Amazon ECS Container Agent Versions

Each Amazon ECS container agent version supports a different feature set and provides bug fixes from previous versions. When possible, we always recommend using the latest version of the Amazon ECS container agent. To update your container agent to the latest version, see Updating the Amazon ECS Container Agent.

Launching your container instances from the most recent Amazon ECS-optimized AMI ensures that you receive the current container agent version. To launch a container instance with the latest Amazon ECS-optimized AMI, see Launching an Amazon ECS Container Instance.

To install the latest version of the Amazon ECS container agent on another operating system, see Installing the Amazon ECS Container Agent. The table in Amazon ECS-optimized AMI Container Agent Versions shows the Docker version that is tested on Amazon Linux for each agent version.

To see which features and enhancements are included with each agent release, see https://github.com/aws/amazon-ecs-agent/releases.

Amazon ECS-optimized AMI Container Agent Versions

The Amazon ECS-optimized AMI comes prepackaged with the Amazon ECS container agent, Docker, and the ecs-init service that controls the starting and stopping of the agent at boot and shutdown. The following table lists the container agent version, the ecs-init version, and the Docker version that is tested and packaged with each Amazon ECS-optimized AMI.

Note

As new Amazon ECS-optimized AMIs and Amazon ECS agent versions are released, older versions are still available for launch in Amazon EC2; however, we encourage you to update to the latest version of the Amazon ECS agent and to keep your container instance software up to date. If you request support for an older version of the Amazon ECS agent through AWS Support, you may be asked to move to the latest version as a part of the support process.
