jenkins和码头工人：未指定uri

我在jenkins安装了docker,jenkins和docker-build-step.

我已经设置了一个步骤,以便从我的存储库的Dockerfile构建一个图像.

它把这个消息转发给我：

有任何想法吗？

编辑
这是我的与连接相关的docker.service配置文件：

ExecStart=/usr/bin/docker daemon -H fd:// -H tcp://127.0.0.1:4243 -H unix:///var/run/docker.sock

Docker正在倾听：

netstat -tupln | grep 4243
tcp        0      0 127.0.0.1:4243          0.0.0.0:*               LISTEN

我已经使用了Docker Builder配置,并将Docker URL设置为http://127.0.0.1:4243.测试连接告诉我：

Something went wrong,cannot connect to tcp://127.0.0.1:4243,cause: null

我还使用此命令curl -XGET http：// localhost：4243 / containers / json向API REST发出请求,结果是正确的：

      }
    ]
  }
]

我点击Test Connection时也复制了日志信息.尽管我已经指定了uri,但消息完全相同：

最佳答案

使用jenkins版本的2.51和docker版本1.13.1,您可以执行以下操作来解决此问题.首先将以下内容添加到ExecStart(在docker.service中)：

ExecStart=/usr/bin/dockerd -H tcp://127.0.0.1:4243 -H unix:///var/run/docker.sock

然后去Jenkins – >管理Jenkins – >配置系统 – > Docker构建器.
在这里你指定：

tcp://127.0.0.1:4243

作为Docker URL.应用并测试连接.
