--> Found Docker image 3fa8225 (2 weeks old) from Docker Hub for "centos:centos7"

    * An image stream will be created as "centos:centos7" that will track the source image
    * A Docker build using source code from git@github-isl-01.ca.com:garju09/docker-sleep.git will be created
      * The resulting image will be pushed to image stream "docker-sleep:latest"
      * Every time "centos:centos7" changes a new build will be triggered
      * WARNING: this source repository may require credentials.
                 Create a secret with your git credentials and use 'set build-secret' to assign it to the build config.
    * This image will be deployed in deployment config "docker-sleep"
    * The image does not expose any ports - if you want to load balance or send traffic to this component
      you will need to create a service with 'expose dc/docker-sleep --port=[port]' later
    * WARNING: Image "centos:centos7" runs as the 'root' user which may not be permitted by your cluster administrator
