How can I administer an OpenStack cloud?
As an OpenStack cloud administrative user, you can manage tenants, known as projects, users, services, images, flavors, and quotas.
The examples in this guide show you how to perform tasks by using the following methods:
- OpenStack dashboard. Use this web-based graphical interface, code named horizon, to view, create, and manage resources and services.
- OpenStack command-line clients. Each core OpenStack project has a command-line client that you can use to run simple commands to view, create, and manage resources and services in a cloud and automate tasks by using scripts.
You can modify these examples for your specific use cases.
In addition to these ways of interacting with a cloud, you can access the OpenStack APIs directly or indirectly through cURL commands or open SDKs. You can automate access or build tools to manage resources and services by using the native OpenStack APIs or the EC2 compatibility API.
To use the OpenStack APIs, it helps to be familiar with HTTP/1.1, RESTful web services, the OpenStack services, and JSON or XML data serialization formats.
