Description

Uploads a local file, text content or a folder hierarchy of files to Amazon S3, placing them into the specified bucket using the specified key (single object) or key prefix (multiple objects). If you are uploading large files, Write-S3Object cmdlet will use multipart upload to fulfill the request. If a multipart upload is interrupted, Write-S3Object cmdlet will attempt to abort the multipart upload. Under certain circumstances (network outage, power failure, etc.), Write-S3Object cmdlet will not be able to abort the multipart upload. In this case, in order to stop getting charged for the storage of uploaded parts, you should manually invoke the Remove-S3MultipartUploads to abort the incomplete multipart uploads.

Parameters

-BucketName <String>
The name of the bucket that will hold the uploaded content.When using this API with an access point, you must direct requests to the access point hostname. The access point hostname takes the form AccessPointName-AccountId.s3-accesspoint.Region.amazonaws.com. When using this operation using an access point through the AWS SDKs, you provide the access point ARN in place of the bucket name. For more information about access point ARNs, see Using Access Points in the Amazon Simple Storage Service Developer Guide.

Outputs

Examples

Example 1

Write-S3Object -BucketName test-files -Key "sample.txt" -File .\local-sample.txt
This command uploads the single file "local-sample.txt" to Amazon S3, creating an object with key "sample.txt" in bucket "test-files".

Example 2

Write-S3Object -BucketName test-files -File .\sample.txt
This command uploads the single file "sample.txt" to Amazon S3, creating an object with key "sample.txt" in bucket "test-files". If the -Key parameter is not supplied, the filename is used as the S3 object key.

Example 3

Write-S3Object -BucketName test-files -Key "prefix/to/sample.txt" -File .\local-sample.txt
This command uploads the single file "local-sample.txt" to Amazon S3, creating an object with key "prefix/to/sample.txt" in bucket "test-files".

Example 4

Write-S3Object -BucketName test-files -Folder .\Scripts -KeyPrefix SampleScripts\
This command uploads all files in the subdirectory "Scripts" to the bucket "test-files" and applies the common key prefix "SampleScripts" to each object. Each uploaded file will have a key of "SampleScripts/filename" where 'filename' varies.

Example 5

Write-S3Object -BucketName test-files -Folder .\Scripts -KeyPrefix SampleScripts\ -SearchPattern *.ps1
This command uploads all *.ps1 files in the local director "Scripts" to bucket "test-files" and applies the common key prefix "SampleScripts" to each object. Each uploaded file will have a key of "SampleScripts/filename.ps1" where 'filename' varies.

Example 6

Write-S3Object -BucketName test-files -Key "sample.txt" -Content "object contents"
This command creates a new S3 object containing the specified content string with key 'sample.txt'.

Example 7

Write-S3Object -BucketName test-files -File "sample.txt" -TagSet @{Key="key1";Value="value1"},@{Key="key2";Value="value2"}
This command uploads the specified file (the filename is used as the key) and applies the specified tags to the new object.

Example 8

Write-S3Object -BucketName test-files -Folder . -KeyPrefix "TaggedFiles" -Recurse -TagSet @{Key="key1";Value="value1"},@{Key="key2";Value="value2"}
