Chef : run jenkins agent as a background process on a node
I'm running this command manually on console, java -jar agent.jar -jnlpUrl {{master_url}}/computer/{{slave_name}}/slave-agent.jnlp -secret {{secret_key}} > /dev/null 2>&1 &
basically it is starting the jenkins slave in background and it works fine, now when i try to do the same thing in Chef, the chef-client process hangs and gets timed out because process never goes in background and session remains active.
command = Mixlib::ShellOut.new("java -jar agent.jar -jnlpUrl {{master_url}}/computer/{{slave_name}}/slave-agent.jnlp -secret {{secret_key}}" > /dev/null 2>&1 &")
command.run_command
ruby unix jenkins process chef

You really should be using a proper service layer for this, which is systemd in all modern Linux distros.

Instead of using JNLP method OR creating a custom service for this i tried using SSH method to launch slaves from master. It's working fine now. Anyways, thanks for your input :)
