Are you stuck with an “Access Denied” error when trying to delete a role from an instance profile in AWS? You’re not alone! This frustrating issue can leave even the most seasoned cloud engineers scratching their heads. But fear not, dear reader, for we’ve got the solution right here. In this article, we’ll dive into the root cause of the problem, and provide step-by-step instructions to get you back on track.
Understanding the Problem
Before we dive into the fix, let’s first understand what’s causing the “Access Denied” error. When you try to delete a role from an instance profile, AWS performs a series of checks to ensure the role is eligible for deletion. One of these checks involves verifying the role’s associations with other AWS resources, such as EC2 instances, Lambda functions, and Elastic Container Service (ECS) clusters.
If the role is still associated with one or more resources, AWS will prevent the deletion to avoid any potential disruptions. However, if you’re certain the role is no longer being used, you’ll need to dissociate it from these resources before deletion.
Step 1: Identify Associated Resources
The first step in resolving the “Access Denied” error is to identify the resources associated with the role. You can do this using the AWS CLI or the AWS Management Console.
aws iam list-entities-for-policy --policy-arn --entity-type ROLE
Replace with the ARN of the role you want to delete. This command will return a list of resources associated with the role.
AWS Management Console Method
If you prefer a visual approach, you can use the AWS Management Console to identify associated resources.
1. Log in to the AWS Management Console and navigate to the IAM dashboard.
2. Click on “Roles” in the left-hand menu and select the role you want to delete.
3. Scroll down to the “Permissions” tab and click on “Policy usage.”
4. In the “Policy usage” tab, you’ll see a list of resources associated with the role.
Step 2: Dissociate Resources from the Role
Now that you’ve identified the associated resources, it’s time to dissociate them from the role. This process varies depending on the type of resource.
EC2 Instances
To dissociate an EC2 instance from a role, follow these steps:
1. Log in to the AWS Management Console and navigate to the EC2 dashboard.
2. Select the instance associated with the role and click “Actions” > “Instance settings.”
3. In the “Instance settings” page, click on “Edit” next to “IAM role.”
4. Select “None” as the IAM role and click “Save.”
Lambda Functions
To dissociate a Lambda function from a role, follow these steps:
1. Log in to the AWS Management Console and navigate to the Lambda dashboard.
2. Select the Lambda function associated with the role and click “Configuration” tab.
3. In the “Configuration” tab, click on “Edit” next to “Execution role.”
4. Select “None” as the execution role and click “Save.”
ECS Clusters
To dissociate an ECS cluster from a role, follow these steps:
1. Log in to the AWS Management Console and navigate to the ECS dashboard.
2. Select the ECS cluster associated with the role and click “Clusters” > “Edit.”
3. In the “Edit cluster” page, click on “Edit” next to “Execution role ARN.”
4. Remove the role ARN and click “Save.”
Step 3: Delete the Role
Once you’ve dissociated all resources from the role, you can delete it using the AWS CLI or the AWS Management Console.
aws iam delete-role --role-name
Replace with the name of the role you want to delete.
AWS Management Console Method
If you prefer a visual approach, you can use the AWS Management Console to delete the role.
1. Log in to the AWS Management Console and navigate to the IAM dashboard.
2. Click on “Roles” in the left-hand menu and select the role you want to delete.
3. Click the “Delete role” button.
4. Confirm the deletion by clicking “Delete.”
Troubleshooting Tips
If you’re still encountering issues when trying to delete the role, here are some troubleshooting tips to keep in mind:
- Ensure you have the necessary permissions to delete the role. You may need to verify your IAM credentials or ask your administrator for assistance.
- Check if there are any other resources associated with the role that you haven’t dissociated yet. Use the AWS CLI or the AWS Management Console to identify any remaining associations.
- If you’re using a third-party service that’s associated with the role, ensure you’ve disconnected the service from the role before deletion.
- Try deleting the role using the AWS CLI instead of the AWS Management Console, or vice versa. Sometimes, one method may work when the other doesn’t.
Conclusion
Deleting a role from an instance profile can be a complex process, especially when you’re faced with an “Access Denied” error. By following the steps outlined in this article, you should be able to dissociate the role from associated resources and delete it successfully. Remember to take a methodical approach, and don’t hesitate to reach out if you need further assistance. Happy cloud engineering!
| Resource | Dissociation Method |
|---|---|
| EC2 Instance | Update instance settings, set IAM role to None |
| Lambda Function | Update function configuration, set execution role to None |
| ECS Cluster | Update cluster settings, remove execution role ARN |
aws iam list-entities-for-policy --policy-arn arn:aws:iam::123456789012:policy/MyPolicy --entity-type ROLE
{
"Entities": [
{
"EntityArn": "arn:aws:iam::123456789012:role/MyRole",
"EntityType": "ROLE"
}
]
}
By following these steps and troubleshooting tips, you should be able to resolve the “Access Denied” error and delete the role from the instance profile. Remember to stay vigilant and methodical in your approach, and don’t hesitate to reach out if you need further assistance.

Frequently Asked Question
Are you stuck with deleting a role from an instance profile and getting an “Access Denied” error? Don’t worry, we’ve got you covered! Here are some frequently asked questions and answers to help you resolve the issue.
Why am I getting an “Access Denied” error while deleting a role from an instance profile?
This error usually occurs when the IAM user or role trying to delete the role from the instance profile doesn’t have the necessary permissions. Make sure the IAM user or role has the “iam:PassRole” and “iam:DeleteRole” permissions. You can also check if the role is still attached to an instance or a service and detach it before deleting the role.
How do I detach a role from an instance before deleting it?
To detach a role from an instance, go to the AWS Management Console, navigate to the IAM dashboard, and select “Roles” from the sidebar. Find the role you want to detach and click on it. Then, click on the “Instance profiles” tab and select the instance profile that has the role attached. Click the “Detach” button to detach the role from the instance profile. Once detached, you can delete the role.
What if I’m still getting the “Access Denied” error after ensuring I have the necessary permissions?
In this case, check if there are any active sessions or tokens associated with the role. If there are, try revoking them using the AWS CLI command “aws iam revoke-token” or by going to the AWS Management Console, navigating to the IAM dashboard, and selecting “Roles” from the sidebar. Find the role and click on it, then click on the “Security credentials” tab and revoke any active sessions or tokens.
Can I delete a role from an instance profile using AWS CLI?
Yes, you can! Use the AWS CLI command “aws iam delete-instance-profile” followed by the name of the instance profile and the role you want to delete. For example, “aws iam delete-instance-profile –instance-profile-name MyInstanceProfile –role-name MyRole”. Make sure you have the necessary permissions and the role is not attached to any instances or services.
What are some best practices to avoid “Access Denied” errors when deleting roles from instance profiles?
Some best practices include using least privilege access, regularly reviewing and updating IAM roles and policies, using IAM conditions to restrict access, and testing IAM roles and policies in a non-production environment before applying them to production. Additionally, always follow the principle of least privilege when creating IAM roles and policies to minimize the risk of “Access Denied” errors.
