Source to Image (S2I)
One of the useful components of OpenShift is its source-to-image capability. S2I is a framework that makes it easy to turn your source code into runnable images. The main advantage of using S2I for building reproducible docker images is the ease of use for developers. You’ll see just how simple it can be in this lab.
Let’s build a node.js web app, using S2I
We can do this either via the command line or the web console. You decide which you’d rather do and follow the steps below.
Note: When using the CLI, OpenShift automatically detects the source code type and select the nodejs builder image.
