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/"
}

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

Example 1: To create an IAM role

The following create-role command creates a role named Test-Role and attaches a trust policy to it.

aws iam create-role \
    --role-name Test-Role \
    --assume-role-policy-document file://Test-Role-Trust-Policy.json

Output:

{
    "Role": {
        "AssumeRolePolicyDocument": "<URL-encoded-JSON>",
        "RoleId": "AKIAIOSFODNN7EXAMPLE",
        "CreateDate": "2013-06-07T20:43:32.821Z",
        "RoleName": "Test-Role",
        "Path": "/",
        "Arn": "arn:aws:iam::123456789012:role/Test-Role"
    }
}

The trust policy is defined as a JSON document in the Test-Role-Trust-Policy.json file. (The file name and extension do not have significance.) The trust policy must specify a principal.

To attach a permissions policy to a role, use the put-role-policy command.

For more information, see Creating IAM roles in the Amazon IAM User Guide.

Example 2: To create an IAM role with specified maximum session duration

The following create-role command creates a role named Test-Role and sets a maximum session duration of 7200 seconds (2 hours).

aws iam create-role \
    --role-name Test-Role \
    --assume-role-policy-document file://Test-Role-Trust-Policy.json \
    --max-session-duration 7200

Output:

        "Path": "/",
        "RoleName": "Test-Role",
        "RoleId": "AKIAIOSFODNN7EXAMPLE",

Example 3: To create an IAM Role with tags

The following command creates an IAM Role Test-Role with tags. This example uses the --tags parameter flag with the following JSON-formatted tags: '{"Key": "Department", "Value": "Accounting"}' '{"Key": "Location", "Value": "Seattle"}'. Alternatively, the --tags flag can be used with tags in the shorthand format: 'Key=Department,Value=Accounting Key=Location,Value=Seattle'.

aws iam create-role \
    --role-name Test-Role \
    --assume-role-policy-document file://Test-Role-Trust-Policy.json \
    --tags '{"Key": "Department", "Value": "Accounting"}' '{"Key": "Location", "Value": "Seattle"}'

Output:

{
    "Role": {
        "Path": "/",
        "RoleName": "Test-Role",
        "RoleId": "AKIAIOSFODNN7EXAMPLE",

                }
            ]
        },
        "Tags": [
            {

Example 1: This example creates a new role named MyNewRole and attaches to it the policy found in the file NewRoleTrustPolicy.json. Note that you must use the -Raw switch parameter to successfully process the JSON policy file. The policy document displayed in the output is URL encoded. It is decoded in this example with the UrlDecode .NET method.

$results = New-IAMRole -AssumeRolePolicyDocument (Get-Content -raw NewRoleTrustPolicy.json) -RoleName MyNewRole
$results
