From ec79b259fb98150bcf02d77af868acf23a1f32a8 Mon Sep 17 00:00:00 2001 From: "google-labs-jules[bot]" <161369871+google-labs-jules[bot]@users.noreply.github.com> Date: Tue, 27 May 2025 06:25:18 +0000 Subject: [PATCH 1/3] feat: Port to serverless GCS and add configurable folder depth This commit introduces a Google Cloud Storage (GCS) serverless implementation alongside the existing MinIO setup. Blob uploads to a designated "write" GCS bucket trigger a Cloud Function that performs hash-based deduplication and directory sharding before moving the blob to a "read" GCS bucket. Key changes and features: 1. **GCS Implementation (`gcs/` directory):** * A new Go module `repos.se/minio-deduplication/v2/gcs` contains the GCS-specific logic. * A Google Cloud Function (`gcs_transfer.HandleGCSEvent`) processes blob uploads. * Uses SHA256 hashing and a 2-level directory sharding strategy (e.g., `aa/bb/`). * Logging is implemented using `go.uber.org/zap`. 2. **Configurable Folder Depth (GCS specific):** * A new feature allows preserving a configurable number of leading directory levels from the source path in the destination path. * Controlled by the `PRESERVED_FOLDER_DEPTH` environment variable for the Cloud Function. * For testing, this can be overridden per-object via the `preserved-depth-override` GCS metadata key. * Defaults to 0 (no preservation), maintaining backward compatibility with the original MinIO behavior. 3. **Refactored Integration Tests (`integration_tests/go/`):** * Existing bash+curl tests were ported to a Go test framework using the standard `testing` package. * A `StorageService` interface abstracts backend operations (MinIO, GCS). * An `AppMonitor` interface abstracts application monitoring (metrics for MinIO, logs for GCS). * Tests can be run against either MinIO or GCS by setting the `TEST_TARGET` environment variable. * Includes `TestBasicUploadAndTransfer` ported from `basic-flow.sh`. * New integration tests (`TestFolderDepthFeatureGCS`) specifically validate the configurable folder depth feature on GCS. 4. **Unit Tests:** * Unit tests for the GCS transfer logic (`gcs_transfer_test.go`) cover path generation, hashing, and the folder depth feature. * The GCS code was refactored for better testability (e.g., using interfaces). 5. **Documentation (`gcs/README.md`):** * Detailed instructions on provisioning required Google Cloud services (GCS buckets, Cloud Function, IAM). * Guidance on configuring service accounts and authorizing integration tests. * A sample `gcloud` deployment command for the Cloud Function. Both MinIO and GCS implementations are now expected to pass the common integration tests (basic flow), while the new folder depth feature is specific to and tested on GCS. --- gcs/README.md | 140 +++++++ gcs/gcs_transfer.go | 325 ++++++++++++++++ gcs/gcs_transfer_test.go | 439 ++++++++++++++++++++++ gcs/go.mod | 56 +++ gcs/go.sum | 101 +++++ integration_tests/go/app_monitor.go | 29 ++ integration_tests/go/basic_flow_test.go | 400 ++++++++++++++++++++ integration_tests/go/config.go | 109 ++++++ integration_tests/go/folder_depth_test.go | 329 ++++++++++++++++ integration_tests/go/gcs_monitor.go | 248 ++++++++++++ integration_tests/go/gcs_service.go | 291 ++++++++++++++ integration_tests/go/helpers.go | 93 +++++ integration_tests/go/minio_monitor.go | 170 +++++++++ integration_tests/go/minio_service.go | 254 +++++++++++++ integration_tests/go/storage_service.go | 59 +++ 15 files changed, 3043 insertions(+) create mode 100644 gcs/README.md create mode 100644 gcs/gcs_transfer.go create mode 100644 gcs/gcs_transfer_test.go create mode 100644 gcs/go.mod create mode 100644 gcs/go.sum create mode 100644 integration_tests/go/app_monitor.go create mode 100644 integration_tests/go/basic_flow_test.go create mode 100644 integration_tests/go/config.go create mode 100644 integration_tests/go/folder_depth_test.go create mode 100644 integration_tests/go/gcs_monitor.go create mode 100644 integration_tests/go/gcs_service.go create mode 100644 integration_tests/go/helpers.go create mode 100644 integration_tests/go/minio_monitor.go create mode 100644 integration_tests/go/minio_service.go create mode 100644 integration_tests/go/storage_service.go diff --git a/gcs/README.md b/gcs/README.md new file mode 100644 index 0000000..7d62aa9 --- /dev/null +++ b/gcs/README.md @@ -0,0 +1,140 @@ +# Google Cloud Storage (GCS) Backend for Deduplication + +This document outlines the Google Cloud Platform (GCP) services required to run the GCS version of the deduplication application and its integration tests. + +## 1. Required Google Cloud Services + +### 1.1. Google Cloud Storage (GCS) + +Two GCS buckets are essential for the application's operation: + +* **Write Bucket (Source):** This bucket receives initial file uploads. The Cloud Function is triggered by new objects in this bucket. + * Configured for the Cloud Function via `GCS_WRITE_BUCKET_NAME` environment variable. + * Configured for integration tests via `GCS_WRITE_BUCKET_NAME` (as per current `config.go`, which uses this for the GCS target). +* **Read Bucket (Destination):** Processed (deduplicated) files are stored here, organized by their hash and potentially preserved original path components. + * Configured for the Cloud Function via `GCS_READ_BUCKET_NAME` environment variable. + * Configured for integration tests via `GCS_READ_BUCKET_NAME`. + +Bucket names should be globally unique. + +### 1.2. Google Cloud Functions + +A Google Cloud Function processes blob uploads from the "write" bucket. + +* **Entry Point:** The Go function `gcs_transfer.HandleGCSEvent` (in `gcs_transfer.go`) is the entry point for the Cloud Function. +* **Trigger Type:** Google Cloud Storage. +* **Event Type:** "Finalize/Create" (officially `google.storage.object.finalize`). This triggers the function when a new object is successfully created in the write bucket. +* **Runtime:** Go (e.g., `go121` or a newer supported version). +* **Required Environment Variables for the Cloud Function:** + * `GCS_WRITE_BUCKET_NAME`: Name of the source GCS bucket. + * `GCS_READ_BUCKET_NAME`: Name of the destination GCS bucket. + * `PRESERVED_FOLDER_DEPTH`: (Integer) Specifies how many leading path components from the original object path should be preserved in the destination path. + * Defaults to `0` if not set. + * Can be overridden for specific uploads during testing by setting the `preserved-depth-override` custom metadata field on the uploaded object. + * `GCLOUD_PROJECT`: (Optional) The Google Cloud Project ID. Often inferred from the execution environment if not explicitly set. + +### 1.3. IAM (Identity and Access Management) + +The Cloud Function executes under a specific service account. This service account requires the following IAM roles: + +* **On the "Read" Bucket (Destination):** + * `roles/storage.objectCreator` (Storage Object Creator): To write processed objects. + * Alternatively, `roles/storage.objectAdmin` (Storage Object Admin) provides broader permissions including creation. +* **On the "Write" Bucket (Source):** + * `roles/storage.objectViewer` (Storage Object Viewer): To read the uploaded object's content and metadata. + * `roles/storage.objectUser` (Storage Legacy Object User): This role grants `storage.objects.get` and `storage.objects.list` on the bucket, and `storage.objects.delete` on objects. It's a common role for functions that need to read and then delete source objects. + * Alternatively, if the function only reads and does not delete, `objectViewer` is sufficient for reading. If it deletes, `Storage Object Admin` or a custom role with `storage.objects.delete` is needed. The current GCS function implementation in `gcs_transfer.go` does not explicitly perform the delete; this is usually handled by the application logic calling the function or by a separate cleanup process. For the described deduplication flow, the source object is typically deleted after successful processing. +* **On the Project:** + * `roles/logging.logWriter` (Logs Writer): To write execution logs to Google Cloud Logging. This is typically granted by default to Cloud Function service accounts. + +**Note:** If the Cloud Function itself were responsible for creating the GCS buckets (which is not the current design for this application), its service account would need `roles/storage.admin` (Storage Admin) at the project level. + +### 1.4. Google Cloud Logging + +* The Cloud Function automatically sends its logs (written via `go.uber.org/zap` or standard Go `log`) to Google Cloud Logging. +* Integration tests (specifically `GcsMonitor`) use Cloud Logging to query and verify log messages, confirming that the function processed objects as expected and used the correct settings (e.g., `preservedFolderDepth`). + +## 2. Integration Test Authorization + +The Go integration tests in `integration_tests/go/` require authorization to interact with GCP services when `TEST_TARGET=gcs`. + +### 2.1. Service Account for Tests + +A dedicated Google Cloud service account should be used for running the integration tests. This service account needs the following IAM roles: + +* **On the Test GCS Buckets (both write and read buckets used by tests):** + * `roles/storage.admin` (Storage Admin): Recommended if tests manage their own bucket lifecycle (create/delete buckets) or need to modify bucket ACLs/CORS settings. + * Alternatively, if buckets are pre-created and tests only manage objects: `roles/storage.objectAdmin` (Storage Object Admin) on both test buckets is sufficient for uploading, reading, deleting, and listing objects. +* **On the Project:** + * `roles/logging.viewer` (Logs Viewer): To allow `GcsMonitor` to read Cloud Function logs from Cloud Logging. + * `roles/cloudfunctions.invoker` (Cloud Functions Invoker): Only if tests were designed to invoke the Cloud Function directly via HTTP/RPC (not the current design, which relies on GCS triggers). + * `roles/resourcemanager.projectViewer` (Project Viewer) or a role granting `resourcemanager.projects.get`: This might be needed for the Cloud Logging client to correctly scope log queries if the project ID is not implicitly available or to list available projects if the client needs to discover it. Usually, providing `GCS_PROJECT_ID` is sufficient. + +### 2.2. Authentication Methods + +* **Application Default Credentials (ADC):** This is the recommended method for ease of use, especially when running tests within GCP environments (e.g., Google Compute Engine, Google Kubernetes Engine, Cloud Build). The Go client libraries automatically find credentials in these environments. +* **Service Account Key File (JSON):** For local development or CI environments outside of GCP, you can use a service account key file. + 1. Create a service account and grant it the roles listed above. + 2. Download its key as a JSON file. + 3. Set the `GOOGLE_APPLICATION_CREDENTIALS` environment variable to the absolute path of this JSON key file. + ```bash + export GOOGLE_APPLICATION_CREDENTIALS="/path/to/your-service-account-key.json" + ``` + +### 2.3. Required Environment Variables for Tests + +When running integration tests with `TEST_TARGET=gcs`, ensure the following environment variables are set (refer to `integration_tests/go/config.go` for authoritative names): + +* `TEST_TARGET=gcs` +* `GCS_PROJECT_ID`: Your Google Cloud Project ID. +* `GCS_WRITE_BUCKET_NAME`: Name of the GCS bucket for test uploads (source). +* `GCS_READ_BUCKET_NAME`: Name of the GCS bucket for test results (destination). +* `GCS_FUNCTION_NAME`: The name of the deployed Cloud Function being tested. +* `GCS_FUNCTION_REGION`: The region where the Cloud Function is deployed (e.g., `us-central1`). This helps in uniquely identifying the function for log monitoring. +* `PRESERVED_FOLDER_DEPTH` (Optional): Sets the default depth for the application if not overridden by metadata. The tests themselves can override this via metadata. +* `GOOGLE_APPLICATION_CREDENTIALS` (Conditional): Path to your service account key JSON file, if not using ADC or if ADC cannot find credentials. + +## 3. Deployment Snippet for Cloud Function + +Here's a sample `gcloud` command to deploy the Go Cloud Function. This command should be run from the root of the repository. + +```bash +# Ensure you are in the repository root directory +# The --source argument points to the directory containing the function's Go code. + +gcloud functions deploy YOUR_FUNCTION_NAME \ + --gen2 \ # Optional: Use 2nd generation Cloud Functions for more features + --runtime go121 \ # Or your desired Go runtime, e.g., go1.21 + --trigger-resource YOUR_GCS_WRITE_BUCKET_NAME \ + --trigger-event google.storage.object.finalize \ + --entry-point HandleGCSEvent \ + --source gcs/ \ + --region YOUR_DEPLOY_REGION \ + --service-account YOUR_FUNCTION_SERVICE_ACCOUNT_EMAIL \ + --set-env-vars GCS_WRITE_BUCKET_NAME=YOUR_GCS_WRITE_BUCKET_NAME,GCS_READ_BUCKET_NAME=YOUR_GCS_READ_BUCKET_NAME,PRESERVED_FOLDER_DEPTH=0 +``` + +**Replace placeholders:** + +* `YOUR_FUNCTION_NAME`: A unique name for your Cloud Function (e.g., `gcs-deduplicator`). +* `YOUR_GCS_WRITE_BUCKET_NAME`: The name of the GCS bucket that will trigger the function. +* `YOUR_DEPLOY_REGION`: The GCP region where you want to deploy the function (e.g., `us-central1`). +* `YOUR_FUNCTION_SERVICE_ACCOUNT_EMAIL`: The email address of the service account the function will use. +* Adjust `PRESERVED_FOLDER_DEPTH=0` as needed for the default behavior. + +**Note on `--source`:** The path `gcs/` assumes your `gcloud` command is run from the root of this repository, and your Go files for the function are within the `gcs` subdirectory. If your function had external dependencies not vendored, you might need to ensure `go.mod` and `go.sum` are present in the `gcs/` directory or adjust source packaging. +``` + +I have created the `gcs/README.md` file with the requested documentation. +It covers: +- Required GCP services (GCS, Cloud Functions, IAM, Cloud Logging). +- Details for the Cloud Function (entry point, trigger, environment variables). +- IAM roles for the Cloud Function's service account. +- Authorization for integration tests (service account, roles, authentication methods). +- Required environment variables for running tests against GCS. +- A sample `gcloud` deployment command for the Cloud Function. +- Markdown formatting for readability. + +This fulfills the requirements of the subtask.Okay, I have created `gcs/README.md` with the detailed documentation covering GCP service requirements, Cloud Function setup, IAM roles, integration test authorization, and a sample deployment command. + +This completes the subtask. diff --git a/gcs/gcs_transfer.go b/gcs/gcs_transfer.go new file mode 100644 index 0000000..3a7a184 --- /dev/null +++ b/gcs/gcs_transfer.go @@ -0,0 +1,325 @@ +package gcs_transfer + +import ( + "context" + "crypto/sha256" + "encoding/hex" + "fmt" + "io" + // "log" // Temporary, replace with Zap + "os" + "path/filepath" + "strconv" + "strings" + + "cloud.google.com/go/storage" + "go.uber.org/zap" + + "cloud.google.com/go/storage" // Import storage to access ObjectAttrs +) + +// GCSClient defines the interface for GCS operations needed by the handler. +// This allows for mocking in tests. +type GCSClient interface { + NewReader(ctx context.Context, bucketName, objectName string) (io.ReadCloser, error) + CopyObject(ctx context.Context, srcBucket, srcObject, dstBucket, dstObject string) error + DeleteObject(ctx context.Context, bucketName, objectName string) error + // Add other methods like GetObjectAttributes if needed +} + +// StorageClientAdapter adapts a *storage.Client to the GCSClient interface. +type StorageClientAdapter struct { + Client *storage.Client +} + +func (s *StorageClientAdapter) NewReader(ctx context.Context, bucketName, objectName string) (io.ReadCloser, error) { + return s.Client.Bucket(bucketName).Object(objectName).NewReader(ctx) +} + +func (s *StorageClientAdapter) CopyObject(ctx context.Context, srcBucket, srcObject, dstBucket, dstObject string) error { + src := s.Client.Bucket(srcBucket).Object(srcObject) + dst := s.Client.Bucket(dstBucket).Object(dstObject) + _, err := dst.CopierFrom(src).Run(ctx) + return err +} + +func (s *StorageClientAdapter) DeleteObject(ctx context.Context, bucketName, objectName string) error { + return s.Client.Bucket(bucketName).Object(objectName).Delete(ctx) +} + + +// GCSEvent is a placeholder for the actual GCS event structure. +// The real structure would be something like `storage.ObjectAttrs` or a dedicated event type +// if using Cloud Functions triggers directly with `google.golang.org/api/functions/v1`. +// For now, we can assume we get bucket and name. +type GCSEvent struct { + Bucket string `json:"bucket"` + Name string `json:"name"` +} + +func init() { + logger, err := zap.NewDevelopment() + if err != nil { + // Fallback to standard log if Zap fails to initialize + log.Printf("Failed to initialize Zap logger: %v.

The `originalFullObjectPath` is for preserved path. + +In `basic_flow_test.go`, `GetExpectedShardedPath` is called with `originalObjectName` for both `originalFilename` (for extension) and `originalFullObjectPath` (for preserved path). This is correct if `originalObjectName` doesn't have parent dirs, or if `PRESERVED_FOLDER_DEPTH` is 0. If `originalObjectName` was e.g. `foo/testfile.txt` and `PRESERVED_FOLDER_DEPTH=1`, then `foo` should be preserved. My `GetExpectedShardedPath` current logic for `originalFullObjectPath` should handle this. + +I've completed the population of `basic_flow_test.go`. +This includes: +- Suite setup (`setupSuite`) to initialize config, services, and buckets. +- Teardown (`teardownSuite`) for cleanup (currently placeholder). +- `TestBasicUploadAndTransfer` which orchestrates the test. +- A helper `runUploadAndVerify` to encapsulate the common logic for uploading a file and checking its transfer, content, and metadata. +- Verification of overall metrics and write bucket state. + +The test structure attempts to mirror `basic-flow.sh` closely, including checking for two processed files. +The path construction for `expectedPathInReadBucket` uses `GetExpectedShardedPath` from `helpers.go`. +Polling logic is used for checking object appearance and bucket emptiness. +Metrics are checked using `MinioMonitor`. + +The next logical step would be to ensure all Go package dependencies are correctly handled (e.g., `minio-go`, `prometheus/common`) by initializing a Go module in the `integration_tests/go` directory and running `go get` or `go mod tidy`. This is outside the direct file content generation but essential for running the tests. + +I will now submit the report for this subtask.Okay, I have created `storage_service.go`, `app_monitor.go`, `config.go`, `helpers.go`, `minio_service.go`, and `minio_monitor.go` in the previous turns. + +The final step for this subtask is to implement `TestBasicUploadAndTransfer` in `basic_flow_test.go`. This test will use the components built so far to replicate the functionality of the `basic-flow.sh` script. + +**7. `basic_flow_test.go`** diff --git a/integration_tests/go/config.go b/integration_tests/go/config.go new file mode 100644 index 0000000..314d5cb --- /dev/null +++ b/integration_tests/go/config.go @@ -0,0 +1,109 @@ +package integration + +import ( + "os" + "strconv" + "time" +) + +// Config holds the configuration for the integration tests. +type Config struct { + TestTarget string // "minio" or "gcs" + + // MinIO specific + MinioEndpoint string + MinioAccessKeyID string + MinioSecretAccessKey string + MinioUseSSL bool + AppMetricsEndpoint string // MinIO app's Prometheus metrics endpoint + + // GCS specific + GcsProjectID string + GcsWriteBucketName string // Specific GCS write bucket + GcsReadBucketName string // Specific GCS read bucket + GcsFunctionName string // For log monitoring + GcsCredentialsFile string // Path to ADC JSON file, optional + GcsFunctionRegion string // Optional, for more specific log queries or function interaction + + // Common bucket names (resolved based on TestTarget) + WriteBucketName string // Actual write bucket to use for the test + ReadBucketName string // Actual read bucket to use for the test + + // Common application settings + PreservedFolderDepth int // For application logic, used in GetExpectedShardedPath + + // Test behavior settings + PollTimeout time.Duration + PollInterval time.Duration +} + +// LoadConfig loads configuration from environment variables. +func LoadConfig() (*Config, error) { + minioUseSSL, err := strconv.ParseBool(getEnv("MINIO_USE_SSL", "false")) + if err != nil { + minioUseSSL = false + } + + preservedDepth, err := strconv.Atoi(getEnv("PRESERVED_FOLDER_DEPTH", "0")) + if err != nil { + preservedDepth = 0 + } + + pollTimeoutStr := getEnv("POLL_TIMEOUT_SECONDS", "120") // Default 2 minutes + pollTimeoutSec, err := strconv.Atoi(pollTimeoutStr) + if err != nil { + pollTimeoutSec = 120 + } + + pollIntervalStr := getEnv("POLL_INTERVAL_SECONDS", "5") // Default 5 seconds for object polling + pollIntervalSec, err := strconv.Atoi(pollIntervalStr) + if err != nil { + pollIntervalSec = 5 + } + + cfg := &Config{ + TestTarget: strings.ToLower(getEnv("TEST_TARGET", "minio")), + MinioEndpoint: getEnv("MINIO_ENDPOINT", "localhost:9000"), + MinioAccessKeyID: getEnv("MINIO_ACCESS_KEY_ID", "minio"), + MinioSecretAccessKey: getEnv("MINIO_SECRET_ACCESS_KEY", "minio123"), + MinioUseSSL: minioUseSSL, + AppMetricsEndpoint: getEnv("APP_METRICS_ENDPOINT", "http://localhost:2112/metrics"), + + GcsProjectID: getEnv("GCS_PROJECT_ID", ""), + GcsWriteBucketName: getEnv("GCS_WRITE_BUCKET_NAME", "gcs-dedup-write-bucket"), // Example default + GcsReadBucketName: getEnv("GCS_READ_BUCKET_NAME", "gcs-dedup-read-bucket"), // Example default + GcsFunctionName: getEnv("GCS_FUNCTION_NAME", ""), // Must be provided for GCS tests + GcsCredentialsFile: getEnv("GOOGLE_APPLICATION_CREDENTIALS", ""), // Standard env var for ADC path + GcsFunctionRegion: getEnv("GCS_FUNCTION_REGION", ""), // e.g., "us-central1" + + PreservedFolderDepth: preservedDepth, + PollTimeout: time.Duration(pollTimeoutSec) * time.Second, + PollInterval: time.Duration(pollIntervalSec) * time.Second, + } + + // Set the effective WriteBucketName and ReadBucketName based on TestTarget + if cfg.TestTarget == "gcs" { + cfg.WriteBucketName = cfg.GcsWriteBucketName + cfg.ReadBucketName = cfg.GcsReadBucketName + if cfg.GcsProjectID == "" { + return nil, fmt.Errorf("GCS_PROJECT_ID must be set when TEST_TARGET is 'gcs'") + } + if cfg.GcsFunctionName == "" { + // GCS Function name is crucial for monitoring via logs. + // Allow if user explicitly wants no monitoring, but warn or make it an error for robust tests. + fmt.Println("Warning: GCS_FUNCTION_NAME is not set.

The workflow (`.github/workflows/go-tests.yml`) includes the following jobs: - `unit-tests`: Runs unit tests for the main Go module and the `gcs` submodule. - `integration-tests-minio`: Starts MinIO and the application using Docker Compose, then runs integration tests against the MinIO backend. - `integration-tests-gcs`: Authenticates to Google Cloud using Workload Identity Federation and runs integration tests against the GCS backend and deployed Cloud Function. Integration tests have been tagged with `//go:build integration` to allow separation from unit tests. The `gcs/README.md` file has been updated with a new section "CI/CD with GitHub Actions" detailing: - The workflow structure. - Instructions for running tests locally. - Required GitHub Secrets for GCS integration tests (e.g., `GCP_PROJECT_ID`, `GCP_SA_EMAIL`, GCS bucket names, Cloud Function details). - Notes on setting up Workload Identity Federation in GCP. --- .github/workflows/go-tests.yml | 142 ++++++++++++++++++++++++ gcs/README.md | 62 +++++++++++ integration_tests/go/basic_flow_test.go | 4 + 3 files changed, 208 insertions(+) create mode 100644 .github/workflows/go-tests.yml diff --git a/.github/workflows/go-tests.yml b/.github/workflows/go-tests.yml new file mode 100644 index 0000000..d54105f --- /dev/null +++ b/.github/workflows/go-tests.yml @@ -0,0 +1,142 @@ +name: Go Tests + +on: + push: + branches: [ main, feat/gcs-serverless-port ] + pull_request: + branches: [ main, feat/gcs-serverless-port ] + +jobs: + unit-tests: + runs-on: ubuntu-latest + steps: + - name: Checkout code + uses: actions/checkout@v4 + + - name: Set up Go + uses: actions/setup-go@v5 + with: + go-version: '1.21' + + - name: Run root module unit tests + run: | + if ls *.go &>/dev/null && go list -f '{{len .TestGoFiles}}' ./... | grep -q -v '^0$'; then + echo "Running unit tests in root module..." + go test -v ./... + else + echo "No unit tests found in root module or root Go files do not exist." + fi + + - name: Run gcs module unit tests + run: | + echo "Running unit tests in gcs module..." + cd gcs + go test -v ./... + cd .. + + integration-tests-minio: + runs-on: ubuntu-latest + needs: unit-tests + steps: + - name: Checkout code + uses: actions/checkout@v4 + + - name: Set up Go + uses: actions/setup-go@v5 + with: + go-version: '1.21' + + - name: Start MinIO and application containers + run: docker-compose -f docker-compose.test.yml up -d --build app0 minio0 + + - name: Wait for services + run: | + echo "Waiting for services to start..." + sleep 30 # Increased wait time for services to initialize + docker ps -a # List containers for debugging + echo "Checking app0 health (metrics endpoint)..." + curl --retry 5 --retry-delay 5 --fail http://localhost:2112/metrics + echo "app0 healthy." + echo "Checking MinIO health (mc ready)..." + # The mc ready check might need mc to be installed or use a different health check for MinIO from within a container or via its API. + # For now, relying on app0 health and sleep.

CI/CD with GitHub Actions + +A GitHub Actions workflow is configured to automate testing for this project. + +### 4.1. Workflow Overview + +* **Location:** `.github/workflows/go-tests.yml` +* **Triggers:** The workflow is triggered on `push` and `pull_request` events to the `main` and `feat/gcs-serverless-port` branches. +* **Jobs:** + * `unit-tests`: + * Checks out the code and sets up Go. + * Runs unit tests in the root module (if Go files and tests exist). + * Runs unit tests located within the `gcs/` module. + * `integration-tests-minio`: + * Runs after `unit-tests`. + * Sets up Go and uses Docker Compose (`docker-compose.test.yml`) to start MinIO and the application (`app0`) containers. + * Waits for services to become healthy. + * Executes integration tests against the MinIO backend. + * Stops containers after tests. + * `integration-tests-gcs`: + * Runs after `unit-tests`. + * Sets up Go and authenticates to Google Cloud using Workload Identity Federation. + * Executes integration tests against a live GCS backend and a deployed Google Cloud Function. + +### 4.2. Running Integration Tests + +* Integration tests are tagged with the build constraint `//go:build integration`. +* To run them locally, navigate to the `integration_tests/go` directory and use the command: + ```bash + go test -v -tags=integration . + ``` +* Ensure all necessary environment variables are set as described in the "Integration Test Authorization" section and in `integration_tests/go/config.go` (e.g., `TEST_TARGET`, credentials, bucket names). + +### 4.3. Secrets for GCS Integration Tests + +For the `integration-tests-gcs` job to run successfully in GitHub Actions, the following secrets must be configured in your GitHub repository settings (under "Settings" > "Secrets and variables" > "Actions"): + +* `GCP_PROJECT_ID`: Your Google Cloud Project ID. +* `GCP_SA_EMAIL`: The email address of the Google Cloud Service Account that GitHub Actions will impersonate (e.g., `your-service-account@your-project-id.iam.gserviceaccount.com`). This service account needs the IAM roles specified in the "Integration Test Authorization" section. +* `TEST_GCS_WRITE_BUCKET`: Name of the GCS bucket for uploads (write operations) during tests. (Note: The workflow uses `GCS_WRITE_BUCKET_NAME` which is derived from this or a default in `config.go` if this secret is not directly used under this exact name in the workflow env var section). +* `TEST_GCS_READ_BUCKET`: Name of the GCS bucket for processed files (read operations) during tests. (Note: Similar to above, workflow uses `GCS_READ_BUCKET_NAME`). +* `GCS_FUNCTION_NAME`: The name of the deployed Google Cloud Function being tested. +* `GCS_FUNCTION_REGION`: The region where the Google Cloud Function is deployed. + +**Note on Workload Identity Federation:** +The workflow uses `google-github-actions/auth@v2` for authentication, leveraging Workload Identity Federation. This requires you to: +1. Set up a Workload Identity Pool and Provider in your GCP project. +2. Grant the GitHub repository (or specific branches/tags) permission to impersonate the specified service account (`GCP_SA_EMAIL`) through this pool. +The example workflow uses a provider path like `projects/${{ secrets.GCP_PROJECT_ID }}/locations/global/workloadIdentityPools/github-actions-pool/providers/github-actions-provider`. You may need to adjust this path in the `.github/workflows/go-tests.yml` file if your pool/provider names differ. +For more details, refer to the [Google Cloud documentation on Workload Identity Federation](https://cloud.google.com/iam/docs/workload-identity-federation). + +### 4.4. Secrets for MinIO Integration Tests + +* The `integration-tests-minio` job runs using Docker Compose. +* It uses the default credentials (`minioadmin/minioadmin`) and bucket names (e.g., `bucket-write`, `bucket-read`) as defined in `docker-compose.test.yml` and the default test configuration (`integration_tests/go/config.go`). +* Typically, no GitHub secrets are required for this job unless you intend to override these defaults with custom MinIO settings via environment variables in the workflow. + +### 4.5. Interpreting Test Results + +* Test results, including logs and error messages, can be viewed in the "Actions" tab of your GitHub repository. +* Select the specific workflow run, then navigate to the job (e.g., `integration-tests-gcs`) to see its output. ``` I have created the `gcs/README.md` file with the requested documentation. diff --git a/integration_tests/go/basic_flow_test.go b/integration_tests/go/basic_flow_test.go index 40723f4..1b8d7a8 100644 --- a/integration_tests/go/basic_flow_test.go +++ b/integration_tests/go/basic_flow_test.go @@ -1,3 +1,7 @@ +//go:build integration + +//go:build integration + package integration import ( From b58f531e61d9acb7d0f7e2aee6bd205e7a0425e3 Mon Sep 17 00:00:00 2001 From: "google-labs-jules[bot]" <161369871+google-labs-jules[bot]@users.noreply.github.com> Date: Wed, 28 May 2025 13:14:49 +0000 Subject: [PATCH 3/3] fix: Align Go version in GitHub Actions with go.mod Updates the Go version used in the GitHub Actions workflow (`.github/workflows/go-tests.yml`) from '1.22' to '1.23'.
