To read Instance Metadata, you dont need to configure the AWS CLI. The problem in your case, is you are using a wrong URL to read the Instance Metadata. The correct URL to use is http://169.254.169.254/ . For example, if you want to read the AMI id of the Instance, you can use the follow command.
curl http://169.254.169.254/latest/meta-data/ami-id
However, if you would like to configure the AWS cli without using the Access/Secret Keys. Follow the below steps.
Create an IAM instance profile and Attach it to the EC2 instance
- Open the IAM console at https://console.aws.amazon.com/iam/.
- In the navigation pane, choose Roles, Create role.
- On the Select role type page, choose EC2 and the EC2 use case. Choose Next: Permissions.
- On the Attach permissions policy page, select an AWS managed policy that
grants your instances access to the resources that they need.
- On the Review page, type a name for the role and choose Create role.
Install the AWS CLI(Ubuntu).
Install pip if it is not installed already.
`sudo apt-get install python-pip`
Install AWS CLI.
`pip install awscli --upgrade --user`
Configure the AWS CLI. Leave AWS Access Key ID and AWS Secret Access
Key as blank as we want to use a Role.
$ aws configure
AWS Access Key ID [None]:
AWS Secret Access Key [None]:
Default region name [None]: us-west-2
Default output format [None]: json
Modify the Region and Output Format values if required.
I hope this Helps you!
