This addresses issue #112 where users previously could not know the start and end times for each canary batch. + +## Changes Made + +### 1. API Changes + +#### BatchReleaseCanaryStatus (v1alpha1 and v1beta1) +Added `BatchStartTime` field to track when each batch starts processing: + +```go +type BatchReleaseCanaryStatus struct { + // ... existing fields ... + + // BatchStartTime is the start timestamp of the current batch. + // This field is updated when a batch starts processing. + // +optional + BatchStartTime *metav1.Time `json:"batchStartTime,omitempty"` + + // BatchReadyTime is the ready timestamp of the current batch or the last batch. + // This field is updated once a batch ready, and the batches[x].pausedSeconds + // relies on this field to calculate the real-time duration. + BatchReadyTime *metav1.Time `json:"batchReadyTime,omitempty"` + + // ... other fields ... +} +``` + +#### Rollout CanaryStatus (v1beta1) +Added timing fields to track step timing information: + +```go +type CanaryStatus struct { + // ... existing fields ... + + // CurrentStepStartTime is the start timestamp of the current canary step/batch. + // This field is updated when a step starts processing. + // +optional + CurrentStepStartTime *metav1.Time `json:"currentStepStartTime,omitempty"` + + // CurrentStepEndTime is the end timestamp of the current canary step/batch. + // This field is updated when a step completes. + // +optional + CurrentStepEndTime *metav1.Time `json:"currentStepEndTime,omitempty"` + + // ... other fields ... +} +``` + +### 2. Controller Logic Changes + +#### BatchRelease Executor +- **Setting Start Time**: `BatchStartTime` is set when a batch first enters `UpgradingBatchState` +- **Resetting Start Time**: `BatchStartTime` is reset to `nil` when: + - Moving to the next batch + - Restarting a batch + - Recalculating due to plan changes + +#### Rollout Controller +- **Syncing Timing**: The `syncBatchRelease` function now syncs timing information from `BatchRelease` to `Rollout` status +- **Status Updates**: `CurrentStepStartTime` and `CurrentStepEndTime` are updated based on the corresponding `BatchRelease` timing + +### 3. Conversion Functions +Updated conversion functions in `api/v1alpha1/conversion.go` to properly handle the new `BatchStartTime` field when converting between API versions. + +## Usage + +### Viewing Timing Information + +You can now view timing information for canary batches: + +```bash +# View BatchRelease timing +kubectl get batchrelease -o yaml + +# View Rollout timing +kubectl get rollout -o yaml +``` + +### Example Output + +```yaml +status: + canaryStatus: + currentBatch: 1 + batchState: "UpgradingBatchState" + batchStartTime: "2023-01-06T10:30:00Z" + batchReadyTime: "2023-01-06T10:35:00Z" + updatedReplicas: 2 + updatedReadyReplicas: 2 +``` + +## Benefits + +1. **Visibility**: Users can now track how long each canary batch takes to complete +2. **Monitoring**: Enables better monitoring and alerting based on batch timing +3. **Debugging**: Helps identify performance issues or bottlenecks in specific batches +4. **Compliance**: Provides audit trail for deployment timing + +## Backward Compatibility + +- The new fields are optional (`+optional` tag) +- Existing Rollouts and BatchReleases will continue to work without the new timing fields +- The fields will be populated for new deployments or when existing resources are updated + +## Testing + +The feature has been tested with: +- Unit tests for the batchrelease controller +- API validation and conversion tests +- Build verification to ensure no compilation errors + +## Related Issues + +- Fixes #112: [Feature] need record the starttime and endtime for every canary batch in Rollout diff
