Hi,

I've written a rack application using grape which calls knife's bootstrap

command to bootstrap a VM.The following is the code to bootstrap

module Chef

class Bootstrap < Grape::API

format :json

content_type :json,"application/json"

params do

requires :VM_IP, :type => String, :desc => "ip value"

requires :VM_username, :type => String, :desc => "username"

requires :VM_password, :type => String, :desc => "password"

end

resource :virtualmachine

post 'bootstrap' do

content_type "application/json"

status "200"

body "Boostrapped Successfully!!!"

t1 = Thread.new do

system "knife chefsolo bootstrap #{params[:VM_IP]} -x

#{params[:VM_username]} -P '#{params[:VM_password]}'"

end

end

end

end

end

When i start the app manually using "rackup -p 9000 config.ru",the above code

is working fine,I've added this command to /etc/rc.local file to start the

service during startup. The service has been started successfully but

bootstrapping is not working. I've tried replacing the knife commands with

other system commands and those are working fine.Only knife commands are not

working when i start the service in the background.Is there any specific reason

for it?How can i modify the code to make that working?

What's the failure? Can you modify your code to run knife with the -VV option and share the output?
