### Deployments

CodeDeploy for ECS can manage the deployment of new task definitions to ECS services.  Only 1 deployment construct can be defined for a given EcsDeploymentGroup.

```python
declare const deploymentGroup: codeDeploy.IEcsDeploymentGroup;
declare const taskDefinition: ecs.ITaskDefinition;

new EcsDeployment({
  deploymentGroup,
  targetService: {
    taskDefinition,
    containerName: 'mycontainer',
    containerPort: 80,
  },
});
```

The deployment will use the AutoRollbackConfig for the EcsDeploymentGroup unless it is overridden in the deployment:

```python
new EcsDeployment({
  deploymentGroup,
  targetService: {
    taskDefinition,
    containerName: 'mycontainer',
    containerPort: 80,
  },
  autoRollback: {
    failedDeployment: true,
    deploymentInAlarm: true,
    stoppedDeployment: false,
  },
});
```

By default, the deployment will timeout after 30 minutes. The timeout value can be overridden:

```python
new EcsDeployment({
  deploymentGroup,
  targetService: {
    taskDefinition,
    containerName: 'mycontainer',
    containerPort: 80,
  },
  timeout: Duration.minutes(60),
});
```

### API Canaries

CodeDeploy can leverage Cloudwatch Alarms to trigger automatic rollbacks. The `ApiCanary` construct simplifies the process for creating CloudWatch Synthetics Canaries to monitor APIs. The following code demonstrates a canary that monitors https://xkcd.com/908/info.0.json and checks the JSON response to assert that `safe_title` has the value of `'The Cloud'`.

```python
const canary = new ApiCanary(stack, 'Canary', {
  baseUrl: 'https://xkcd.com',
  durationAlarmThreshold: Duration.seconds(5),
  threadCount: 5,
  steps: [
    {
      name: 'info',
      path: '/908/info.0.json',
      jmesPath: 'safe_title',
      expectedValue: 'The Cloud',
    },
  ],
});
```

### Application Load Balanced CodeDeployed Fargate Service

An L3 construct named `ApplicationLoadBalancedCodeDeployedFargateService` extends [ApplicationLoadBalancedFargateService](https://docs.aws.amazon.com/cdk/api/v2/docs/aws-cdk-lib.aws_ecs_patterns.ApplicationLoadBalancedFargateService.html) and adds support for deploying new versions of the service with AWS CodeDeploy. Additionally, an Amazon CloudWatch Synthetic canary is created via the `ApiCanary` construct and is monitored by the CodeDeploy deployment to trigger rollback if the canary begins to alarm.

```python
declare const cluster: ecs.ICluster;
declare const image: ecs.ContainerImage;
const service = new ApplicationLoadBalancedCodeDeployedFargateService(stack, 'Service', {
  cluster,
  taskImageOptions: {
    image,
  },
  apiTestSteps: [{
    name: 'health',
    path: '/health',
    jmesPath: 'status',
    expectedValue: 'ok',
  }],
});
```

## Local Development

```bash
yarn install
yarn build
yarn test
```

To run an integration test and update the snapshot, run:

```bash
yarn integ:ecs-deployment:deploy
```

To recreate snapshots for integration tests, run:

```bash
yarn integ:snapshot-all
```
