您可以在Pod metadata中添加Annotation来创建抢占式实例。相关Annotation如下:
|
||||
|
||||
### vk-eci 简化注解
|
||||
|
||||
Virtual Kubelet ECI 提供了简化的抢占式实例控制注解,适用于快速启用/禁用抢占式实例:
|
||||
|
||||
| Annotation | 示例值 | 是否必选 | 说明 |
|
||||
|------------|--------|----------|------|
|
||||
| `k8s.aliyun.com/eci-spot-instance` | `"true"` / `"false"` | 否 | 简化的抢占式实例开关。<br>- `"true"`:启用抢占式实例,使用 `SpotAsPriceGo` 策略(系统自动出价)<br>- `"false"` 或未设置:使用按量付费实例<br><br>**注意**:注解值不区分大小写,如 `"True"`、`"TRUE"` 均可。 |
|
||||
|
||||
#### 使用简化注解的示例
|
||||
|
||||
```yaml
|
||||
apiVersion: v1
|
||||
kind: Pod
|
||||
metadata:
|
||||
name: spot-simple-example
|
||||
annotations:
|
||||
k8s.aliyun.com/eci-spot-instance: "true" # 启用抢占式实例
|
||||
spec:
|
||||
containers:
|
||||
- name: nginx
|
||||
image: nginx:latest
|
||||
```
|
||||
|
||||
### 完整 ECI 注解
|
||||
|
||||
如果需要更细粒度的控制,可以直接使用完整的 ECI 抢占式实例注解:
|
||||
|
||||
| Annotation | 示例值 | 是否必选 | 说明 |
|
||||
|------------|--------|----------|------|
|
||||
| `k8s.aliyun.com/eci-spot-strategy` | `SpotAsPriceGo` | 是 | 抢占式实例的出价策略。可根据需要配置为:<br>- `SpotWithPriceLimit`:自定义设置抢占实例价格上限。此时必须通过`k8s.aliyun.com/eci-spot-price-limit`来指定每小时价格上限。<br>- `SpotAsPriceGo`:系统自动出价,跟随当前市场实际价格。<br><br>**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。 |
