Convert any npm package into a runnable container
$ npm2dock micro-sleep
Downloads the latest stable version (npm install behaviour) of the micro-sleep
package and creates a docker image named micro-sleep with a tag corresponding
to the version of the resolved package.
$ npm2dock micro-sleep@1.0.1
Does the same thing but resolves to the 1.0.1 version of the package (npm install behaviour)
This then generates the micro-sleep:1.0.1 image on your docker.
Once you've generated your images, they can be run anywhere like this for example
$ docker run -d -p 3000:3000 micro-sleep:1.0.0
npm2dock makes 3 main assumptions about the structure of the packages it pulls from npm:
- it has an
npm startscript configured - it starts a server on at least one of these ports: 3000 8000 8080 8443 (or on the PORT environment variable)
- it only needs a node.js runtime to run.
Additionnally it is strongly recommended that configuration is made via ENV variables
If the package you want to run follows these, then life will be a breeze anyway.
the npm2dock executable itself is a bash script relying on the presence of
Docker on the host.
- bash
- docker
- npm
Almost nothing. The source code is shorter than this README.
npm2dock currently uses the mhart/alpine-node image as a base for its reasonable size.
