Manage images using cURL

Manage images using cURL¶

This section is intended to provide a series of commands a typical client of the API might use to create and modify an image.

These commands assume the implementation of the v2 Image API using the Identity Service for authentication and authorization. The X-Auth-Token header is used to provide the authentication token issued by the Identity Service.

The strings $OS_IMAGE_URL and $OS_AUTH_TOKEN represent variables defined in the client’s environment. $OS_IMAGE_URL is the full path to your image service endpoint, for example, http://example.com. $OS_AUTH_TOKEN represents an auth token generated by the Identity Service, for example, 6583fb17c27b48b4b4a6033fe9cc0fe0.

Create an image¶

$ curl -i -X POST -H "X-Auth-Token: $OS_AUTH_TOKEN" \
       -H "Content-Type: application/json" \
       -d '{"name": "Ubuntu 14.04", \
       "tags": ["ubuntu", "14.04", "trusty"]}' \
       $OS_IMAGE_URL/v2/images
