Re: [boto-users] create a bucket including the current date on the name

[Nathan Hoover]

The error is pretty clear. You're trying to pass the module datetime as the parameter rather than an instance thereof. Try using str(datetime.utcnow()) on the line starting with date =. You should probably also be formatting the date to your own preference, since I'm not sure that all the characters returned by utcnow() will be valid for a bucket name. Also, do keep in mind that there is a limit of 100 buckets per account.

Any thoughts?

Thanks Nathan

Have modified to this:

#!/usr/bin/env python

# encoding: utf-8

from boto.s3.connection import S3Connection

import datetime

aws_key = 'KEY'

aws_secret_key =  'SECRET'

conn = S3Connection(aws_key, aws_secret_key)

date = str(datetime.utcnow()

bucket_name = date

bucket = conn.create_bucket(bucket_name)

____

And now I'm getting this:

AttributeError: 'module' object has no attribute 'utcnow'

Please adivse.

It might be worth it to spend some time here:

http://docs.python.org/2/library/datetime.html#module-datetime

In the meantime either:

from datetime import datetime
datetime.utcnow()

or

import datetime
datetime.datetime.utcnow()

Hello Nathan and Adrian

Even though I'm not a programmer or python-knowledged guy, your guidance was very helpful. Thanks for the reference.

To accomplish the objective is very important the following before proceeding:

Bucket names should not contain upper case letters

Bucket names should not contain underscores (_)

Bucket names should not end with a dash

Bucket names should be between 3 and 63 characters long

Bucket names cannot contain dashes next to periods (e.g., "my-.bucket.com" and "my.-bucket" are invalid)

Bucket names cannot contain periods

Below what worked for me:

#!/usr/bin/env python

# encoding: utf-8

from boto.s3.connection import S3Connection

from time import strftime

aws_key = ''

aws_secret_key =  ''

conn = S3Connection(aws_key, aws_secret_key)

bucket_creation_date_time = strftime("%m%d%y--%H%M%S")

bucket = conn.create_bucket('bucketname--' + bucket_creation_date_time)

Now, I would like to avoid using the AWS keys on the script. Will make some research.

Thanks.

Again, remember there is a limit of 100 buckets per account. Within a
bucket you can have unlimited objects:

The problem here is that you've imported the 'datetime' module instead of the
'datetime' object within the module (which is what Nathan meant). So, change:

import datetime
to
from datetime import datetime

btw, as an aside, it might be advantageous to play around with python and the
standard library itself a bit before trying out stuff with boto, else you'll
keep hitting issues like these which aren't exactly boto related.

hth,
