kubenix

Kubernetes management with Nix

WARN: this is a work in progress, expect breaking changes

Usage

A minimal example flake (build with nix build):

{
  inputs.kubenix.url = "github:hall/kubenix";
  outputs = {self, kubenix, ... }@inputs: let
    system = "x86_64-linux";
  in {
    packages.${system}.default = (kubenix.evalModules.${system} {
      module = { kubenix, ... }: {
        imports = with kubenix.modules; [k8s];
        kubernetes.resources.pods.example.spec.containers.nginx.image = "nginx";
      };
    }).config.kubernetes.result;
  };
}

Or, if you're not using flakes, a default.nix file (build with nix-build):

{ kubenix ? import (builtins.fetchGit {
  url = "https://github.com/hall/kubenix.git";
  rev = "aa734afc9cf7a5146a7a9d93fd534e81572c8122";
}) }:
(kubenix.evalModules.x86_64-linux {
  module = {kubenix, ... }: {
    imports = with kubenix.modules; [k8s];
    kubernetes.resources.pods.example.spec.containers.nginx.image = "nginx";
  };
}).config.kubernetes.result

Either way the JSON manifests will be written to ./result.

See the examples for more.

CLI

NOTE: this is a WIP CLI which currently reads the k8s package on a local flake

Render all resources with

nix run github:hall/kubenix -- render

HINT: use --help for more commands

Logo is a mishmash of the Kubernetes wheel and the NixOs snowflake.

1. piping rendered helm charts to kubectl is a lossy process (e.g., hooks will not work) ↩︎

2. currently create-only ↩︎
