Similarly, what is image in OpenShift?

An image stream and its associated tags provide an abstraction for referencing Docker images from within OpenShift Container Platform. The image stream and its tags allow you to see what images are available and ensure that you are using the specific image you need even if the image in the repository changes.

Secondly, what is builder image? The builder image contains the specific intelligence required to produce that executable image (also known as a build artifact). The total build process involves several steps, including the invocation of the builder image.

Also, how do I create an OpenShift image?

Using OpenShift Container Platform for building the image Once you have a Dockerfile and the other artifacts that make up your new S2I builder image, you can put them in a git repository and use OpenShift Container Platform to build and push the image. Simply define a Docker build that points to your repository.
