无法使用AWS Python Boto3创建S3存储桶（在特定区域）

Question

I am trying to create bucket using aws python boto 3.

Here is my code:-

import boto3
response = S3_CLIENT.create_bucket(
  Bucket='symbols3arg',
  CreateBucketConfiguration={'LocationConstraint': 'eu-west-1'}
)
print(response)

I am getting below error:-

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.

Answer 1

This happens you configured a different region during aws configure in specifying a different region in s3 client object initiation.

Suppose my AWS config look like

$ aws configure
AWS Access Key ID [None]: AKIAIOSFODEXAMPLE
AWS Secret Access Key [None]: wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY
Default region name [None]: us-west-2
Default output format [None]: json

and my python script for creating bucket

import logging
import boto3
from botocore.exceptions import ClientError


def create_bucket(bucket_name, region=None):
    # Create bucket
    try:
        if region is None:
            s3_client = boto3.client('s3')
            s3_client.create_bucket(Bucket=bucket_name)
        else:
            s3_client = boto3.client('s3')
            location = {'LocationConstraint': region}
            s3_client.create_bucket(Bucket=bucket_name,
                                    CreateBucketConfiguration=location)
    except ClientError as e:
        logging.error(e)
        return False
    return True

create_bucket("test-bucket-in-region","us-west-1")

This will throw the below error

 ERROR:root:An error occurred (IllegalLocationConstraintException) when calling the CreateBucket operation: The us-west-1 location constraint is incompatible for the region specific endpoint this request was sent to.

To solve this issue all you need to specify the region in s3 client object initiation. A working example in different region regardless of aws configure

import logging
import boto3
from botocore.exceptions import ClientError


def create_bucket(bucket_name, region=None):
    """Create an S3 bucket in a specified region

    If a region is not specified, the bucket is created in the S3 default
    region (us-east-1).

    :param bucket_name: Bucket to create
    :param region: String region to create bucket in, e.g., 'us-west-2'
    :return: True if bucket created, else False
    """

    # Create bucket
    try:
        if region is None:
            s3_client = boto3.client('s3')
            s3_client.create_bucket(Bucket=bucket_name)
        else:
            s3_client = boto3.client('s3', region_name=region)
            location = {'LocationConstraint': region}
            s3_client.create_bucket(Bucket=bucket_name,
                                    CreateBucketConfiguration=location)
    except ClientError as e:
        logging.error(e)
        return False
    return True

create_bucket("my-working-bucket","us-west-1")

create-an-amazon-s3-bucket

Answer 2

Send the command to S3 in the same region:

import boto3

s3_client = boto3.client('s3', region_name='eu-west-1')
response = s3_client.create_bucket(
  Bucket='symbols3arg',
  CreateBucketConfiguration={'LocationConstraint': 'eu-west-1'}
)

Answer 3

You can try the following code.

import boto3

client = boto3.client('s3',region_name="aws_region_code")

response = client.create_bucket(
    Bucket='string'
)

Hope, it might helps.
