Jenkins碼頭設置

我使用Jenkins來構建項目，但現在我的客戶想要在Docker鏡像中構建內部版本。我已經在服務器上安裝了docker，並在172.0.0.1:PORT上運行。我已經安裝了Docker插件並將此TCP URL分配給Docker URL。我還創建了一個名爲jenkins-1的圖像在configure項目中，我使用Build環境Build with Docker Container並提供圖像名稱。然後在構建放Execute Shell，然後建立它Jenkins碼頭設置

但它給人的錯誤：

Pull Docker image jenkins-1 from repository ...` 
$ docker pull jenkins-1` 
Failed to pull Docker image jenkins-1` 
FATAL: Failed to pull Docker image jenkins-1`
