CRD Schema Update (`src/types/v1alpha1/tenant.rs`) +- **New Fields**: Added `livenessProbe`, `readinessProbe`, and `startupProbe` to the `TenantSpec` struct. +- **Type**: These fields use the standard Kubernetes `corev1::Probe` type, allowing full customization (httpGet, exec, tcpSocket, thresholds, etc.). +- **Optional**: All fields are optional to maintain backward compatibility. + +### 2. Intelligent StatefulSet Generation (`src/types/v1alpha1/tenant/workloads.rs`) +- **Probe Injection**: The `new_statefulset` method now injects these probes into the RustFS container definition. +- **Smart Defaults**: To ensure out-of-the-box reliability, the operator applies optimized default values if the user does not specify custom probes: + - **Liveness Probe**: Checks `/rustfs/health/live` on port 9000. + - `initialDelaySeconds`: 120s (Gives ample time for initialization) + - `periodSeconds`: 15s + - **Readiness Probe**: Checks `/rustfs/health/ready` on port 9000. + - `initialDelaySeconds`: 30s + - `periodSeconds`: 10s + - **Startup Probe**: Checks `/rustfs/health/startup` on port 9000. + - `failureThreshold`: 30 (Allows up to 5 minutes for slow startups before killing the pod) + +### 3. Enhanced Reconciliation & Update Logic +- **Update Detection**: Updated `statefulset_needs_update` to include deep comparison of probe configurations. +- **Rolling Updates**: Changing probe settings in the Tenant CRD will now correctly trigger a rolling update of the StatefulSet, ensuring the new health check policies are applied. + +## ๐Ÿงช Testing Verification + +All tests passed successfully (`cargo test`). + +- **New Unit Tests**: + - `test_default_probes_applied`: Confirms that smart defaults are applied when CRD fields are missing. + - `test_custom_probes_override`: Confirms that user-provided configurations take precedence over defaults. + - `test_probe_update_detection`: Confirms that modifying probe parameters triggers a reconciliation update. +- **Regression Testing**: Verified that existing tests (RBAC, ServiceAccount, Labels, etc.) continue to pass. + +## ๐Ÿ“ฆ Impact + +- **Reliability**: Pods that deadlock or become unresponsive will now be automatically restarted by Kubernetes. +- **Availability**: Traffic will not be routed to pods that are not ready (e.g., during startup or temporary failure). +- **UX**: Users get production-ready defaults without needing complex configuration, but retain full control if needed. + +## โœ… Checklist + +- [x] Code compiles successfully. +- [x] `cargo fmt` has been run. +- [x] `cargo clippy` passes without errors. +- [x] New unit tests added and passing (43/43 tests passed). +- [x] Documentation (CRD fields) is self-explanatory. diff --git a/src/types/v1alpha1/tenant.rs b/src/types/v1alpha1/tenant.rs index 541e837..ce4664b 100644 --- a/src/types/v1alpha1/tenant.rs +++ b/src/types/v1alpha1/tenant.rs @@ -97,6 +97,15 @@ pub struct TenantSpec { #[serde(default, skip_serializing_if = "Option::is_none")] pub lifecycle: Option, + #[serde(default, skip_serializing_if = "Option::is_none")] + pub liveness_probe: Option, + + #[serde(default, skip_serializing_if = "Option::is_none")] + pub readiness_probe: Option, + + #[serde(default, skip_serializing_if = "Option::is_none")] + pub startup_probe: Option, + // #[serde(default, skip_serializing_if = "Option::is_none")] // features: Option, diff --git a/src/types/v1alpha1/tenant/workloads.rs b/src/types/v1alpha1/tenant/workloads.rs index 7584d5c..f9fcf41 100644 --- a/src/types/v1alpha1/tenant/workloads.rs +++ b/src/types/v1alpha1/tenant/workloads.rs @@ -18,6 +18,7 @@ use crate::types::v1alpha1::pool::Pool; use k8s_openapi::api::apps::v1; use k8s_openapi::api::core::v1 as corev1; use k8s_openapi::apimachinery::pkg::apis::meta::v1 as metav1; +use k8s_openapi::apimachinery::pkg::util::intstr::IntOrString; const VOLUME_CLAIM_TEMPLATE_PREFIX: &str = "vol"; @@ -230,6 +231,48 @@ impl Tenant { ]), volume_mounts: Some(volume_mounts), lifecycle: self.spec.lifecycle.clone(), + liveness_probe: self.spec.liveness_probe.clone().or_else(|| { + Some(corev1::Probe { + http_get: Some(corev1::HTTPGetAction { + path: Some("/rustfs/health/live".to_string()), + port: IntOrString::Int(9000), + ..Default::default() + }), + initial_delay_seconds: Some(120), + period_seconds: Some(15), + timeout_seconds: Some(5), + failure_threshold: Some(3), + ..Default::default() + }) + }), + readiness_probe: self.spec.readiness_probe.clone().or_else(|| { + Some(corev1::Probe { + http_get: Some(corev1::HTTPGetAction { + path: Some("/rustfs/health/ready".to_string()), + port: IntOrString::Int(9000), + ..Default::default() + }), + initial_delay_seconds: Some(30), + period_seconds: Some(10), + timeout_seconds: Some(5), + failure_threshold: Some(3), + ..Default::default() + }) + }), + startup_probe: self.spec.startup_probe.clone().or_else(|| { + Some(corev1::Probe { + http_get: Some(corev1::HTTPGetAction { + path: Some("/rustfs/health/startup".to_string()), + port: IntOrString::Int(9000), + ..Default::default() + }), + initial_delay_seconds: Some(10), + period_seconds: Some(5), + timeout_seconds: Some(3), + failure_threshold: Some(30), // 5min total + ..Default::default() + }) + }), // Apply pool-level resource requirements to container resources: pool.scheduling.resources.clone(), image_pull_policy: self @@ -450,6 +493,25 @@ impl Tenant { return Ok(true); } + // Check probes + if serde_json::to_value(&existing_container.liveness_probe)?
