CLI

AWS CLI

Example 1: To create a bucket

The following create-bucket example creates a bucket named my-bucket:


aws s3api create-bucket \
    --bucket my-bucket \
    --region us-east-1

Output:


{
    "Location": "/my-bucket"
}

For more information, see Creating a bucket in the Amazon S3 User Guide.

Example 2: To create a bucket with owner enforced

The following create-bucket example creates a bucket named my-bucket that uses the bucket owner enforced setting for S3 Object Ownership.


aws s3api create-bucket \
    --bucket my-bucket \
    --region us-east-1 \
    --object-ownership BucketOwnerEnforced

Output:


{
    "Location": "/my-bucket"
}

For more information, see Controlling ownership of objects and disabling ACLs in the Amazon S3 User Guide.

Example 3: To create a bucket outside of the ``us-east-1`` region

The following create-bucket example creates a bucket named my-bucket in the eu-west-1 region. Regions outside of us-east-1 require the appropriate LocationConstraint to be specified in order to create the bucket in the desired region.


aws s3api create-bucket \
    --bucket my-bucket \
    --region eu-west-1 \
    --create-bucket-configuration LocationConstraint=eu-west-1

Output:


{
    "Location": "http://my-bucket.s3.amazonaws.com/"
}
