2016/10/12 - Amazon EC2 Container Registry - 1 new 3 updated api methods
Changes DescribeImages is a new api used to expose image metadata which today includes image size and image creation timestamp.
Returns metadata about the images in a repository, including image size and creation date.
Note
Beginning with Docker version 1.9, the Docker client compresses image layers before pushing them to a V2 Docker registry. The output of the docker images command shows the uncompressed image size, so it may return a larger image size than the image sizes returned by DescribeImages.
Request Syntax
client.describe_images(
registryId='string',
repositoryName='string',
imageIds=[
{
'imageDigest': 'string',
'imageTag': 'string'
},
],
nextToken='string',
maxResults=123,
filter={
'tagStatus': 'TAGGED'|'UNTAGGED'
}
)
string
The AWS account ID associated with the registry that contains the repository in which to list images. If you do not specify a registry, the default registry is assumed.
string
[REQUIRED]
A list of repositories to describe. If this parameter is omitted, then all repositories in a registry are described.
list
The list of image IDs for the requested repository.
(dict) --
An object with identifying information for an Amazon ECR image.
imageDigest (string) --
The sha256 digest of the image manifest.
imageTag (string) --
The tag used for the image.
string
The nextToken value returned from a previous paginated DescribeImages request where maxResults was used and the results exceeded the value of that parameter. Pagination continues from the end of the previous results that returned the nextToken value. This value is null when there are no more results to return.
integer
The maximum number of repository results returned by DescribeImages in paginated output. When this parameter is used, DescribeImages only returns maxResults results in a single page along with a nextToken response element. The remaining results of the initial request can be seen by sending another DescribeImages request with the returned nextToken value. This value can be between 1 and 100. If this parameter is not used, then DescribeImages returns up to 100 results and a nextToken value, if applicable.
dict
The filter key and value with which to filter your DescribeImages results.
tagStatus (string) --
The tag status with which to filter your DescribeImages results. You can filter results based on whether they are TAGGED or UNTAGGED .

Response Structure
(dict) --
imageDetails (list) --
A list of ImageDetail objects that contain data about the image.
(dict) --
An object that describes an image returned by a DescribeImages operation.
registryId (string) --
The AWS account ID associated with the registry to which this image belongs.
repositoryName (string) --
The name of the repository to which this image belongs.
imageDigest (string) --
The sha256 digest of the image manifest.
imageTags (list) --
The list of tags associated with this image.
(string) --
imageSizeInBytes (integer) --
The size, in bytes, of the image in the repository.
Note
Beginning with Docker version 1.9, the Docker client compresses image layers before pushing them to a V2 Docker registry. The output of the docker images command shows the uncompressed image size, so it may return a larger image size than the image sizes returned by DescribeImages.
imagePushedAt (datetime) --
The date and time, expressed in standard JavaScript date format, at which the current image was pushed to the repository.
nextToken (string) --
The nextToken value to include in a future DescribeImages request. When the results of a DescribeImages request exceed maxResults , this value can be used to retrieve the next page of results. This value is null when there are no more results to return.
{'repository': {'createdAt': 'timestamp'}}
Creates an image repository.
Request Syntax
client.create_repository(
repositoryName='string'
)
string
[REQUIRED]
The name to use for the repository. The repository name may be specified on its own (such as nginx-web-app ) or it can be prepended with a namespace to group the repository into a category (such as project-a/nginx-web-app ).

The date and time, in JavaScript date/time format, when the repository was created.
{'repository': {'createdAt': 'timestamp'}}
Deletes an existing image repository. If a repository contains images, you must use the force option to delete it.
Request Syntax
client.delete_repository(
registryId='string',
repositoryName='string',
force=True|False
)
string
The AWS account ID associated with the registry that contains the repository to delete. If you do not specify a registry, the default registry is assumed.
string
[REQUIRED]
The name of the repository to delete.
boolean
Force the deletion of the repository if it contains images.
