NodeJS Docker images

This repository contains the source for building various versions of the Node.JS application as a reproducible Docker image using source-to-image. The resulting image can be run using Docker.

For more information about using these images with OpenShift, please see the official OpenShift Documentation.

For more information about contributing, see the Contribution Guidelines. For more information about concepts used in these docker images, see the Landing page.

Versions

Node.JS versions currently provided are:

• NodeJS 4
• NodeJS 6
• NodeJS 8

Linux Alpine versions currently supported are:

• Alpine3

Installation

To build a Node.JS image:

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

```
$ docker pull eduardomourar/s2i-node-alpine
```

To build a Node.JS image from scratch run:

```
$ git clone --recursive https://github.com/eduardomourar/s2i-node-alpine
$ cd s2i-node-alpine
$ git submodule update --init
$ make build TARGET=alpine3 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 4, see usage documentation. 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 Alpine image.

```
$ cd s2i-node-alpine
$ git submodule update --init
$ make test TARGET=alpine3 VERSIONS=8
```

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