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.

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.
