检索实例信息

提出 GET "/metadata/v1/instance" 请求，以获取有关实例的详细信息。

curl -X GET "$vpc_metadata_api_endpoint/metadata/v1/instance?version=2025-04-22" -H "Authorization: Bearer $instance_identity_token"

响应列出实例的所有详细信息，包括网络接口，计算概要文件和卷连接。

检索实例初始化信息

您可以通过 GET /metadata/v1/instance/initialization 请求，以编程方式检索实例的初始化信息。 请参阅以下示例。

curl -X GET "$vpc_metadata_api_endpoint/metadata/v1/instance/initialization?version=2025-04-22" -H "Authorization: Bearer $instance_identity_token" | jq -r '(.user_data)'

在示例中，命令的返回值是用户数据，由 jq 提取并放入 user_data 环境变量中。

响应会列出实例初始化时使用的 SSH 公钥，并提取实例供应时可用的任何其他用户数据。 响应包含用于标识 SSH 密钥的 SHA256 值。
