Creating a Bucket

I’m getting error’s about regarding boto3 not being able to locate credentials even though I’ve configured the profile, credentials and config with the correct info. Also, I’ve had to modify the script b/c of the us-east api issue in order to get it to create a bucket. The script provided in the video results in an error even with the if/else logic provided

Hi bdorsey, are you located in the us-east region?

yes I am

Hi I am getting error Invalid type for parameter CreateBucketConfiguration.LocationConstr aint, value: None, type: <class ‘NoneType’>, valid types: <class ‘s tr’>

Hi pksccbt, it looks like boto3 is not able to read your region. Did you set up a config file at the end of the Installation and Setup video?

Should be located at ~/.aws/config and contain:

[default]
region = YOUR_PREFERRED_REGION

Yes I had set my region. It is region = us-east-2

Hi it is still not working.

Interesting, I’m not sure why it wouldn’t collect that info correctly.

Can you post the entire error traceback? I’d like to see if it’s your S3 connection or the bucket creation line that is causing the problem. Somewhere your ‘us-east-2’ region is not being passed to boto3 the right way.

Thanks!

I’m getting an error when I try to run s3_resource= boto3.resource(‘s3’) with AttributeError: module boto3 has no attribute ‘resource’ I’m running python3 and boto3 is up to date. This is when i try the part in the interactive shell to create the bucket.

I get the following error message in my python session.

>>> first_bucket_name, first_response = create_bucket(
... 
... bucket_prefix='firstpythonbucket',
... s3_connection=s3_resource.meta.client)
Traceback (most recent call last):
  File "<stdin>", line 4, in <module>
NameError: name 's3_resource' is not defined

Has anyone else got this same issue?

Was getting errors as well. The following worked for me after looking at video & tutorial.`#s3 bucket using a client

import boto3 from boto3_guide import create_bucket s3_resource = boto3.resource(‘s3’) first_bucket_name, first_response = create_bucket( … bucket_prefix=’firstpythonbucket’, … s3_connection=s3_resource.meta.client) firstpythonbucket5db905a0-b49d-4fa5-9d43-4f990c403de5 us-east-1

second_bucket_name, second_response = create_bucket( … bucket_prefix=’secondpythonbucket’, s3_connection=s3_resource) secondpythonbucketf2039215-b1d1-4f2c-99ea-7ed5d4696858 us-east-1`

Hi, I am getting an error on the first step where you print out bucket name with the create_bucket_name function. I am using VSCode and it looks like its having an issue finding boto3 although I already pip installed it.

import boto3
import uuid     #universal unique identifier for unique bucket name

def create_bucket_name(bucket_prefix):
    #bucket name must be between 3-63 chars long
    return ''.join([bucket_prefix, str(uuid.uuid4())])

# test bucket name creation
print(create_bucket_name('test_name'))

Error:

Disregard my previous comment, I fixed the issue. It was with VSCode python interpreter.

Hi Joe,

Can you please explain the use of session in more detail?

I found the below code snippted that also created S3 bucket without using “Sessions”

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

JSON output from S3 boto client.

Hi, I’m getting JSON-like output as the result of printing the list of buckets using the boto3 client. Is there any way to catch this part of output that prints a list of buckets? In reality, such JSON output is more obscure than the result of the aws s3 ls command.
