Top 23 K8 Open-Source Projects

  • minio

    The Object Store for AI Data Infrastructure

    • Project mention: JuiceFS 1.2 Beta 1: Gateway Upgrade, Enhanced Multi-User Permission Management | dev.to | 2024-05-05

    The core service of JuiceFS Gateway is to expose the POSIX file system via the S3 API. Before v1.2, we integrated the MinIO Gateway module into our code. This module was based on the Apache license. This integration made JuiceFS operations similar to MinIO's native command minio gateway NAS. For users, JuiceFS could be seen as an implementation of MinIO Gateway. MinIO's other backend implementations include NAS and Hadoop.

  • k3s

    Lightweight Kubernetes

    • Project mention: Ask HN: Are there any open source forks of nomad smd consul? | news.ycombinator.com | 2024-05-02

    Opinionated meaning it picks, install, patches your CNI/Ingress/Load Balancer/DNS Server/Metrics Server/Monitoring Setup.

    k3s is probably most well known as it ships with bunch of preinstall software: https://github.com/k3s-io/k3s so you can just start throwing yaml files at cluster and handling workloads. It's what I use for my homelab.

    Paid things I've heard of include OpenStack and SideroLabs. Haven't used personally by SRE coworkers say good things about them.

  • InfluxDB

    Power Real-Time Data Analytics at Scale. Get real-time insights from all types of time series data with InfluxDB. Ingest, query, and analyze billions of data points in real-time with unbounded cardinality.

    • Project mention: Serverless Functions, Made Simple | news.ycombinator.com | 2024-04-11

  • cilium

    eBPF-based Networking, Security, and Observability

    • Project mention: Cisco to Acquire Cloud Native Networking and Security Leader Isovalent | news.ycombinator.com | 2023-12-21

    They would have had to add a few externals to get to Graduated but it's definitely a minority:

  • colima

    Container runtimes on macOS (and Linux) with minimal setup

    • Project mention: How I ended up using Colima for Docker on Apple Silicon | dev.to | 2024-05-03

    While looking into the issue with Podman, I came across colima. Apart from being able to run AMD64 images out of the box, there were additional benefits to it, one of which was, unlike podman, colima could use Rosetta 2 for x64 emulation (which is significantly more performant).

  • 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: List of ngrok/Cloudflare Tunnel alternatives and other tunneling software and services. Focus on self-hosting. | dev.to | 2024-04-30

    Netmaker - Layer 3 peer-to-peer overlay network and private DNS. Similar to Tailscale, but with a self-hosted server/admin UI. Runs kernel WireGuard so very fast. Not FOSS, but the source code is available. Written in Go.

  • openebs

    • Project mention: You get what you Measure: Understanding your applications health with Grafana, Loki and Prometheus | dev.to | 2024-04-24

    If you want hands-on practice you should have a running Kubernetes cluster (I used MicroK8s for this tutorial) and Helm (see how to install on Installing Helm tutorial). It is important that you understand the basics of these tools to fully understand.

  • 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 – [✩Star] 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.

    • 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...
