Adding an Image Member

Scenario

A private image can be shared with other tenants. When sharing an image, you need add a project ID of the tenant with whom you are going to share the image.

• Currently, images can be shared only within the same region.
• The token obtained from Identity and Access Management (IAM) is valid for only 24 hours. If you want to use a token for authentication, you can cache it to avoid frequently calling the IAM API.

Involved APIs

If you use a token for authentication, you must obtain the token and add X-Auth-Token to the request header of the IMS API when making an API call.

• IAM API used to obtain the token

  URI format: POST https://IAM endpoint/v3/auth/tokens

• IMS API used to add an image member (Native OpenStack API)

  URI format: POST https://IMS endpoint/v2/images/Image ID/members

Procedure

1. Obtain the token.
2. Send POST https://IMS endpoint/v2/images/Image ID/members.
3. Add X-Auth-Token to the request header.
4. Specify the following parameters in the request body:

   {
       "member": "edc89b490d7d4392898e19b2deb34797"  //Member ID (that is, project ID of the image recipient)
   }

5. Check the response parameters.

   {
       "status": "pending",  //Image is being shared
       "created_at": "2016-09-01T02:05:14Z",  //Time when the image is shared
       "updated_at": "2016-09-01T02:05:14Z", //Time when the image status is updated
       "image_id": "d164b5df-1bc3-4c3f-893e-3e471fd16e64",  //Image ID
       "member_id": "edc89b490d7d4392898e19b2deb34797"  //Member ID (that is, project ID of the image recipient)
       "schema": "/v2/schemas/member"  //Image sharing schema
   }
