# NetworkLoadBalancedTaskImageProps

Options for configuring a new container.

- Source: [`aws-ecs-patterns/lib/base/network-multiple-target-groups-service-base.ts`](https://github.com/aws/aws-cdk/blob/v2.275.0/packages/aws-cdk-lib/aws-ecs-patterns/lib/base/network-multiple-target-groups-service-base.ts#L119)

## Example

```ts
// Two network load balancers, each with their own listener and target group.
declare const cluster: ecs.Cluster;
const loadBalancedEc2Service = new ecsPatterns.NetworkMultipleTargetGroupsEc2Service(this, 'Service', {
  cluster,
  memoryLimitMiB: 256,
  taskImageOptions: {
    image: ecs.ContainerImage.fromRegistry("amazon/amazon-ecs-sample"),
  },
  loadBalancers: [
    {
      name: 'lb1',
      listeners: [
        {
          name: 'listener1',
        },
      ],
    },
    {
      name: 'lb2',
      listeners: [
        {
          name: 'listener2',
        },
      ],
    },
  ],
  targetGroups: [
    {
      containerPort: 80,
      listener: 'listener1',
    },
    {
      containerPort: 90,
      listener: 'listener2',
    },
  ],
});
```

## Properties

- `containerName`: string = none — The container name value to be specified in the task definition.

- `containerPorts`: number[] = [80] — A list of port numbers on the container that is bound to the user-specified or automatically assigned host port.

  If you are using containers in a task with the awsvpc or host network mode, exposed ports should be specified using containerPort.
  If you are using containers in a task with the bridge network mode and you specify a container port and not a host port,
  your container automatically receives a host port in the ephemeral port range.

  Port mappings that are automatically assigned in this way do not count toward the 100 reserved ports limit of a container instance.

  For more information, see
  [hostPort](https://docs.aws.amazon.com/AmazonECS/latest/APIReference/API_PortMapping.html#ECS-Type-PortMapping-hostPort).

- `dockerLabels`: { [key: string]: string } — A key/value map of labels to add to the container.

  **Default:** No labels.

- `enableLogging`: boolean = true — Flag to indicate whether to enable logging.

- `environment`: { [key: string]: string } — The environment variables to pass to the container.

  **Default:** No environment variables.

- `executionRole`: [IRole](/cdk/api/v2/docs/aws-cdk-lib.aws_iam.IRole.html) — The name of the task execution IAM role that grants the Amazon ECS container agent permission to call AWS APIs on your behalf.

  **Default:** No value

- `family`: string — The name of a family that this task definition is registered to.

  **Default:** Automatically generated name.

  A family groups multiple versions of a task definition.

- `image`: [ContainerImage](/cdk/api/v2/docs/aws-cdk-lib.aws_ecs.ContainerImage.html) (required) = none — The image used to start a container.

  Image or taskDefinition must be specified, but not both.

- `logDriver`: [LogDriver](/cdk/api/v2/docs/aws-cdk-lib.aws_ecs.LogDriver.html) — The log driver to use.

  **Default:** AwsLogDriver if enableLogging is true

- `secrets`: { [key: string]: [Secret](/cdk/api/v2/docs/aws-cdk-lib.aws_ecs.Secret.html) } — The secrets to expose to the container as an environment variable.

  **Default:** No secret environment variables.

- `taskRole`: [IRole](/cdk/api/v2/docs/aws-cdk-lib.aws_iam.IRole.html) — The name of the task IAM role that grants containers in the task permission to call AWS APIs on your behalf.

  **Default:** A task role is automatically created for you.
