Syncing Files with Vagrant

Use the config.vm.synced_folder option to set up file syncing based on the parameters from the instructions:

 Vagrant.configure("2") do |config|
   config.vm.box = "fgrehm/trusty64-lxc"
   config.vm.define "app" do |app|
     app.vm.provider :lxc do |lxc|
       lxc.container_name = 'app'
     end
   end
   config.vm.synced_folder "/home/cloud_user/wanderer/app", "/opt/wanderer", type: "rsync",
     id: "wanderer-app", rsync__auto: true
 end

Save and exit.

Deploy the Vagrant environment:

vagrant up

We can SSH into the guest container to see that the sync worked:

vagrant ssh
ls /opt/wanderer/
exit

Since we are using rsync, auto-synced must be turned on:

vagrant rsync-auto &

Take note of the process ID output.

Update the application; here changing Do This! to To-Do:

vim app/views/index.ejs

    To-Do

Save and exit; notice the output from Vagrant.

Kill the auto-sync process:

pkill PID_OUTPUT

Stop the container:

vagrant halt
