Minimum IAM User Policy
- Wei Siong Siow
Owned by Wei Siong Siow
If you are using the example templates to spin up the infrastructure, the user who performs the installation must granted with minimum permission in order to be able to provision AWS resources.
You do not need to setup the following if the user that performs the installation has the AdministratorAccess policy.
For best practice it is preferably to set up a minimum IAM policy for the user to perform the installation.
For IAM user creation, please refer to AWS documentation for guidance https://docs.aws.amazon.com/IAM/latest/UserGuide/id_users_create.html.
The following table contains the policies required by the application.
