              awslogs-stream-prefix: ecs
          Memory: !Ref TaskMemory

Validate task definition syntax before proceeding:

4. Configure Execution Roles

Set up IAM roles for task execution:

Resources:
  ExecutionRole:
    Type: AWS::IAM::Role
    Properties:
      AssumeRolePolicyDocument:
        Version: "2012-10-17"
        Statement:

                  - s3:GetObject
                Resource: !Sub "${DataBucket.Arn}/*"

5. Create ECS Service

Define the service configuration:

Resources:
  ECSService:
    Type: AWS::ECS::Service
    Properties:
      ServiceName: !Sub "${AWS::StackName}-service"
      Cluster: !Ref ECSCluster
      TaskDefinition: !Ref TaskDefinition
      DesiredCount: 2
      LaunchType: FARGATE
      NetworkConfiguration:
        AwsvpcConfiguration:
          Subnets:
            - !Ref PrivateSubnet1
            - !Ref PrivateSubnet2
          SecurityGroups:
            - !Ref SecurityGroup
          AssignPublicIp: DISABLED
      LoadBalancers:
        - TargetGroupArn: !Ref TargetGroup
          ContainerName: application
          ContainerPort: !Ref ContainerPort

6. Configure Load Balancer

Set up ALB for traffic distribution:

Resources:
  LoadBalancer:
    Type: AWS::ElasticLoadBalancingV2::LoadBalancer
    Properties:
      Name: !Sub "${AWS::StackName}-alb"
      Scheme: internet-facing
      Type: application
      Subnets:
        - !Ref PublicSubnet1
        - !Ref PublicSubnet2
      SecurityGroups:
        - !Ref ALBSecurityGroup

  TargetGroup:
    Type: AWS::ElasticLoadBalancingV2::TargetGroup
    Properties:
      Port: 80
      Protocol: HTTP
      VpcId: !Ref VPC
      TargetType: ip

  Listener:
    Type: AWS::ElasticLoadBalancingV2::Listener
    Properties:
      DefaultActions:
        - TargetGroupArn: !Ref TargetGroup
          Type: forward
      LoadBalancerArn: !Ref LoadBalancer
      Port: 80
      Protocol: HTTP

7. Implement Auto Scaling

Configure Application Auto Scaling:

Resources:
  ScalableTarget:
    Type: AWS::ApplicationAutoScaling::ScalableTarget
    Properties:
      MaxCapacity: 10
      MinCapacity: 1
      ResourceId: !Sub "service/${ECSCluster}/${ECSService}"
      ScalableDimension: ecs:service:DesiredCount
      ServiceNamespace: ecs

  ScalingPolicy:
    Type: AWS::ApplicationAutoScaling::ScalingPolicy
    Properties:
      PolicyName: !Sub "${AWS::StackName}-scaling"
      PolicyType: TargetTrackingScaling
      ScalingTargetId: !Ref ScalableTarget
      TargetTrackingScalingPolicyConfiguration:
        TargetValue: 70.0
        PredefinedMetricSpecification:
          PredefinedMetricType: ECSServiceAverageCPUUtilization

8. Configure Monitoring

Enable CloudWatch Container Insights:

Resources:
  LogGroup:
    Type: AWS::Logs::LogGroup
    Properties:
      LogGroupName: !Sub "/ecs/${AWS::StackName}"
      RetentionInDays: 7

Before deployment: Create a change set to preview changes:

aws cloudformation create-change-set \
  --stack-name my-ecs-stack \
  --template-body file://template.yaml \
  --change-set-type CREATE
aws cloudformation execute-change-set --change-set-name <arn>

Best Practices

Task Definition

Use Family naming for version tracking and immutable deployments
Keep task definition under 1 KB (CloudFormation limit) by referencing external configs
Configure HealthCheck in container definitions for ECS health monitoring
Set both Cpu and Memory at task level for Fargate

Service Deployment

Enable DeploymentCircuitBreaker for automatic rollback on failures
Use HealthCheckGracePeriodSeconds matching application startup time
Configure MinimumHealthyPercent (100) and MaximumPercent (200) for zero-downtime updates
Reference task definition by logical ID only—ECS automatically uses latest revision

Networking

Always use awsvpc network mode for Fargate
Place tasks in private subnets with NAT gateway for outbound access
Configure security groups to allow only required ports (not 0.0.0.0/0)

Scaling

Use Fargate Spot with base capacity of 1 on-demand for cost optimization
Set MaxHealthyDuration on capacity provider strategy for Spot interruption handling
Monitor STEADY_STATE failures in CloudWatch for task startup issues

Constraints and Warnings

Resource Limits

Task definition size limit: 1 KB when using CloudFormation (use ParameterStore/Secrets Manager for large configs)
Maximum 10 containers per task definition in Fargate
CPU must be specified for Fargate tasks (256-4096 units, in 1024 increments)
Memory must be allocated (512-30720 MB depending on CPU)

Operational Limits

ENI limits apply per subnet—plan for at least 1 ENI per task in each AZ
Fargate Spot tasks receive 2-minute interruption notice—implement graceful shutdown signals (SIGTERM)
Service updates require new task definition revision—cannot modify existing versions
DesiredCount updates during deployment may conflict with auto scaling policies

CloudFormation-Specific

Cross-stack references required for VPC IDs, Subnet IDs, and Security Group IDs passed between stacks
Use !GetAtt for referencing stack outputs in same template
Ensure IAM role ARNs use Fn::Sub with stack name for portability

  --stack-name my-ecs-stack \
  --template-body file://template.yaml \
  --change-set-type CREATE
aws cloudformation execute-change-set --change-set-name <arn>
```
