OpenShift Builder Images for Node.js Applications
This repository contains sources for an s2i builder image, based on CentOS7 and Node.js releases from nodejs.org.
For more information about using these images with OpenShift, please see the
official OpenShift Documentation.
Node.js versions currently provided:
<!-- versions.start -->
9.8.0: (9.x, latest)
8.10.0: (8.x, Carbon)
6.11.4: (6.x, Boron)
4.8.4: (4.x, Argon)
<!-- versions.end -->
Using this image with OpenShift
oc command line tool, or with
s2i directly, will
assemble your application source with any required dependencies to create a new image.
This resulting image contains your Node.js application and all required dependencies,
and can be run either by OpenShift Origin or by Docker.
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
latest release of
oc new-app bucharestgold/centos7-s2i-nodejs:latest~https://github.com/bucharest-gold/s2i-nodejs
<!-- Or, to run the latest `lts-6` release: ``` oc new-app bucharestgold/centos7-s2i-nodejs:lts-6~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. -->
Use the following environment variables to configure the runtime behavior of the
application image created from this builder image.
|NPM_RUN||Select an alternate / custom runtime mode, defined in your
|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
.s2i/environment file in your source repository.
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.
This example will produce a new docker image named
s2i build https://github.com/bucharest-gold/s2i-nodejs bucharestgold/centos7-s2i-nodejs:current webapp
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/centos7-s2i-nodejs/master/image-streams.centos7.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/centos7-s2i-nodejs/master/image-streams.centos7.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.
Administrators can make these Node.js releases available globally (visible in all projects, by all users) by adding them to the
oc create -n openshift -f https://raw.githubusercontent.com/bucharest-gold/centos7-s2i-nodejs/master/image-streams.centos7.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/centos7-s2i-nodejs.git cd centos7-s2i-nodejs
Requirements - docker-squash
pip install docker-squash
To build your own S2I Node.js builder images from scratch, run:
