在 capify 中运行另一个任务并指定主机

编辑：重新表述问题

假设您有两项任务。第一个类动态确定主机名，并且只想在该主机上调用第二个类。

task :first_task do
  host_name = ... 
  second_task, :hosts => hostname
end

task :second_task do
  run "some stuff"
end

据我所知，传入 :hosts 不起作用。将新的 host_name 分配给角色，并让第二个任务使用这些角色是可行的，但这不适用于现有任务。这似乎是可能的，因为默认的部署：设置可以传入 HOSTS 变量，但我不知道它是如何工作的。

EDIT: rephrasing the question

Say you have two tasks. The first one determines a host name dynamically, and wants to invoke the second class only on that host.

task :first_task do
  host_name = ... 
  second_task, :hosts => hostname
end

task :second_task do
  run "some stuff"
end

As far as I can tell passing in :hosts doesn't work. Assigning the new host_name to a role, and having the second task use those roles would work, but that won't work on existing tasks. This does seem to be possible as the default deploy:setup works on passing in a HOSTS variable, but I can't figure out how that works.

好吧，有点晚了，但是......你可以尝试：

task :first_task do
  host_name = ... 
  set :hosts, host_name
  second_task
end

task :second_task do
  run "some stuff", :hosts => fetch(:hosts)
end

Well, a bit late for it to matter, but... You could try:

task :first_task do
  host_name = ... 
  set :hosts, host_name
  second_task
end

task :second_task do
  run "some stuff", :hosts => fetch(:hosts)
end
