CDK Construct library for higher-level ECS Constructs

This library provides higher-level Amazon ECS constructs which follow common architectural patterns. It contains:

  • Application Load Balanced Services
  • Network Load Balanced Services
  • Queue Processing Services
  • Scheduled Tasks (cron jobs)
  • Additional Examples

Application Load Balanced Services

To define an Amazon ECS service that is behind an application load balancer, instantiate one of the following:

  • ApplicationLoadBalancedEc2Service
var cluster cluster

loadBalancedEcsService := ecsPatterns.NewApplicationLoadBalancedEc2Service(this, jsii.String("Service"), &applicationLoadBalancedEc2ServiceProps{
	cluster: cluster,
	memoryLimitMiB: jsii.Number(1024),
	taskImageOptions: &applicationLoadBalancedTaskImageOptions{
		image: ecs.containerImage.fromRegistry(jsii.String("test")),
		environment: map[string]*string{
			"TEST_ENVIRONMENT_VARIABLE1": jsii.String("test environment variable 1 value"),
			"TEST_ENVIRONMENT_VARIABLE2": jsii.String("test environment variable 2 value"),
		},
	},
	desiredCount: jsii.Number(2),
})
  • ApplicationLoadBalancedFargateService
var cluster cluster

loadBalancedFargateService := ecsPatterns.NewApplicationLoadBalancedFargateService(this, jsii.String("Service"), &applicationLoadBalancedFargateServiceProps{
	cluster: cluster,
	memoryLimitMiB: jsii.Number(1024),
	cpu: jsii.Number(512),
	taskImageOptions: &applicationLoadBalancedTaskImageOptions{
		image: ecs.containerImage.fromRegistry(jsii.String("amazon/amazon-ecs-sample")),
	},
})

loadBalancedFargateService.targetGroup.configureHealthCheck(&healthCheck{
	path: jsii.String("/custom-health-path"),
})

Instead of providing a cluster you can specify a VPC and CDK will create a new ECS cluster. If you deploy multiple services CDK will only create one cluster per VPC.

You can omit cluster and vpc to let CDK create a new VPC with two AZs and create a cluster inside this VPC.

You can customize the health check for your target group; otherwise it defaults to HTTP over port 80 hitting path /.

Fargate services will use the LATEST platform version by default, but you can override by providing a value for the platformVersion property in the constructor.

Fargate services use the default VPC Security Group unless one or more are provided using the securityGroups property in the constructor.

By setting redirectHTTP to true, CDK will automatically create a listener on port 80 that redirects HTTP traffic to the HTTPS port.

If you specify the option recordType you can decide if you want the construct to use CNAME or Route53-Aliases as record sets.

If you need to encrypt the traffic between the load balancer and the ECS tasks, you can set the targetProtocol to HTTPS.

Additionally, if more than one application target group are needed, instantiate one of the following:

  • ApplicationMultipleTargetGroupsEc2Service
// One application load balancer with one listener and two target groups.
var cluster cluster

loadBalancedEc2Service := ecsPatterns.NewApplicationMultipleTargetGroupsEc2Service(this, jsii.String("Service"), &applicationMultipleTargetGroupsEc2ServiceProps{
	cluster: cluster,
	memoryLimitMiB: jsii.Number(256),
	taskImageOptions: &applicationLoadBalancedTaskImageProps{
		image: ecs.containerImage.fromRegistry(jsii.String("amazon/amazon-ecs-sample")),
	},
	targetGroups: []applicationTargetProps{
		&applicationTargetProps{
			containerPort: jsii.Number(80),
		},
		&applicationTargetProps{
			containerPort: jsii.Number(90),
			pathPattern: jsii.String("a/b/c"),
			priority: jsii.Number(10),
		},
	},
})
  • ApplicationMultipleTargetGroupsFargateService
// One application load balancer with one listener and two target groups.
var cluster cluster

loadBalancedFargateService := ecsPatterns.NewApplicationMultipleTargetGroupsFargateService(this, jsii.String("Service"), &applicationMultipleTargetGroupsFargateServiceProps{
	cluster: cluster,
	memoryLimitMiB: jsii.Number(1024),
	cpu: jsii.Number(512),
	taskImageOptions: &applicationLoadBalancedTaskImageProps{
		image: ecs.containerImage.fromRegistry(jsii.String("amazon/amazon-ecs-sample")),
	},
	targetGroups: []applicationTargetProps{
		&applicationTargetProps{
			containerPort: jsii.Number(80),
		},
		&applicationTargetProps{
			containerPort: jsii.Number(90),
			pathPattern: jsii.String("a/b/c"),
			priority: jsii.Number(10),
		},
	},
})

Network Load Balanced Services

To define an Amazon ECS service that is behind a network load balancer, instantiate one of the following:

  • NetworkLoadBalancedEc2Service
var cluster cluster

loadBalancedEcsService := ecsPatterns.NewNetworkLoadBalancedEc2Service(this, jsii.String("Service"), &networkLoadBalancedEc2ServiceProps{
	cluster: cluster,
	memoryLimitMiB: jsii.Number(1024),
	taskImageOptions: &networkLoadBalancedTaskImageOptions{
		image: ecs.containerImage.fromRegistry(jsii.String("test")),
		environment: map[string]*string{
			"TEST_ENVIRONMENT_VARIABLE1": jsii.String("test environment variable 1 value"),
			"TEST_ENVIRONMENT_VARIABLE2": jsii.String("test environment variable 2 value"),
		},
	},
	desiredCount: jsii.Number(2),
})
  • NetworkLoadBalancedFargateService
var cluster cluster

loadBalancedFargateService := ecsPatterns.NewNetworkLoadBalancedFargateService(this, jsii.String("Service"), &networkLoadBalancedFargateServiceProps{
	cluster: cluster,
	memoryLimitMiB: jsii.Number(1024),
	cpu: jsii.Number(512),
	taskImageOptions: &networkLoadBalancedTaskImageOptions{
		image: ecs.containerImage.fromRegistry(jsii.String("amazon/amazon-ecs-sample")),
	},
})

The CDK will create a new Amazon ECS cluster if you specify a VPC and omit cluster. If you deploy multiple services the CDK will only create one cluster per VPC.

If cluster and vpc are omitted, the CDK creates a new VPC with subnets in two Availability Zones and a cluster within this VPC.

If you specify the option recordType you can decide if you want the construct to use CNAME or Route53-Aliases as record sets.

Additionally, if more than one network target group is needed, instantiate one of the following:

  • NetworkMultipleTargetGroupsEc2Service
// Two network load balancers, each with their own listener and target group.
var cluster cluster

loadBalancedEc2Service := ecsPatterns.NewNetworkMultipleTargetGroupsEc2Service(this, jsii.String("Service"), &networkMultipleTargetGroupsEc2ServiceProps{
	cluster: cluster,
	memoryLimitMiB: jsii.Number(256),
	taskImageOptions: &networkLoadBalancedTaskImageProps{
		image: ecs.containerImage.fromRegistry(jsii.String("amazon/amazon-ecs-sample")),
	},
	loadBalancers: []networkLoadBalancerProps{
		&networkLoadBalancerProps{
			name: jsii.String("lb1"),
			listeners: []networkListenerProps{
				&networkListenerProps{
					name: jsii.String("listener1"),
				},
			},
		},
		&networkLoadBalancerProps{
			name: jsii.String("lb2"),
			listeners: []*networkListenerProps{
				&networkListenerProps{
					name: jsii.String("listener2"),
				},
			},
		},
	},
	targetGroups: []networkTargetProps{
		&networkTargetProps{
			containerPort: jsii.Number(80),
			listener: jsii.String("listener1"),
		},
		&networkTargetProps{
			containerPort: jsii.Number(90),
			listener: jsii.String("listener2"),
		},
	},
})
  • NetworkMultipleTargetGroupsFargateService
// Two network load balancers, each with their own listener and target group.
var cluster cluster

loadBalancedFargateService := ecsPatterns.NewNetworkMultipleTargetGroupsFargateService(this, jsii.String("Service"), &networkMultipleTargetGroupsFargateServiceProps{
	cluster: cluster,
	memoryLimitMiB: jsii.Number(512),
	taskImageOptions: &networkLoadBalancedTaskImageProps{
		image: ecs.containerImage.fromRegistry(jsii.String("amazon/amazon-ecs-sample")),
	},
	loadBalancers: []networkLoadBalancerProps{
		&networkLoadBalancerProps{
			name: jsii.String("lb1"),
			listeners: []networkListenerProps{
				&networkListenerProps{
					name: jsii.String("listener1"),
				},
			},
		},
		&networkLoadBalancerProps{
			name: jsii.String("lb2"),
			listeners: []*networkListenerProps{
				&networkListenerProps{
					name: jsii.String("listener2"),
				},
			},
		},
	},
	targetGroups: []networkTargetProps{
		&networkTargetProps{
			containerPort: jsii.Number(80),
			listener: jsii.String("listener1"),
		},
		&networkTargetProps{
			containerPort: jsii.Number(90),
			listener: jsii.String("listener2"),
		},
	},
})

Queue Processing Services

To define a service that creates a queue and reads from that queue, instantiate one of the following:

  • QueueProcessingEc2Service
var cluster cluster

queueProcessingEc2Service := ecsPatterns.NewQueueProcessingEc2Service(this, jsii.String("Service"), &queueProcessingEc2ServiceProps{
	cluster: cluster,
	memoryLimitMiB: jsii.Number(1024),
	image: ecs.containerImage.fromRegistry(jsii.String("test")),
	command: []*string{
		jsii.String("-c"),
		jsii.String("4"),
		jsii.String("amazon.com"),
	},
	enableLogging: jsii.Boolean(false),
	desiredTaskCount: jsii.Number(2),
	environment: map[string]*string{
		"TEST_ENVIRONMENT_VARIABLE1": jsii.String("test environment variable 1 value"),
		"TEST_ENVIRONMENT_VARIABLE2": jsii.String("test environment variable 2 value"),
	},
	maxScalingCapacity: jsii.Number(5),
	containerName: jsii.String("test"),
})
  • QueueProcessingFargateService
var cluster cluster

queueProcessingFargateService := ecsPatterns.NewQueueProcessingFargateService(this, jsii.String("Service"), &queueProcessingFargateServiceProps{
	cluster: cluster,
	memoryLimitMiB: jsii.Number(512),
	image: ecs.containerImage.fromRegistry(jsii.String("test")),
	command: []*string{
		jsii.String("-c"),
		jsii.String("4"),
		jsii.String("amazon.com"),
	},
	enableLogging: jsii.Boolean(false),
	desiredTaskCount: jsii.Number(2),
	environment: map[string]*string{
		"TEST_ENVIRONMENT_VARIABLE1": jsii.String("test environment variable 1 value"),
		"TEST_ENVIRONMENT_VARIABLE2": jsii.String("test environment variable 2 value"),
	},
	maxScalingCapacity: jsii.Number(5),
	containerName: jsii.String("test"),
})

when queue not provided by user, CDK will create a primary queue and a dead letter queue with default redrive policy and attach permission to the task to be able to access the primary queue.

Scheduled Tasks

To define a task that runs periodically, there are 2 options:

  • ScheduledEc2Task
// Instantiate an Amazon EC2 Task to run at a scheduled interval
var cluster cluster

ecsScheduledTask := ecsPatterns.NewScheduledEc2Task(this, jsii.String("ScheduledTask"), &scheduledEc2TaskProps{
	cluster: cluster,
	scheduledEc2TaskImageOptions: &scheduledEc2TaskImageOptions{
		image: ecs.containerImage.fromRegistry(jsii.String("amazon/amazon-ecs-sample")),
		memoryLimitMiB: jsii.Number(256),
		environment: map[string]*string{
			"name": jsii.String("TRIGGER"),
			"value": jsii.String("CloudWatch Events"),
		},
	},
	schedule: appscaling.schedule.expression(jsii.String("rate(1 minute)")),
	enabled: jsii.Boolean(true),
	ruleName: jsii.String("sample-scheduled-task-rule"),
})
  • ScheduledFargateTask
var cluster cluster

scheduledFargateTask := ecsPatterns.NewScheduledFargateTask(this, jsii.String("ScheduledFargateTask"), &scheduledFargateTaskProps{
	cluster: cluster,
	scheduledFargateTaskImageOptions: &scheduledFargateTaskImageOptions{
		image: ecs.containerImage.fromRegistry(jsii.String("amazon/amazon-ecs-sample")),
		memoryLimitMiB: jsii.Number(512),
	},
	schedule: appscaling.schedule.expression(jsii.String("rate(1 minute)")),
	platformVersion: ecs.fargatePlatformVersion_LATEST,
})

Use the REMOVE_DEFAULT_DESIRED_COUNT feature flag

The REMOVE_DEFAULT_DESIRED_COUNT feature flag is used to override the default desiredCount that is autogenerated by the CDK. This will set the desiredCount of any service created by any of the following constructs to be undefined.

  • ApplicationLoadBalancedEc2Service
  • ApplicationLoadBalancedFargateService
  • NetworkLoadBalancedEc2Service
  • NetworkLoadBalancedFargateService
  • QueueProcessingEc2Service
  • QueueProcessingFargateService

If a desiredCount is not passed in as input to the above constructs, CloudFormation will either create a new service to start up with a desiredCount of 1, or update an existing service to start up with the same desiredCount as prior to the update.

To enable the feature flag, ensure that the REMOVE_DEFAULT_DESIRED_COUNT flag within an application stack context is set to true, like so:

var stack stack

stack.node.setContext(cxapi.eCS_REMOVE_DEFAULT_DESIRED_COUNT, jsii.Boolean(true))

The following is an example of an application with the REMOVE_DEFAULT_DESIRED_COUNT feature flag enabled:

import "github.com/aws/aws-cdk-go/awscdk"
import ec2 "github.com/aws/aws-cdk-go/awscdk"
import ecs "github.com/aws/aws-cdk-go/awscdk"
import ecsPatterns "github.com/aws/aws-cdk-go/awscdk"
import cxapi "github.com/aws/aws-cdk-go/awscdk"
import path "github.com/aws-samples/dummy/path"

app := awscdk.NewApp()

stack := awscdk.NewStack(app, jsii.String("aws-ecs-patterns-queue"))
stack.node.setContext(cxapi.eCS_REMOVE_DEFAULT_DESIRED_COUNT, jsii.Boolean(true))

vpc := ec2.NewVpc(stack, jsii.String("VPC"), &vpcProps{
	maxAzs: jsii.Number(2),
})

ecsPatterns.NewQueueProcessingFargateService(stack, jsii.String("QueueProcessingService"), &queueProcessingFargateServiceProps{
	vpc: vpc,
	memoryLimitMiB: jsii.Number(512),
	image: ecs.NewAssetImage(path.join(__dirname, jsii.String(".."), jsii.String("sqs-reader"))),
})
Deploy application and metrics sidecar

The following is an example of deploying an application along with a metrics sidecar container that utilizes dockerLabels for discovery:

var cluster cluster
var vpc vpc

service := ecsPatterns.NewApplicationLoadBalancedFargateService(this, jsii.String("Service"), &applicationLoadBalancedFargateServiceProps{
	cluster: cluster,
	vpc: vpc,
	desiredCount: jsii.Number(1),
	taskImageOptions: &applicationLoadBalancedTaskImageOptions{
		image: ecs.containerImage.fromRegistry(jsii.String("amazon/amazon-ecs-sample")),
		dockerLabels: map[string]*string{
			"application.label.one": jsii.String("first_label"),
			"application.label.two": jsii.String("second_label"),
		},
	},
})

service.taskDefinition.addContainer(jsii.String("Sidecar"), &containerDefinitionOptions{
	image: ecs.*containerImage.fromRegistry(jsii.String("example/metrics-sidecar")),
})
Select specific load balancer name ApplicationLoadBalancedFargateService
var cluster cluster

loadBalancedFargateService := ecsPatterns.NewApplicationLoadBalancedFargateService(this, jsii.String("Service"), &applicationLoadBalancedFargateServiceProps{
	cluster: cluster,
	memoryLimitMiB: jsii.Number(1024),
	desiredCount: jsii.Number(1),
	cpu: jsii.Number(512),
	taskImageOptions: &applicationLoadBalancedTaskImageOptions{
		image: ecs.containerImage.fromRegistry(jsii.String("amazon/amazon-ecs-sample")),
	},
	taskSubnets: &subnetSelection{
		subnets: []iSubnet{
			ec2.subnet.fromSubnetId(this, jsii.String("subnet"), jsii.String("VpcISOLATEDSubnet1Subnet80F07FA0")),
		},
	},
	loadBalancerName: jsii.String("application-lb-name"),
})
ECS Exec

You can use ECS Exec to run commands in or get a shell to a container running on an Amazon EC2 instance or on AWS Fargate. Enable ECS Exec, by setting enableExecuteCommand to true.

ECS Exec is supported by all Services i.e. ApplicationLoadBalanced(Fargate|Ec2)Service, ApplicationMultipleTargetGroups(Fargate|Ec2)Service, NetworkLoadBalanced(Fargate|Ec2)Service, NetworkMultipleTargetGroups(Fargate|Ec2)Service, QueueProcessing(Fargate|Ec2)Service. It is not supported for ScheduledTasks.

Read more about ECS Exec in the ECS Developer Guide.

Example:

var cluster cluster

loadBalancedFargateService := ecsPatterns.NewApplicationLoadBalancedFargateService(this, jsii.String("Service"), &applicationLoadBalancedFargateServiceProps{
	cluster: cluster,
	memoryLimitMiB: jsii.Number(1024),
	desiredCount: jsii.Number(1),
	cpu: jsii.Number(512),
	taskImageOptions: &applicationLoadBalancedTaskImageOptions{
		image: ecs.containerImage.fromRegistry(jsii.String("amazon/amazon-ecs-sample")),
	},
	enableExecuteCommand: jsii.Boolean(true),
})

Please note, ECS Exec leverages AWS Systems Manager (SSM). So as a prerequisite for the exec command to work, you need to have the SSM plugin for the AWS CLI installed locally. For more information, see Install Session Manager plugin for AWS CLI.

Functions

func ApplicationLoadBalancedEc2Service_IsConstruct 

func ApplicationLoadBalancedEc2Service_IsConstruct(x interface{}) *bool

Checks if `x` is a construct.

Use this method instead of `instanceof` to properly detect `Construct` instances, even when the construct library is symlinked.

Explanation: in JavaScript, multiple copies of the `constructs` library on disk are seen as independent, completely different libraries. As a consequence, the class `Construct` in each copy of the `constructs` library is seen as a different class, and an instance of one class will not test as `instanceof` the other class. `npm install` will not create installations like this, but users may manually symlink construct libraries together or use a monorepo tool: in those cases, multiple copies of the `constructs` library can be accidentally installed, and `instanceof` will behave unpredictably. It is safest to avoid using `instanceof`, and using this type-testing method instead.

Returns: true if `x` is an object created from a class which extends `Construct`.

It is safest to avoid using `instanceof`, and using this type-testing method instead.

Returns: true if `x` is an object created from a class which extends `Construct`.

func QueueProcessingServiceBase_IsConstruct 

func QueueProcessingServiceBase_IsConstruct(x interface{}) *bool

Checks if `x` is a construct.

Use this method instead of `instanceof` to properly detect `Construct` instances, even when the construct library is symlinked.
