Example

declare const vpc: ec2.Vpc;

const cluster = new ecs.Cluster(this, 'Cluster', { vpc });

const securityGroup = new ec2.SecurityGroup(this, 'SecurityGroup', {
  vpc,
  description: 'Security group for managed instances',
});

const miCapacityProvider = new ecs.ManagedInstancesCapacityProvider(this, 'MICapacityProvider', {
  capacityOptionType: ecs.CapacityOptionType.SPOT,
  subnets: vpc.privateSubnets,
  securityGroups: [securityGroup],
  instanceRequirements: {
    vCpuCountMin: 1,
    memoryMin: Size.gibibytes(2),
  },
});

// Optionally configure security group rules using IConnectable interface
miCapacityProvider.connections.allowFrom(ec2.Peer.ipv4(vpc.vpcCidrBlock), ec2.Port.tcp(80));

// Add the capacity provider to the cluster
cluster.addManagedInstancesCapacityProvider(miCapacityProvider);

const taskDefinition = new ecs.TaskDefinition(this, 'TaskDef', {
  memoryMiB: '512',
  cpu: '256',
  networkMode: ecs.NetworkMode.AWS_VPC,
  compatibility: ecs.Compatibility.MANAGED_INSTANCES,
});

taskDefinition.addContainer('web', {
  image: ecs.ContainerImage.fromRegistry('amazon/amazon-ecs-sample'),
  memoryReservationMiB: 256,
});

new ecs.FargateService(this, 'FargateService', {
  cluster,
  taskDefinition,
  minHealthyPercent: 100,
  capacityProviderStrategies: [
    {
      capacityProvider: miCapacityProvider.capacityProviderName,
      weight: 1,
    },
  ],
