如何在命令行中检查特定git分支的最新提交哈希？

我在Route 53中遇到域名托管问题.

我需要重定向xyz.com到www.xyz.com,所以我在Route 53上创建了一个Hosted Zone.我添加了一条A记录,其中包含我的ELB地址,以及一个CNAME,其名称www.xyz.com和我的ELB地址的值.

但是这个设置不会将我的裸域重定向到我的www前缀域.我该如何解决这个问题？

我已经配置了厨师环境,我可以使用capistrano部署我的应用程序.现在我想让我的厨师处理capistrano来部署我的应用程序.怎么做到呢 ？

我是graylog2的新手.我安装了graylog2和web界面.我从其他服务器获取TCP syslog到graylog服务器.但是我无法将Rails日志从其他服务器发送到Graylog.

在graylog服务器中,我正在侦听端口12201的GELF HTTP日志,并且所有必需的端口都是打开的.但我没有得到graylog服务器的任何输入.我已将Rails记录器配置如下:

#config/environments/staging.rb

config.lograge.enabled = true    
config.lograge.log_format = :graylog2     
config.logger = GELF::Logger.new("graylogserverexample.com",
                                12201, "WAN",{
                                :host => "hostname",
                                :facility => "railslog"})    

任何帮助,将不胜感激.

我使用kops版本1.8.0-beta.1创建了RBAC启用的kubernetes集群,我正在尝试运行一个nginx pod,它应该附加预先创建的EBS卷并且pod应该启动.但即使我是管理员用户,也要获得未经授权的问题.任何帮助将受到高度赞赏.
