Create a Bucket instance. If the bucket does not exist and create is set, a new bucket is created on S3. Launching this method with create=true may affect on the bucket's ACL if the bucket already exists. Returns Bucket instance or nil if the bucket does not exist and create is not set.
s3 = RightAws::S3.new(aws_access_key_id, aws_secret_access_key) ... bucket1 = RightAws::S3::Bucket.create(s3, 'my_awesome_bucket_1') bucket1.keys #=> exception here if the bucket does not exists ... bucket2 = RightAws::S3::Bucket.create(s3, 'my_awesome_bucket_2', true) bucket2.keys #=> list of keys # create a bucket at the European location with public read access bucket3 = RightAws::S3::Bucket.create(s3,'my-awesome-bucket-3', true, 'public-read', :location => :eu) see http://docs.amazonwebservices.com/AmazonS3/2006-03-01/RESTAccessPolicy.html (section: Canned Access Policies)
# File lib/s3/right_s3.rb, line 131 def self.create(s3, name, create=false, perms=nil, headers={}) s3.bucket(name, create, perms, headers) end
Create a bucket instance. In normal use this method should not be called directly. Use RightAws::S3::Bucket.create or RightAws::S3.bucket instead.
# File lib/s3/right_s3.rb, line 139 def initialize(s3, name, creation_date=nil, owner=nil) @s3 = s3 @name = name @owner = owner @creation_date = creation_date if @creation_date && !@creation_date.is_a?(Time) @creation_date = Time.parse(@creation_date) end end
Remove all keys from a bucket. Returns true.
bucket.clear #=> true
# File lib/s3/right_s3.rb, line 330 def clear @s3.interface.clear_bucket(@name) end
Create an object copy. Returns a destination RightAws::S3::Key instance.
new_key = bucket.copy_key('logs/today/1.log','logs/today/2.log') #=> #<RightAws::S3::Key:0xb7b1e240 ... > puts key.name #=> 'logs/today/2.log' key.exists? #=> true
# File lib/s3/right_s3.rb, line 309 def copy_key(old_key_or_name, new_key_or_name) old_key_or_name = Key.create(self, old_key_or_name.to_s) unless old_key_or_name.is_a?(Key) old_key_or_name.copy(new_key_or_name) end
Delete a bucket. Bucket must be empty. If force is set, clears and deletes the bucket. Returns true.
bucket.delete(true) #=> true
# File lib/s3/right_s3.rb, line 351 def delete(force=false) force ? @s3.interface.force_delete_bucket(@name) : @s3.interface.delete_bucket(@name) end
Delete all keys where the 'folder_key' can be interpreted as a 'folder' name. Returns an array of string keys that have been deleted.
bucket.keys.map{|key| key.name}.join(', ') #=> 'test, test/2/34, test/3, test1, test1/logs' bucket.delete_folder('test') #=> ['test','test/2/34','test/3']
# File lib/s3/right_s3.rb, line 341 def delete_folder(folder, separator='/') @s3.interface.delete_folder(@name, folder, separator) end
Disables S3 server access logging on a bucket. Takes no arguments.
# File lib/s3/right_s3.rb, line 198 def disable_logging xmldoc = "<?xml version=\"1.0\" encoding=\"UTF-8\"?><BucketLoggingStatus xmlns=\"http://doc.s3.amazonaws.com/2006-03-01\"></BucketLoggingStatus>" @s3.interface.put_logging(:bucket => @name, :xmldoc => xmldoc) end
Enables S3 server access logging on a bucket. The target bucket must have been properly configured to receive server access logs.
Params: :targetbucket - either the target bucket object or the name of the target bucket :targetprefix - the prefix under which all logs should be stored bucket.enable_logging(:targetbucket=>"mylogbucket", :targetprefix=>"loggylogs/") => true
# File lib/s3/right_s3.rb, line 190 def enable_logging(params) AwsUtils.mandatory_arguments([:targetbucket, :targetprefix], params) AwsUtils.allow_only([:targetbucket, :targetprefix], params) xmldoc = "<?xml version=\"1.0\" encoding=\"UTF-8\"?><BucketLoggingStatus xmlns=\"http://doc.s3.amazonaws.com/2006-03-01\"><LoggingEnabled><TargetBucket>#{params[:targetbucket]}</TargetBucket><TargetPrefix>#{params[:targetprefix]}</TargetPrefix></LoggingEnabled></BucketLoggingStatus>" @s3.interface.put_logging(:bucket => @name, :xmldoc => xmldoc) end
Return a list of grantees.
# File lib/s3/right_s3.rb, line 357 def grantees Grantee::grantees(self) end
Retrieve key information from Amazon. The key_name is a String or Key instance. Retrieves meta-header information if head is true. Returns new Key instance.
key = bucket.key('logs/today/1.log', true) #=> #<RightAws::S3::Key:0xb7b1e240 ... > # is the same as: key = RightAws::S3::Key.create(bucket, 'logs/today/1.log') key.head

Retrieve a group of keys from Amazon. options is a hash: { 'prefix'=>", 'marker'=>", 'max-keys'=>5, 'delimiter'=>" }). Retrieves meta-headers information if head it true. Returns an array of Key instances.
bucket.keys #=> # returns all keys from bucket bucket.keys('prefix' => 'logs') #=> # returns all keys that starts with 'logs'
# File lib/s3/right_s3.rb, line 211 def keys(options={}, head=false) keys_and_service(options, head)[0] end
Same as keys method but return an array of [keys, service_data]. where service_data is a hash with additional output information.
keys, service = bucket.keys_and_service({'max-keys'=> 2, 'prefix' => 'logs'}) p keys #=> # 2 keys array p service #=> {"max-keys"=>"2", "prefix"=>"logs", "name"=>"my_awesome_bucket", "marker"=>"", "is_truncated"=>true}

Returns the bucket location
# File lib/s3/right_s3.rb, line 169 def location @location ||= @s3.interface.bucket_location(@name) end
Retrieves the logging configuration for a bucket. Returns a hash of {:enabled, :targetbucket, :targetprefix}
bucket.logging_info() => {:enabled=>true, :targetbucket=>"mylogbucket", :targetprefix=>"loggylogs/"}

Return a public link to bucket.
bucket.public_link #=> 'https://s3.amazonaws.com:443/my_awesome_bucket'

Store object data. The key is a String or Key instance. Returns true.
bucket.put('logs/today/1.log', 'Olala!') #=> true
# File lib/s3/right_s3.rb, line 274 def put(key, data=nil, meta_headers={}, perms=nil, headers={}) key = Key.create(self, key.to_s, data, meta_headers) unless key.is_a?(Key) key.put(data, perms, headers) end
