MinIO is an open-source object storage server released under the GNU AGPL v3 license. It is designed to be lightweight and highly scalable, making it suitable for cloud-native applications. MinIO is compatible with Amazon S3 cloud storage service, allowing developers to build cloud storage solutions with ease. Its primary purpose is to store unstructured data such as photos, videos, log files, backups, and container images.
When using MinIO, you might encounter an error message stating InvalidBucketName. This error typically occurs when attempting to create or access a bucket with a name that does not adhere to the required naming conventions.
Upon executing a command to create or access a bucket, the operation fails, and you receive an error message similar to:
InvalidBucketName: The specified bucket name is not valid.
The InvalidBucketName error arises when the bucket name does not comply with DNS naming conventions. MinIO, like AWS S3, requires bucket names to be DNS-compliant for compatibility and scalability reasons.
To resolve the InvalidBucketName error, ensure that your bucket names adhere to the DNS naming conventions outlined above. Follow these steps to correct the issue:
Check the bucket name you are trying to create or access. Ensure it meets the DNS naming rules. For example, if your bucket name is my_bucket, change it to my-bucket.
If the bucket name does not comply, modify it accordingly. Use a command like the following to create a new bucket with a valid name:
mc mb myminio/my-bucket
Here, mc is the MinIO Client, and myminio is the alias for your MinIO server.
After creating the bucket with a valid name, verify that the operation was successful by listing the buckets:
mc ls myminio
For more information on bucket naming rules and best practices, refer to the official MinIO documentation on Bucket Naming Guide. Additionally, explore the MinIO Client Quickstart Guide for more on using the MinIO Client.
