Pulumi Amazon Machine Image Helpers

Don't hard-code your AMIs, and don't copy and paste JSON/YAML maps! Use this package instead.

For instance, rather than copy and pasting this into every program you create:

``typescript
import * as aws from "@pulumi/aws";

const instanceTypeToArch: {[instanceType: string]: string} = {
"t1.micro" : "PV64" ,
"t2.nano" : "HVM64",
"t2.micro" : "HVM64",
"t2.small" : "HVM64",
"t2.medium" : "HVM64",
"t2.large" : "HVM64",
// etc, etc, etc
};

const regionArchToAmi: {[region: string]: {[arch: string]: string}} = {
"us-east-1" : {"PV64" : "ami-2a69aa47", "HVM64" : "ami-97785bed", "HVMG2" : "ami-0a6e3770"},
"us-west-2" : {"PV64" : "ami-7f77b31f", "HVM64" : "ami-f2d3638a", "HVMG2" : "ami-ee15a196"},
"us-west-1" : {"PV64" : "ami-a2490dc2", "HVM64" : "ami-824c4ee2", "HVMG2" : "ami-0da4a46d"},
"eu-west-1" : {"PV64" : "ami-4cdd453f", "HVM64" : "ami-d834aba1", "HVMG2" : "ami-af8013d6"},
"eu-west-2" : {"PV64" : "NOT_SUPPORTED", "HVM64" : "ami-403e2524", "HVMG2" : "NOT_SUPPORTED"},
// etc, etc, etc
};

export function getLinuxAmi(region: aws.Region, instanceType: aws.ec2.InstanceType): string {
let arch = instanceTypeToArch[instanceType];
let archToAmi = regionArchToAmi[region];
return archToAmi[arch];
}

let vm = new aws.ec2.Instance("webserver", {
ami: getLinuxAmi(..., ...),
});
`

and dealing with it being constantly out of date (missing regions, instance types, or outdated AMIs), you can simply
call this library:

`typescript
import * as aws from "@pulumi/aws";
import * as pawsami from "pawsami";

let vm = new aws.ec2.Instance("webserver, {
ami: pawsami.getLinuxAmi(..., ...),
});
