Mendapatkan data tentang jenis instans Amazon EC2 menggunakan SDK AWS

Contoh kode berikut ini menunjukkan cara mendapatkan data tentang tipe instans Amazon EC2.

Contoh-contoh tindakan adalah kutipan kode dari program yang lebih besar dan harus dijalankan di dalam konteks. Anda dapat melihat tindakan ini dalam konteks pada contoh kode berikut:

/// <summary> /// Describe the instance types available. /// </summary> /// <returns>A list of instance type information.</returns> public async Task<List<InstanceTypeInfo>> DescribeInstanceTypes(ArchitectureValues architecture) { var request = new DescribeInstanceTypesRequest(); var filters = new List<Filter> { new Filter("processor-info.supported-architecture", new List<string> { architecture.ToString() }) }; filters.Add(new Filter("instance-type", new() { "*.micro", "*.small" })); request.Filters = filters; var instanceTypes = new List<InstanceTypeInfo>(); var paginator = _amazonEC2.Paginators.DescribeInstanceTypes(request); await foreach (var instanceType in paginator.InstanceTypes) { instanceTypes.Add(instanceType); } return instanceTypes; }

Contoh 1: Untuk menjelaskan tipe instans

Contoh describe-instance-types berikut menampilkan detail untuk tipe instans tertentu.

aws ec2 describe-instance-types \ --instance-types t2.micro

Output:

{ "InstanceTypes": [ { "InstanceType": "t2.micro", "CurrentGeneration": true, "FreeTierEligible": true, "SupportedUsageClasses": [ "on-demand", "spot" ], "SupportedRootDeviceTypes": [ "ebs" ], "BareMetal": false, "Hypervisor": "xen", "ProcessorInfo": { "SupportedArchitectures": [ "i386", "x86_64" ], "SustainedClockSpeedInGhz": 2.5 }, "VCpuInfo": { "DefaultVCpus": 1, "DefaultCores": 1, "DefaultThreadsPerCore": 1, "ValidCores": [ 1 ], "ValidThreadsPerCore": [ 1 ] }, "MemoryInfo": { "SizeInMiB": 1024 }, "InstanceStorageSupported": false, "EbsInfo": { "EbsOptimizedSupport": "unsupported", "EncryptionSupport": "supported" }, "NetworkInfo": { "NetworkPerformance": "Low to Moderate", "MaximumNetworkInterfaces": 2, "Ipv4AddressesPerInterface": 2, "Ipv6AddressesPerInterface": 2, "Ipv6Supported": true, "EnaSupport": "unsupported" }, "PlacementGroupInfo": { "SupportedStrategies": [ "partition", "spread" ] }, "HibernationSupported": false, "BurstablePerformanceSupported": true, "DedicatedHostsSupported": false, "AutoRecoverySupported": true } ] }

Contoh 2: Untuk memfilter tipe instans yang tersedia

Anda dapat menentukan filter guna mencakup hasil untuk tipe instans yang memiliki karakteristik khusus. Contoh describe-instance-types berikut mencantumkan tipe instans yang mendukung hibernasi.

aws ec2 describe-instance-types --filters Name=hibernation-supported,Values=true --query InstanceTypes[].InstanceType

Output:

[ "m5.8xlarge", "r3.large", "c3.8xlarge", "r5.large", "m4.4xlarge", "c4.large", "m5.xlarge", "m4.xlarge", "c3.large", "c4.8xlarge", "c4.4xlarge", "c5.xlarge", "c5.12xlarge", "r5.4xlarge", "c5.4xlarge" ]
