以下命令将生命周期配置应用于名为
my-bucket
的存储桶:aws s3api put-bucket-lifecycle-configuration --bucket
my-bucket
--lifecycle-configurationfile://lifecycle.json
文件
lifecycle.json
是当前文件夹中指定两个规则的 JSON 文档:{ "Rules": [ { "ID": "Move rotated logs to Glacier", "Prefix": "rotated/", "Status": "Enabled", "Transitions": [ { "Date": "2015-11-10T00:00:00.000Z", "StorageClass": "GLACIER" } ] }, { "Status": "Enabled", "Prefix": "", "NoncurrentVersionTransitions": [ { "NoncurrentDays": 2, "StorageClass": "GLACIER" } ], "ID": "Move old versions to Glacier" } ] }
第一条规则在指定日期将带有前缀
rotated
的文件移动到 Glacier。第二条规则在旧对象版本不再是最新版本时将其移至 Glacier。有关可接受时间戳格式的信息,请参阅《AWS CLI 用户指南》中的“指定参数值”。-
