Struct SystemControl

#[non_exhaustive]
pub struct SystemControl {
    pub namespace: Option<String>,
    pub value: Option<String>,
}

A list of namespaced kernel parameters to set in the container. This parameter maps to Sysctls in the docker container create command and the --sysctl option to docker run. For example, you can configure net.ipv4.tcp_keepalive_time setting to maintain longer lived connections.

We don't recommend that you specify network-related systemControls parameters for multiple containers in a single task that also uses either the awsvpc or host network mode. Doing this has the following disadvantages:

• For tasks that use the awsvpc network mode including Fargate, if you set systemControls for any container, it applies to all containers in the task. If you set different systemControls for multiple containers in a single task, the container that's started last determines which systemControls take effect.

• For tasks that use the host network mode, the network namespace systemControls aren't supported.

If you're setting an IPC resource namespace to use for the containers in the task, the following conditions apply to your system controls. For more information, see IPC mode.

• For tasks that use the host IPC mode, IPC namespace systemControls aren't supported.

• For tasks that use the task IPC mode, IPC namespace systemControls values apply to all containers within a task.

This parameter is not supported for Windows containers.

This parameter is only supported for tasks that are hosted on Fargate if the tasks are using platform version 1.4.0 or later (Linux). This isn't supported for Windows containers on Fargate.

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.

namespace: Option<String>

The namespaced kernel parameter to set a value for.

value: Option<String>

The namespaced kernel parameter to set a value for.

Valid IPC namespace values: "kernel.msgmax" | "kernel.msgmnb" | "kernel.msgmni" | "kernel.sem" | "kernel.shmall" | "kernel.shmmax" | "kernel.shmmni" | "kernel.shm_rmid_forced", and Sysctls that start with "fs.mqueue.*"

Valid network namespace values: Sysctls that start with "net.*". Only namespaced Sysctls that exist within the container starting with "net.* are accepted.

All of these values are supported by Fargate.

Implementations

impl SystemControl

pub fn namespace(&self) -> Option<&str>

The namespaced kernel parameter to set a value for.

pub fn value(&self) -> Option<&str>

The namespaced kernel parameter to set a value for.

Valid IPC namespace values: "kernel.msgmax" | "kernel.msgmnb" | "kernel.msgmni" | "kernel.sem" | "kernel.shmall" | "kernel.shmmax" | "kernel.shmmni" | "kernel.shm_rmid_forced", and Sysctls that start with "fs.mqueue.*"

Valid network namespace values: Sysctls that start with "net.*". Only namespaced Sysctls that exist within the container starting with "net.* are accepted.

All of these values are supported by Fargate.

impl SystemControl

pub fn builder() -> SystemControlBuilder

Creates a new builder-style object to manufacture SystemControl.

Trait Implementations

impl Clone for SystemControl

fn clone(&self) -> SystemControl

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SystemControl

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for SystemControl

fn eq(&self, other: &SystemControl) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
