GET
/v2/images
List images

Lists public virtual machine (VM) images. (Since Image API v2.0.)

 

Returns a subset of the larger collection of images and a link that you can use to get the next set of images. You should always check for the presence of a next link and use it as the URI in a subsequent HTTP GET request. You should follow this pattern until a next link is no longer provided. The next link preserves any query parameters that you send in your initial request. You can use the first link to jump back to the first page of the collection. If you prefer to paginate through images manually, use the limit and marker parameters.

The list operation accepts several types of query parameters that let you filter the results of the returned collection.

A client can provide direct comparison filters using most image attributes, such as name=Ubuntu, visibility=public, and so on. A client cannot filter on tags or anything defined as a link in the json- schema, such as self, file, or schema.

You can use the size_min and size_max query parameters to perform greater-than and less-than filtering of images based on their size attribute. The size is measured in bytes and refers to the size of an image when it is stored on disk.

For example, sending a size_min filter of 1048576 and size_max of 4194304 filters the container to include only images that are between 1 and 4 MB.

You can see a list of VM images which status is in active, queued, or saving.

You can use query parameters to sort the results of this operation.

  • sort_key. Sorts by the requested image attribute. Sorts in the natural sorting direction of the image attribute that is provided as the sort_key.

  • sort_dir. Sorts in a specified sort direction.

  • sort. Sorts by one or more sets of attribute and sort direction combinations. If you omit the sort direction in a set, the default is desc.

To specify the sort_key and sort_dir query parameters to sort the results: 

GET /v2/images?sort_key=name&sort_dir=asc&sort_key=status&sort_dir=desc

To specify the sort query parameter to sort the results: 

GET /v2/images?sort=name:asc,status:desc

This operation does not accept a request body.

PATCH
/v2/images/​{image_id}​
Update image

Updates a specified image. (Since Image API v2.0.)

 

Depending on the referenced target location, this operation performs one of the following functions:

  • The target location is an array index. A new value is inserted into the array at the specified index.

  • The target location is an object member that does not exist. A new member is added to the object.

  • The target location is an object member that exists. The member value is replaced.

The operation object MUST contain a value member that specifies the value to add. For example: 

{
   "op": "add",
   "path": "/a/b/c",
   "value": [
      "foo",
      "bar"
   ]
}

The target location MUST reference one of these values:

  • The root of the target document. The specified value is the entire content of the target document.

  • A member to add to an object. The specified value is added to that object at the specified location. If the member already exists, it is replaced by the specified value.

  • An element to add to the array. The specified value is added to the array at the specified location. Any element that is at or above the specified index is shifted one position to the right. The specified index MUST NOT be greater than the number of elements in the array. If the hyphen (-) character is used to index the end of the array (see [RFC6901]), the value is appended to the array.

Because this operation adds to existing objects and arrays, its target location often does not exist.

The request body must conform to one of these media types:

  • application/openstack-images-v2.0-json-patch

  • application/openstack-images-v2.1-json-patch (Since Image API v2.2.)

You can also use the PATCH method to add or remove image properties.

For information about the PATCH method and the available media types, see Image API v2 HTTP PATCH media types.

Preconditions

  • When you add or replace a location to the specified image, you must set the disk_format and container_format parameters in the image.

  • When you replace a location, a location must be previously set in the image.

Synchronous Postconditions

  • With correct permissions, you can view the updated values of the attributes of the image.

  • After you add a location to an image that had no location and with correct permissions, you can use API calls to view the image status as active.

  • After you remove all locations from the image and with correct permissions, you can use API calls to view the image status as queued.

Troubleshooting

  • If you cannot update locations, your request might be missing some information. Make sure that you meet the preconditions and run the request again. If the request fails again, review your API request.

GET
/v2/metadefs/namespaces
List namespaces

Lists public namespaces.

 

Returns a subset in the larger collection of namespaces and a link that you can use to get the next set of namespaces. Check for the presence of a next link and use it as the URI in a subsequent HTTP GET request. Follow this pattern until a next link is no longer provided. The next link preserves any query parameters that you send in your initial request. You can use the first link to return to the first page in the collection. If you prefer to paginate through namespaces manually, use the limit and marker parameters.

The list operation accepts the resource_types and visibility query parameters, which let you filter the results in the returned collection.

To sort the results of this operation, use the sort_key and sort_dir parameters. The API uses the natural sorting order in the namespace attribute that you provide as the sort_key parameter.

marker (Optional) query xsd:string

Specifies the ID of the last-seen item. Use the limit parameter to make an initial limited request and use the ID of the last-seen item from the response as the marker parameter value in a subsequent limited request.

visibility (Optional) query imageapi:string

Filter parameter. Namespace visibility. Valid values are public and private. Default is public.

resource_types (Optional) query xsd:int

Filter parameter. Specify this value as comma- separated list. For example, send the resource_types filter of OS::Glance::Image,OS::Nova::Flavor to filter the namespaces by the specified resource types.

sort_key (Optional) query xsd:string

Sort key. Use attributes like namespace for sorting. Default is created_at.

Delete namespace

Deletes a specified namespace and its properties, objects, and any resource type associations.

 

You cannot delete namespaces with the protected attribute set to true (boolean); the response returns the HTTP 403 status code.

To delete a namespace, you must first make an update namespace request to set the protected attribute to false (boolean) on the namespace. Then, delete the namespace.

If the operation succeeds, the response returns the HTTP 204 status code.

If you try to remove a namespace with the protected attribute set to true (boolean), the operation fails and the response returns the HTTP 403 error code.

GET
/v2/metadefs/namespaces/​{namespace}​/objects
List objects

Lists object definitions within a namespace.

 

Returns a subset of the larger collection of namespaces and a link that you can use to get the next set of namespaces. You should always check for the presence of a next link and use it as the URI in a subsequent HTTP GET request. You should follow this pattern until a next link is no longer provided. The next link preserves any query parameters that you send in your initial request. You can use the first link to jump back to the first page of the collection. If you prefer to paginate through namespaces manually, use the limit and marker parameters.

The list operation accepts resource_types and visibility as query parameters that let you filter the results of the returned collection.

For example, sending a resource_types filter of OS::Glance::Image,OS::Nova::Flavor filters the namespaces to include only namespaces that are associated to the given resource types.

You can sort the results of this operation by using the sort_key and sort_dir parameters. The API uses the natural sorting of whatever namespace attribute is provided as the sort_key.
