Fargate Linux platform version change log

The following are the available Linux platform versions. For information about platform version deprecation, see Amazon Fargate Linux platform version deprecation.

The following is the changelog for platform version 1.4.0.

  • Beginning on November 5, 2020, any new Amazon ECS task launched on Fargate using platform version 1.4.0 will be able to use the following features:

    • When using Secrets Manager to store sensitive data, you can inject a specific JSON key or a specific version of a secret as an environment variable or in a log configuration. For more information, see Pass sensitive data to an Amazon ECS container.

    • Specify environment variables in bulk using the environmentFiles container definition parameter. For more information, see Pass an individual environment variable to an Amazon ECS container.

    • Tasks run in a VPC and subnet enabled for IPv6 will be assigned both a private IPv4 address and an IPv6 address. For more information, see Fargate task networking in the Amazon Elastic Container Service User Guide for Amazon Fargate.

    • The task metadata endpoint version 4 provides additional metadata about your task and container including the task launch type, the Amazon Resource Name (ARN) of the container, and the log driver and log driver options used. When querying the /stats endpoint you also receive network rate stats for your containers. For more information, see Task metadata endpoint version 4.

  • Beginning on July 30, 2020, any new Amazon ECS task launched on Fargate using platform version 1.4.0 will be able to route UDP traffic using a Network Load Balancer to their Amazon ECS on Fargate tasks. For more information, see Use load balancing to distribute Amazon ECS service traffic.

  • Beginning on May 28, 2020, any new Amazon ECS task launched on Fargate using platform version 1.4.0 will have its ephemeral storage encrypted with an AES-256 encryption algorithm using an Amazon owned encryption key. For more information, see Fargate task ephemeral storage for Amazon ECS and Storage options for Amazon ECS tasks.

  • Added support for using Amazon EFS file system volumes for persistent task storage. For more information, see Use Amazon EFS volumes with Amazon ECS.

  • The ephemeral task storage has been increased to a minimum of 20 GB for each task. For more information, see Fargate task ephemeral storage for Amazon ECS.

  • The network traffic behavior to and from tasks has been updated. Starting with platform version 1.4.0, all Fargate tasks receive a single elastic network interface (referred to as the task ENI) and all network traffic flows through that ENI within your VPC and will be visible to you through your VPC flow logs. For more information about networking for the Amazon EC2 launch type, see Fargate Task Networking. For more information about networking for the Fargate launch type, see Amazon ECS task networking options for the Fargate launch type.

  • Task ENIs add support for jumbo frames. Network interfaces are configured with a maximum transmission unit (MTU), which is the size of the largest payload that fits within a single frame. The larger the MTU, the more application payload can fit within a single frame, which reduces per-frame overhead and increases efficiency. Supporting jumbo frames will reduce overhead when the network path between your task and the destination supports jumbo frames, such as all traffic that remains within your VPC.

  • CloudWatch Container Insights will include network performance metrics for Fargate tasks. For more information, see Monitor Amazon ECS containers using Container Insights.

  • Added support for the task metadata endpoint version 4 which provides additional information for your Fargate tasks, including network stats for the task and which Availability Zone the task is running in. For more information, see >Amazon ECS task metadata endpoint version 4 and Amazon ECS task metadata endpoint version 4 for tasks on Fargate.

  • Added support for the SYS_PTRACE Linux parameter in container definitions. For more information, see Linux parameters.

  • The Fargate container agent replaces the use of the Amazon ECS container agent for all Fargate tasks. Usually, this change does not have an effect on how your tasks run.

  • The container runtime is now using Containerd instead of Docker. Most likely, this change does not have an effect on how your tasks run. You will notice that some error messages that originate with the container runtime changes from mentioning Docker to more general errors. For more information, see Stopped tasks error codes in the Amazon Elastic Container Service User Guide for Amazon Fargate.

  • Based on Amazon Linux 2.

The following is the changelog for platform version 1.3.0.

  • Beginning on Sept 30, 2019, any new Fargate task that is launched supports the awsfirelens log driver. Configure the FireLens for Amazon ECS to use task definition parameters to route logs to an Amazon service or Amazon Partner Network (APN) destination for log storage and analytics. For more information, see Send Amazon ECS logs to an Amazon service or Amazon Partner.

  • Added task recycling for Fargate tasks, which is the process of refreshing tasks that are a part of an Amazon ECS service. For more information, Task maintenance in the Amazon Elastic Container Service User Guide for Amazon Fargate.

  • Beginning on March 27, 2019, any new Fargate task that is launched can use additional task definition parameters that you use to define a proxy configuration, dependencies for container startup and shutdown as well as a per-container start and stop timeout value. For more information, see Proxy configuration, Container dependency, and Container timeouts.

  • Beginning on April 2, 2019, any new Fargate task that is launched supports injecting sensitive data into your containers by storing your sensitive data in either Amazon Secrets Manager secrets or Amazon Systems Manager Parameter Store parameters and then referencing them in your container definition. For more information, see Pass sensitive data to an Amazon ECS container.

  • Beginning on May 1, 2019, any new Fargate task that is launched supports referencing sensitive data in the log configuration of a container using the secretOptions container definition parameter. For more information, see Pass sensitive data to an Amazon ECS container.

  • Beginning on May 1, 2019, any new Fargate task that is launched supports the splunk log driver in addition to the awslogs log driver. For more information, see Storage and logging.

  • Beginning on July 9, 2019, any new Fargate tasks that is launched supports CloudWatch Container Insights. For more information, see Monitor Amazon ECS containers using Container Insights.

  • Beginning on December 3, 2019, the Fargate Spot capacity provider is supported. For more information, see Amazon ECS clusters for the Fargate launch type .

  • Based on Amazon Linux 2.
