KubeLetter #12

The week after KubeCon

It's the week after KubeCon NA. We had some great talks during KubeCon and a lot of information was shared. What were some of your KubeCon highlights?

In this edition of the KubeLetter, we've included a ton of news announced during KubeCon, blogs, some videos, CFPs, and more!

What's new with cloud-native

  • The Cloud Custodian project has added a Kubernetes admission controller for easy event-driven policy management within your cluster. The project also added support for running policies against HashiCorp Terraform.
  • A documentary film for Prometheus has been released which gives viewers an inside look at the journey from creation to mass adoption of one of the fastest-growing open source frameworks in the world.
  • Check out what's new with Open Cluster Management, where the project is headed, and how you can get involved in it.
  • LitmusChaos maintainers have announced the plan for the development of the next major release – Litmus 3.0. The project team is now encouraging reviews, contributions, and feedback around this Beta release
  • The OpenTelemetry demo is now generally available! With this demo, you’ll be able to quickly run a complete end-to-end distributed system instrumented with 100% OpenTelemetry Traces and Metrics.
  • Kyverno 1.8 has been released which is another huge leap forward not just in terms of features and functionality but of optimizations, performance, and other improvements required in strict or high-scale environments.
  • cert-manager has been accepted as a CNCF incubating project. cert-manager is a Kubernetes add-on to automate the management and issuance of TLS certificates from various issuing sources, for cloud-native Kubernetes or OpenShift environments.
  • The Monokle team has announced Monokle Cloud - a browser-based version of the popular Open Source Kubernetes Configuration management tool, Monokle Desktop.
  • The OpenSSL team announced critical security updates of versions above version 3.0. Few details of the vulnerability are currently available. Read this article by Armosec to know the potential consequences.
  • The Plural team has been hard at work over the past 2 months and has added some great features to the platform. Learn about them in this article.


  • Software supply chain attacks are one of the most critical risks threatening today’s software and have begun to collapse like a dark cloud over the software industry. In this article, learn how you can prove the Authenticity of OCI artifacts using Flux.
  • WASM is an emerging technology that has been getting a lot of popularity. The CNCF conducted a survey around Wasm micro survey. Check out what the survey revelaed.
  • Most modern applications use some sort of deployment strategy to ensure there are minimal downtimes when deploying a new version. Let's take a look at the blue-green deployment strategy and see how we can set it up.
  • Decentralization has proven to be an effective method of dealing with centralized bottlenecks. One approach to decentralizing control of data is using a data mesh. Let’s take a closer look at data mesh and go over its architecture to better understand its benefits.
  • Using Kubernetes has its own set of challenges and making sure everything works properly is essential. Let's look at how you can set up end-to-end tests for your Kubernetes clusters.

  • KubeSphere project gateways and Routes provide a method for aggregating Services, which allows you to expose multiple Services by using a single IP address in HTTP or HTTPS mode. Let's look at how you can use Kubesphere's gateway and routes.
  • Containers and Kubernetes are used to build, ship, and run cloud-native applications, which can be a complex process. Check out you can use K8S Lens IDE to make it easier to manage and deploy applications to your Kubernetes clusters.
  • Enterprises are constantly expanding their cloud footprints, and they can end up spending millions in cloud bills. Read this article by Finout to understand how FinOps can help you optimize your cloud spend.
  • Apart from having technical and code-related skills, developers also need some soft skills. This article by Zigi highlights some of the soft skills that every developer should have.
  • Graph databases are a relatively new and exciting type of NoSQL database that has been increasingly used for sophisticated applications over the past decade. Let's learn what graph databases are, and how they are beneficial.

CFPs open

Cloud-native tools highlight

  • Okteto: Okteto accelerates the development workflow of Kubernetes applications. You write your code locally and Okteto detects the changes and instantly updates your Kubernetes applications.
  • PowerfulSeal: PowerfulSeal injects failure into your Kubernetes clusters, so that you can detect problems as early as possible. It allows for writing scenarios describing complete chaos experiments.
  • Drone: Drone is a continuous delivery system built on container technology. Drone uses a simple YAML build file, to define and execute build pipelines inside Docker containers.
