擷取實例資訊

提出 GET "/metadata/v1/instance" 請求以擷取實體的詳細資訊。

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

回應會列出實例的所有詳細資料，包括網路介面、計算設定檔及磁區連接。

擷取實體初始化資訊

您可以透過 GET /metadata/v1/instance/initialization 請求，以程式化的方式擷取實體的初始化資訊。 請參閱下列範例。

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)'

在範例中，指令的回傳值是使用者資料，由 jq 擷取並置於 user_data 環境變數中。

回應會列出在實體初始化時使用的公開 SSH 金鑰，並擷取任何其他在實體佈建時可用的使用者資料。 回應包括識別 SSH 金鑰的 SHA256 值。
