{{% notice info %}}
Cloud9 normally manages IAM credentials dynamically. This isn't currently compatible with
the EKS IAM authentication, so we will disable it and rely on the IAM role instead.
{{% /notice %}}

- Return to your workspace and click the gear icon (in top right corner), or click to open a new tab and choose "Open Preferences"
- Select **AWS SETTINGS**
- Turn off **AWS managed temporary credentials**
- Close the Preferences tab
![c9disableiam](/images/c9disableiam.png)

To ensure temporary credentials aren't already in place we will also remove
any existing credentials file:
```sh
rm -vf ${HOME}/.aws/credentials
```

We should configure our aws cli with our current region as default.

{{% notice info %}}
If you are [at an AWS event](https://eksworkshop.com/020_prerequisites/aws_event/), ask your instructor which **AWS region** to use.
{{% /notice %}}

```sh
# install jq 
sudo yum install jq
```

Then, export the ACCOUNT_ID and AWS_REGION as variables:

```sh
export ACCOUNT_ID=$(aws sts get-caller-identity --output text --query Account) &&\
export AWS_REGION=$(curl -s 169.254.169.254/latest/dynamic/instance-identity/document | jq -r '.region')
```

Check if AWS_REGION is set to desired region

```sh
test -n "$AWS_REGION" && echo AWS_REGION is "$AWS_REGION" || echo AWS_REGION is not set
```

Let's save these into bash_profile

```sh
echo "export ACCOUNT_ID=${ACCOUNT_ID}" | tee -a ~/.bash_profile
echo "export AWS_REGION=${AWS_REGION}" | tee -a ~/.bash_profile
aws configure set default.region ${AWS_REGION}
aws configure get default.region
```

### Validate the IAM role

Use the [GetCallerIdentity](https://docs.aws.amazon.com/cli/latest/reference/sts/get-caller-identity.html) CLI command to validate that the Cloud9 IDE is using the correct IAM role.

Just run this to try it out yourself.

```sh
aws sts get-caller-identity
```

Here is a script that will validate you have the right role.

```sh
aws sts get-caller-identity --query Arn | grep mod- -q && echo "IAM role valid" || echo "IAM role NOT valid"
```

If the IAM role is not valid, <span style="color: red;">**DO NOT PROCEED**</span>. Go back and confirm the steps on this page.
