#### [ CLI ]

**AWS CLI**  
**To add a role to an instance profile**  
The following `add-role-to-instance-profile` command adds the role named `S3Access` to the instance profile named `Webserver`.  

```
aws iam add-role-to-instance-profile \
    --role-name S3Access \
    --instance-profile-name Webserver
```
This command produces no output.  
To create an instance profile, use the `create-instance-profile` command.  
For more information, see [Using an IAM role to grant permissions to applications running on Amazon EC2 instances](https://docs.aws.amazon.com/IAM/latest/UserGuide/id_roles_use_switch-role-ec2.html) in the *AWS IAM User Guide*.

#### [ PowerShell ]

**Tools for PowerShell V4**  
**Example 1: This command adds the role named `S3Access` to an existing instance profile named `webserver`. To create the instance profile, use the `New-IAMInstanceProfile` command. After you create the instance profile and associate it with a role using this command, you can attach it to an EC2 instance. To do that, use the `New-EC2Instance` cmdlet with either the `InstanceProfile_Arn` or the `InstanceProfile-Name` parameter to launch the new instance.**  

```
Add-IAMRoleToInstanceProfile -RoleName "S3Access" -InstanceProfileName "webserver"
```
+  For API details, see [AddRoleToInstanceProfile](https://docs.aws.amazon.com/powershell/v4/reference) in *AWS Tools for PowerShell Cmdlet Reference (V4)*. 

**Tools for PowerShell V5**  
**Example 1: This command adds the role named `S3Access` to an existing instance profile named `webserver`. To create the instance profile, use the `New-IAMInstanceProfile` command. After you create the instance profile and associate it with a role using this command, you can attach it to an EC2 instance. To do that, use the `New-EC2Instance` cmdlet with either the `InstanceProfile_Arn` or the `InstanceProfile-Name` parameter to launch the new instance.**  

```
Add-IAMRoleToInstanceProfile -RoleName "S3Access" -InstanceProfileName "webserver"
