Ошибка в NetworkInterfaces в CfnNetworkInterface

2 голосов
/ 01 апреля 2020

Я пытаюсь сгенерировать файл CloudFormation с C#. К сожалению, все, что я передаю как NetworkInterfaces в CfnInstance, я получаю сообщение об ошибке. Я просмотрел всю документацию и не смог найти решение своей проблемы.

Вот мой C# стек. 

public class CFStack : Amazon.CDK.Stack
    {
        public CFStack(Construct parent, string id) : base(parent, id)
        {
            var vpc = new CfnVPC(this, "VPC", new CfnVPCProps()
            {
                CidrBlock = "10.0.0.0/16",
                EnableDnsHostnames = true,
                EnableDnsSupport = true,
                InstanceTenancy = "default"
            });

            var sg = new CfnSecurityGroup(this, "SG", new CfnSecurityGroupProps()
            {
                GroupDescription = "CF Security group",
                GroupName = "CF SG",
                VpcId = vpc.Ref,
            });

            var subnet = new CfnSubnet(this, "Subnet", new CfnSubnetProps()
            {
                CidrBlock = "10.0.0.0/24",
                MapPublicIpOnLaunch = true,
                VpcId = vpc.Ref,
            });

            new CfnSecurityGroupIngress(this, "ingress", new CfnSecurityGroupIngressProps()
            {
                GroupId = sg.Ref,
                FromPort = 3389,
                ToPort = 3389,
                CidrIp = "213.155.147.202/32",
                IpProtocol = "tcp"
            });

            new CfnSecurityGroupEgress(this, "egress", new CfnSecurityGroupEgressProps()
            {
                GroupId = sg.Ref,
                FromPort = 80,
                ToPort = 444,
                CidrIp = "0.0.0.0/0",
                IpProtocol = "tcp",
            });

            var blockmapping = new CfnInstance.BlockDeviceMappingProperty()
            {
                DeviceName = "/dev/sdh",
                Ebs = new CfnInstance.EbsProperty()
                {
                    VolumeType = EbsDeviceVolumeType.GP2.ToString(),
                    DeleteOnTermination = true,
                    VolumeSize = 65,
                }
            };

            var networkInterface = new CfnNetworkInterface(this, "NetworkInterface", new CfnNetworkInterfaceProps()
            {
                GroupSet = new[] { sg.ToString() },
                SubnetId = subnet.Ref
            });

            new CfnInstance(this, "EC2", new CfnInstanceProps()
            {
                NetworkInterfaces = new[] { networkInterface },
                BlockDeviceMappings = new[] { blockmapping },
                ImageId = "ami-id",
                InstanceType = "m5.xlarge",
                KeyName = "keyName",
                UserData = "test"
            });
        }
    }

К сожалению, трассировка стека исключительной ситуации не проясняет ситуацию. Вот сама трассировка стека:

Я также пытался передать 

NetworkInterfaces = networkInterface
NetworkInterfaces = networkInterface.ToString()
NetworkInterfaces = new[] {networkInterface}
NetworkInterfaces = new[] {networkInterface.ToString()}

Если я удаляю NetworkInteraces свойство из CfnNetworkInterface приведенный выше код работает нормально.

Я не могу понять, в чем проблема. Все, что я изменяю, приводит к тому же исключению из вышесказанного. Любая помощь с благодарностью.

Заранее спасибо.

Мне удалось воссоздать и исправить проблему с API, используя TypeScript. Я был в состоянии синтезировать стек. Я считаю, что то же самое применимо в C#. 

new CfnInstance(this, "EC2", {
  networkInterfaces: [{
    deviceIndex: '0',
    groupSet: [sg.toString()],
    subnetId: subnet.ref
  }],
  imageId: "ami-id",
  instanceType: "t2.micro",
  keyName: "keyName",
  userData: "test"
});

Проблема заключается в использовании CfnNetworkInterface в CfnInstance. Свойство networkInterfaces в CfnInstance ожидает массив типа CfnInstance.NetworkInterfaceProperty или cdk.IResolvable. То, что вы предоставляете ему прямо сейчас (CfnNetworkInterface), не соответствует ожидаемому типу. Я также был озадачен, увидев, что я не смог импортировать CfnInstance.NetworkInterfaceProperty в своем коде TS выше, но смог привести нотацию объекта к IResolvable.

Также обратите внимание, что при использовании CfnInstance.NetworkInterfaceProperty вы также должны указать deviceIndex. Надеюсь, это решит вашу проблему в C# коде.

PS: я удалил blockDeviceMappings из моего подхода для краткости
