NodeJS container images

This repository contains the source for building various versions of the Node.JS application as a reproducible container image using source-to-image. Users can choose between RHEL and CentOS based builder images. The resulting image can be run using Docker.

Versions

Node.JS versions currently provided are:

• NodeJS 6
• NodeJS 8

RHEL versions currently supported are:

• RHEL7

CentOS versions currently supported are:

• CentOS7

Installation

To build a Node.JS image, choose either the CentOS or RHEL based image:

• CentOS based image

  This image is available on DockerHub. To download it run:

  $ docker pull kubespheredev/nodejs-8-centos7
  

  To build a Node.JS image from scratch run:

  $ git clone --recursive https://github.com/kubesphere/s2i-nodejs-container.git
  $ cd s2i-nodejs-container
  $ git submodule update --init
  $ make build TARGET=centos7 VERSIONS=8
  

Notice: By omitting the VERSIONS parameter, the build/test action will be performed on all provided versions of Node.JS.

Usage

For information about usage of Dockerfile for NodeJS 6, see usage documentation. For information about usage of Dockerfile for NodeJS 8, see usage documentation.

Test

This repository also provides a S2I test framework, which launches tests to check functionality of a simple Node.JS application built on top of the s2i-nodejs image.

Users can choose between testing a Node.JS test application based on a RHEL or CentOS image.

• RHEL based image

  To test a RHEL7 based Node.JS image, you need to run the test on a properly subscribed RHEL machine.

  $ cd s2i-nodejs-container
  $ git submodule update --init
  $ make test TARGET=rhel7 VERSIONS=8
  

• CentOS based image

  $ cd s2i-nodejs-container
  $ git submodule update --init
  $ make test TARGET=centos7 VERSIONS=8
  

Notice: By omitting the VERSIONS parameter, the build/test action will be performed on all provided versions of Node.JS.

Repository organization

• <nodejs-version>

  • Dockerfile

    CentOS based Dockerfile.

  • Dockerfile.rhel7

    RHEL based Dockerfile. In order to perform build or test actions on this Dockerfile you need to run the action on a properly subscribed RHEL machine.

  • s2i/bin/

    This folder contains scripts that are run by S2I:

    • assemble

      Used to install the sources into the location where the application will be run and prepare the application for deployment (eg. installing modules using npm, etc.)

    • run

      This script is responsible for running the application, by using the application web server.

    • usage*

      This script prints the usage of this image.

  • contrib/

    This folder contains a file with commonly used modules.

  • test/

    This folder contains the S2I test framework with simple Node.JS echo server.

    • test-app/

      A simple Node.JS echo server used for testing purposes by the S2I test framework.

    • run

      This script runs the S2I test framework.
