node-image-stream

Description

This is a simple utility that takes JSON input from node-metadata, and converts it to ImageStream JSON for OpenShift.

See the OpenShift documentation for more information about using the output from this tool to customize your Node.js runtime on OpenShift/Kubernetes.

Usage

You'll need node-metadata and this package installed. Then you can just pipe the output from node-metadata into node-image-stream to generate JSON suitable for import into OpenShift.

$ npm install -g node-image-stream
 
$ node-image-stream --help
Usage:
  node-image-stream [OPTIONS] [ARGS]
 
Options:
  -f, --file FILE        A file to process
  -i, --image STRING     The image name
  -h, --help             Display help and usage details
 
$ npm install -g node-metadata
 
$ node-metadata --help
 
  Usage: node-metadata [options]
 
  Options:
 
    -h, --help     output usage information
    -V, --version  output the version number
    -i --images    Indicates what images to show.
 
$ node-metadata -i 6 8 | node-image-stream -i bucharestgold/centos7-s2i-nodejs

This will print to STDOUT. You can redirect to a file if you want:

$ node-metadata -i 6 8 | node-image-stream -i bucharestgold/centos7-s2i-nodejs > image-streams.json

Or you can read input from a file.

$ node-image-stream -i bucharestgold/centos7-s2i-nodejs -f ../centos7-s2i-nodejs/releases.json

The output will look something like this. Note that the image name provided on the command line should be resolvable to a docker image in a registry accessible to OpenShift.
