What you will need 🔨

Assuming that you already have your AWS credentials in /.aws file.

create a .env file and set the role arn as env vars,to switch roles properly:

     role_prod=arn:aws:iam::123456:role/ProdblablaViewOnllyFULL-sadlp43
     role_stage=arn:aws:iam::14324324:role/StageblablaViewOnlyFULL-34234
     role_old=arn:aws:iam::21231:role/OldblablaFullAccess-214324
     role_auth=arn:aws:iam::109267741677:role/AuthblablaFullViewacase24

Output Interface 📜

    [count] x Instances: 
    {
        "Name": "instanceName",
        "Endpoint": {
            "Address": "address",
            "Port": 5432
        },
        "Engine": "postgres:11.5"
    }, ...
       

- Above is what expected in output terminal and instances.log file for each service listed.

• May not print in the same order cause go routine can terminate in diferent times.
