SSHKit doesn't prescribe how you connect to your servers, so if you have a
SSHKit::Host which has a special property ("tryFirst: true"), and then you
write a task which pre-flights that server, and that server alone, then you
are in luck, or in the naïve example below, split them into two lists
I would be tempted to make a Ruby class (or a function, your call) to
perform teh chef run, and do smoething like this:
checkHost = 'one'
hosts = %w{two three}
# could also be wrapped into a class
def chefit(context, host)
context.on(host) do |h|
return context.test("chef solo")
end
end
task :chefit do
# grab the first host, and see if this worked
if chefit(binding, checkHost)
chefit(binding, hosts)
end
end
Something like this, (no warranty, haven't tested, etc)
