feat: azure provider improvements + trafficmanager + misc additions #675
Conversation
WalkthroughThe changes include the addition of a new dependency to support a refined goroutine pool implementation. The Azure provider now supports Traffic Manager resource management and verification with corresponding updates in the existing provider code, along with a new file implementing the Traffic Manager provider. In addition, the VM provider has been refactored to improve its resource fetching logic by introducing a helper function and switching to the new pond concurrency library. Changes

23-44: GetResource implementation for Traffic Manager profilesThe method correctly creates a new Resources object, fetches profiles, and processes them into schema.Resource objects with appropriate DNS name information.
I suggest adding a check for empty profiles list to potentially avoid unnecessary iteration.
func (tmp *trafficManagerProvider) GetResource(ctx context.Context) (*schema.Resources, error) { list := schema.NewResources() profiles, err := tmp.fetchTrafficManagerProfiles(ctx) if err != nil { return nil, err } + + if profiles == nil || len(*profiles) == 0 { + return list, nil + } for _, profile := range *profiles {

187-187: New dependency added for concurrent processingThe addition of
github.com/alitto/pond/v2introduces a goroutine pool library that simplifies concurrency management. This is a good choice as it will be used to refactor the VM provider's resource fetching logic.pkg/providers/azure/azure.go (5)
11-11: Import for Traffic Manager functionality addedAppropriate import added for the new Traffic Manager integration.
29-29: Service list updated to include Traffic ManagerThe Services variable is correctly updated to include the new "trafficmanager" service.
180-188: Traffic Manager resource processing addedThis code block properly integrates Traffic Manager resource retrieval into the existing resource processing flow, with appropriate error handling consistent with other service types.
202-204: Traffic Manager client initialization addedAppropriate client initialization for traffic manager verification.
219-224: Traffic Manager verification check addedThe verification logic for Traffic Manager profiles is consistent with the existing pattern used for other services, maintaining the conditional logic flow correctly.

11-16: Traffic Manager provider structure is well-definedThe provider struct contains the necessary fields (id, SubscriptionID, Authorizer) to interact with Azure's Traffic Manager API.
18-21: Provider name method implemented correctlySimple and consistent with other providers in the codebase.
46-57:Details
❓ Verification inconclusive
Traffic Manager profile fetching implementation
The method correctly creates a client, sets the authorizer, and retrieves profiles.
One potential improvement would be to handle pagination if the API supports it, as
ListBySubscriptionmight return a limited number of items per page.
🏁 Script executed:
#!/bin/bash # Verify if the Azure SDK's ListBySubscription method supports pagination # Search for method signature or any references to pagination in ListBySubscription rg --no-heading -A 3 'ListBySubscription' | grep -i 'page\|pagination\|iterator'Length of output: 80
Verify Pagination Handling in Traffic Manager Profile Fetching
The current implementation retrieves the profiles by directly returning
profilesIt.Valuewithout any explicit pagination handling. The preliminary search for pagination-related keywords (e.g., "page", "pagination", "iterator") in the context ofListBySubscriptiondid not yield any results. However, it remains unclear whether the Azure SDK’sListBySubscriptionalready abstracts the pagination or if additional logic (such as iterating over multiple pages) is required.
- File:
pkg/providers/azure/trafficmanager.goat lines 46-57- Issue: The code does not perform explicit pagination but may need to if the API returns paged results.
- Action: Please manually verify against the Azure SDK documentation or additional parts of the codebase to confirm if
ListBySubscriptionrequires the implementation of pagination handling.pkg/providers/azure/vm.go (7)
12-12: Library switch from ants to pond for concurrency managementThe imports have been updated to use the pond library for goroutine pool management and to include gologger for direct error logging. This is aligned with the change in go.mod.
Also applies to: 15-15
34-34: Improved function signature for fetchResouceGroupsThe function now accepts direct parameters (subscriptionID, authorizer) instead of the entire provider struct, which is a better practice for modularity and testability.
41-42: Simplified goroutine pool creation with pondSwitched from ants to pond library for the goroutine pool. The implementation is cleaner with a fixed pool size of 10, which should be appropriate for Azure API limitations.
47-58: Improved error handling in goroutine submissionsErrors during resource group processing are now properly logged directly using gologger instead of collecting them in an error slice. The code also has better resource management for the results.
60-60: Proper pool cleanup with StopAndWaitThe pool is correctly closed with StopAndWait(), ensuring all tasks complete before the method returns.
65-136: New helper method for processing resource groupsThe extracted processResourceGroup method improves code modularity and readability by encapsulating the complex logic for VM resource processing. It correctly:
- Fetches VM list
- Processes network interfaces
- Retrieves IP configurations
- Gets public IPs
- Creates and returns resource objects
This refactoring makes the code more maintainable and easier to test individually.
138-151: Updated fetchResouceGroups function signatureThe function now accepts direct parameters instead of a provider instance, which is more modular and follows better function design practices. The implementation remains functionally the same, maintaining compatibility with existing code.
