对于AWS elastic beanstalk eb cli，请执行eb tags——list

对于c++(使用cURL):

    #include <curl/curl.h>

    //// cURL to string
    size_t curl_to_str(void *contents, size_t size, size_t nmemb, void *userp) {
        ((std::string*)userp)->append((char*)contents, size * nmemb);
        return size * nmemb;
    };

    //// Read Instance-id 
    curl_global_init(CURL_GLOBAL_ALL); // Initialize cURL
    CURL *curl; // cURL handler
    CURLcode res_code; // Result
    string response;
    curl = curl_easy_init(); // Initialize handler
    curl_easy_setopt(curl, CURLOPT_URL, "http://169.254.169.254/latest/meta-data/instance-id");
    curl_easy_setopt(curl, CURLOPT_WRITEFUNCTION, curl_to_str);
    curl_easy_setopt(curl, CURLOPT_WRITEDATA, &response);
    res_code = curl_easy_perform(curl); // Perform cURL
    if (res_code != CURLE_OK) { }; // Error
    curl_easy_cleanup(curl); // Cleanup handler
    curl_global_cleanup(); // Cleanup cURL

对于Windows实例:

(wget http://169.254.169.254/latest/meta-data/instance-id).Content

or

(ConvertFrom-Json (wget http://169.254.169.254/latest/dynamic/instance-identity/document).Content).instanceId

运行这个:

curl http://169.254.169.254/latest/meta-data/

您将能够看到aws提供的不同类型的属性。

最新的Java SDK有EC2MetadataUtils:

在Java中:

import com.amazonaws.util.EC2MetadataUtils;
String myId = EC2MetadataUtils.getInstanceId();

在Scala中:

import com.amazonaws.util.EC2MetadataUtils
val myid = EC2MetadataUtils.getInstanceId

如果你想在python中获取所有实例id列表，下面是代码:

import boto3

ec2=boto3.client('ec2')
instance_information = ec2.describe_instances()

for reservation in instance_information['Reservations']:
   for instance in reservation['Instances']:
      print(instance['InstanceId'])
