CapacityProvider

Source: src/AWS/ECS/CapacityProvider.ts

An Amazon ECS capacity provider backed by an EC2 Auto Scaling Group.

Capacity providers are associated with one or more ECS clusters via {@link Cluster#capacityProviders} and are referenced by a service or task’s capacity provider strategy.

Only EC2 Auto Scaling Group-backed capacity providers are currently supported. The reserved AWS providers FARGATE and FARGATE_SPOT do not need to be created and can be referenced by name on a Cluster directly.

Creating Capacity Providers

const provider = yield* CapacityProvider("AppCapacityProvider", {
  autoScalingGroupArn: asg.autoScalingGroupArn,
  managedScaling: {
    status: "ENABLED",
    targetCapacity: 80,
    minimumScalingStepSize: 1,
    maximumScalingStepSize: 10,
  },
  managedTerminationProtection: "ENABLED",
});

yield* Cluster("AppCluster", {
  capacityProviders: [provider.name],
  defaultCapacityProviderStrategy: [
    { capacityProvider: provider.name, weight: 1 },
  ],
});

Adopting Existing Capacity Providers

import { adopt } from "alchemy/AdoptPolicy";

yield* CapacityProvider("AppCapacityProvider", {
  name: "existing-provider",
  autoScalingGroupArn: asg.autoScalingGroupArn,
}).pipe(adopt());
