### 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
# deployment_group: codeDeploy.IEcsDeploymentGroup
# task_definition: ecs.ITaskDefinition
EcsDeployment(
deployment_group=deployment_group,
target_service=TargetService(
task_definition=task_definition,
container_name="mycontainer",
container_port=80
)
)
```
The deployment will use the AutoRollbackConfig for the EcsDeploymentGroup unless it is overridden in the deployment:
```python
# deployment_group: codeDeploy.IEcsDeploymentGroup
# task_definition: ecs.ITaskDefinition
EcsDeployment(
deployment_group=deployment_group,
target_service=TargetService(
task_definition=task_definition,
container_name="mycontainer",
container_port=80
),
auto_rollback=codeDeploy.AutoRollbackConfig(
failed_deployment=True,
deployment_in_alarm=True,
stopped_deployment=False
)
)
```
By default, the deployment will timeout after 30 minutes. The timeout value can be overridden:
```python
# deployment_group: codeDeploy.IEcsDeploymentGroup
# task_definition: ecs.ITaskDefinition
EcsDeployment(
deployment_group=deployment_group,
target_service=TargetService(
task_definition=task_definition,
container_name="mycontainer",
container_port=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
canary = ApiCanary(stack, "Canary",
base_url="https://xkcd.com",
duration_alarm_threshold=Duration.seconds(5),
thread_count=5,
steps=[ApiTestStep(
name="info",
path="/908/info.0.json",
jmes_path="safe_title",
expected_value="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
# cluster: ecs.ICluster
# image: ecs.ContainerImage
service = ApplicationLoadBalancedCodeDeployedFargateService(stack, "Service",
cluster=cluster,
task_image_options=ApplicationLoadBalancedTaskImageOptions(
image=image
),
api_test_steps=[ApiTestStep(
name="health",
path="/health",
jmes_path="status",
expected_value="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
```
