Pull Request Overview

This PR adds comprehensive "compose-for-agents" support to the Azure Container Apps extension, enabling deployment of AI/ML workloads with models, MCP gateways, and GPU workload profiles through Docker Compose files.

Key Changes:

Models section support with automatic GPU workload profile provisioning and model-runner container deployment
MCP gateway auto-detection, managed identity enablement, and role assignment
Dry-run mode (--dry-run) for deployment preview without resource creation
x-azure-deployment custom extension for resource overrides (CPU, memory, ingress, images)

Reviewed Changes

Copilot reviewed 9 out of 9 changed files in this pull request and generated 11 comments.

+
+        # Return empty list (no actual deployment)
+        return None  # Dry-run complete, no resources created    return containerapps_from_compose


This line contains a syntax error with malformed text at the end. The line should end with return containerapps_from_compose but instead has return None # Dry-run complete, no resources created return containerapps_from_compose which mixes multiple return statements and a comment on a single line. This will cause a syntax error.

Suggested change

return None # Dry-run complete, no resources created return containerapps_from_compose

return None # Dry-run complete, no resources created

+        config_list = resolve_configuration_element_list(compose_service, unsupported_configuration, 'build')
+        message = "These build configuration settings from the docker-compose file are yet supported."


The message text contains "are yet supported" which is missing a word. This should read "are not yet supported" to be grammatically correct.

Suggested change

message = "These build configuration settings from the docker-compose file are yet supported."

message = "These build configuration settings from the docker-compose file are not yet supported."

+            # dry_run_has_models = True


The commented out code # if service_name == 'models': and # dry_run_has_models = True should either be removed or uncommented if needed. Leaving commented-out code reduces maintainability and can cause confusion about intended behavior.

Suggested change

# if service_name == 'models':

+            # Show allow insecure if target port is set
+            print(f"  Allow Insecure: true")


The dry-run print function always prints "Allow Insecure: true" when a target port is set (line 2074), but this should be conditional based on the actual allow_insecure configuration in the service. This creates misleading output that doesn't match the actual configuration that would be deployed.

Suggested change

# Show allow insecure if target port is set

print(f" Allow Insecure: true")

# Show allow insecure if present in config

if 'allow_insecure' in service_config:

print(f" Allow Insecure: {str(service_config['allow_insecure']).lower()}")

+        choice_index = prompt_choice_list(message, ports)
+
+    return ports[choice_index]
+
+


The variable choice_index is used without being initialized. In the case where len(ports) > 1, the code calls prompt_choice_list but doesn't assign the result. The next line return ports[choice_index] will cause a NameError. This should be: choice_index = prompt_choice_list(message, ports).

Suggested change

if len(ports) > 1:

message = f"You have more than one {name} mapping defined in your docker-compose file."

message += " Which port would you like to use? "

choice_index = prompt_choice_list(message, ports)

+                        import re


The import re statement is duplicated - it appears once at line 1761 and again at line 1817 and 1846. The module is already imported earlier in the conditional block, so these additional imports are redundant and should be removed.

+                gpu_type=gpu_profile.get('type') if (service_name == 'models' and 'gpu_profile' in locals()) else None,


The variable gpu_profile is referenced but never defined in this scope. The code checks if (service_name == 'models' and 'gpu_profile' in locals()) but gpu_profile is only assigned if models exist (line 1629-1664). If dry_run is True and this code path is reached for a non-models service, this will cause a NameError. Consider using gpu_profile_name instead, or ensure proper initialization.

+                service_name=service_name,
+                service=service,


[nitpick] The condition if min_replicas is not None will also handle the case when min_replicas is 0, which is a valid value. However, the subsequent check in the dry-run section may not handle this correctly. Consider explicitly checking for integers greater than or equal to 0 to make the intent clearer.

+    except Exception as e:
+        logger.warning(f"Failed to check existing profiles: {str(e)}")


[nitpick] The exception handling catches a generic Exception, which is overly broad. Consider catching specific exceptions like ResourceNotFoundError or HttpResponseError from Azure SDK to provide more targeted error handling and avoid masking unexpected errors.

+
+    try:
+        existing_app = ContainerAppClient.show(cmd, resource_group_name=resource_group_name, name=app_name)


The code uses from ._clients import ContainerAppClient but this import appears inside a function. If ContainerAppClient is not available in the module scope at line 1875, this will cause an import error. Consider importing at the module level or handling the import error appropriately.
