FILE: sample_delete_images_async.py
DESCRIPTION:
This sample demonstrates deleting all but the most recent three images for each repository.
USAGE:
python sample_delete_images_async.py
Set the environment variables with your own values before running the sample:
1) CONTAINERREGISTRY_ENDPOINT - The URL of your Container Registry account
This sample assumes your registry has at least one repository with more than three images,
run load_registry() if you don't have.
Set the environment variables with your own values before running load_registry():
1) CONTAINERREGISTRY_ENDPOINT - The URL of your Container Registry account
2) CONTAINERREGISTRY_TENANT_ID - The service principal's tenant ID
3) CONTAINERREGISTRY_CLIENT_ID - The service principal's client ID
4) CONTAINERREGISTRY_CLIENT_SECRET - The service principal's client secret
