Service

Source: src/AWS/ECS/Service.ts

An ECS Fargate service for running long-lived tasks.

Service turns a bundled AWS.ECS.Task into a continuously running Fargate deployment with awsvpc networking. Phase 1 focuses on the public HTTP path, so the resource can optionally provision an Application Load Balancer, target group, and listener when public: true.

Creating Services

Public HTTP Service

const service = yield* Service("ApiService", {
  cluster,
  task: apiTask,
  vpcId: vpc.vpcId,
  subnets: [publicSubnet1.subnetId, publicSubnet2.subnetId],
  securityGroups: [serviceSecurityGroup.groupId],
  public: true,
});

Internal Service

const service = yield* Service("WorkerService", {
  cluster,
  task: workerTask,
  vpcId: vpc.vpcId,
  subnets: [privateSubnet1.subnetId, privateSubnet2.subnetId],
  securityGroups: [workerSecurityGroup.groupId],
  desiredCount: 2,
});

Public Ingress

const service = yield* Service("SecureApiService", {
  cluster,
  task: apiTask,
  vpcId: vpc.vpcId,
  subnets: [publicSubnet1.subnetId, publicSubnet2.subnetId],
  securityGroups: [serviceSecurityGroup.groupId],
  public: true,
  certificateArn,
  healthCheckPath: "/health",
});

Deployment

const service = yield* Service("ApiService", {
  cluster,
  task: apiTask,
  vpcId: vpc.vpcId,
  subnets: [publicSubnet1.subnetId, publicSubnet2.subnetId],
  securityGroups: [serviceSecurityGroup.groupId],
  public: true,
  desiredCount: 3,
  deploymentConfiguration: {
    minimumHealthyPercent: 100,
    maximumPercent: 200,
  },
  healthCheckGracePeriodSeconds: 30,
});
