AWS CDK | Get ECS Fargate service/Task assigned public IP

I'm trying to get the assigned public IP address of an ECS service but I couldn't find a way to reference it.

const backendService = new ecs.FargateService(
      this,
      "EcsBackendAppService",
      {
        cluster: backendCluster,
        taskDefinition: backendTaskDefinition,
        desiredCount: 1,
        assignPublicIp: true,
        securityGroups: [vpcDefaultSecurityGroup],

        serviceName: "backend",
      }
    );

Is it possible to get the public IP in CDK?

Solution

  • No, it is not possible, because the public IP address will be different for each task that ECS launches - if the task is restarted for any reason, the IP will change.
