#### [ CLI ]
**AWS CLI**
**To describe IAM instance profile associations**
This example describes all of your IAM instance profile associations.
Command:
```
aws ec2 describe-iam-instance-profile-associations
```
Output:
```
{
"IamInstanceProfileAssociations": [
{
"InstanceId": "i-09eb09efa73ec1dee",
"State": "associated",
