jenkins和docker：没有指定uri
我已经在jenkins中安装了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build一个图像。
它将这个消息转储给我：

编辑这是我的docker.serviceconfiguration文件与连接有关：
ExecStart=/usr/bin/docker daemon -H fd:// -H tcp://127.0.0.1:4243 -H unix:///var/run/docker.sock
Docker正在收听：
netstat -tupln | grep 4243 tcp 0 0 127.0.0.1:4243 0.0.0.0:* LISTEN
我已经使用了Docker Builderconfiguration，并且已经将Docker URL设置为http://127.0.0.1:4243 。 Test connection告诉我：
Something went wrong, cannot connect to tcp://127.0.0.1:4243, cause: null
我也使用这个命令curl -XGET http://localhost:4243/containers/json向API REST发出了一个请求，结果是正确的：

当我点击Test Connection时，我也复制了日志信息。 消息是完全一样的，尽pipe我已经指定了uri：

随着jenkins版本2.51和docker版本1.13.1 ，您可以做以下解决这个问题。 首先将以下内容添加到ExecStart （在docker.service ）：
ExecStart=/usr/bin/dockerd -H tcp://127.0.0.1:4243 -H unix:///var/run/docker.sock
然后去jenkins – >pipe理jenkins – >configuration系统 – >dockerbuild设者 。 您在此指定：
tcp://127.0.0.1:4243
作为Docker URL。 应用和testing连接。
我刚刚遇到这个问题。
对我来说，它是点击Advanced和设置Docker version为1.11
快速浏览/var/log/jenkins/jenkins.log显示：
WARNING: client version 1.11 is too old. Minimum supported API version is 1.12, please upgrade your client to a newer version
删除它，点击应用/重新加载，然后Test connection工作。
