Properties
Devices
Any of the host devices to expose to the container.
public object? Devices { get; set; }
Property Value
Remarks
This parameter maps to Devices in the Create a container section of the Docker Remote API and the --device option to docker run .
This parameter isn't applicable to jobs that are running on Fargate resources. Don't provide it for these jobs.
Type union: either IResolvable or (either IResolvable or CfnJobDefinition.IDeviceProperty)[]
InitProcessEnabled
If true, run an init process inside the container that forwards signals and reaps processes.
public object? InitProcessEnabled { get; set; }
Property Value
Remarks
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 | grep "Server API version"
Type union: either bool or IResolvable
MaxSwap
The total amount of swap memory (in MiB) a container can use.
public double? MaxSwap { get; set; }
Property Value
Remarks
This parameter is translated to the --memory-swap option to docker run where the value is the sum of the container memory plus the maxSwap value. For more information, see --memory-swap details in the Docker documentation.
If a maxSwap value of 0 is specified, the container doesn't use swap. Accepted values are 0 or any positive integer. If the maxSwap parameter is omitted, the container doesn't use the swap configuration for the container instance on which it runs. A maxSwap value must be set for the swappiness parameter to be used.
This parameter isn't applicable to jobs that are running on Fargate resources. Don't provide it for these jobs.
SharedMemorySize
The value for the size (in MiB) of the /dev/shm volume.
public double? SharedMemorySize { get; set; }
Property Value
Remarks
This parameter maps to the --shm-size option to docker run .
This parameter isn't applicable to jobs that are running on Fargate resources. Don't provide it for these jobs.
Swappiness
You can use this parameter to tune a container's memory swappiness behavior.
public double? Swappiness { get; set; }
Property Value
Remarks
A swappiness value of 0 causes swapping to not occur unless absolutely necessary. A swappiness value of 100 causes pages to be swapped aggressively. Valid values are whole numbers between 0 and 100 . If the swappiness parameter isn't specified, a default value of 60 is used. If a value isn't specified for maxSwap , then this parameter is ignored. If maxSwap is set to 0, the container doesn't use swap. This parameter maps to the --memory-swappiness option to docker run .
Consider the following when you use a per-container swap configuration.
By default, the Amazon ECS optimized AMIs don't have swap enabled. You must enable swap on the instance to use this feature. For more information, see <a href="https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/instance-store-swap-volumes.html">Instance store swap volumes</a> in the <em>Amazon EC2 User Guide for Linux Instances</em> or <a href="https://docs.aws.amazon.com/premiumsupport/knowledge-center/ec2-memory-swap-file/">How do I allocate memory to work as swap space in an Amazon EC2 instance by using a swap file?</a>
This parameter isn't applicable to jobs that are running on Fargate resources. Don't provide it for these jobs.
Tmpfs
The container path, mount options, and size (in MiB) of the tmpfs mount.
public object? Tmpfs { get; set; }
Property Value
Remarks
This parameter maps to the --tmpfs option to docker run .
This parameter isn't applicable to jobs that are running on Fargate resources. Don't provide this parameter for this resource type.
Type union: either IResolvable or (either IResolvable or CfnJobDefinition.ITmpfsProperty)[]
