Amazon S3 boto: How do you rename a file in a bucket?

How do you rename a S3 key in a bucket with boto?

amazon S3 boto - how to create folder?

how can i create a folder under a bucket using boto library for amazon s3, i followed the manual, and create keys with contents with permission, metadata etc, but no where in the boto's documentation say how to create folders under bucket, or create folder under folders in bucket.

Django Storage Backend for S3

I'm looking for a good Django custom storage backend for use with Amazon S3.

I've been googling around and found a lot of blog posts with code snippets or half-baked gist.github.com one-off jobs. But I can't seem to find a solid, well-tested one.

Is there a widely accepted standard Amazon S3 Django custom storage backend out there? It doesn't particularly matter to me what Python backend library it uses--i.e., either S3.py or boto are fine.

boto.exception.S3ResponseError: S3ResponseError: 403 Forbidden

I'm trying to get django to upload static files to S3, but istead I'm getting a 403 forbidden error, and I'm not sure why.

How do I install boto?

So that I am able to work with it within my python scripts?

How to launch EC2 instance with Boto, specifying size of EBS?

I'm using boto/python to launch a new EC2 instance that boots from an EBS volume. At the time I launch the instance, I'd like to override the default size of the booting EBS volume.

I found no boto methods or parameters that might fit into my launch code:

ec2 = boto.connect_ec2( ACCESS_KEY, SECRET_KEY, region=region )

reservation = ec2.run_instances( image_id=AMI_ID, 
                                 key_name=EC2_KEY_HANDLE, 
                                 instance_type=INSTANCE_TYPE,
                                 security_groups = [ SECGROUP_HANDLE, ] )

The web page below shows how to increase the size of a running EC2-instance's EBS volume using command-line tools, but I'd like to use boto at the time the EC2 instance is specified:

http://alestic.com/2010/02/ec2-resize-running-ebs-root

Thank you.

With boto, how can I name a newly spawned EC2 instance?

I'm using boto to spawn a new EC2 instance based on an AMI.

The ami.run method has a number of parameters, but none for "name" - maybe it's called something different?

Fastest way to download 3 million objects from a S3 bucket

I've tried using Python + boto + multiprocessing, S3cmd and J3tset but struggling with all of them.

Any suggestions, perhaps a ready-made script you've been using or another way I don't know of?

EDIT:

eventlet+boto is a worthwhile solution as mentioned below. Found a good eventlet reference article here http://web.archive.org/web/20110520140439/http://teddziuba.com/2010/02/eventlet-asynchronous-io-for-g.html

I've added the python script that I'm using right now below.

Why are no Amazon S3 authentication handlers ready?

I have my $AWS_ACCESS_KEY_ID and $AWS_SECRET_ACCESS_KEY environment variables set properly, and I run this code:

import boto
conn = boto.connect_s3()

and get this error:

boto.exception.NoAuthHandlerFound: No handler was ready to authenticate. 1 handlers were checked. ['HmacAuthV1Handler']

What's happening? I don't know where to start debugging.

It seems boto isn't taking the values from my environment variables. If I pass in the key id and secret key as arguments to the connection constructor, this works fine.

Disable boto logging without modifying the boto files

I am using the Boto library to talk to AWS. I want to disable logging. (Or redirect to /dev/null or other file). I cant find an obvious way to do this. I tried this, but that doesn't seem to help.

import boto
boto.set_file_logger('boto', 'logs/boto.log')

This says it is possible, http://developer.amazonwebservices.com/connect/thread.jspa?messageID=52727&#52727 but AFAIK the documentation doesnt tell how.

Signature/Expires/Access Key ID appearing in URL Params. Django/Boto/S3

Thumbnail URLS have params in them. I'm not sure why. I think they related to sorl-thumbnail or boto storage we're using. How do I remove the additional params from the URL? Are they coming from boto/s3 or sorl. I've no idea how to debug.

Boto EC2: Create an instance with tags

Is there a way with the boto python API to specify tags when creating an instance? I'm trying to avoid having to create an instance, fetch it and then add tags. It would be much easier to have the instance either pre-configured to have certain tags or to specify tags when I execute the following command:

ec2server.create_instance(
        ec2_conn, ami_name, security_group, instance_type_name, key_pair_name, user_data
    )

How to change metadata on an object in Amazon S3

If you have already uploaded an object to an Amazon S3 bucket, how do you change the metadata using the API? It is possible to do this in the AWS Management Console, but it is not clear how it could be done programmatically. Specifically, I'm using the boto API in Python and from reading the source it is clear that using key.set_metadata only works before the object is created as it just effects a local dictionary.

How to auto assign public ip to EC2 instance with boto

I have to start a new machine with ec2.run_instances in a given subnet but also to have a public ip auto assigned (not fixed elastic ip).

When one starts a new machine from the Amazon's web EC2 Manager via the Request Instance (Instance details) there is a check-box called Assign Public IP to Auto-assign Public IP. See it highlighted in the screenshot:

How can I achieve that check-box functionality with boto?

How do I test a module that depends on boto and an Amazon AWS service?

I'm writing a very small Python ORM around boto.dynamodb.layer2. I would like to write tests for it, but I don't want the tests to actually communicate with AWS, as this would require complicated setup, credentials, network access, etc.

Since I plan to open source the module, including credentials in the source seems like a bad idea since I will get charged for usage, and including credentials in the environment is a pain.

Coupling my tests to the network seems like a bad idea, as it makes the tests run slower, or may cause tests to fail due to network errors or throttling. My goal is not to test boto's DynamoDB interface, or AWS. I just want to test my own code.

I plan to use unittest2 to write the tests and mock to mock out the parts of boto that hit the network, but I've never done this before, so my question boils down to these:

1. Am I going about this the right way?
2. Has anyone else done this?
3. Are there any particular points in the boto.dynamodb interface that would be best to mock out?
