Does AWS CDK provide constructs to deploy ECS applications using rolling deployments?

[shamhub]

We generally use BlueGreen & Rolling deployment strategy to deploy/update docker containers in ECS container instances.

---

Ansible ECS modules allow implement such deployment strategies(rolling deployment) with below modules:

https://docs.ansible.com/ansible/latest/modules/ecs_taskdefinition_module.html

https://docs.ansible.com/ansible/latest/modules/ecs_task_module.html

https://docs.ansible.com/ansible/latest/modules/ecs_service_module.html

Hey @shamhub Native blue/green deployment requires support from the Cloudformation service side and we are actively working on it. You can find the tracking issue here.

Hey @shamhub so I suppose you would like to see both blue/green & rolling deployments? I will contact our product team regarding the second deployment strategy and get back to you.

Priority wise... I would like to see "Roling deployment" first and then "B/G deployment" next

[hencrice]

For rolling update, I think this is what you want: https://docs.aws.amazon.com/cdk/api/latest/docs/@aws-cdk_aws-ecs.DeploymentControllerType.html.

You can specify the deployment controller type when creating a service construct: https://docs.aws.amazon.com/cdk/api/latest/docs/@aws-cdk_aws-ecs.Ec2Service.html

@shamhub hopefully that answers your question

@hencrice now that support for ECS blue/green this has been added to CFN, can we expect to see this functionality available in CDK soon?

Hey there, we are working to implement this. Gonna close this in favor of #1559.

Check this NPM plugin which helps with blue-green deployment using CDK.
