When you deploy containers with Amazon Elastic Container Service (Amazon ECS) Express Mode, Amazon ECS provides load balancing, scaling, logging, and networking without additional configuration. As your workload evolves, you may want to tailor this environment to your specific requirements. For example, you can access running containers with ECS Exec to troubleshoot issues, provision capacity ahead of predictable traffic spikes, or route application logs to the destination of your choice with FireLens. Because Express Mode creates standard AWS resources in your account, you can extend Express Mode using the same ECS APIs and other AWS service APIs you already use. This applies whether you are migrating from AWS App Runner or starting fresh. Express Mode also supports custom task definitions, allowing you to apply advanced task-level configurations such as sidecar containers, custom health checks, and FireLens for custom log routing, while keeping the simplified deployment experience. In this post, you walk through how to extend an Amazon ECS Express Mode service beyond its defaults, with three hands-on examples: turning on ECS Exec, adding a scheduled scaling policy, and adding a FireLens log router as a sidecar container using a custom task definition. You also learn which service-level settings Express Mode restricts and how to decide whether those restrictions affect your workload. Solution overview This section provides an overview of ECS Express Mode, the resources that Express Mode creates automatically, and the settings that you cannot change within it. …
