+  `path-style` and `virtual-host` are different ways to access buckets and objects in S3, with different URL structures and domain name resolutions.
+
+  Assuming the domain name of the S3 service provider is s3.example.net, the bucket is mybucket, and the object is config.env, the specific differences are as follows:
+  - path-style: `s3.example.net/mybucket/config.env`

+  Common S3 cloud service providers often default to the `virtual-host` mode, while self-deployed services like Minio default to using `path-style`. Therefore, if you use Minio as the S3 service, you need to set `S3_ENABLE_PATH_STYLE=1`.
