Try to create a bucket with the Python library: boto3
from boto3.session import Session session=Session(aws_access_key_id='key1', aws_secret_access_key='key2') s3 = session.resource('s3') s3.create_bucket(Bucket='kz-testbucket')
but failed to run the script with errors:
botocore.exceptions.ClientError: An error occurred (IllegalLocationConstraintException) when calling the CreateBucket operation: The unspecified location constraint is incompatible for the region specific endpoint this request was sent to.
botocore.errorfactory.BucketAlreadyExists: An error occurred (BucketAlreadyExists) when calling the CreateBucket operation: The requested bucket name is not available. The bucket namespace is shared by all users of the system. Please select a different name and try again.
It’s weird because the bucket can be created by following code:
!/usr/bin/python3 import boto3 s3 = boto3.resource('s3') s3.create_bucket(Bucket='kz-bucketname')
Searched on the Internet and found the solution – Bucket name should conform with DNS requirements (Should in FQDN format):
- Should not contain uppercase characters
- Should not contain underscores (_)
- Should be between 3 and 63 characters long
- Should not end with a dash
- Cannot contain two, adjacent periods
- Cannot contain dashes next to periods (e.g., “my-.bucket.com” and “my.-bucket” are invalid)
It works after I changed the bucket name to ‘ke.testbucket’. Related links:
