Adds an object to a bucket. You must have WRITE permissions on a bucket to add an object to it.
Amazon S3 never adds partial objects; if you receive a success response, Amazon S3 added the entire object to the bucket.
Amazon S3 is a distributed system. If it receives multiple write requests for the same object simultaneously, it overwrites all but the last object written. Amazon S3 does not provide object locking; if you need this, make sure to build it into your application layer or use versioning instead.
To ensure that data is not corrupted traversing the network, use the Content-MD5
header. When you use this header, Amazon S3 checks the object against the provided MD5 value and, if they do not match, returns an error. Additionally, you can calculate the MD5 while putting an object to Amazon S3 and compare the returned ETag to the calculated MD5 value.
Note
To successfully complete the
PutObject
request, you must have thes3:PutObject
in your IAM permissions.To successfully change the objects acl of your
PutObject
request, you must have thes3:PutObjectAcl
in your IAM permissions.The
Content-MD5
header is required for any request to upload an object with a retention period configured using Amazon S3 Object Lock. For more information about Amazon S3 Object Lock, see Amazon S3 Object Lock Overview in the Amazon S3 User Guide .
Server-side Encryption
You can optionally request server-side encryption. With server-side encryption, Amazon S3 encrypts your data as it writes it to disks in its data centers and decrypts the data when you access it. You have the option to provide your own encryption key or use Amazon Web Services managed encryption keys (SSE-S3 or SSE-KMS). For more information, see Using Server-Side Encryption .
If you request server-side encryption using Amazon Web Services Key Management Service (SSE-KMS), you can enable an S3 Bucket Key at the object-level. For more information, see Amazon S3 Bucket Keys in the Amazon S3 User Guide .
Access Control List (ACL)-Specific Request Headers
You can use headers to grant ACL- based permissions. By default, all objects are private. Only the owner has full access control. When adding a new object, you can grant permissions to individual Amazon Web Services accounts or to predefined groups defined by Amazon S3. These permissions are then added to the ACL on the object. For more information, see Access Control List (ACL) Overview and Managing ACLs Using the REST API .
If the bucket that you’re uploading objects to uses the bucket owner enforced setting for S3 Object Ownership, ACLs are disabled and no longer affect permissions. Buckets that use this setting only accept PUT requests that don’t specify an ACL or PUT requests that specify bucket owner full control ACLs, such as the bucket-owner-full-control
canned ACL or an equivalent form of this ACL expressed in the XML format. PUT requests that contain other ACLs (for example, custom grants to certain Amazon Web Services accounts) fail and return a 400
error with the error code AccessControlListNotSupported
.
For more information, see Controlling ownership of objects and disabling ACLs in the Amazon S3 User Guide .
Note
If your bucket uses the bucket owner enforced setting for Object Ownership, all objects written to the bucket by any account will be owned by the bucket owner.
Storage Class Options
By default, Amazon S3 uses the STANDARD Storage Class to store newly created objects. The STANDARD storage class provides high durability and high availability. Depending on performance needs, you can specify a different Storage Class. Amazon S3 on Outposts only uses the OUTPOSTS Storage Class. For more information, see Storage Classes in the Amazon S3 User Guide .
Versioning
If you enable versioning for a bucket, Amazon S3 automatically generates a unique version ID for the object being stored. Amazon S3 returns this ID in the response. When you enable versioning for a bucket, if Amazon S3 receives multiple write requests for the same object simultaneously, it stores all of the objects.
For more information about versioning, see Adding Objects to Versioning Enabled Buckets . For information about returning the versioning state of a bucket, see GetBucketVersioning .

Specifies the algorithm to use to when encrypting the object (for example, AES256).
--sse-customer-key
(string)
Specifies the customer-provided encryption key for Amazon S3 to use in encrypting data. This value is used to store the object and then it is discarded; Amazon S3 does not store the encryption key. The key must be appropriate for use with the algorithm specified in the
x-amz-server-side-encryption-customer-algorithm
header.
--sse-customer-key-md5
(string)
Specifies the 128-bit MD5 digest of the encryption key according to RFC 1321. Amazon S3 uses this header for a message integrity check to ensure that the encryption key was transmitted without error.

If
x-amz-server-side-encryption
is present and has the value ofaws:kms
, this header specifies the ID of the Amazon Web Services Key Management Service (Amazon Web Services KMS) symmetrical customer managed key that was used for the object. If you specifyx-amz-server-side-encryption:aws:kms
, but do not provide``x-amz-server-side-encryption-aws-kms-key-id`` , Amazon S3 uses the Amazon Web Services managed key to protect the data. If the KMS key does not exist in the same account issuing the command, you must use the full ARN and not just the ID.
--ssekms-encryption-context
(string)
Specifies the Amazon Web Services KMS Encryption Context to use for object encryption. The value of this header is a base64-encoded UTF-8 string holding JSON with the encryption context key-value pairs.
--bucket-key-enabled
| --no-bucket-key-enabled
(boolean)
Specifies whether Amazon S3 should use an S3 Bucket Key for object encryption with server-side encryption using AWS KMS (SSE-KMS). Setting this header to
true
causes Amazon S3 to use an S3 Bucket Key for object encryption with SSE-KMS.Specifying this header with a PUT action doesn’t affect bucket-level settings for S3 Bucket Key.
--request-payer
(string)
Confirms that the requester knows that they will be charged for the request. Bucket owners need not specify this parameter in their requests. For information about downloading objects from Requester Pays buckets, see Downloading Objects in Requester Pays Buckets in the Amazon S3 User Guide .

Specifies whether a legal hold will be applied to this object. For more information about S3 Object Lock, see Object Lock .
Possible values:
ON
OFF
--expected-bucket-owner
(string)

403 Forbidden
(access denied).
--cli-input-json
| --cli-input-yaml
(string)
Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton
. If other arguments are provided on the command line, those values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally. This may not be specified along with --cli-input-yaml
.
--generate-cli-skeleton
(string)
Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input
, prints a sample input JSON that can be used as an argument for --cli-input-json
. Similarly, if provided yaml-input
it will print a sample input YAML that can be used with --cli-input-yaml
. If provided with the value output
, it validates the command inputs and returns a sample output JSON for that command.
See ‘aws help’ for descriptions of global parameters.
The following example uses the put-object
command to upload an object to Amazon S3:
aws s3api put-object --bucket text-content --key dir-1/my_images.tar.bz2 --body my_images.tar.bz2
The following example shows an upload of a video file (The video file is specified using Windows file system syntax.):
aws s3api put-object --bucket text-content --key dir-1/big-video-file.mp4 --body e:\media\videos\f-sharp-3-data-services.mp4
