Beispiel 1: So beschreiben Sie einen Instance-Typ
Im folgenden
describe-instance-types
-Beispiel werden die Details für den angegebenen Instance-Typ angezeigt.aws ec2 describe-instance-types \ --instance-types
t2.micro
Ausgabe:
{ "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 } ] }
Weitere Informationen finden Sie unter Instance-Typen im Amazon Elastic Compute Cloud-Benutzerhandbuch für Linux-Instances.
Beispiel 2: So filtern Sie die verfügbaren Instance-Typen
Sie können einen Filter angeben, um die Ergebnisse auf Instance-Typen mit einem bestimmten Merkmal zu beschränken. Im folgenden
describe-instance-types
-Beispiel werden die Instance-Typen aufgeführt, die den Ruhezustand unterstützen.aws ec2 describe-instance-types \ --filters
Name=hibernation-supported,Values=true
--query 'InstanceTypes[*].InstanceType
'Ausgabe:
[ "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" ]
