How can I change bucket name in MinIO?

Question

I have a Minio cluster that we you as on-promise object storage, We want to change bucket name in it, How do I do this?

Answer 1

IF:

• you are running a single instance minio
• you have access to the minio volume directly

Then, yes, it is simply possible by renaming the directory directly.

mv old-bucket.mydomain.example new-bucket.mydomain.example

Explanation

Let's assume minio data is stored in /data/, and we have a bucket called old-bucket.mydomain.example. Then the bucket is stored under /data/old-bucket.mydomain.example directory. Therefore, we can simply rename the directory and it would work!

Update

Please note that, there might be some issues in case of having encryption enabled on the bucket.

Answer 2

It is not possible to rename buckets: you have to create a new bucket with the desired name, copy over your data mc cp -r minio/oldbucket minio/newbucket and delete the old bucket.
