NetworkMode

class aws_cdk.aws_ecs.NetworkMode(value)

Bases: Enum

The networking mode to use for the containers in the task.

ExampleMetadata:: infused

Example:

ec2_task_definition = ecs.Ec2TaskDefinition(self, "TaskDef",
    network_mode=ecs.NetworkMode.BRIDGE
)

container = ec2_task_definition.add_container("WebContainer",
    # Use an image from DockerHub
    image=ecs.ContainerImage.from_registry("amazon/amazon-ecs-sample"),
    memory_limit_mi_b=1024
)

Attributes

AWS_VPC: The task is allocated an elastic network interface.

BRIDGE: The task utilizes Docker’s built-in virtual network which runs inside each container instance.

HOST

The task bypasses Docker’s built-in virtual network and maps container ports directly to the EC2 instance’s network interface directly.

In this mode, you can’t run multiple instantiations of the same task on a single container instance when port mappings are used.

NAT

The task utilizes NAT network mode required by Windows containers.

This is the only supported network mode for Windows containers. For more information, see Task Definition Parameters.

NONE: The task’s containers do not have external connectivity and port mappings can’t be specified in the container definition.
