maxSwap

val maxSwap: Int?

The total amount of swap memory (in MiB) a container can use. This parameter will be translated to the --memory-swap option to docker run where the value would be the sum of the container memory plus the maxSwap value.

If a maxSwap value of 0 is specified, the container will not use swap. Accepted values are 0 or any positive integer. If the maxSwap parameter is omitted, the container will use the swap configuration for the container instance it is running on. A maxSwap value must be set for the swappiness parameter to be used.

If you're using tasks that use the Fargate launch type, the maxSwap parameter isn't supported.

If you're using tasks on Amazon Linux 2023 the swappiness parameter isn't supported.
