returning a value from a provision script to vagrant

Question

Is it possible to return a value from a provision script back to vagrant?

response = config.vm.provision( \"shell\", path: \"script.sh\" )

if response = \'o         


        

Answer 1

I was able to get it from the VMs by doing this way:

On Windows:

config.trigger.after :provision do |trigger|
    trigger.name = "create token"
    trigger.run = {"inline": "vagrant ssh --no-tty -c 'hostname' master01 > test.txt"}
end

On Mac:

config.trigger.after :provision do |trigger|
  trigger.name = "create token"
  trigger.run = {"inline": "/bin/bash -c 'vagrant ssh --no-tty -c "hostname" master01 > test.txt'"}
end

This will dump the output of the command from the VM to the given file in CWD on the host.

Notes:

• About bash redirection - why '/bin/bash -c' is required? (here in case of Mac) - https://github.com/hashicorp/vagrant/issues/10674
• I am using Vagrant 2.2.6
