- `SpotAsPriceGo`:系统自动出价,跟随当前市场实际价格。

**重要**:使用`SpotAsPriceGo`策略时,如果对应可用区规格资源紧张,最高价格可能会达到按量价格。 | diff --git a/eci.go b/eci.go index 07940ff..38289f1 100644 --- a/eci.go +++ b/eci.go @@ -35,6 +35,11 @@ const serviceAccountSecretMountPath = "/var/run/secrets/kubernetes.io/serviceacc const podTagTimeFormat = "2006-01-02T15-04-05Z" const timeFormat = "2006-01-02T15:04:05Z" +// Pod annotation constants +const ( + AnnotationECISpotInstance = "k8s.aliyun.com/eci-spot-instance" +) + // ECIProvider implements the virtual-kubelet provider interface and communicates with Alibaba Cloud's ECI APIs. type ECIProvider struct { eciClient *eci.Client @@ -208,9 +213,14 @@ func (p *ECIProvider) CreatePod(ctx context.Context, pod *v1.Pod) error { request.AutoCreateEip = requests.Boolean(strconv.FormatBool(true)) } - // 添加抢占式实例策略配置 - request.SpotStrategy = "SpotAsPriceGo" // 设置抢占式实例策略为按价格竞价 - //request.SpotDuration = 0 // 设置抢占式实例持续时间为0(非定时抢占) + // 抢占式实例配置 - 支持通过注解控制是否启用 + if spotInstance, exists := pod.Annotations[AnnotationECISpotInstance]; exists { + if strings.ToLower(spotInstance) == "true" { + request.SpotStrategy = "SpotAsPriceGo" // 启用抢占式实例,使用按价格竞价策略 + } + // false 时不设置 SpotStrategy,使用按量实例 + } + // 默认行为:不设置 SpotStrategy,使用按量实例 // get containers containers, err := p.getContainers(pod, false) @@ -321,7 +331,7 @@ func (p *ECIProvider) GetContainerLogs(ctx context.Context, namespace, podName, request := eci.CreateDescribeContainerLogRequest() request.ContainerGroupId = eciId request.ContainerName = containerName - request.Tail = requests.Integer(opts.Tail) + request.Tail = requests.Integer(strconv.Itoa(opts.Tail)) // get logs from cg logContent := "" diff --git a/eci_test.go b/eci_test.go new file mode 100644 index 0000000..f41d402 --- /dev/null +++ b/eci_test.go @@ -0,0 +1,93 @@ +package alibabacloud + +import ( + "strings" + "testing" + + v1 "k8s.io/api/core/v1" + metav1 "k8s.io/apimachinery/pkg/apis/meta/v1" +) + +func TestAnnotationECISpotInstance(t *testing.T) { + // Test that the annotation constant is correctly defined + if AnnotationECISpotInstance != "k8s.aliyun.com/eci-spot-instance" { + t.Errorf("AnnotationECISpotInstance = %s, want %s", AnnotationECISpotInstance, "k8s.aliyun.com/eci-spot-instance") + } +} + +func TestSpotStrategyAnnotation(t *testing.T) { + tests := []struct { + name string + annotationValue string + expectSpotSet bool + }{ + { + name: "annotation true sets SpotStrategy", + annotationValue: "true", + expectSpotSet: true, + }, + { + name: "annotation false does not set SpotStrategy", + annotationValue: "false", + expectSpotSet: false, + }, + { + name: "no annotation does not set SpotStrategy", + annotationValue: "", + expectSpotSet: false, + }, + { + name: "invalid annotation value does not set SpotStrategy", + annotationValue: "invalid", + expectSpotSet: false, + }, + { + name: "case insensitive TRUE sets SpotStrategy", + annotationValue: "TRUE", + expectSpotSet: true, + }, + { + name: "case insensitive True sets SpotStrategy", + annotationValue: "True", + expectSpotSet: true, + }, + { + name: "case insensitive FaLsE does not set SpotStrategy", + annotationValue: "FaLsE", + expectSpotSet: false, + }, + } + + for _, tt := range tests { + t.Run(tt.name, func(t *testing.T) { + pod := &v1.Pod{ + ObjectMeta: metav1.ObjectMeta{ + Annotations: make(map[string]string), + }, + } + + if tt.annotationValue != "" { + pod.Annotations[AnnotationECISpotInstance] = tt.annotationValue + } + + // Verify annotation is correctly set on pod + if tt.annotationValue != "" { + val, exists := pod.Annotations[AnnotationECISpotInstance] + if !exists { + t.Errorf("Annotation %s should exist", AnnotationECISpotInstance) + } + if val != tt.annotationValue { + t.Errorf("Expected annotation value %s, got %s", tt.annotationValue, val) + } + } + + // Verify case-insensitive comparison logic + if tt.annotationValue != "" { + result := strings.ToLower(tt.annotationValue) == "true" + if result != tt.expectSpotSet { + t.Errorf("strings.ToLower(%q) == \"true\" = %v, want %v", tt.annotationValue, result, tt.expectSpotSet) + } + } + }) + } +}
