node-docker-tools v0.0.7

node-docker-tools

Docker made easy

Commands

npm exec node-docker-tools generate      # Generate a Dockerfile based on package.json
npm exec node-docker-tools build         # Build the image
npm exec node-docker-tools run           # Build the image and then run the container

Config

Config should reside in the root of your project and be named node-docker-tools.config.js. A configuration file is often not needed though as node-docker-tools by default derives configuration from your environment.

const { Config } = require("node-docker-tools/config");

/** @type {Config} */
module.exports = {
  projectName: "myapp",             // Default derived from package.json
  projectVersion: "1.2.3",          // Default derived from package.json
  framework: "nextjs",              // Default derived from package.json
  nodeVersion: "21",                // Default derived from node -v
  envFile: ".dotenv.local"          // Default .env.local or .env present
};

Examples

Example projects using different frameworks can be found under /examples and is an easy way of playing around with node-docker-tools in different contexts.

To execute a local npx script within the context of an example app just go to the project dir and run the script from there. Moving to the root project dir is important as the scripts often assume cwd contains config files like package.json.

cd examples/nextjs
npx ../../src/npx/generate.js

Publish a new version

To publish a new version to npm update the version in package.json and then run npm publish
