Overview

If a source code URL is specified, OpenShift will pull the source code and convert it into an image to run inside a pod, attempting to guess what build strategy to use. Local source must be in a Git repository that has a remote repository that the server can see. new-app will create a build configuration and a deployment configuration. A service will be connected to the first public port of the app. oc status can be used to check on progress.

oc new-app https://github.com/test/testapp.git

Successful creation output:

--> Found image eaf9dfd (5 weeks old) in image stream "openshift/nodejs" under tag "6" for "nodejs"

    Node.js 6
    ---------
    Node.js 6 available as docker container is a base platform for building and running various Node.js 6 applications and frameworks. Node.js is a platform built on Chrome's JavaScript runtime for easily building fast, scalable network applications. Node.js uses an event-driven, non-blocking I/O model that makes it lightweight and efficient, perfect for data-intensive real-time applications that run across distributed devices.

    Tags: builder, nodejs, nodejs6

    * The source repository appears to match: nodejs
    * A source build using source code from https://github.com/test/testapp will be created
      * The resulting image will be pushed to image stream "testapp:latest"
      * Use 'start-build' to trigger a new build
    * This image will be deployed in deployment config "testapp"
    * Port 8080/tcp will be load balanced by service "testapp"
      * Other containers can access this service through the hostname "testapp"
