由于亚马逊从ec2-ami-tools切换到awscli（检查this），Robert Sindall的solution已不再可接受。
所以我决定为新的python / json标准重写他的脚本。
随时提出任何问题或提供解决方案。
答案 0 :(得分：0)
请正确安装和配置awscli。对于MacOS，我建议使用brew版本。
安装后请勿忘记运行$payment = Auth::user()->payments()->orderBy('updated_at', 'desc')->first();
对我来说完美无瑕，但无论如何都要自行承担使用风险。
aws configure然后只需运行它：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)
