By default, containers use the same logging driver that the Docker daemon uses. However the container can use a different logging driver than the Docker daemon by specifying a log driver with this parameter in the container definition. To use a different logging driver for a container, the log system must be configured properly on the container instance (or on a different log server for remote logging options). Amazon ECS currently supports a subset of the logging drivers available to the Docker daemon (shown in the [LogConfiguration](https://docs.aws.amazon.com/AmazonECS/latest/APIReference/API_LogConfiguration.html) data type). Additional log drivers may be available in future releases of the Amazon ECS container agent. This parameter requires version 1.18 of the Docker Remote API or greater on your container instance. To check the Docker Remote API version on your container instance, log in to your container instance and run the following command: sudo docker version --format '{{.Server.APIVersion}}' The Amazon ECS container agent running on a container instance must register the logging drivers available on that instance with the ECS_AVAILABLE_LOGGING_DRIVERS environment variable before containers placed on that instance can use these log configuration options. For more information, see [Amazon ECS Container Agent Configuration](https://docs.aws.amazon.com/AmazonECS/latest/developerguide/ecs-agent-config.html) in the Amazon Elastic Container Service Developer Guide.

For more information about Zonal endpoint API operations that include the Availability Zone in the request endpoint, see [S3 Express One Zone APIs](https://docs.aws.amazon.com/AmazonS3/latest/userguide/s3-express-APIs.html) in the Amazon S3 User Guide. To make Zonal endpoint API requests on a directory bucket, use the CreateSession API operation. Specifically, you grant s3express:CreateSession permission to a bucket in a bucket policy or an IAM identity-based policy. Then, you use IAM credentials to make the CreateSession API request on the bucket, which returns temporary security credentials that include the access key ID, secret access key, session token, and expiration. These credentials have associated permissions to access the Zonal endpoint API operations. After the session is created, you don’t need to use other policies to grant permissions to each Zonal endpoint API individually. Instead, in your Zonal endpoint API requests, you sign your requests by applying the temporary security credentials of the session to the request headers and following the SigV4 protocol for authentication. You also apply the session token to the x-amz-s3session-token request header for authorization. Temporary security credentials are scoped to the bucket and expire after 5 minutes. After the expiration time, any calls that you make with those credentials will fail. You must use IAM credentials again to make a CreateSession API request that generates a new set of temporary credentials for use. Temporary credentials cannot be extended or refreshed beyond the original specified interval. If you use Amazon Web Services SDKs, SDKs handle the session token refreshes automatically to avoid service interruptions when a session expires. We recommend that you use the Amazon Web Services SDKs to initiate and manage requests to the CreateSession API.

By default, the operation uses verbose mode in which the response includes the result of deletion of each key in your request. In quiet mode the response includes only keys where the delete operation encountered an error. For a successful deletion in a quiet mode, the operation does not return any information about the delete in the response body. When performing this action on an MFA Delete enabled bucket, that attempts to delete any versioned objects, you must include an MFA token. If you do not provide one, the entire request will fail, even if there are non-versioned objects you are trying to delete. If you provide an invalid token, whether there are versioned keys in the request or not, the entire Multi-Object Delete request will fail.

Permissions If you are using an identity other than the root user of the Amazon Web Services account that owns the bucket, the calling identity must both have the GetBucketPolicy permissions on the specified bucket and belong to the bucket owner's account in order to use this operation. If you don't have GetBucketPolicy permissions, Amazon S3 returns a 403 Access Denied error. If you have the correct permissions, but you're not using an identity that belongs to the bucket owner's account, Amazon S3 returns a 405 Method Not Allowed error. To ensure that bucket owners don't inadvertently lock themselves out of their own buckets, the root principal in a bucket owner's Amazon Web Services account can perform the GetBucketPolicy, PutBucketPolicy, and DeleteBucketPolicy API actions, even if their bucket policy explicitly denies the root principal's access. Bucket owner root principals can only be blocked from performing these API actions by VPC endpoint policies and Amazon Web Services Organizations policies.

We recommend that you wait for 15 minutes after enabling versioning before issuing write operations (PUT or DELETE) on objects in the bucket. Sets the versioning state of an existing bucket. You can set the versioning state with one of the following values: Enabled—Enables versioning for the objects in the bucket. All objects added to the bucket receive a unique version ID. Suspended—Disables versioning for the objects in the bucket. All objects added to the bucket receive the version ID null. If the versioning state has never been set on a bucket, it has no versioning state; a [GetBucketVersioning](https://docs.aws.amazon.com/AmazonS3/latest/API/API_GetBucketVersioning.html) request does not return a versioning state value. In order to enable MFA Delete, you must be the bucket owner. If you are the bucket owner and want to enable MFA Delete in the bucket versioning configuration, you must include the x-amz-mfa request header and the Status and the MfaDelete request elements in a request to set the versioning state of the bucket. If you have an object expiration lifecycle configuration in your non-versioned bucket and you want to maintain the same permanent delete behavior when you enable versioning, you must add a noncurrent expiration policy. The noncurrent expiration lifecycle configuration will manage the deletes of the noncurrent object versions in the version-enabled bucket. (A version-enabled bucket maintains one current and zero or more noncurrent object versions.)

Permissions
     ///
     /// * General purpose bucket permissions - To perform a multipart upload with encryption using an Key Management Service key, the requester must have permission to the kms:Decrypt and kms:GenerateDataKey actions on the key. The requester must also have permissions for the kms:GenerateDataKey action for the CreateMultipartUpload API. Then, the requester needs permissions for the kms:Decrypt action on the UploadPart and UploadPartCopy APIs. These permissions are required because Amazon S3 must decrypt and read data from the encrypted file parts before it completes the multipart upload.

The CompleteMultipartUpload API operation\n         concatenates the parts that you provide in the list.

While processing is in progress, Amazon S3\n         periodically sends white space characters to keep the connection from timing out. A request\n         could fail after the initial <code>200 OK</code> response has been sent. This means that a\n            <code>200 OK</code> response can contain either a success or an error.

Upon receiving\n         this request, Amazon S3 concatenates all the parts in ascending order by part number to create a\n         new object. In the CompleteMultipartUpload request, you must provide the parts list and\n         ensure that the parts list is complete. The CompleteMultipartUpload API operation\n         concatenates the parts that you provide in the list. For each part in the list, you must\n         provide the <code>PartNumber</code> value and the <code>ETag</code> value that are returned\n         after that part was uploaded.</p>\n         <p>The processing of a CompleteMultipartUpload request could take several minutes to\n         finalize. After Amazon S3 begins processing the request, it sends an HTTP response header that\n         specifies a <code>200 OK</code> response. While processing is in progress, Amazon S3\n         periodically sends white space characters to keep the connection from timing out. A request\n         could fail after the initial <code>200 OK</code> response has been sent. This means that a\n            <code>200 OK</code> response can contain either a success or an error. The error\n         response might be embedded in the <code>200 OK</code> response. If you call this API\n         operation directly, make sure to design your application to parse the contents of the\n         response and handle it appropriately. If you use Amazon Web Services SDKs, SDKs handle this condition.\n         The SDKs detect the embedded error and apply error handling per your configuration settings\n         (including automatically retrying the request as appropriate). If the condition persists,\n         the SDKs throw an exception (or, for the SDKs that don't use exceptions, they return an\n         error). </p>\n         <p>Note that if <code>CompleteMultipartUpload</code> fails, applications should be prepared\n         to retry any failed requests (including 500 error responses).

Also, if you don't provide a <code>Content-Type</code>\n            header, <code>CompleteMultipartUpload</code> can still return a <code>200 OK</code>\n            response.</p>\n         </important>\n         <p>For more information about multipart uploads, see <a href=\"https://docs.aws.amazon.com/AmazonS3/latest/dev/uploadobjusingmpu.html\">Uploading Objects Using Multipart\n            Upload</a> in the <i>Amazon S3 User Guide</i>.</p>\n         <note>\n            <p>\n               <b>Directory buckets</b> -\n            For directory buckets, you must make requests for this API operation to the Zonal endpoint.

Specifically, you grant the <code>s3express:CreateSession</code> permission to the directory bucket in a bucket policy or an IAM identity-based policy. Then, you make the <code>CreateSession</code> API call on the bucket to obtain a session token. With the session token in your request header, you can make API requests to this operation. After the session token expires, you make another <code>CreateSession</code> API call to generate a new session token for use. \nAmazon Web Services CLI or SDKs create session and refresh the session token automatically to avoid service interruptions when a session expires.

When doing a multipart upload, if you don't specify encryption\n                        information in your request, the encryption setting of the uploaded parts is\n                        set to the default encryption configuration of the destination bucket. By\n                        default, all buckets have a base level of encryption configuration that uses\n                        server-side encryption with Amazon S3 managed keys (SSE-S3). If the destination\n                        bucket has a default encryption configuration that uses server-side\n                        encryption with an Key Management Service (KMS) key (SSE-KMS), or a customer-provided\n                        encryption key (SSE-C), Amazon S3 uses the corresponding KMS key, or a\n                        customer-provided key to encrypt the uploaded parts. When you perform a\n                        CreateMultipartUpload operation, if you want to use a different type of\n                        encryption setting for the uploaded parts, you can request that Amazon S3\n                        encrypts the object with a different encryption key (such as an Amazon S3 managed\n                        key, a KMS key, or a customer-provided key). When the encryption setting\n                        in your request is different from the default encryption configuration of\n                        the destination bucket, the encryption setting in your request takes\n                        precedence.
