AWS::ECS::TaskDefinition SystemControl

A list of namespaced kernel parameters to set in the container. This parameter maps to Sysctls in the Create a container section of the Docker Remote API and the --sysctl option to docker run.

It is not recommended that you specify network-related systemControls parameters for multiple containers in a single task that also uses either the awsvpc or host network mode for the following reasons:

• For tasks that use the awsvpc network mode, if you set systemControls for any container, it applies to all containers in the task. If you set different systemControls for multiple containers in a single task, the container that is started last determines which systemControls take effect.

• For tasks that use the host network mode, the systemControls parameter applies to the container instance's kernel parameter as well as that of all containers of any tasks running on that container instance.
