AWS introduces service versioning and deployment history for Amazon ECS services

Amazon Elastic Container Service (Amazon ECS) now allows you to view the service revision and deployment history for your long-running applications deployed as Amazon ECS services. This capability makes it easier for you to track and view changes to applications deployed using Amazon ECS, monitor on-going deployments, and debug deployment failures.

Typically, customers deploy long running applications as Amazon ECS services and deploy software updates using a rolling update mechanism where tasks running the old software version are gradually replaced by tasks running the new version. With today’s release, you can now view the deployment history for your Amazon ECS services on the AWS Management Console as well as using the new listServiceDeployments API. You can look at the details of a specific deployment, including whether it succeeded, when it started and completed, and service revision information before and after the deployment using the Console and describeServiceDeployment API. Furthermore, you can look at the immutable configuration for a specific service version, including the task definition, container image digests, load balancer, service connect configuration, etc. using the Console and describeServiceRevision API.

You can view the service version and deployment history for their services deployed on or after October 25, 2024 using the AWS Management Console, API, SDK, and CLI in all AWS Regions. To learn more, visit this blog post and documentation.
