    Pierre: The first tool I recommend is K9s. It's not just a time-saver but a productivity booster. With its intuitive interface, you can speed up all the usual kubectl commands, access logs, edit resources and configurations, and more. It's like having a personal assistant for your cluster management tasks.

  • VictoriaMetrics

    VictoriaMetrics: fast, cost-effective monitoring solution and time series database

    • Project mention: OpenTelemetry Is Too Complicated | news.ycombinator.com | 2024-04-03

    VictoriaMetrics CTO here.

    The referred library is the official OpenTelemetry package for reading metrics in Go language [1] - more details are available at [2].

    Note that we at VictoriaMetrics like the idea of unified observability standard like OpenTelemetry. The issue is in the current otel implementation. It is too bloated and very inefficient. This contradicts to our experience with observability cases, which need very optimized format for metrics' transfer in order to reduce costs on CPU and network traffic needed to transfer and process these metrics.

    VictoriaMetrics continues investing in OpenTelemetry by providing integration docs [3] and improving the existing functionality for otel metrics' ingestion [4].

  • Netmaker

    Netmaker makes networks with WireGuard. Netmaker automates fast, secure, and distributed virtual networks.

    • Project mention: Netmaker: An open source WireGuard VPN | news.ycombinator.com | 2024-02-23

  • ddosify

    Effortless Kubernetes Monitoring and Performance Testing. Available on CLI, Self-Hosted, and Cloud

    • Project mention: 5 Awesome Go Projects To Know Before You Die | /r/golang | 2023-05-05

    DDosify: https://github.com/ddosify/ddosify

  • Reloader

    A Kubernetes controller to watch changes in ConfigMap and Secrets and do rolling upgrades on Pods with their associated Deployment, StatefulSet, DaemonSet and DeploymentConfig โ€“ [โœฉStar] if you're using it!

    • Project mention: How are people managing env vars for Static Applications? | /r/devops | 2023-12-09

    You can combine this approach with something like https://github.com/stakater/Reloader to automatically restart pods when a certain secret value changes. So if your static code needs to be rebuilt when certain values change, you can use an init container to run the build on startup.

  • k3sup

    bootstrap K3s over SSH in < 60s ๐Ÿš€

    • Project mention: K3s โ€“ Lightweight Kubernetes | news.ycombinator.com | 2023-10-11

  • vcluster

    vCluster - Create fully functional virtual Kubernetes clusters - Each vcluster runs inside a namespace of the underlying k8s cluster. It's cheaper than creating separate full-blown clusters and it offers better multi-tenancy and isolation than regular namespaces.

    • Project mention: Amazon EC2 Enhances Defense in Depth with Default IMDSv2 | news.ycombinator.com | 2023-11-27

    Kubernetes? You mean the container orchestration system where they forgot to add Multi-tenancy? And no namespaces are not Multi-tenancy...

  • popeye

    ๐Ÿ‘€ A Kubernetes cluster resource sanitizer

    • Project mention: Upgrading Hundreds of Kubernetes Clusters | dev.to | 2024-04-03

    • Project mention: Rainbond: No Need Understand Kubernetes Application Management Platform | news.ycombinator.com | 2023-09-20

  • opencost

    Cost monitoring for Kubernetes workloads and cloud costs

    • Project mention: Show HN: Cloud Costs Monitoring in Docker | news.ycombinator.com | 2023-11-21

    OpenCost is an open source implementation for Kubernetes cost monitoring and now cloud cost monitoring for AWS, Azure, and GCP. The project makes all of this data accessible via an API and user interface. While discussing the idea of running OpenCost on platforms besides Kubernetes we realized that with this new Cloud Costs feature there are users who want API access to their cloud billing data without needing to run on Kubernetes. I opened the Issue OpenCost without Kubernetes #2268 and as luck would have it, we had our internal Hackathon last week.

    If you're not familiar with OpenCost, it's the open source CNCF project for monitoring Kubernetes and cloud spending. It's a Golang implementation of the OpenCost Specification for monitoring Kubernetes cloud costs. It has an optional web UI and you can also run it as a Prometheus metrics exporter. The code is all at https://github.com/opencost/opencost and you can learn more about the project at https://opencost.io

  • kubernetes-ingress

    Everything in the YAML snippets below โ€” except for ingress configuration โ€” relates to configuring the NGINX ingress controller. This includes customizing the default configuration.

  • kruise

    Automated management of large-scale applications on Kubernetes (incubating project under CNCF)

  • litmus

    • Project mention: Building Resilience with Chaos Engineering and Litmus | dev.to | 2023-06-10

    Litmus, Gremlin, Chaos Mesh, and Chaos Monkey are all popular open-source tools used for chaos engineering. As we will be using AWS cloud infrastructure, we will also explore AWS Fault Injection Simulator (FIS). While they share the same goals of testing and improving the resilience of a system, there are some differences between them. Here are some comparisons:

  • arkade

    Open Source Marketplace For Developer Tools

    • Project mention: Understand your usage of GitHub Actions | news.ycombinator.com | 2023-06-18

    If you omit sudo, then you can move the binary yourself.

    And of course, there's nothing stopping you visiting the releases page - or installing my tap and getting it from Brew!

    https://github.com/alexellis/arkade/releases

  • karmada

    Open, Multi-Cloud, Multi-Cluster Kubernetes Orchestration

    • Project mention: Mirantis Unveils K0smotron: An Open-Source Kubernetes Management Project | news.ycombinator.com | 2023-08-04

    Sounds similiar to Karmada, which we use at EdgeNode.com
