在Jenkins中構建Docker映像（在Docker映像中）-Cloud Docker Agent

Question

我嘗試學習如何配置Jenkins（在Docker容器中）以基於Dockerfile構建Docker映像。

首先，我安裝了DockerToolbox。 （OS Windows 7家庭版）

然后，我從Dockerhub中提取了最新的Jenkins映像，運行了容器並以管理員身份登錄。

基於此教程： https : //www.katacoda.com/courses/jenkins/build-docker-images我嘗試將插件配置為與Docker主機/守護程序通信。 （第3步）

在（Jenkins / configure / Cloud部分）中，我必須填寫Name和Docker-Url，然后填寫Test Connection。

在Docker終端中，我鍵入docker-machine config以獲取Url。

不幸的是，在測試連接后，我在下面得到異常：

我不確定是否缺少某些內容，或者是否有更有效的方法。

預先感謝您的提示。

感謝您關注Katacoda方案。 聽起來好像Docker Daemon沒有在HTTPS端口上監聽。 docker-machine命令將返回Docker VM的IP地址，但默認情況下，該守護程序不偵聽HTTPS端口，而僅通過Unix套接字偵聽。

當您在同一台計算機上時，可以嘗試使用諸如unix:///var/run/docker.sock或/var/run/docker.sock類的東西來代替IP / Port。

如果要使用IP /端口，則需要修改Docker Daemon設置，使用boot2docker可以通過https://github.com/docker/machine/issues/3859完成
