/AWS1/CL_ECSSYSTEMCONTROL

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.

CONSTRUCTOR

IMPORTING

Optional arguments:

iv_namespace TYPE /AWS1/ECSSTRING /AWS1/ECSSTRING

The namespaced kernel parameter to set a value for.

iv_value TYPE /AWS1/ECSSTRING /AWS1/ECSSTRING

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.

Queryable Attributes

namespace

Accessible with the following methods

Method Description
GET_NAMESPACE() Getter for NAMESPACE, with configurable default
ASK_NAMESPACE() Getter for NAMESPACE w/ exceptions if field has no value
HAS_NAMESPACE() Determine if NAMESPACE has a value
