Openshift Para los impacientes

Si bien no es la ultima version de openshift, ni la ultima version de fedora, les dejo acá los vagrant file y los scripts para que los impacientes puedan jugar con openshift.

Este es el script "script.sh", que es llamado por el vagranfile. Pero sino, bien puede ejecutarse sobre una instalacion limpia de fedora core 27.
