Task
A list of namespaced kernel parameters to set in the container. This parameter maps to `Sysctls` in tthe 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 FARGATElong if the tasks are using platform version`1.4.0`or later (Linux). This isn't supported for Windows containers on Fargate.
Properties
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.*"` All of these values are supported by Fargate.
