Question

我正在尝试在ubuntu笔记本电脑上设置一个牧场环境以进行测试。我正在重现在另一台服务器上运行的步骤（这个与Debian一起运行）以使其运行但我遇到了一些麻烦。

主机是ubuntu 16.0.4。我已经安装了docker-ce。

sudo docker version
Client:
 Version:      18.03.1-ce
 API version:  1.37
 Go version:   go1.9.5
 Git commit:   9ee9f40
 Built:        Thu Apr 26 07:17:20 2018
 OS/Arch:      linux/amd64
 Experimental: false
 Orchestrator: swarm

Server:
 Engine:
  Version:      18.03.1-ce
  API version:  1.37 (minimum version 1.12)
  Go version:   go1.9.5
  Git commit:   9ee9f40
  Built:        Thu Apr 26 07:15:30 2018
  OS/Arch:      linux/amd64
  Experimental: false

一旦跑步，我就让牧场主开始工作：

sudo docker run -d --restart=unless-stopped -p 8080:8080 rancher/server:stable

然后我尝试在同一台机器上创建Host以便能够创建容器：

sudo docker run --rm --privileged -v /var/run/docker.sock:/var/run/docker.sock -v /var/lib/rancher:/var/lib/rancher rancher/agent:v1.2.10 http://192.168.20.213:8080/v1/scripts/adsasdsaddsa:sadsadasd:p7DSjasdasdsadsad

该过程运行没有任何错误。我可以在syslog中看到这个：

当我回到牧场主gui时，我看不到主持人。 docker container ls显示客户端容器正在运行。

我错过了什么？

更新：

如响应中所指出的，用于服务器和客户端之间的相互引用的IP地址可能存在问题。我删除了客户端和服务器并重新启动它。我正在使用172.17.0.1，我相信它是定位器（不是我的局域网IP）。这就是我在日志中看到的内容：

我可以看到与界面定义和激活相关的一些错误，但我不确定它们是否相关。

Answer 1

由于rancher/server和rancher/agent容器都在同一主机上运行，因此您需要指定代理IP。否则，将被错误地检测到。您可以在代理日志中看到这一点：

INFO: ENV: DETECTED_CATTLE_AGENT_IP=172.17.0.1

要解决此问题，请使用docker rm命令删除现有代理容器，然后在UI中使用deactivate和delete主机。更多信息here。

在“添加主机”页面中，指定IP地址以生成正确的注册URL。

参考：https://rancher.com/docs/rancher/v1.6/en/faqs/troubleshooting/#are-the-ips-of-the-hosts-correct-in-the-ui

当地的牧场主不会在gui上看到
