如何通过标签查找minio对象？

Question

我正在使用minio

mc

客户端。可以使用

mc find

命令来查找 minio 文件或对象。但我找不到如何按标签查找或过滤文件。有什么想法吗？

Answer 1

S3 的 ListObject API 不返回对象标签，因此您不能使用

mc find

来查询标签。相反，您必须使用

GetObjectTagging

S3 API 来获取对象的标签。

GET /{Key+}?tagging&versionId=VersionId HTTP/1.1
Host: Bucket.s3.amazonaws.com
x-amz-expected-bucket-owner: ExpectedBucketOwner
x-amz-request-payer: RequestPaye

Answer 2

在 MinIO 客户端中您可以使用以下命令： mc find --tags="tag=value" AliasMinIOName/BucketName/

例如： 我的 MinIO 别名是 myminio 我的存储桶名称是示例 我的标签键，标签值是key1=value1

最后： mc find --tags="key1=value1" myminio/sample/

列出示例存储桶中具有 key1=value1 标签的所有对象。

Answer 3

--标签

可选 mc 版本新增：RELEASE.2023-04-12T02-21-51Z

仅适用于 MinIO 部署。

返回带有与指定 RE2 RegEx 模式匹配的标签的对象。使用格式 --tag="KEY=regexValue"。

您可以传递带有空值的键。在这种情况下， mc 查找匹配项 没有元数据键或元数据键值为空的对象。

您可以多次使用该标志来匹配附加标签的对象。要返回，对象必须具有所有标签的匹配值。
