如何获取亚马逊EC2竞价实例的中断率

Question

我已创建了一个脚本，用于获取按需实例的最佳价格，并查看相同实例的竞价价格。 https://github.com/fuatu/awsEC2pricefinder 以下是我的输出结果。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/ 我通过谷歌搜索和检查boto3 ec2方法，未找到任何选项来获取中断率。因此，欢迎提供帮助以展示如何以编程方式获取这些数据。

你好，如何查找所有的EC2实例而不仅仅是EBS Only的一个。<code>{'Type': 'TERM_MATCH', 'Field': 'storage', 'Value': '仅限EBS'},</code> - Manu Batham

我从同事那里找到了解决方案。

这个链接包含了中断率。 https://spot-bid-advisor.s3.amazonaws.com/spot-advisor-data.json 我也相应地更新了我的代码。

样本代码在此处：

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
