Jenkins与Docker插件java.lang.NullPointerException:未指定uri

Question

我正在尝试使用Jenkins的Docker插件.但是Jenkins无法访问REST API.

在Jenkins配置中,我放置了Docker REST URL:http://127.0.0.1:4243当点击测试连接时,它给了我Something went wrong, cannot connect to http://127.0.0.1:4243, cause: null

但是当我登录用户jenkins su jenkins并做curl 127.0.0.1:4243/info一切按预期工作时.我开始使用Docker -H tcp://127.0.0.1:4243 -H unix:///var/run/docker.sock.

我究竟做错了什么？

有同样的问题,对我来说这是一个愚蠢的小事.

为新版本输入URI:http://127.0.0.1:4243或2375,然后在测试连接之前单击" 先应用".
