What?

An alternate easy to use AWS cli for some specific daily needs.

It basically provides functions that I need frequently.

Install

pip install eyws

Permissions Required

list-costs and email-costs require you to enable Cost Explorer first on the console and give following permissions:

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Sid": "VisualEditor0",
            "Effect": "Allow",
            "Action": [
                "ce:GetReservationUtilization",
                "ce:GetDimensionValues",
                "ce:GetCostAndUsage",
                "ce:GetTags"
            ],
            "Resource": "*"
        }
    ]
}

AWSConfigRoleForOrganizations is optional for appending organization information to usage costs.

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Sid": "VisualEditor0",
            "Effect": "Allow",
            "Action": "organizations:DescribeOrganization",
            "Resource": "*"
        }
    ]
}

Keep in mind that each paginated Cost Explorer API request will cost you $0.01 (Learn more).

list-instances, list-zones, list-regions, list-images, list-key-pairs, list-sec-groups require:

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Sid": "VisualEditor0",
            "Effect": "Allow",
            "Action": [
                "ec2:DescribeInstances",
                "ec2:DescribeAvailabilityZones",
                "ec2:DescribeRegions",
                "ec2:DescribeImages",                                                
                "ec2:DescribeKeyPairs",
                "ec2:DescribeSecurityGroups"
            ],
            "Resource": "*"
        }
