How can I create a AWS cluster by specifying the launch configuration using CDK-CodePudding

I am using aws cdk to create my cluster. From the console I can define the autoscaling group relying on a launch template/configuration which points to a AMI.

How can I do that with AWS CDK?

this.cluster = new ecs.Cluster(this, "myCluster", {
      vpc: this.vpc,
    });

this.cluster.addCapacity("myASG", {
        instanceType: new ec2.InstanceType("t3.medium"),
        desiredCapacity: 8,
        minCapacity: 1,
        maxCapacity: 8,
      });

I am wondering if this is a good way?

create an autoScallingGroup by specifying the launch configuration name, and create a capacity provider by using the autoScalingGroup, add the capcity provider to the cluster.

CodePudding user response：

If you want full control over the autoscaling group configuration, create the ASG and add it to the cluster.

// Or add customized capacity. Be sure to start the Amazon ECS-optimized AMI.
const autoScalingGroup = new autoscaling.AutoScalingGroup(this, 'ASG', {
  vpc,
  instanceType: new ec2.InstanceType('t2.xlarge'),
  machineImage: ecs.EcsOptimizedImage.amazonLinux(),
  // Or use Amazon ECS-Optimized Amazon Linux 2 AMI
  // machineImage: EcsOptimizedImage.amazonLinux2(),
  desiredCapacity: 3,
  // ... other options here ...
});

cluster.addAutoScalingGroup(autoScalingGroup);
