Printing final message at end of Vagrantfile that creates multiple VMs

Juan Jiménez
I want to puts a message at the very end of all processing of my Vagrantfile, but I can't use the config.vm.post_up_message because I am creating three vm's in a dev cluster and I don't want the message shown three times. Any ideas?

Alvaro Miranda Aguilera
on the last VM block, say its "web01" you can put

web01.vm.post_up_message

Re: Printing final message at end of Vagrantfile that creates multiple VMs

There is only one VM block and a loop to create the three VM's. They are essentially identical, with small differences, so no point in copying everything three times. That is why this solution does not work.

Re: Printing final message at end of Vagrantfile that creates multiple VMs

Alvaro Miranda Aguilera
you can *if* on the loop

say you loop 0 to 2 on a var i

web01.vm.post_up_message = "hello" if i==2



please share the vagrantfile so I can test and share a working example

Re: Printing final message at end of Vagrantfile that creates multiple VMs

yes its a ruby format

but you can add the message you want to this block:

      when 3
        node.vm.provision "shell", path: "./provision/consulagent2.sh"
        node.vm.provision "shell", path: "./provision/nomadclient2.sh"
        # <here the message you want>
