Amazon ECS Express Mode now supports custom task definitions

Amazon Elastic Container Service (Amazon ECS) Express Mode now supports custom task definitions, giving you the flexibility to use existing ECS application configurations and advanced task-level customizations with Express Mode’s simplified deployment experience. This also enables you to reuse task definitions from your existing CI/CD pipelines and infrastructure-as-code workflows, allowing you to retain established operational practices while taking advantage of Express Mode’s streamlined application deployment and infrastructure automation.

ECS Express Mode makes it easy to deploy containerized web applications and APIs by automatically handling load balancing, networking, auto scaling, monitoring, and deployments. Now you can get the same simplicity for your own custom task definitions. With this update, you can extend Express Mode services with advanced task definition capabilities, including observability and security sidecars, custom container health checks, ulimits and Linux runtime settings, and FireLens for custom log routing. Once you associate a custom task definition with an Express Mode service, you can continue managing your application either through task definition updates or directly through Express Mode, whichever you prefer.

This feature is available in all AWS Regions. To get started, create or update your ECS Express Mode service by passing your task definition using the AWS Management Console, AWS CLI, AWS SDKs, or infrastructure-as-code tools.
