ipcMode

The IPC resource namespace to use for the containers in the task. The valid values are `host`, `task`, or `none`. If `host` is specified, then all containers within the tasks that specified the `host` IPC mode on the same container instance share the same IPC resources with the host Amazon EC2 instance. If `task` is specified, all containers within the specified task share the same IPC resources. If `none` is specified, then IPC resources within the containers of a task are private and not shared with other containers in a task or on the container instance. If no value is specified, then the IPC resource namespace sharing depends on the Docker daemon setting on the container instance. If the `host` IPC mode is used, be aware that there is a heightened risk of undesired IPC namespace expose. If you are setting namespaced kernel parameters using `systemControls` for the containers in the task, the following will apply to your IPC resource namespace. For more information, see System Controls in the Amazon Elastic Container Service Developer Guide.

• For tasks that use the `host` IPC mode, IPC namespace related `systemControls` are not supported.

• For tasks that use the `task` IPC mode, IPC namespace related `systemControls` will apply to all containers within a task. This parameter is not supported for Windows containers or tasks run on FARGATElong.
