如何获取 Amazon EC2 Spot 实例中断率

Question

我创建了一个脚本来获取按需的最佳价格，并查看相同实例的现货价格。https://github.com/fuatu/awsEC2pricefinder

这就是我在下面给出的输出。我想为每个实例添加另一列并显示“中断频率”。

(awspricing) ~/Projects/awspricing $ python awsEC2pricing.py -t 2 4

您可以在此处查看“中断频率”百分比：https ://aws.amazon.com/ec2/spot/instance-advisor/

我用谷歌搜索并检查了 boto3 ec2 方法，但找不到任何获取中断率的选项。因此，欢迎任何有关如何以编程方式获取此数据的帮助。

我从同事那里找到了解决方案。

此链接具有中断率。 https://spot-bid-advisor.s3.amazonaws.com/spot-advisor-data.json

我也相应地更新了我的代码

示例代码在这里：

def get_ec2_spot_interruption(instances=[], os=None, region=None) -> defaultdict(None):
    import requests
    import json
    results = defaultdict(None)
    url_interruptions = "https://spot-bid-advisor.s3.amazonaws.com/spot-advisor-data.json"
    try:
        response = requests.get(url=url_interruptions)
        spot_advisor = json.loads(response.text)['spot_advisor']
    except requests.exceptions.ConnectionError:
        return
    rates = {
        0: "<5%",
        1: "5-10%",
        2: "10-15%",
        3: "15-20%",
        4: ">20%"
    }
    for ii in instances:
        try:
            rate = spot_advisor[region][os][ii]['r']
            results[ii] = rates[rate]
        except KeyError:
            results[ii] = ""
    return results
