Create IAM Users

This workshop has been deprecated and archived. The new Amazon EKS Workshop is now available at

In order to test our scenarios, we will create 3 users, one for each groups we created :

aws iam create-user --user-name PaulAdmin
aws iam create-user --user-name JeanDev
aws iam create-user --user-name PierreInteg

Add users to associated groups:

aws iam add-user-to-group --group-name k8sAdmin --user-name PaulAdmin
aws iam add-user-to-group --group-name k8sDev --user-name JeanDev
aws iam add-user-to-group --group-name k8sInteg --user-name PierreInteg

Check users are correctly added in their groups:

aws iam get-group --group-name k8sAdmin
aws iam get-group --group-name k8sDev
aws iam get-group --group-name k8sInteg

For the sake of simplicity, in this chapter, we will save credentials to a file to make it easy to toggle back and forth between users. Never do this in production or with credentials that have priviledged access; It is not a security best practice to store credentials on the filesystem.

Retrieve Access Keys for our fake users:

aws iam create-access-key --user-name PaulAdmin | tee /tmp/PaulAdmin.json
aws iam create-access-key --user-name JeanDev | tee /tmp/JeanDev.json
aws iam create-access-key --user-name PierreInteg | tee /tmp/PierreInteg.json


  • PaulAdmin is in the k8sAdmin group and will be able to assume the k8sAdmin role.
  • JeanDev is in k8sDev Group and will be able to assume IAM role k8sDev
  • PierreInteg is in k8sInteg group and will be able to assume IAM role k8sInteg
