Openshift Tutorials - Deployments

Source-to-Image (S2I) is a framework that makes it easy to write images that take application source code as an input and produce a new image that runs the assembled application as output.

The main advantage of using S2I for building reproducible container images is the ease of use for developers. As a builder image author, you must understand two basic concepts in order for your images to provide the best possible S2I performance: the build process and S2I scripts.

A template describes a set of objects that can be parameterized and processed to produce a list of objects for creation by the OpenShift Container Platform. A template can be processed to create anything you have permission to create within a project, for example, services, build configurations, and DeploymentConfigs. A template may also define a set of labels to apply to every object defined in the template.

You can create a list of objects from a template using the CLI or, if a template has been uploaded to your project or the global template library, using the web console.
