The put_bucket_replication interface sets cross-region or same-region replication rules for buckets. This article explains how to configure object replication using the put_bucket_replication interface in the Rust SDK.
Notes
- You need to fill in the region and access domain in the sample code according to your actual situation. For details, see region and access domain.
- To prevent key leakage, this example code reads the Access Key ID and Secret Access Key from environment variables. Therefore, before using the SDK, you must configure long-term access credentials. For details, see configure long-term access credentials.
- Tiered buckets do not support the put_bucket_replication call.
- Before cross-account replication, you must first grant read permissions to the source bucket and write permissions to the target bucket.
Permissions required
The Volcano Engine main account has all permissions by default, but IAM users have none by default. If you need to use a sub-account to perform the put_bucket_replication operation, the Volcano Engine main account must grant the following permissions to the sub-account through IAM policies and bucket policies:
tos:PutBucketReplication
