@digitalroute/npm-helm NPM

npm-helm

Helm helper module for nodejs

Usage

Like usual:

npm install @digitalroute/npm-helm --save-dev

And add the following parts to your package.json (you may already have a config section, so add it inside there if you already have it.)

  "config": {
    "helm": {
      "name": "<name-of-service>",
      "repository": "<helm-repo-name>",
      "namespace": "<kubernetes-namespace>",
      "imageRepository": "<docker-registry-for-image>",
      "binary": "<helm-binary-to-use>"
    },
  },

  "scripts": {
    "helm": "npm-helm",
    "helm-install": "npm-helm docker-build package install",
  },
