ImageBuilder: InvalidParameterValueException thrown for valid Arn

[Ashex]

An arn retrieved via the list_components operation throws an exception when passed to get_component:

import boto3
imagebuilder = boto3.client('imagebuilder')
for component in imagebuilder.list_components(owner='Amazon')['componentVersionList']:
    imagebuilder.get_component(componentBuildVersionArn=component['arn'])

Traceback (most recent call last):
  File "<input>", line 2, in <module>

'componentBuildVersionArn' must match pattern ^arn:aws[^:]*:imagebuilder:[^:]+:(?:\d{12}|aws):component/[a-z0-9-_]+/\d+\.\d+\.\d+/\d+$

Component arn returned from list_components:
arn:aws:imagebuilder:eu-west-1:aws:component/python-3-linux/1.0.0

Component arn returned from create_component:
arn:aws:imagebuilder:eu-west-1:01234567890:component/foo/0.0.13/1

It's not clear what the /1 suffix is for.

Interestingly, I can create an Image Recipe with a mix of these Arns and validation passes. The pipeline created with this recipe successfully generates an image.

Reproduced on boto3 1.10.33 and 1.10.34

Try appending "/1" to the ARNs you get back. I haven't been able to find resources to identify what that /1 is supposed to represent. You can't create a /2 version with the same semantic-version, so I'm not sure why it's there. The ARN regexes seem to require it even though the ARNs aren't always represented with that extra digit.

I noticed the same. The console shows arns with the /1 suffix, adding that allows get_component to succeed.

Interestingly, create_component returns the arn with the /1 suffix.

The same issue exists for Image Arns:

for image in imagebuilder.list_images(owner='Self')['imageVersionList']:
    imagebuilder.delete_image(imageBuildVersionArn=image['arn'])

@Ashex - Thank you for your post. You have to pass the arn, got from list_components to list_components_build_versions and then use that arn with get_component call. Something like this:

import boto3
imagebuilder = boto3.client('imagebuilder')

for component in imagebuilder.list_components(owner='Self')['componentVersionList']: 
           print(component['arn']) 

arn:aws:imagebuilder:us-west-2:123456789:component/test-component/1.1.1

Then use this arn with list_component_build_versions

imagebuilder.list_component_build_versions(componentVersionArn='arn:aws:imagebuilder:us-west-2:123456789:component/test-component/1.1.1')


'componentSummaryList': [{'arn': 'arn:aws:imagebuilder:us-west-2:123456789:component/test-component/1.1.1/1',
   'name': 'test_component',
   'version': '1.1.1',
   'platform': 'Linux',
   'type': 'TEST',
   'owner': '504809190933',
   'dateCreated': '2019-12-11T18:53:04.937Z',
   'tags': {}}]}

Now you can use this arn with get_component api call

imagebuilder.get_component(componentBuildVersionArn='arn:aws:imagebuilder:us-west-2:123456789:component/test-component/1.1.1/1') 

It is same for image_versions and image_build_versions. Each time a pipeline creates an image, it is creating a new image build version (example: /1, /2, etc.). So with image_versions the arn of all image of a pipeline will be same and in that case you have to use image_build_versionsto get the particular arn.

Hope it helps.
