Struct LinuxParameters

#[non_exhaustive]
pub struct LinuxParameters {
    pub capabilities: Option<KernelCapabilities>,
    pub devices: Option<Vec<Device>>,
    pub init_process_enabled: Option<bool>,
    pub shared_memory_size: Option<i32>,
    pub tmpfs: Option<Vec<Tmpfs>>,

}

The Linux-specific options that are applied to the container, such as Linux KernelCapabilities.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

capabilities: Option<KernelCapabilities>

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 the add parameter is only supported if using platform version 1.4.0 or later.

devices: Option<Vec<Device>>

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.

init_process_enabled: Option<bool>

Run an init 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}}'

shared_memory_size: Option<i32>

The value for the size (in MiB) of the /dev/shm volume. This parameter maps to the --shm-size option to docker run.

If you are using tasks that use the Fargate launch type, the sharedMemorySize parameter is not supported.

tmpfs: Option<Vec<Tmpfs>>

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.

max_swap: Option<i32>

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.

swappiness: Option<i32>

This allows you to tune a container's memory swappiness behavior. A swappiness value of 0 will cause swapping to not happen unless absolutely necessary. A swappiness value of 100 will cause pages to be swapped very aggressively. Accepted values are whole numbers between 0 and 100. If the swappiness parameter is not specified, a default value of 60 is used. If a value is not specified for maxSwap 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.

Implementations

impl LinuxParameters

pub fn capabilities(&self) -> Option<&KernelCapabilities>

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 the add parameter is only supported if using platform version 1.4.0 or later.

pub fn devices(&self) -> &[Device]

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.

If no value was sent for this field, a default will be set. If you want to determine if no value was sent, use .devices.is_none().

pub fn init_process_enabled(&self) -> Option<bool>

Run an init 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}}'

pub fn shared_memory_size(&self) -> Option<i32>

The value for the size (in MiB) of the /dev/shm volume. This parameter maps to the --shm-size option to docker run.

If you are using tasks that use the Fargate launch type, the sharedMemorySize parameter is not supported.

pub fn tmpfs(&self) -> &[Tmpfs]

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.

If no value was sent for this field, a default will be set. If you want to determine if no value was sent, use .tmpfs.is_none().

pub fn max_swap(&self) -> Option<i32>

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.
