Question

我正在使用docker，所以我通过这个命令行docker run -d --restart=always -p 8080:8080 rancher/server使用了牧场主/服务器我检查了docker containers（docker ps -a）我发现这个：

dc191cba6ce8        rancher/server      "/usr/bin/s6-svscan /"   10 minutes ago      Up 27 seconds       3306/tcp, 0.0.0.0:8080->8080/tcp   naughty_almeida

iptables内容：

Chain ufw-user-input (1 references)
target     prot opt source               destination         
ACCEPT     tcp  --  0.0.0.0/0            0.0.0.0/0            tcp dpt:8080
ACCEPT     udp  --  0.0.0.0/0            0.0.0.0/0            udp dpt:8080

看起来很好，但我无法访问rancher ui页面：

http://IP:8080

docker logs dc191cba6ce8：

Answer 1

DEBUG（所有评论/聊天摘要）：首先，我们检查了它是否是端口映射问题：

docker inspect dc191cba6ce8 | grep IPAddress

哪个给了IP：172.17.x.x 当他能够curl 172.17.x.x:8080输出时：这必须返回类似：

{"type":"collection","resourceType":"apiVersion","links":{"self":"http://172.17.0.6:8080/","latest":"http://172.17.0.6:8080/v1"},"createTypes":{},"actions":{},"data":[{"id":"v1","type":"apiVersion","links":{"self":"http://172.17.0.6:8080/v1"},"actions":{}}],"sortLinks":{},"pagination":null,"sort":null,"filters":{},"createDefaults":{}}

首先我们考虑了端口映射问题。但是，在重新检查日志后，我发现容器启动存在问题： docker logs dc191cba6ce8的输出显示：

2016-07-19 17:58:55,936 INFO    [main] [ConsoleStatus] [1/32] [0ms] [0ms] Loading bootstrap 
2016-07-19 17:58:56,267 INFO    [main] [ConsoleStatus] [2/32] [330ms] [329ms] Loading config-defaults 
2016-07-19 17:59:09,243 INFO    [main] [ConsoleStatus] [3/32] [13307ms] [12976ms] Loading system 
2016-07-19 17:59:09,410 INFO    [main] [ConsoleStatus] [4/32] [13474ms] [166ms] Loading defaults 
2016-07-19 17:59:10,482 INFO    [main] [ConsoleStatus] [5/32] [14546ms] [1072ms] Loading types 
2016-07-19 17:59:21,385 INFO    [main] [ConsoleStatus] [6/32] [26858ms] [736ms] Loading allocator-server

然后停了下来。所以容器启动存在问题。这是因为服务器只有512MB的RAM。在dockerhub上是运行游侠容器的一些先决条件：

RAM: 1GB+

因此，在创建一个更大的服务器（或在本地执行）之后，它能够以适当的方式启动容器并在浏览器中访问控制台。

只需在浏览器中键入dockerhost：{here 443}，如果您使用的是代理，请将其禁用。

使用docker安装后无法访问Rancher UI
