    Origin S2I NodeJS

    Build Status

    This repository contains sources for an s2i builder image, based on CentOS7 and Node.js releases from nodejs.org.

    If you are interested in developing against SCL-based Node.js releases, try sti-nodejs.

    docker hub stats

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

    Versions

    Node.js versions currently provided:

    • 7.9.0: (7.9.0, 7, 7.9, current, latest)
    • 6.10.3: (6.10.3, 6, 6.10, lts, Boron)
    • 5.12.0: (5.12.0, 5, 5.12)
    • 4.8.3: (4.8.3, 4, 4.8, lts, Argon)

    Operating systems currently provided are: centos7, fedora, rhel7-atomic and rhel7

    Usage

    OpenShift allows you to quickly start a build using the web console, or the CLI.

    The oc command-line tool can be used to start a build, layering your desired nodejs REPO_URL sources into a centos7 image with your selected RELEASE of Node.js via the following command format:

    oc new-app bucharestgold/centos7-s2i-nodejs:RELEASE~REPO_URL
    

    For example, you can run a build (including npm install steps), using s2i-nodejs example repo, and the current relase of Node.js with:

    oc new-app bucharestgold/centos7-s2i-nodejs:current~https://github.com/bucharest-gold/s2i-nodejs
    

    Or, to run the latest lts release:

    oc new-app bucharestgold/centos7-s2i-nodejs:lts~https://github.com/bucharest-gold/s2i-nodejs
    

    You can try using any of the available tagged Node.js releases, and your own repo sources - as long as your application source will init correctly with npm start, and listen on port 8080.

    Environment variables

    Application developers can use the following environment variables to configure the runtime behavior of this image:

    NAME Description
    NPM_RUN Select an alternate / custom runtime mode, defined in your package.json file's scripts section (default: npm run "start")
    NPM_MIRROR Sets the npm registry URL
    NODE_ENV Node.js runtime mode (default: "production")
    HTTP_PROXY use an npm proxy during assembly
    HTTPS_PROXY use an npm proxy during assembly

    One way to define a set of environment variables is to include them as key value pairs in your repo's .s2i/environment file.

    Example: DATABASE_USER=sampleUser

    Using Docker's exec

    To change your source code in a running container, use Docker's exec command:

    docker exec -it <CONTAINER_ID> /bin/bash
    

    After you Docker exec into the running container, your current directory is set to /opt/app-root/src, where the source code for your application is located.

    Using OpenShift's rsync

    If you have deployed the container to OpenShift, you can use oc rsync to copy local files to a remote container running in an OpenShift pod.

    Builds

    The Source2Image cli tools are available as a standalone project, allowing you to run builds outside of OpenShift.

    This example will produce a new docker image named webapp:

    s2i build https://github.com/bucharest-gold/s2i-nodejs bucharestgold/centos7-s2i-nodejs:current webapp
    

    Installation

    There are several ways to make this base image and the full list of tagged Node.js releases available to users during OpenShift's web-based "Add to Project" workflow.

    For OpenShift Online Next Gen Developer Preview

    Those without admin privileges can install the latest Node.js releases within their project context with:

    oc create -f https://raw.githubusercontent.com/bucharest-gold/origin-s2i-nodejs/master/image-streams.json
    

    To ensure that each of the latest Node.js release tags are available and displayed correctly in the web UI, try upgrading / reinstalling the image stream:

    oc delete is/centos7-s2i-nodejs ; oc create -f https://raw.githubusercontent.com/bucharest-gold/origin-s2i-nodejs/master/image-streams.json
    

    If you've (automatically) imported this image using the oc new-app example command, then you may need to clear the auto-imported image stream reference and re-install it.

    For Administrators

    Administrators can make these Node.js releases available globally (visible in all projects, by all users) by adding them to the openshift namespace:

    oc create -n openshift -f https://raw.githubusercontent.com/bucharest-gold/origin-s2i-nodejs/master/image-streams.json
    

    To replace the default SCL-packaged openshift/nodejs image (admin access required), run:

    oc delete is/nodejs -n openshift ; oc create -n openshift -f https://raw.githubusercontent.com/bucharest-gold/origin-s2i-nodejs/master/centos7-s2i-nodejs.json
    

    Building your own Builder images

    Clone a copy of this repo to fetch the build sources:

    git clone https://github.com/bucharest-gold/origin-s2i-nodejs.git
    cd origin-s2i-nodejs
    

    To build your own S2I Node.js builder images from scratch, run:

    make build
    

    You can also build a specific release, or try building the alternate ONBUILD version of this base:

    ONBUILD=true make VERSION=6.3.1
    

    The ONBUILD base images are available at https://hub.docker.com/r/bucharestgold/centos7-nodejs

    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 origin-s2i-nodejs image.

    make test
