Capistrano 任务未在给定范围内执行。
我已经构建了一些需要在定义的 :app 角色中运行的 capistrano 任务。这是我到目前为止所拥有的：
desc "Stop unicorn"
task :stop, :roles => :app do
logger.info "Stopping unicorn server(s).."
run "touch #{unicorn_pid}"
pid = capture("cat #{unicorn_pid}").to_i
run "kill -s QUIT #{pid}" if pid > 0
end
据我所知，这应该在 :app 角色中给定的服务器上运行给定的命令，对吧？但事实是它以 :db 角色在服务器上运行命令。
任何人都可以深入了解这个问题吗？或者有没有办法强制 Capistrano 遵守 :roles 标志？
提前致谢

I have build some capistrano tasks which I need to run on within the defined :app roles. This is what I have so far:
desc "Stop unicorn"
task :stop, :roles => :app do
logger.info "Stopping unicorn server(s).."
run "touch #{unicorn_pid}"
pid = capture("cat #{unicorn_pid}").to_i
run "kill -s QUIT #{pid}" if pid > 0
end
As far as I know, this should run the given commands on the servers given in the :app role, right? But the fact of the matter is that it's running the commands on the servers in the :db role.
Can anyone give some insight into this problem? Or is there a way to force Capistrano to adhere to the :roles flag?
Thanks in advance

使用 Capture 将导致任务仅在列出的第一台服务器上运行。
从文档中：
捕获助手将在第一个匹配的服务器上执行给定的命令，并将命令的输出作为字符串返回。

不幸的是，我面临着类似的问题，find_servers解决方案可能有效，但它很hacky，并且运行N x N次，其中N在您拥有的服务器数量。
Using Capture will cause the task to be run only on the first server listed.
From the documentation:
The capture helper will execute the given command on the first matching server, and will return the output of the command as a string.

Unfortunately I am facing a similar issue, the find_servers solution may work, but it's hacky, and runs N x N times, where N in the number of servers you have.
