Is it possible to pass an OR conditional into the :only check? I know that
it expects an array of key/value pairs so you can essentially do an AND
inside of the hash, but what if you want to check on multiple keys in the
conditional?
Example:
I have ten servers in a bank that are all serving the application. At any
point in time, only the :primary and the :secondary should have actions
performed on them. Through capistrano definitions I have managed to pass
:primary => true and :secondary => true into those two servers, such that
(stripped all the other servers out of the array to save space):
[
#<Capistrano::ServerDefinition:0x101968618
@hash=-2051751815,
@host="server21.domain.com",
@options={:secondary=>true},
@port=nil,
@to_s="[email protected]",
@user="user">,
#<Capistrano::ServerDefinition:0x10194ad98
@hash=6964762022,
@host="server20.domain.com",
@options={:primary=>true},
@port=nil,
@to_s="[email protected]",
@user="user">,
#<Capistrano::ServerDefinition:0x10194cb20
@hash=-447395779,
@host="server22.domain.com",
@options={},
@port=nil,
@to_s="[email protected]",
@user="user">,
]
If I want to run a task *only* on those two (the list is much longer, just
stripped for this example), is there some iteration of :only that allows me
to do that? I have attempted:
task :test, :roles => [:app], :only => {:primary => true} || {:secondary =>
true} do; run "hostname"; end
But it only executes on the first matching hash of k,v pair. And of
course, if you do:
task :test, :roles => [:app], :only => {:primary => true, :secondary =>
true} do; run "hostname"; end
It will attempt to match both k,v pairs. Anyone have any suggestions?
It's probably just something syntactical that I'm totally overlooking.
Thanks in advance,
Chris.
