Buckets can be either defined within this stack:
new Bucket(this, 'MyBucket', { props });
Or imported from an existing bucket:
Bucket.import(this, 'MyImportedBucket', { bucketArn: ... });
You can also export a bucket and import it into another stack:
const ref = myBucket.export(); Bucket.import(this, 'MyImportedBucket', ref);

Methods
AddEventNotification(EventType, IBucketNotificationDestination, INotificationKeyFilter[])
Adds a bucket notification event destination.
public virtual void AddEventNotification(EventType event, IBucketNotificationDestination dest, params INotificationKeyFilter[] filters)Parameters
- event EventType
The event to trigger the notification.
- dest IBucketNotificationDestination
The notification destination (Lambda, SNS Topic or SQS Queue).
- filters INotificationKeyFilter[]
S3 object key filter rules to determine which objects trigger this event.
Remarks
Examples
Function myLambda;
Bucket bucket = new Bucket(this, "MyBucket");
bucket.AddEventNotification(EventType.OBJECT_CREATED, new LambdaDestination(myLambda), new NotificationKeyFilter { Prefix = "home/myusername/*" });AddObjectCreatedNotification(IBucketNotificationDestination, INotificationKeyFilter[])
Subscribes a destination to receive notifications when an object is created in the bucket.
public virtual void AddObjectCreatedNotification(IBucketNotificationDestination dest, params INotificationKeyFilter[] filters)Parameters
- dest IBucketNotificationDestination
The notification destination (see onEvent).
- filters INotificationKeyFilter[]
Filters (see onEvent).
Remarks
This is identical to calling
onEvent(EventType.OBJECT_CREATED).
AddObjectRemovedNotification(IBucketNotificationDestination, INotificationKeyFilter[])
Subscribes a destination to receive notifications when an object is removed from the bucket.
public virtual void AddObjectRemovedNotification(IBucketNotificationDestination dest, params INotificationKeyFilter[] filters)Parameters
- dest IBucketNotificationDestination
The notification destination (see onEvent).
- filters INotificationKeyFilter[]
Filters (see onEvent).
Remarks
This is identical to calling
onEvent(EventType.OBJECT_REMOVED).
AddToResourcePolicy(PolicyStatement)
Adds a statement to the resource policy for a principal (i.e. account/role/service) to perform actions on this bucket and/or its contents. Use bucketArn and arnForObjects(keys) to obtain ARNs for this bucket or objects.
public virtual IAddToResourcePolicyResult AddToResourcePolicy(PolicyStatement permission)Parameters
- permission PolicyStatement
the policy statement to be added to the bucket's policy.
Returns
metadata about the execution of this method. If the policy
was not added, the value of statementAdded will be false. You
should always check this value to make sure that the operation was
actually carried out. Otherwise, synthesis and deploy will terminate
silently, which may be confusing.
Remarks
Note that the policy statement may or may not be added to the policy.
For example, when an IBucket is created from an existing bucket,
it's not possible to tell whether the bucket already has a policy
attached, let alone to re-use that policy to add more statements to it.
So it's safest to do nothing in these cases.
ArnForObjects(String)
Returns an ARN that represents all objects within the bucket that match the key pattern specified.
public virtual string ArnForObjects(string keyPattern)Parameters
- keyPattern System.String
Returns
System.String
Remarks
To represent all keys, specify "*".
If you need to specify a keyPattern with multiple components, concatenate them into a single string, e.g.:
arnForObjects(home/${team}/${user}/*)
EnableEventBridgeNotification()
protected virtual void EnableEventBridgeNotification()GrantDelete(IGrantable, Object)
Grants s3:DeleteObject* permission to an IAM principal for objects in this bucket.
public virtual Grant GrantDelete(IGrantable identity, object objectsKeyPattern = null)Parameters
- identity IGrantable
The principal.
- objectsKeyPattern System.Object
Restrict the permission to a certain key pattern (default '*').
Returns
GrantPublicAccess(String, String[])
Allows unrestricted access to objects from this bucket.
public virtual Grant GrantPublicAccess(string keyPrefix = null, params string[] allowedActions)Parameters
- keyPrefix System.String
the prefix of S3 object keys (e.g.
home/*). Default is "*".- allowedActions System.String[]
the set of S3 actions to allow.
Returns
Remarks
IMPORTANT: This permission allows anyone to perform actions on S3 objects in this bucket, which is useful for when you configure your bucket as a website and want everyone to be able to read objects in the bucket without needing to authenticate.
Without arguments, this method will grant read ("s3:GetObject") access to all objects ("*") in the bucket.
The method returns the iam.Grant object, which can then be modified
as needed. For example, you can add a condition that will restrict access only
to an IPv4 range like this:
const grant = bucket.grantPublicAccess();
grant.resourceStatement!.addCondition(‘IpAddress’, { “aws:SourceIp”: “54.240.143.0/24” });Note that if this IBucket refers to an existing bucket, possibly not
managed by CloudFormation, this method will have no effect, since it's
impossible to modify the policy of an existing bucket.
GrantPut(IGrantable, Object)
Grants s3:PutObject* and s3:Abort* permissions for this bucket to an IAM principal.
public virtual Grant GrantPut(IGrantable identity, object objectsKeyPattern = null)Parameters
- identity IGrantable
The principal.
- objectsKeyPattern System.Object
Restrict the permission to a certain key pattern (default '*').
Returns
Remarks
If encryption is used, permission to use the key to encrypt the contents of written files will also be granted to the same principal.
GrantPutAcl(IGrantable, String)
Grant the given IAM identity permissions to modify the ACLs of objects in the given Bucket.
public virtual Grant GrantPutAcl(IGrantable identity, string objectsKeyPattern = null)Parameters
- identity IGrantable
- objectsKeyPattern System.String
Returns
Remarks
If your application has the '@aws-cdk/aws-s3:grantWriteWithoutAcl' feature flag set, calling {@link grantWrite} or {@link grantReadWrite} no longer grants permissions to modify the ACLs of the objects; in this case, if you need to modify object ACLs, call this method explicitly.
GrantRead(IGrantable, Object)
Grant read permissions for this bucket and it's contents to an IAM principal (Role/Group/User).
public virtual Grant GrantRead(IGrantable identity, object objectsKeyPattern = null)Parameters
- identity IGrantable
The principal.
- objectsKeyPattern System.Object
Restrict the permission to a certain key pattern (default '*').
Returns
Remarks
If encryption is used, permission to use the key to decrypt the contents of the bucket will also be granted to the same principal.
GrantReadWrite(IGrantable, Object)
Grants read/write permissions for this bucket and it's contents to an IAM principal (Role/Group/User).
public virtual Grant GrantReadWrite(IGrantable identity, object objectsKeyPattern = null)Parameters
- identity IGrantable
- objectsKeyPattern System.Object
Returns
Remarks
If an encryption key is used, permission to use the key for encrypt/decrypt will also be granted.
Before CDK version 1.85.0, this method granted the s3:PutObject* permission that included s3:PutObjectAcl,
which could be used to grant read/write object access to IAM principals in other accounts.
If you want to get rid of that behavior, update your CDK version to 1.85.0 or later,
and make sure the @aws-cdk/aws-s3:grantWriteWithoutAcl feature flag is set to true
in the context key of your cdk.json file.
If you've already updated, but still need the principal to have permissions to modify the ACLs,
use the {@link grantPutAcl} method.
GrantWrite(IGrantable, Object)
Grant write permissions to this bucket to an IAM principal.
public virtual Grant GrantWrite(IGrantable identity, object objectsKeyPattern = null)Parameters
- identity IGrantable
- objectsKeyPattern System.Object
Returns
Remarks
If encryption is used, permission to use the key to encrypt the contents of written files will also be granted to the same principal.
Before CDK version 1.85.0, this method granted the s3:PutObject* permission that included s3:PutObjectAcl,
which could be used to grant read/write object access to IAM principals in other accounts.
If you want to get rid of that behavior, update your CDK version to 1.85.0 or later,
and make sure the @aws-cdk/aws-s3:grantWriteWithoutAcl feature flag is set to true
in the context key of your cdk.json file.
If you've already updated, but still need the principal to have permissions to modify the ACLs,
use the {@link grantPutAcl} method.

- id System.String
The id of the rule.
- options IOnCloudTrailBucketEventOptions
Options for adding the rule.
Returns
Remarks
Note that some tools like aws s3 cp will automatically use either
PutObject or the multipart upload API depending on the file size,
so using onCloudTrailWriteObject may be preferable.
Requires that there exists at least one CloudTrail Trail in your account that captures the event. This method will not create the Trail.
OnCloudTrailWriteObject(String, IOnCloudTrailBucketEventOptions)
Defines an AWS CloudWatch event that triggers when an object at the specified paths (keys) in this bucket are written to.
