- Enclosing class:
CfnTaskDefinition
This parameter maps to Sysctls
in tthe docker conainer 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 setsystemControls
for any container, it applies to all containers in the task. If you set differentsystemControls
for multiple containers in a single task, the container that's started last determines whichsystemControls
take effect. - For tasks that use the
host
network mode, the network namespacesystemControls
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 namespacesystemControls
aren't supported. - For tasks that use the
task
IPC mode, IPC namespacesystemControls
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 AWS Fargate if the tasks are using platform version
1.4.0
or later (Linux). This isn't supported for Windows containers on Fargate.
Example:
// The code below shows an example of how to instantiate this type. // The values are placeholders you should change. import software.amazon.awscdk.services.ecs.*; SystemControlProperty systemControlProperty = SystemControlProperty.builder() .namespace("namespace") .value("value") .build();
