made it easier than ever to build a secure CI/CD pipeline for your GitHub projects. Now, Armosec can integrate with GitHub actions, allowing you to scan your containers before deploying.

  • Generating and storing logs from Kubernetes clusters get very expensive. In this blog from Finout, let's see how you can optimize your log costs and which logs you actually need to keep an eye on.

  • When it comes to designing core components of a software architecture one of the early decisions that need to be made is where to store the state of the application. In this article, let's learn about stateful authorization.

  • Observability is key when running cloud‑native apps. In cloud-native, app functionality emerges from the interaction between numerous microservices running in multiple locations. Let's learn how open telemetry helps with observability, and how it is taking cloud-native to new heights.

  • Fluentd is an open-source data collector capable of retrieving and receiving event data from several sources and then filtering, buffering, and routing data to different compatible destinations. Let's learn how you can use fluentd for data collection.

  • For almost as long as Replit has been around, people in the community have been asking for a way to create and share their very own Custom Themes! Well, now you can. Check out the new custom themes introduced by Replit.


  • Understanding Kubernetes core components as well as those hidden in the background gives you a much stronger knowledge of Kubernetes and will also make you more much effective with its use! In this video, let's build our own Kubernetes cluster from scratch and understand its individual components of it.

  • What exactly is the CNCF? How can you get involved in it? In this video, Bart Farrell and Kaiwalya Koparkar will talk about their journey through the CNCF, and how one can get involved in it.

  • Monitoring is an essential part of making sure self-hosted services are up and running and performance is as expected. In this video, let's learn about Checkmk Raw edition which provides a free and open source server & application monitor you can spin up in seconds in a Docker container.

  • Authelia is an open-source Single Sign On and 2FA companion for reverse proxies. It helps you secure your endpoints with single-factor and 2-factor auth. It works with Nginx, traefik, and HA proxy. Let's learn to configure Authelia with Portainer and Traefik and have 2 Factor up and running with brute force protection!

  • Networking in Kubernetes has multiple aspects which can get confusing at times. In this tutorial, let's learn all about networking in Kubernetes.

  • What is the motivation behind building a Prometheus runbook and why should you care? In this talk, Natan will talk about the motivation and challenges of building a production-ready runbook automation system along with a hands-on demo.


  • Civo Navigate is an in-person tech event packed with talks and workshops focused on navigating and succeeding within the cloud native landscape. Register and attend to get some high-quality talks, workshops, and a chance to meet Steve Wozniak.

  • Open Source Summit is the premier event for open source developers, technologists, and community leaders to collaborate, share information, solve problems, and gain knowledge, furthering open source innovation and ensuring a sustainable open source ecosystem.

  • The schedule for CloudNativeSecurityCon 2023 is now avaliable! Register for the event and add your favorite talks to your calendar.

  • Battlesnake Campus Tour is a hackathon sponsorship with a twist. Receive up to USD 2000 in funding, prizes, tools, mentors, and more for hosting a battlesnake hackathon at your college or university.

CFPs open

Cloud-native tools highlight

  • Tracetest works with your current OpenTelemetry-based system. It has native integrations with Jaeger, Grafana Tempo, Open search, SignalFX — and more integrations will be added. It also supports any system using the OpenTelemetry Collector.

  • Kubeshark provides Deep visibility and monitoring of all API traffic and payloads going in, out, and across containers and pods inside a Kubernetes cluster.

  • OpenCost, a CNCF Sandbox Project, is bringing Kubernetes and cloud cost monitoring to everyone as an open source standard and project

  • Octant is a tool for developers to understand how applications run on a Kubernetes cluster. It aims to be part of the developer's toolkit for gaining insight and approaching the complexity found in Kubernetes.

  • Kubetail is a bash script that enables you to aggregate (tail/follow) logs from multiple pods into one stream. This is the same as running "kubectl logs -f " but for multiple pods.

  • Kiali is a management console for Istio service mesh. Kiali can be quickly installed as an Istio add-on or trusted as a part of your production environment.
