feat: real backends for Argo Workflows, K8s IAM, and environment connectivity by intel352 · Pull Request #177 · GoCodeAlone/workflow

intel352 · 2026-02-26T21:32:54Z

Summary

Argo Workflows: Real backend using Argo Server REST API (port 2746). Supports submit, status, logs, delete, list workflows. No new dependencies (stdlib net/http).
Kubernetes IAM Provider: Real implementation using K8s REST API with automatic in-cluster detection. Resolves ServiceAccount identities and tests cluster connectivity.
Environment Connection Test: Replaced placeholder with real HTTP connectivity check returning actual latency.
Multi-region: Improved error messages for unsupported providers with guidance on which modules to use instead.
DigitalOcean: Already had real godo implementations (no changes needed).

+		reqBody = bytes.NewReader(data)
+	}
+
+	req, err := http.NewRequestWithContext(ctx, method, b.endpoint+path, reqBody)


The Argo endpoint URL is directly concatenated with user-provided path without validation. This could enable Server-Side Request Forgery (SSRF) attacks if the endpoint is user-controlled or if path manipulation is possible. Consider validating that the constructed URL maintains the same scheme and host as the configured endpoint, similar to the pattern used in HTTPIntegrationConnector (module/integration.go:47-77).

+	// Check if Argo Server is reachable by calling the version endpoint.
+	_, status, err := b.doRequest(context.Background(), http.MethodGet, "/api/v1/version", nil)


The real backend methods use context.Background() for HTTP requests, ignoring the calling context. This prevents timeout propagation, cancellation signals, and tracing context from flowing through. Consider accepting a context parameter in backend interface methods or using the module's context if available.

+		if exists {

+				Provider:   string(store.IAMProviderKubernetes),
+				Identifier: fmt.Sprintf("system:serviceaccount:%s:%s", ns, sa),


The ServiceAccount identifier format has changed from "sa:my-svc" to "system:serviceaccount:namespace:name" which breaks the existing test expectations in iam/providers_test.go:131-132. This is a breaking change to the API contract that will cause test failures.

Suggested change

Identifier: fmt.Sprintf("system:serviceaccount:%s:%s", ns, sa),

Identifier: "sa:" + sa,

+			// Log but don't fail — fall back to accepting the credential as-is.
+			_ = err
+			exists = true


The error during ServiceAccount lookup is silently discarded and treated as if the SA exists. This means network errors, permission issues, or configuration problems will be hidden, potentially allowing unauthorized access. Consider either failing the request or logging the error with appropriate context.

return nil, fmt.Errorf("failed to look up service account %s/%s in cluster %s: %w", ns, sa, c.ClusterName, err)

The environment connectivity test performs an unauthenticated HTTP GET request to arbitrary user-configured endpoints without any SSRF protection. This allows internal network scanning and potential access to cloud metadata services (169.254.169.254). Consider validating URLs to prevent requests to private IP ranges, similar to the validateURL function in module/integration.go:48-77.

+			Latency: latency,
+		}
+	}
+	resp.Body.Close()


The HTTP response body is closed without reading its contents first, which can prevent HTTP connection reuse in the connection pool. Consider reading and discarding the body before closing, or use io.Copy to /dev/null for better connection pooling performance.

+			decoded = []byte(c.CAData)
+		}
+		caPool = x509.NewCertPool()
+		caPool.AppendCertsFromPEM(decoded)


The CA certificate data handling attempts base64 decoding but silently falls back to treating the input as raw PEM on decode error. This could mask configuration errors where base64-encoded data is malformed. Consider logging a warning or being explicit about which formats are accepted in the documentation.

 }


The new Kubernetes IAM provider functionality (API calls, in-cluster detection, TLS configuration) lacks test coverage. The existing tests in providers_test.go only validate configuration and basic stub behavior. Consider adding tests that verify the buildHTTPClient logic, in-cluster fallback, and serviceAccountExists behavior using httptest.Server.

The new real backend implementation lacks test coverage. All existing tests in argo_workflows_test.go only test the mock backend. Consider adding tests for the real backend that verify HTTP request construction, error handling, and response parsing without requiring an actual Argo server (use httptest.Server for mocking).

The connectivity test implementation lacks test coverage for the new real HTTP connectivity check behavior. The existing test at handler_test.go:130-145 will continue to pass because it doesn't set an endpoint in the config, but it won't validate the actual HTTP request logic. Consider adding a test that sets a valid endpoint and uses httptest.Server to verify the connectivity check.

+	ns := m.namespace()
+	path := fmt.Sprintf("/api/v1/workflows/%s", ns)
+	if labelSelector != "" {
+		path += "?listOptions.labelSelector=" + labelSelector


The labelSelector parameter is not URL-encoded before being concatenated into the query string. If a label selector contains special characters (e.g., "app=workflow,env=prod"), this could result in malformed URLs or incorrect API requests. Consider using url.QueryEscape to properly encode the labelSelector value before appending it to the path.

+		m.backend = &argoRealBackend{
+			endpoint:   endpoint,
+			token:      token,
+			httpClient: &http.Client{Timeout: 30 * time.Second},


The HTTP client is hard-coded in the argoRealBackend struct without the ability to inject a custom client for testing. This makes it difficult to write unit tests that don't depend on an actual Argo Server. Following the testing pattern seen in pipeline steps (e.g., pipeline_step_build_from_config.go), consider exposing httpClient as a field in argoRealBackend that can be set during tests to enable deterministic testing without running real HTTP requests.

The HTTP client is constructed locally within buildHTTPClient without the ability to inject it for testing. Following the pattern seen in iam/oidc.go where HTTPClient is exposed as an injectable field, consider making the HTTP client injectable at the provider level to enable deterministic unit tests. This would allow tests to use httptest.NewServer to verify API interactions without requiring actual Kubernetes cluster access.

The HTTP client is constructed inline without the ability to inject it for testing. Following testing patterns seen elsewhere in the codebase where HTTP clients are injected, consider making the HTTP client injectable (e.g., as a field in the Handler struct) to enable unit tests that use httptest.NewServer to verify connectivity test logic without making actual network requests.
