Chapter 40. Create from URL
40.1. Overview
Create From URL is a function that allows you to construct a URL from an image stream, image tag, or template.
Create from URL only works with image streams or templates from namespaces that have been explicitly whitelisted. The whitelist contains the openshift namespace by default. To add namespaces to the whitelist, see Configuring the Create From URL Namespace Whitelist.
You can define custom buttons.
These buttons leverage a defined URL pattern with an appropriate query string. The user is prompted to select the project. Then, the Create from URL workflow continues.
