Red Hat Developer Hub 1.3

Using dynamic plugins

Red Hat Customer Content Services

Abstract

The following sections provide information about how you can use RHDH dynamic plugins.

1. Using Ansible plug-ins for Red Hat Developer Hub

Ansible plug-ins for Red Hat Developer Hub deliver an Ansible-specific portal experience with curated learning paths, push-button content creation, integrated development tools, and other opinionated resources.

Important

The Ansible plug-ins are a Technology Preview feature only.

Technology Preview features are not supported with Red Hat production service level agreements (SLAs), might not be functionally complete, and Red Hat does not recommend using them for production. These features provide early access to upcoming product features, enabling customers to test functionality and provide feedback during the development process.

For more information on Red Hat Technology Preview features, see Technology Preview Features Scope.

Additional detail on how Red Hat provides support for bundled community dynamic plugins is available on the Red Hat Developer Support Policy page.

To use the Ansible plugins, see Using Ansible plug-ins for Red Hat Developer Hub.
