删除未使用的亚马逊EC2快照

Question

由于亚马逊从EC2-ami工具转向awscli (检查这)，Robert的解决方案不再被接受。

因此，我决定为新的python/json标准重写他的脚本。

请随意提出任何问题或提供解决方案。

Answer 1

请正确安装和配置阿夫斯克利。对于MacOS，我推荐酿制版本。

安装后不要忘记运行aws configure

对我来说是完美无缺的，但无论如何，你要冒着自己的风险使用它。

import json, subprocess

def remove_unused_snaps(region):
    line = 'aws ec2 describe-images --region {} --owners self'.format(region)
    p = subprocess.Popen(line.split(),
                         stdout=subprocess.PIPE, stderr=subprocess.PIPE)
    out, err = p.communicate()
    obj = json.loads(out.decode("utf-8"))

    snaps_used = set(i['BlockDeviceMappings'][0]['Ebs']['SnapshotId'] for i in obj['Images'])

    line = 'aws ec2 describe-snapshots --region {} --owner-ids self'.format(region)
    p = subprocess.Popen(line.split(),
                         stdout=subprocess.PIPE, stderr=subprocess.PIPE)
    out, err = p.communicate()
    obj = json.loads(out.decode("utf-8"))

    snaps_old = set(i['SnapshotId'] for i in obj['Snapshots'])

    line = 'aws ec2 delete-snapshot --region {} --snapshot-id'.format(region)
    for snap in list(snaps_old - snaps_used):
        p = subprocess.Popen(line.split() + [snap],
                             stdout=subprocess.PIPE, stderr=subprocess.PIPE)
        out, err = p.communicate()
        print(snap, out, err)

然后运行它：remove_unused_snaps('us-west-2')
