public interface LinuxParametersProps
extends software.amazon.jsii.JsiiSerializable

The properties for defining Linux-specific options that are applied to the container.

Example:

 // Example automatically generated from non-compiling source. May contain errors.
 TaskDefinition taskDefinition;
 taskDefinition.addContainer("container", ContainerDefinitionOptions.builder()
         .image(ContainerImage.fromRegistry("amazon/amazon-ecs-sample"))

Method Detail

getInitProcessEnabled

@Stability(value=Stable)
 @Nullable
default Boolean getInitProcessEnabled()

Specifies whether to run an init process inside the container that forwards signals and reaps processes.

Default: false

getMaxSwap

@Stability(value=Stable)
 @Nullable
default Size getMaxSwap()

The total amount of swap memory a container can use.

This parameter will be translated to the --memory-swap option to docker run.

This parameter is only supported when you are using the EC2 launch type. Accepted values are positive integers.

Default: No swap.

getSharedMemorySize

@Stability(value=Stable)
 @Nullable
default Number getSharedMemorySize()

The value for the size of the /dev/shm volume.

Default: No shared memory.

getSwappiness

@Stability(value=Stable)
 @Nullable
default Number getSwappiness()

This allows you to tune a container's memory swappiness behavior.

This parameter maps to the --memory-swappiness option to docker run. The swappiness relates to the kernel's tendency to swap memory. A value of 0 will cause swapping to not happen unless absolutely necessary. A value of 100 will cause pages to be swapped very aggressively.

This parameter is only supported when you are using the EC2 launch type. Accepted values are whole numbers between 0 and 100. If a value is not specified for maxSwap then this parameter is ignored.

Default: 60

builder

@Stability(value=Stable)
static LinuxParametersProps.Builder builder()

Returns:

a LinuxParametersProps.Builder of LinuxParametersProps
