Method Details
-
getCapabilities
The Linux capabilities for the container that are added to or dropped from the default configuration provided by Docker.For tasks that use the Fargate launch type,
capabilities
is supported for all platform versions but theadd
parameter is only supported if using platform version 1.4.0 or later.- See Also:
-
getDevices
Any host devices to expose to the container.This parameter maps to
Devices
in the docker container create command and the--device
option to docker run.If you're using tasks that use the Fargate launch type, the
devices
parameter isn't supported.- See Also:
-
getInitProcessEnabled
Run aninit
process inside the container that forwards signals and reaps processes.This parameter maps to the
--init
option to docker run. This parameter requires version 1.25 of the Docker Remote API or greater on your container instance. To check the Docker Remote API version on your container instance, log in to your container instance and run the following command:sudo docker version --format '{{.Server.APIVersion}}'
- See Also:
-
getMaxSwap
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 themaxSwap
value.If a
maxSwap
value of0
is specified, the container will not use swap. Accepted values are0
or any positive integer. If themaxSwap
parameter is omitted, the container will use the swap configuration for the container instance it is running on. AmaxSwap
value must be set for theswappiness
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.- See Also:
-
getSwappiness
This allows you to tune a container's memory swappiness behavior.A
swappiness
value of0
will cause swapping to not happen unless absolutely necessary. Aswappiness
value of100
will cause pages to be swapped very aggressively. Accepted values are whole numbers between0
and100
. If theswappiness
parameter is not specified, a default value of60
is used. If a value is not specified formaxSwap
then this parameter is ignored. This parameter maps to the--memory-swappiness
option to docker run.If you're using tasks that use the Fargate launch type, the
swappiness
parameter isn't supported.If you're using tasks on Amazon Linux 2023 the
swappiness
parameter isn't supported.- See Also:
-
getTmpfs
The container path, mount options, and size (in MiB) of the tmpfs mount.This parameter maps to the
--tmpfs
option to docker run.If you're using tasks that use the Fargate launch type, the
tmpfs
parameter isn't supported.- See Also:
