dependsOn

The dependencies defined for container startup and shutdown. A container can contain multiple dependencies. When a dependency is defined for container startup, for container shutdown it is reversed. For tasks using the EC2 launch type, the container instances require at least version 1.26.0 of the container agent to turn on container dependencies. However, we recommend using the latest container agent version. For information about checking your agent version and updating to the latest version, see Updating the Amazon ECS Container Agent in the Amazon Elastic Container Service Developer Guide. If you're using an Amazon ECS-optimized Linux AMI, your instance needs at least version 1.26.0-1 of the `ecs-init` package. If your container instances are launched from version `20190301` or later, then they contain the required versions of the container agent and `ecs-init`. For more information, see Amazon ECS-optimized Linux AMI in the Amazon Elastic Container Service Developer Guide. For tasks using the Fargate launch type, the task or service requires the following platforms:

• Linux platform version `1.3.0` or later.

• Windows platform version `1.0.0` or later. If the task definition is used in a blue/green deployment that uses AWS::CodeDeploy::DeploymentGroup BlueGreenDeploymentConfiguration, the `dependsOn` parameter is not supported. For more information see Issue #680 on the on the GitHub website.
