Authentication
Entra ID (Recommended)
from azure.containerregistry import ContainerRegistryClient
from azure.identity import DefaultAzureCredential
client = ContainerRegistryClient(
endpoint=os.environ["AZURE_CONTAINERREGISTRY_ENDPOINT"],
credential=DefaultAzureCredential()
)
Anonymous Access (Public Registry)
from azure.containerregistry import ContainerRegistryClient
client = ContainerRegistryClient(
endpoint="https://mcr.microsoft.com",
credential=None,
audience="https://mcr.microsoft.com"
)
List Repositories
client = ContainerRegistryClient(endpoint, DefaultAzureCredential())
for repository in client.list_repository_names():
print(repository)
Repository Operations
Get Repository Properties
properties = client.get_repository_properties("my-image")
print(f"Created: {properties.created_on}")
print(f"Modified: {properties.last_updated_on}")
print(f"Manifests: {properties.manifest_count}")
print(f"Tags: {properties.tag_count}")
Update Repository Properties
from azure.containerregistry import RepositoryProperties
client.update_repository_properties(
"my-image",
properties=RepositoryProperties(
can_delete=False,
can_write=False
)
)
Delete Repository
client.delete_repository("my-image")
List Tags
for tag in client.list_tag_properties("my-image"):
print(f"{tag.name}: {tag.created_on}")
Filter by Order
from azure.containerregistry import ArtifactTagOrder
# Most recent first
for tag in client.list_tag_properties(
"my-image",
order_by=ArtifactTagOrder.LAST_UPDATED_ON_DESCENDING
):
print(f"{tag.name}: {tag.last_updated_on}")
Manifest Operations
List Manifests
from azure.containerregistry import ArtifactManifestOrder
for manifest in client.list_manifest_properties(
"my-image",
order_by=ArtifactManifestOrder.LAST_UPDATED_ON_DESCENDING
):
print(f"Digest: {manifest.digest}")
print(f"Tags: {manifest.tags}")
print(f"Size: {manifest.size_in_bytes}")
Get Manifest Properties
manifest = client.get_manifest_properties("my-image", "latest")
print(f"Digest: {manifest.digest}")
print(f"Architecture: {manifest.architecture}")
print(f"OS: {manifest.operating_system}")
Update Manifest Properties
from azure.containerregistry import ArtifactManifestProperties
client.update_manifest_properties(
"my-image",
"latest",
properties=ArtifactManifestProperties(
can_delete=False,
can_write=False
)
)
Delete Manifest
# Delete by digest
client.delete_manifest("my-image", "sha256:abc123...")
# Delete by tag
manifest = client.get_manifest_properties("my-image", "old-tag")
client.delete_manifest("my-image", manifest.digest)
Tag Operations
Get Tag Properties
tag = client.get_tag_properties("my-image", "latest")
print(f"Digest: {tag.digest}")
print(f"Created: {tag.created_on}")
Delete Tag
client.delete_tag("my-image", "old-tag")
Upload and Download Artifacts
from azure.containerregistry import ContainerRegistryClient
client = ContainerRegistryClient(endpoint, DefaultAzureCredential())
# Download manifest
manifest = client.download_manifest("my-image", "latest")
print(f"Media type: {manifest.media_type}")
print(f"Digest: {manifest.digest}")
# Download blob
blob = client.download_blob("my-image", "sha256:abc123...")
with open("layer.tar.gz", "wb") as f:
for chunk in blob:
f.write(chunk)
Async Client
from azure.containerregistry.aio import ContainerRegistryClient
from azure.identity.aio import DefaultAzureCredential
async def list_repos():
credential = DefaultAzureCredential()
client = ContainerRegistryClient(endpoint, credential)
async for repo in client.list_repository_names():
print(repo)
await client.close()
await credential.close()
Clean Up Old Images
from datetime import datetime, timedelta, timezone
cutoff = datetime.now(timezone.utc) - timedelta(days=30)
for manifest in client.list_manifest_properties("my-image"):
if manifest.last_updated_on < cutoff and not manifest.tags:
print(f"Deleting {manifest.digest}")
client.delete_manifest("my-image", manifest.digest)

Best Practices
- Use Entra ID for authentication in production
- Delete by digest not tag to avoid orphaned images
- Lock production images with can_delete=False
- Clean up untagged manifests regularly
- Use async client for high-throughput operations
- Order by last_updated to find recent/old images
- Check manifest.tags before deleting to avoid removing tagged images
When to Use
This skill is applicable to execute the workflow or actions described in the overview.
AGI Framework Integration
Adapted for @techwavedev/agi-agent-kit Original source: antigravity-awesome-skills
Memory-First Protocol
Retrieve prior deployment configurations, rollback procedures, and incident post-mortems. Avoid re-discovering infrastructure patterns.
# Check for prior infrastructure context before starting
python3 execution/memory_manager.py auto --query "deployment configuration and patterns for Azure Containerregistry Py"
Storing Results
After completing work, store infrastructure decisions for future sessions:
python3 execution/memory_manager.py store \
--content "Deployment pipeline: configured blue-green deployment with health checks on port 8080" \
--type technical --project <project> \
--tags azure-containerregistry-py devops
Multi-Agent Collaboration
Broadcast deployment changes so frontend and backend agents update their configurations accordingly.
python3 execution/cross_agent_context.py store \
--agent "<your-agent>" \
--action "Deployed infrastructure changes — updated CI/CD pipeline with new health check endpoints" \
--project <project>
Playbook Integration
Use the ship-saas-mvp or full-stack-deploy playbook to sequence this skill with testing, documentation, and deployment verification.
