LaunchTemplate

Source: src/AWS/AutoScaling/LaunchTemplate.ts

A launch template that preserves the Host authoring model used by AWS.EC2.Instance, but packages that host configuration for use with an Auto Scaling Group.

Creating a Launch Template

Basic Launch Template

import { LaunchTemplate } from "alchemy/AWS/AutoScaling";

const template = yield* LaunchTemplate("Template", {
  imageId: "ami-0abcdef1234567890",
  instanceType: "t3.micro",
});

Launch a fleet from the template

import { AutoScalingGroup } from "alchemy/AWS/AutoScaling";

const group = yield* AutoScalingGroup("Fleet", {
  launchTemplate: template,
  subnetIds: [subnet.subnetId],
  minSize: 1,
  maxSize: 3,
});

Hosting Processes

const template = yield* Effect.gen(function* () {
  yield* Http.serve(HttpServerResponse.json({ ok: true }));

  return {
    main: import.meta.url,
    imageId,
    instanceType: "t3.small",
    securityGroupIds: [securityGroup.groupId],
    port: 3000,
  };
}).pipe(
  Effect.provide(AWS.EC2.HttpServer),
  AWS.AutoScaling.LaunchTemplate("ApiTemplate"),
);
