Question

我已经在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。

它向我转发了这条消息：

有什么想法吗？

修改这是与connection：

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正在听：

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

我已经进行了Docker Builder配置，并且我已将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

Answer 1

使用ExecStart的jenkins版本和docker版本ExecStart=/usr/bin/dockerd -H tcp://127.0.0.1:4243 -H unix:///var/run/docker.sock，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tcp://127.0.0.1:4243（在docker.service中）：

item.setShowAsAction(MenuItem.SHOW_AS_ACTION_COLLAPSE_ACTION_VIEW);
item.setActionView(new View(getApplicationContext()));

然后转到 Jenkins - ＆gt;管理Jenkins - ＆gt;配置系统 - ＆gt; Docker构建器。在这里指定：

{{1}}

作为Docker URL。申请并测试连接。

Answer 2

Docker-build-step插件不使用本地docker安装自动。

*您必须手动配置*

正如在其他答案中提到的那样，您不需要为Docker终结点启用tcp的巫毒，您只需使用套接字路径即可。

在Manage Jenkins/Configure System/Docker Builder中您将看到Docker URL选项留为空白。用unix套接字URL unix:///var/run/docker.sock填充它。那应该可以解决问题。

Answer 3

我刚遇到这个问题。

对我而言，点击Advanced并将Docker version设为1.11

快速了解/var/log/jenkins/jenkins.log透露：

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apply / reload，然后Test connection工作。
