如何从AWS实例确定操作系统？

Question

我通过使用AWS -SDK.EC2.description information获取AWS实例信息，以下是数组中的一个元素：

 stdout: {
 stdout: AmiLaunchIndex: 0,
 stdout: ImageId: 'ami-00d03ffa3b3757af2',
 stdout: InstanceId: 'i-09167c582a8d016ae',
 stdout: InstanceType: 'r5.4xlarge',
 stdout: KeyName: 'interos-prod',
 stdout: LaunchTime: 2019-08-20T18:01:14.000Z,
 stdout: Monitoring: { State: 'disabled' },
 stdout: Placement: {
 stdout: AvailabilityZone: 'us-west-2c',
 stdout: GroupName: '',
 stdout: Tenancy: 'default'
 stdout: },
 stdout: PrivateDnsName: 'ip-xxx-31-9-xxx.us-west-2.compute.internal',
 stdout: PrivateIpAddress: '172.31.9.226',
 stdout: ProductCodes: [],
 stdout: PublicDnsName: 'ec2-54-xxx-226-xxx.us-west-2.compute.amazonaws.com',
 stdout: PublicIpAddress: '54.201.xxx.xxx',
 stdout: State: { Code: 16, Name: 'running' },
 stdout: StateTransitionReason: '',
 stdout: SubnetId: 'subnet-f3ee49a9',
 stdout: VpcId: 'vpc-7e338d07',
 stdout: Architecture: 'x86_64',
 stdout: BlockDeviceMappings: [ [Object] ],
 stdout: ClientToken: '',
 stdout: EbsOptimized: true,
 stdout: EnaSupport: true,
 stdout: Hypervisor: 'xen',
 stdout: ElasticGpuAssociations: [],
 stdout: ElasticInferenceAcceleratorAssociations: [],
 stdout: NetworkInterfaces: [ [Object] ],
 stdout: RootDeviceName: '/dev/sda1',
 stdout: RootDeviceType: 'ebs',
 stdout: SecurityGroups: [ [Object] ],
 stdout: SourceDestCheck: true,
 stdout: Tags: [ [Object], [Object] ],
 stdout: VirtualizationType: 'hvm',
 stdout: CpuOptions: { CoreCount: 8, ThreadsPerCore: 2 },
 stdout: CapacityReservationSpecification: { CapacityReservationPreference: 'open' },
 stdout: HibernationOptions: { Configured: false },
 stdout: Licenses: []
 stdout: },

有人知道吗？我想弄清楚它是ubuntu还是amazon-linux，或者其他什么操作系统。

Answer 1

参考：https://docs.aws.amazon.com/cli/latest/reference/ec2/describe-images.html

您应该能够在第3行查询映像ID？"ImageId：'ami-00d03ffa3b3757af2'“--> aws ec2 describe-images --image-ids ami-00d03ffa3b3757af2和说明应能提供您需要的信息

Answer 2

您可能需要查询AMI(Amazon机器映像) Id以获取更多信息。

尝尝这个

describe-images --image-ids yourImageId

在响应中，您可以查找kernel-id
