So many conferences!

KubeLetter # 5

This the season of tech conferences. In this edition of Kubeletter, we've included 20+ open CFPs and a lot of news, blogs, tools, and videos. I hope you find it helpful.

What's new with cloud native

  • Monokle v 1.8.0 has been released. Learn what's new with Monokle
  • Testkube v.1.2 is out! Check out what's new with Testkube.
  • The CNCF is updating its Code of Conduct to be more transparent, include community voices, and more. Check out some of the upcoming changes.
  • Kubewarden has been added as a CNCF sandbox project. Kubewarden is a policy engine for Kubernetes.
  • The CNCF Security Technical Advisory Group has provided a lot of information to help organizations plan and design secure cloud-native systems. For this, the CNCF has introduced the cloud native security catalog
  • GitHub revealed that a bug allowed third-party applications to gain elevated access during the end of February. Check out how this happened

  • Kubescape has launched on Producthunt. Kubescape is a Kubernetes security compliance tool that provides a single pane of glass view across all your clusters and features such as image scanning, RBAC visualizers, and more.
  • Kubesphere v3.3.0 has released. Check out all the changes that come with it.
  • Volcano v1.6.0 is now available with new features such as elastic job management, dynamic scheduling and rescheduling based on actual resource utilization, and MPI job plugin.
  • LinkerD completed its annual security audit. Read about the issues they found.


  • Ghost Assets are assets in your code by not in the cloud, which can lead to cost and stability issues. The folks at Firefly are working to provide a fix for this issue.

  • You can use Kustomize to view and tweak your Kubernetes resources as needed. Now you can view Kustomize within Monokle saving you the time and headache it takes to identify and fix errors that come up.
  • Take a look at how you can integrate Traetest into your CI/CD pipeline using GitHub actions.
  • Kubernetes has a powerful ace up its sleeve, which we know as Operators. Learn what are operators and how you can use them
  • As with any developer tool, Docker has its fair share of complexities. Some of them are related to infrastructure and application monitoring. Thankfully, we have tools such as InfluxDB and Telegraf which help mitigate these complexities
  • OpenAPI has introduced a set of standardized specifications for REST APIs that allows producers and consumers of APIs to work together in designing an API before even writing a single line of code! In this tutorial, learn how you can leverage Kusk to rapidly prototype APIs

  • OpenTelemetry is an open-source observability framework for infrastructure instrumentation. Let's take a deep dive into how it works.
  • By default, nothing is protected in Kubernetes. Hence it is important to implement security layers manually. Now that the pod PSPs are deprecated, Armo has created a guide on how you can secure Kubernetes pods.
  • Kubernetes Admission Controller is an advanced plugin for gating and governing the configuration changes and workload deployment in a cluster. Here is the Definitive Guide to Kubernetes Admission controller by Armo.
  • Kubernetes costs can go beserk once the system requirements for your workloads increase. To keep the costs optimized, OpenCost has been introduced, which is a cost optimization standard created by folks at Kubecost.


  • Secrets are very important for authentication to a cluster, and if you lose the secret, or accidentally push it to your git repository, it will lead to trouble. You can however use Secrets with a External Secret Operator.
  • Does your system have too few resources needed to efficiently run your workloads? Well, now that won't matter. GitHub Codespaces give you instant access to a Cloud Development Environment, and it does not need a powerful laptop.
  • Setting up a good Observability in your clusters helps you manage it efficiently. Get an overview of Monitoring, Logging, and Alerting in Kubernetes and some tools you can use for it.
