Installing Node.js dependencies with Yarn via s2i builds and OpenShift

Building a docker formatted container image for a Node.js application

There are 2 main strategies for building an image for a Node.js Application. The most common strategy is simply using a Dockerfile with a base image of something like FROM node:4-onbuild. Then do a docker build. This will produce an image with your application in it, ready to be run. This strategy is known as the Docker strategy in an OpenShift BuildConfig.

Another strategy is using the s2i tool for taking the application source from a repository and producing the image. A typical command would be.s2i build git@github.com/me/myrepo.git bucharestgold/centos7-s2i-nodejs:latest myapp. With this strategy, there is no explicit Dockerfile. It is known as the Source strategy in an OpenShift BuildConfig.

No cost. No hassle. Plenty of RHEL Developer Benefits

A year ago Red Hat announced the availability of a no-cost Red Hat Enterprise Linux developer subscription available as part of the Red Hat Developer Program. Offered as a self-supported, development-only subscription, this developer subscriptions provides you with a stable development platform for building enterprise applications – across cloud, physical, virtual, and container-centric infrastructures.

Adoption has been excellent since then, but I was prompted (aka nudged, voluntold) to remind “non users” (yes, some of you are still out there) what it is and how to get it. But I’ll also explain to “users” how to easily re-subscribe (it’s still free) if your 12-month subscription is up.  First, here’s what you “non-users” can get if you become “users”:
